Description
FIELD OF THE INVENTION
The present invention pertains to telephony communications systems
and has particular application to methods including software
enabling extended management capabilities of state and interaction
of a remote knowledge worker from a contact center using
voice-based technologies.
BACKGROUND OF THE INVENTION
In the field of computer-telephony-integrated (CTI) telephony
communication, there have been many improvements in technology over
the years that have contributed to more efficient use of telephone
communication within hosted call-center environments.
In recent years, advances in computer technology, telephony
equipment, and infrastructure have provided many opportunities for
improving telephone service in public-switched and private
telephone intelligent networks. Similarly, development of a
separate information and data network known as the Internet,
together with advances in computer hardware and software have led
to a new multimedia telephone system known in the art by several
names. In this new system telephone calls are simulated by
multimedia computer equipment, and data, such as audio data, is
transmitted over data networks as data packets. In this system the
broad term used to describe such computer-simulated telephony is
Data-Network-Telephony (DNT) of which
Internet-Protocol-Network-Telephony (IPNT) is a sub-set.
Conventional non-DNT telephony systems are referred to herein as
Connection-Oriented-Switched-Telephony COST systems.
Recent improvements to available technologies associated with the
transmission and reception of data packets during real-time DNT
communication have enabled companies to successfully add DNT,
principally IPNT, capabilities to existing CTI call centers. Such
improvements, as described herein and known to the inventor,
include methods for guaranteeing available bandwidth or quality of
service (QoS) for a transaction, improved mechanisms for
organizing, coding, compressing, and carrying data more efficiently
using less bandwidth, and methods and apparatus for intelligently
replacing lost data via using voice supplementation methods and
enhanced buffering capabilities.
In addition to Internet protocol (IPNT) calls, a DNT center may
also share other forms of media with customers accessing the system
through their computers. E-mails, Video mails, fax, file share,
file transfer, video calls, and so forth are some of the other
forms of media, which may be used. This capability of handling
varied media leads to the term multimedia communications center. A
multimedia communications center may be a combination CTI and DNT
center, or may be a DNT center capable of receiving COST calls and
converting them to a digital DNT format. The term communication
center will replace the term call center hereinafter in this
specification when referring to multimedia capabilities.
In typical communication centers, DNT is accomplished by Internet
connection and IPNT calls. For this reason, IPNT and the Internet
will be used in examples to follow. It should be understood,
however, that this usage is exemplary, and not limiting.
Keeping contact histories, reporting statistics, creating routing
rules and the like becomes more complex as newer types of media are
added to communication center capability. Additional hardware
implementations such as servers, processors, etc. are generally
required to aid full multimedia communication and reporting.
Therefore, it is desirable that interactions of all multimedia
sorts be analyzed, recorded, and routed according to enterprise
(business) rules in a manner that provides seamless integration
between media types and application types, thereby allowing agents
to respond intelligently and efficiently to customer queries and
problems.
A customer-interaction network operating system for managing
interactions in a multimedia communication center is known to the
inventors and described in disclosure of U.S. Pat. No. 6,108,711
with reference to the cross-reference section of this
specification. The system has an external media layer for managing
media contact between customers and the communication center, a
workflow layer for processing customer interactions and routing
events to enterprise agents and knowledge workers; and an internal
media layer for managing media contact with the agents and
knowledge workers. The workflow layer captures each transaction,
prepares a text version of at least a portion of each non-text
transaction, and extracts knowledge from the text transaction or
text version of a non-text transaction to be stored in a knowledge
base for later use in routing and other management functions. All
transactions, text versions, and extracted knowledge is related in
storage for future analysis and use.
Due to modernization of contact centers and to incorporation of
full multimedia capabilities and recovery capabilities of contact
history, a new breed of center agent has emerged that can provide
assistance with specialized skill-based knowledge that conventional
center operative personnel do not normally possess. This newer type
of agent is termed a knowledge worker (KW) in the art.
A knowledge worker, weather an agent or specialized technician,
generally has all of the resource in the way of customer data,
interaction data, product data, and multimedia support at his
fingertips as long as he or she is operating from a designated
PC/VDU or other supported station within the communication center.
In some cases, a knowledge worker may have full data access and
multimedia support if he is located off-site but is linked to the
center by a suitable data-network connection such as from a home
office or remote station.
When a knowledge worker is away from a home-center such as on the
road, or at a client location, he is generally limited in data
access and interaction capability with his or her home
communication-center data and tools. In some cases this may be a
liability to the center. In many cases she/he will be limited to
specific data that was carried along, or that may be downloaded
from the center to such as a cellular telephone, a personal digital
assistant (PDA) or a Laptop computer. Moreover, a mobile knowledge
worker in the field may also be limited in providing service to the
home-center by virtue of the same data-access limitations.
In typical contact centers, which may also include multimedia
communication centers, the preponderance of incoming and outgoing
interactions are processed by voice (DNT) or Web-based self service
interfaces or by communication-center agents located within the
domain of the center and managed through a communication center
environment. However, many interactions cannot be successfully
processed through client self-service interfaces or on-site agents
often because of a high level of assistance required. Such
interactions require the expertise of a knowledge worker.
Knowledge workers are not required for routine service assistance
or other duties that are routinely performed within the domain of
the center. As a result, they are typically located off site in a
pool or remote to the extent of performing as a home-based or
traveling workers. Therefore, standard communication center control
systems and procedures cannot be applied to such knowledge workers.
Often this problem is due to an absence of a CTI link established
between the location of the knowledge worker and the communication
center.
Off-site knowledge workers are mobile and typically operate using a
variety of communication equipment (non-CTI telephone, personal
digital assistants [PDAs], wireless Web, etc.) and using
applications that are not assimilated in standard or unified array
throughout the communication environment. Therefore, it becomes
increasingly difficult to provide management from the communication
center in terms of state control and report accessibility.
Remote knowledge workers are, from a control and management
standpoint, invisible to standard CTI-enabled facilities. Not
having the ability to manage these workers causes the ongoing costs
associated with doing business from a communication center to
rise.
The inventors are familiar with certain hardware/software methods
for providing access to communication center facilities using
telephony switch control or other first-party control methods. In
these methods call center services are supported by cooperation
between software at the CTI processor and the computer platform at
the remote station. In one embodiment the data link, once
established, is kept open while calls continue to be switched to
the remote station. In another embodiment after an initial agent
log in, dial up is done from the remote station upon detecting
calls from the call center by a TAPI compliant device. A reduced
log is performed at the CTI processor at the call center to save
time. In yet another method, the CTI processor establishes the data
connection each time using a modem bank adapted for dialing. The
modem bank switches the call from the call center to the remote
station. A plurality of remote stations may be thus supported.
A drawback with these system types is that it requires first-party
control equipment established at the remote agent workplace. The
first-party control equipment controls the remote agent phone
separately from the agent's computer platform.
A proxy system is known to the inventor and described in disclosure
of U.S. patent application Ser. No. 09/405,335 listed in the
cross-reference section of this specification. This system enables
a worker remote from a communication center and limited to a light
computer device unable to operate as a workstation at the
communication center to operate with full access to data and
software at the communication center. A proxy server, core to the
system, has a two-way data link to the light computer device
operated by the remote agent, and executes software, which
ascertains the hardware and software characteristics of the light
device. The proxy server accesses communication center data at
direction from the light device, operates communication center
software tools, and provides results to the light device over the
communication link in a form usable by the light device.
The proxy server accesses communication-center data at direction of
the light device, operates communication center software tools, and
provides results to the light device over the communication link in
a form usable by the light device. This approach suggests a general
method for management of remote knowledge workers from within a
contact center (CC). In particular, it suggests using a proxy
server as a mediator between a contact center environment and a
remote agent device. However, it is still limited in terms of
further enhancement that might enable more specific techniques and
mechanisms. Part of this solution includes a remote option that
requires special equipment to be provided and connected to the
remote agent's telephone set, which in addition, must be a
specially adapted telephone set to accept the equipment.
Some enhancement is provided over the proxy system by yet another
system known to the inventors and referenced in this specification
as U.S. patent application Ser. No. 10/269,124. This system is a
network system for managing remote agents of a communication
center. The system includes a primary server connected to the
network the primary server controlling at least one routing point.
The system has one or more secondary servers distributed on the
network and accessible to the remote agents, the secondary server
or servers have data access to agent computing platforms and
communication peripherals. The system utilizes a software suite
distributed in part to the secondary server or servers and
distributed in part to one or more agents computing platforms and
peripherals, the software suite includes protocol for reporting
agent status data. The system monitors agents computing platforms
and peripherals for activity state through the one or more
secondary servers. The one or more secondary servers exchange
control messaging and event related data using ISCC supported
protocols with the primary server over the network for intelligent
routing purposes.
While the above-described system provides full and unfettered
access to communication-center data and services for a mobile or
otherwise remote knowledge worker, such interaction is limited in
terms of control signaling and interaction management that might be
initiated from the side of the knowledge worker.
What is clearly needed is a system and methods for managing remote
knowledge workers using state-or-art voice technologies that enable
human-to-application control and interaction.

some cases the telephones are cellular telephones.
In still other cases the voice-capable devices are one of an IP
telephone, a personal digital assistant, or a computer telephony
application, and in others the server application uses
XML-Style-Sheet-Language-Transformation for transforming VXML to
XML-based languages. In yet other cases the data sourced from
center applications includes center-archived data and data related
to active telephony events, and in others the VXML scripts are
generated from VXML templates during active interaction and
executed immediately thereafter in event routing scenarios.

optionally, event-related data, from the routing point to the
remote agent's telephone based on at least the reported state
information and optional caller interaction is provided, comprising
steps of (a) connecting to and interacting with a predetermined
telephone number dialed from the agent telephone, the number
registered to a gateway application, the interaction therewith
comprising at minimum prompted vocalization of the agent state
reported thereto; (b) recognizing at the gateway the vocalization
of state information and populating one or more data fields of a
VXML script with a text version of the state information reported;
(c) transforming the language of the script to one or more
languages understood at the routing point rendering the information
available to the routing point; (d) receiving an incoming event
destined for the remote agent at the routing point and optionally,
interacting with the caller from the routing point to obtain event
related data; (e) routing the event to the agent telephone,

telephone and the connection method is wireless. In some other
preferred embodiments, in step (a), the agent telephone is a plain
old telephony service (POTS) telephone and the connection is made
through normal public-switched-telephone channels. In still others,
in step (a), the gateway application is associated with a
VXML-enabled Web server. In yet others, in step (b), the gateway
uses automated speech recognition to interpret vocalized state
information.
In some embodiments, in step (b), the VXML script is generated by
the Web server, and in others, in step (c), language transformation
includes use of XSLT and is performed by a Web server application.
In still other embodiments, in step (c), a Web server serves the

is performed using XSLT by a Web application. In still other cases,
in step (g), the telephone connection is established and script
execution is performed by a VXML-enabled gateway, and in still
others, in step (g), executing the script results in voice
synthesis of the populated dialogue fields of the script played
over the telephone connection.
In some other cases of this method, in step (g), the telephone is
not the same telephone used to pick-up the related call routed in
association with the event related data, and in others, in step
(g), the agent is already connected to the caller and places the
caller on hold to receive the event related data on the same
telephone.
In yet another aspect of the present invention, in a VXML-based
telephone communication system, a method for alerting a remote
service agent to activate a networked workstation that is currently
offline to receive an automated data update or service
configuration is provided, comprising steps of (a) providing a text
rendering comprising the alert to a VXML-enabled server; (b)
transforming the text rendering to a form useable in a VXML script;
and (c) establishing a telephone connection with the agent and
executing the script once connected.
In some preferred embodiments of this method, in step (a), the text
alert is a request from a communications application, the request
tied to an activity threshold detected by the application. In other
preferred embodiments, in step (a), the application is a load
balancing application and the activity threshold quantifies a
current call load. In yet other preferred embodiments, in step (a),
the server is a Web server the alert uploaded thereto from a
contact center.
Also in some preferred embodiments of this method, in step (a), the
alert is rendered in the form of XML. In others, in step (b),
transformation includes use of XSLT and is performed by a Web
server application. In yet others, in step (b), a VXML script is
generated containing the alert. In still others, in step (c),
wherein the connection is established by a VXML-enabled gateway
associated with the server.
In still further embodiments of this method, in step (c), the
connection is established to a cellular telephone through a
wireless network, and in still further embodiments, in step (c),
the connection is established to a plain old telephony service
(POTS) telephone and the connection is made through normal
public-switched-telephone channels. In still others, in step (c),
the telephone connection is established and script execution is
performed by a VXML-enabled gateway.
In some, in step (c), executing the script may result in voice
synthesis of the populated dialogue fields of the script played
over the telephone connection, and in other cases, in step (c),

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 is an exemplary overview of a multimedia-interaction storage
system within communication-center architecture 9 according to an
embodiment of the present invention. Communication center 9 is
illustrated solely for the purpose of illustrating just one of many
possible system architectures in which the invention may be
practiced. Center 9, which in a preferred embodiment comprises both
conventional and data-network telephony (DNT) apparatus, is
exemplary of an architecture that could facilitate a network
operating system such as CINOS (known to the inventor).
Communication center 9 may be assumed to have all the internal
components described in the background section such as agent
workstations with LAN connected PC/VDUs, agent's COST telephones,
and so on. Such a communication center operating an enhanced
interaction network operating system such as CINOS would employ
knowledge workers trained to interact with associates, clients, and
in some cases internal systems that require programming, scripting,
researching, and the like.
For the purposes of this specification, a knowledge worker (KW) is
a highly skilled individual that is at least trained in systems
programming and implementation using software tools. A KW is also
typically trained in the use of all supported communication media
and applications that may be used with a network operating system.
In many instances, a KW may also handle high level sales and
service while functioning as an agent for the communication center
both inside the center and at a client's location. However, as
described in the background section, a KW away from home (in the
field) will not generally have full access to all communication
center data and tools unless he/she carries a powerful computer
station along, or commandeers a client's station having suitable
connectivity and ability to perform all of the applications at the
home station. Therefore, having many such highly skilled workers in
the field and not in the communication center may be, at times, a
considerable liability to the communication center, but unavoidable
at times. It is to this aspect that the present invention mostly
pertains.
Referring again to FIG. 1, a multimedia data-storage system
represented herein by a centralized grouping of connected and
labeled text blocks is provided and adapted to facilitate
rules-based storage of all communication-center interaction between
agents and clients including co-workers and associates. Such a
representation illustrates an important part of CINOS function.
At the heart of the storage system is a mass-storage repository 11
adapted to store multimedia interactions as well as text-based
related files. Repository 11 may utilize any form of digital
storage technology known in the art such as Raid-Array, Optical
Storage, and so on. The storage capacity of repository 11 will
depend directly on its implementation with regard to the size of
communication center 9 and predicted amount of data that will be
stored and kept by the system.
In this example, repository 11 is divided logically into two
sections. One section, multimedia information system (MIS) 15, is
responsible for storing copies and records of all multimedia
interactions, defined as media that is not text-based, such as
audio, video, and graphics-based media. All multimedia interactions
are stored in MIS 15 whether incoming, outgoing, or internal. A
second section, herein referred to, as text section 13 is
responsible for all text-based interactions as well as text
versions and annotations related to non-text files.
Repository 11 is connected to a communication-center local area
network (LAN) 45. Repository 11 is accessible via LAN 45 to
authorized personnel within a communication center such as agents,
KWs, or the like using computerized workstations connected on the
LAN, and may, in some instances, also be made available, in full or
in part, to clients and associates communicating with the call
center. A network router (RTN) 19 is shown connected to LAN 45 via
network connection 41. In this example, network router 19 is the
first point within a communication center wherein data network
telephony (DNT) media arrives. Network router 19 is exemplary of
many types of routers that may be used to route data over LAN 45.
An Internet-protocol-network-telephony (IPNT) switch 35 is
connected to network router 19 via a data link. IPNT switch 35
further routes or distributes live IPNT calls that do not require
routing to a live agent. IPNT calls that are routed to live agents
are sent over connection 41 to LAN 45 where they reach agent
PC/VDU's at agent and KW workstations connected to the LAN (PC/VDU
is exemplary) or DNT-capable phones (not shown) as illustrated via
directional arrows.
In the multimedia storage system represented herein, a KW such as
one operating at a provided work station (PC/VDU 17) typically has
access to all multimedia interaction histories that are stored in
repository 11. CINOS applications (not shown) executable on
workstations such as PC/VDU 17 empowers the KW to facilitate many
tasks in the realm of communication center functionality. Such
tasks include, but are not limited to, researching and creating
virtually any type of system report regarding data held in
repository 11, updating and creating new management applications
that may alter or enhance CINOS functionality, and other such
system-administrator-type duties. LAN 45 is the network through
which the "in-house" KW is empowered to access such as a CINOS MGR
server 29, repository 11, and other connected data sources and
systems (not shown) that may be present in a communication center
such as center 9.
By reviewing capabilities of the multimedia storage system of
communication center 9, a full appreciation of the necessity of
various in-house skills possessed by a KW, such as the skill of
operating at station 17, may be acquired by one with skill in the
art. Therefore, a detailed review of communication-center
operation, particularly storing interactions follows.
Creating text-based versions of non-text multimedia transactions
may, in some cases, be accomplished by an automated method. For
example, a digital voice attendant 37 is provided and linked to
IPNT switch 35. Digital voice attendant 37 may be of the form of a
DNT-capable IVR or other digital voice-response mechanism as may be
known in the art. Such automated attendants may interact with a
voice caller instead of requiring a live agent. A speech-to-text
converter 39 is provided and linked to voice attendant 37. As
digital voice attendant 37 interacts with a caller, speech-to-text
converter 39 converts the speech to text. Such text may then be
stored automatically into text section 13 of repository 11 and
related to the also-recorded audio data. Part of the purpose and
rationale for the creation of text documents related to non-text
files is that text can be more easily mined for content and meaning
than non-text files.
It will be apparent to one with skill in the art that as speech
recognition technologies are further improved over their current
state, which is adequate for many implementations, reliable text
versions of audio transactions are not only possible but also
practical. Such speech-to-text conversions are used here only for
the convenience of automation wherein no live attendant is needed
to transcribe such audio data. The inventor is familiar with such
converters as used in such as the CINOS system incorporated herein
by reference. Such converters provide convenience in transaction
recording but are not specifically required to achieve the
interaction storage objectives of communication center 9. A KW such
as one operating from station 17 may be called upon to create and
set-up the various rules-based applications that are required for
routing and determining when digital voice attendant 37 will
interface with a client or associate.
An automated services system 43 is provided and has a direct
connection to section 13 of data repository 11. System 43 is
adapted to handle automated interaction and response for certain
text-based interactions such as e-mails, facsimiles, and the like,
wherein a complete text record of the interaction may be mirrored,
or otherwise created and stored into text section 13. For example,
a fax may be sent and mirrored into section 13 or, perhaps
recreated using an optical character recognition (OCR) technique
and then entered. Physical text-documents such as legal papers and
the like may be automatically scanned, processed by OCR techniques,
and then entered into text section 13 before they are sent to
clients. There are many possible automated techniques for creating
and entering text files into a database including methods for
generating automated responses. A KW such as one operating at
station 17 may be called upon to oversee the creation and operation
of all automated services insuring such as prompt response time,
queue management, accurate threading and organization into a
database, updating or adding enhanced capability, and so on.
With respect to the dual telephony capability (COST/DNT) of
communication center 9, a central telephony switch 21 is provided
to be a first destination for COST calls arriving from, for
example, a PSTN network. Switch 21 may be a PBX, ACD, or another
known type of telephony switch. Internal COST-wiring 31 connects
telephony switch 21 to agent's individual telephones (not shown).
Switch 21 is enhanced by a computer-telephony integration (CTI)
processor 25 running an instance of a T-server CTI suite and an
instance of a Stat-server, which are software enhancements known to
the inventor. Such enhancements provide CTI applications, such as
intelligent routing, statistical analysis routines, and so on.
CINOS as previously described and disclosed in the co pending prior
application incorporated herein is adapted to be integrated with
such software when present in a CINOS-enhanced
communication-center. A KW such as one operating station 17 may be
called upon to compile and analyze results provided from
statistical analysis routines executed at processor 25 for the
purpose of creating new routing rules of routines that further
enhance functionality.
An intelligent peripheral in the form of a COST IVR 23 is provided
for the purpose of interacting with callers seeking information and
the like who do not require connection to a live agent at the
communication center. IVR technology may comprise voice response,
touch tone interaction, or a combination of such known
technologies. IVR 23 is linked to processor 25 and also to
automated services 43. An example of an IVR interaction may take
the form of a presentation to a caller from the PSTN of options for
using an automated service such as those described above, or
perhaps waiting for a live agent. A KW such as a KW operating at
station 17 may be called upon to create and install appropriate
interaction scripts into IVR 23 for interaction with clients and
associates calling in from the PSTN.
A CTI to DNT interface 27 is provided for the purpose of converting
COST data to digital mode compatible with DNT so as to be adapted
for digital storage and interaction according to CINOS
functionality and enterprise business rules. Bi-directional arrows
illustrated between interface 27 and IVR 23 represent the ability
to route interactions in either direction. COST to DNT conversion
may be accomplished in IVR 23 in addition to or in place of
interface 27. The connection architecture presented herein is
exemplary only.
A speech-to-text converter 33 is provided for converting audio from
the CTI side to text for entering into text section 13 as was
taught with regard to converter 39 on the DNT side. Actual recorded
media interactions are illustrated entering MIS 15 after text
versions are rendered and entered into section 13 however this is
not required. In some instances text versions of multimedia
interactions may be rendered after the interaction is stored. There
is no limitation regarding sequence. It is sufficient to say that
converters 39 and 33 are capable of real-time conversion and
entry.
Server 29 shown connected to LAN 45 is adapted to host a CINOS MGR
(operating system) application, which provides control and
organization with regard to various functions provided by the CINOS
system as a whole. The storage architecture represented herein by
the described text blocks, and all it encompasses in this
embodiment, is meant only to be an example architecture as may be
dedicated to the storage and organization of communication-center
data according to enterprise rules.
It will be appreciated by one with skill in the art that a network
operating system including a system for automatically storing and
recording virtually all communication center transactions requires
substantial skill in set-up, implementation, and administration
both on the COST side and the DNT side within a communication
center such as center 9. Moreover, a substantial network operating
system such as CINOS has client-side software applications that
subscribers or associates must utilize in order to achieve full
seamless interaction with agents and subsystems operating according
to the system parameters. In some cases, the operating system may
span several communication centers over a large technical campus
connected by a WAN. This fact requires that system administrators
and troubleshooters be available to assist in facilitating and
preparing client and associate CPE for interacting with
communication center equipment and software according to system
parameters.
If a KW such as one operating at station 17 could be mobilized to
operate effectively outside of communication center 9 such as at a
client location, and still be able to service center 9 from the
field, then an enterprise hosting center 9 and perhaps other like
centers could save considerable resources associated with training
and expenses incurred for maintaining a larger number of fixed
KW's.
The inventor provides a method and apparatus whereby such a mobile
KW could have full and unfettered access to virtually all data
systems and sources housed within his home communication center
without having to carry a powerful station or inconveniencing a
client by commandeering client resources. This inventive method and
apparatus is described below in enabling detail.
FIG. 2 is a block diagram illustrating a connective relationship
between a proxy server 49 and a hand-held computer 47 operated by a
mobile KW according to a preferred embodiment of the present
invention.
Hand-held computer 47 has a CPU 63, a memory 57, a video adapter
circuitry 55, and a modem 65 all communicating on bus 59. Video
circuitry 55 drives a display 61. Memory 57 may be any of a number
of types, such as flash, random access (RAM), read-only (ROM) or
similar type, or a combination of these. There may be other
components as well, but these are not shown to facilitate
description of the unique aspects of this embodiment of the
invention. The hardware arrangement is intentionally shown as
general, and is meant to represent a broad variety of
architectures, which depend on the particular computing device
used. Possibilities include many types of portable hand-held
computers and also adapted cellular phones capable of receiving and
sending video. A mobile KW would use such as device for
communication and data access while in the field.
Proxy-Server 49 is a relatively sophisticated and powerful computer
typical of computers used as WEB servers, although the use in this
embodiment of Proxy-Server 49 is not the conventional or typical
functions of a WEB server as known in the art. Proxy-Server 49 has
a CPU 69, a memory 71, and a means of connecting to a data network
such as the Internet. The network connecting means in this
embodiment is a modem 67 communicating on a bus 73. In other
embodiments the network connecting means may be a network adapter
or other.
Modem 67 in the embodiment shown is compatible with modern 65 in
computer 47. A communication link 66, which may be facilitated by a
telephone line or a wireless connection, facilitates communication
between computer 47 and server 49. The means of connection and
communication can be any one of several sorts, such as a telephone
dial-up, an Internet connection through an ISP, or a cell telephone
connection, wireless IP networks or other wireless link, including
private cell or wireless WAN or LAN. A communication port 75
connects to communication link 77 providing communication, in this
case, through the Internet, to a suitable station or server in
communication center 9 of FIG. 1. In this example, the linked
station is preferably the KW's own home-center workstation or
PC/VDU 17 from FIG. 1.
Port 75 and link 77 may also be any one of several types, or a
combination of types. In some embodiments, server 49 and station 17
will be nodes on a local area network (LAN) covering a large
technical campus, and the link between the two servers will be a
serial network link with port 75 being a LAN card according to any
of a number of well-known protocols. In other embodiments link 77
may be a telephone line, and port 75 will be a dial-up telephone
modem. In still other embodiments, this link could be a parallel
communication link. This link could also be through the Internet or
other wide area network.
Proxy-Server 49 exists in this embodiment of the invention to
perform functions enabling hand-held computer 47 to operate as an
apparently powerful web-browsing machine, even though the
stand-alone capability of computer 47 will not even begin to
support such functionality. As is well known in the art, for a
computer to be a fully functional web-browsing system requires a
high-performance CPU and execution of relatively sophisticated
web-browsing and display applications. Such a computer typically
has to operate, as described above, at or above a million
instructions per second.
Proxy-Server 49 executes a program 53 the inventor terms an
Inter-Browser. The Inter-Browser combines functionality of a
conventional web browser with special functions for recognition of
and communication with hand-held computer 47. Commands from
computer 47, such as, for example, a command to access a WEB page
on the World Wide Web, or a server or station such as station 17
within a home communication center such as center 9, are received
by Proxy-Server 49 operating the Inter-Browser program, and acted
upon as though they are commands received from a conventional input
device such as a keyboard.
Following the example of a command communicated over link 66 from
computer 47 for accessing station 17, shown herein and in FIG. 1,
Proxy-Server 49 accesses the appropriate server (in this case
station 17) over link 77, and transmits the appropriate data over
link 77. Proxy-Server 49 therefore has HTML and TCP/IP capability
for accessing source data over the Internet. By hosting other
routines that allow interface with data systems, data sources and
such as station 17, a KW may have full access to virtually any type
of data or software tools that he could access from his station if
he were operating from within center 9.
Proxy-Server 49, instead of displaying the downloaded data (or
playing video and/or audio output, as the case may be, depending on
the downloaded data), translates the data to a simpler
communication protocol and sends the data in a TCP/IP protocol to
computer 47 for output over link 66. Link 66 becomes a dedicated
TCP/IP pipe to and from Proxy-Server 49. Proxy-Server 49 thus acts
as a proxy for computer 47, performing those functions of WEB
browsing and data download that computer 47 cannot perform under
its own computing power.
Computer 47, through execution of a program the inventor terms a
NanoBrowser 51 sends commands entered at computer 47 over link 66
to Proxy-Server 49 and accepts data from Proxy-Server 49 to be
displayed on display 61. Data is transferred in a protocol the
inventor terms HT-Lite. The NanoBrowser also provides for
interactive selection of links and entry into fields in displays,
as is typical for WEB pages displayed on a computer screen. The
NanoBrowser provides for accepting such entry, packaging data
packets in TCP/IP form, and forwarding such data to Proxy-Server
49, where much greater computer power provides for efficient
processing.
One of the processing tasks that has to conventionally occur at the
browser's computer is processing of received data into a format to
be displayed on whatever display the user has. There are, as is
well known in the art, many types of displays and many display
modes. These range all the way from relatively crude LCD displays
to high-resolution, multi-color displays. There are, in addition, a
number of other functions that have to be performed conventionally
at a user's computer to interact effectively with the WWW. For
example, audio and video and some other functions typically require
supplemental, or helper, applications to be installed on or
downloaded to a field unit to process audio and video data and the
like.
Most data transferred by WEB servers assumes relatively high-end
displays, such as color SVGA displays as known in the art. Data
accessed through the Internet from such as MIS database 15 of FIG.
1 would also assume a high-end display and large file size
dependent on the type of media accessed. In PDAs, cellular video
phones, and digital organizers, such as those anticipated for use
in the present invention, the displays are relatively low
resolution, and are typically LCD in nature. In the system
described with the aid of FIGS. 1 and 2, inter-Browser program 53
at Proxy-Server 49 and the HT-Lite Nano-Browser 51 at hand-held
unit 47 cooperate in another manner as well. When one connects to
the Proxy-Server the hand-held unit, through the HT-Lite
NanoBrowser program, provides a signature, which the Proxy-Server
compares with logged signatures.
An ID match when connecting a hand-held unit to the Proxy-Server
provides the Proxy-Server with information about the hand-held
unit, such as CPU type and power, screen size, type and resolution,
presence of a pointer device, and sound capability. The
Proxy-Server then uses this specific information to translate HTML
and other files from the Internet to a form readily usable without
extensive additional processing by the hand-held unit. For a small
monochrome LCD display a 60 k/70 k JPEG file becomes a 2 k/4 k bit
map, for example. Also, multi-file pages are recombined into single
file pages. This translation also minimizes bandwidth requirement
for link 66, and speeds transmission of data. In this way, a mobile
KW may have access to all types of data sourced at his or her home
communication center. Through proxy server 49, a KW may also
initiate and receive multimedia interactions including high-end
transactions while operating unit 47.
It is in this ability of the Proxy-Server to do the heavy
computing, of which the translation of HTML files is a single
example, that is responsible for a unique ability of hand-held
devices in practicing embodiments of the present invention to
accomplish functions that they could not otherwise accomplish, and
to do so without inordinate usage of stored energy. In various
embodiments of the present invention, hand-held devices with CPUs
having an ability to run at from 0.001 to 0.05 MIPs can serve as
WEB browsers, displaying WEB pages and allowing users to initiate
on-screen links and to input data into input fields. Given the
above example of MIPs requirement for WEB browsing, where currently
available solutions may provide a 5.times. advantage, practicing
the present invention can provide an advantage of up to
2000.times., resulting in battery life approaching 2 weeks (given a
100 g battery weight), where expected battery life for similar
functionality with a powerful CPU was calculated as 8 minutes.
As a given example of an instance wherein a mobile KW may provide
full service to a home center, consider the following: Assume a
mobile KW from center 9 of FIG. 1 is at a client premise installing
network software and therefore not at center 9. He opens his or her
hand-held device 47 and plugs in to a nearby telephone jack for the
purpose of establishing a connection to proxy server 49, which in
this case, may be implemented anywhere on the Internet. While he is
configuring software on a client's computer, an important call from
communication center 9 arrives through server 49 (hosted by the
enterprise) to his hand-held 47. The call is pre-processed at proxy
server 49 by Inter-Browser 53 and transmitted over link 66 to
device 47 where it is displayed according to device parameters and
rules associated with Nanno-Browser 51.
Suppose that the call requests that the KW rewrite a script used in
such as digital voice attendant 37 because the current message has
become corrupted or is not playing properly. The KW may then
initiate a multimedia call to his resident workstation such as
station 17 (FIG. 1) through proxy 49 by way of link 77. The call
would arrive at router 19 and be routed directly over link 41 to
station 17 based on identity thus by-passing normal DNT call
handling routines. Part of the call includes a command to allow the
KW to control the operation of station 17 by proxy. He may then use
command keys to cause Inter-Browser 53 to browse a list of
pre-prepared DNT scripts stored at station 17. Such a list may
appear as a text summary on such as display 61 of device 47. The KW
may then scroll through and select a script thus issuing a command
to station 17 (by proxy) to access attendant 37 (FIG. 1) and
replace the message which is overwritten by the new one.
It will be apparent to one with skill in the art that there are a
wide variety of interaction possibilities by virtue of the method
and apparatus of the present invention. In the cited example, a DNT
call was made to the KW's computing device 47. Therefore, proxy 49
acts in one aspect as a call router. In another embodiment, a KW
may accept a cellular call or a COST call and respond to the
request-using device 47.
In still another embodiment, a KW operating a portable device such
as device 47 may temporarily plug in to any connected LAN network
such as may be found connecting a large technical campus or the
like. Upon plugging in, the KW may initiate an outbound-call to
server 49 in the Internet and receive a temporary IP address and
device authentication for communicating with such as center 9.
To practice the invention, given an accessible WEB server
configured as a Proxy-Server according to an embodiment of the
present invention, one needs only to load HT-Lite NanoBrowser
software on a computer and to provide Internet access for the
computer, such as by a telephone modem. In many cases, candidate
computers have built-in modems. In other cases, an external modem
may be provided and connected. In the case of hand-held devices,
such as PDAs and organizers, some have an ability to load software
via a serial port, a PC card slot, through the modem extant or
provided, or by other conventional means. In some cases, all
operating code is embedded, that is, recorded in read-only memory.
In some of these cases, adding HT-Lite routines may require a
hardware replacement. In virtually all cases of hand-held devices,
however, the necessary routines can be provided.
One of the components of the HT-Lite Nano-Browser software (51) is
a minimum browser routine termed by the inventor a Nano-Browser.
The Nano-Browser is capable of exerting a URL over the modem
connection to access the Proxy-Server. Theoretically, one could
exert a URL of a WEB site other than the Proxy-Server, but the
result would be an unusable connection, as the small hand-held unit
would not be able to handle the sophisticated data provided to be
downloaded unless it were such as e-mail or other simple data.
Connection to the Proxy-Server provides the Proxy-Server with
information as to the KW and the KW's equipment. These operations
proceed in a manner well known in the art for such log-on and
security transactions. Once access is extended to the KW, an
interface is provided for the KW to browse in a manner very similar
to well-known WEB interfaces. That is, the KW's display (61)
provides an entry field for a URL which is asserted by an enter key
or the like. There may also be an address book for often-visited
sites, as is common with more powerful machines.
Similarly, there are no strict requirements for the location of
Proxy-Server 49 or of accessible data sources or home stations in
embodiments of the present invention. No restrictions are placed on
such locations beyond restrictions on servers/nodes in general. In
one embodiment, a corporation with multiple and perhaps
international locations may have a local area network with one or
more Proxy-Servers, and employees, particularly those employees
whose job functions require travel, are provided with hand-held
digital assistants according to an embodiment of the present
invention. Multiple functions are then provided over Internet
connection in Internet protocol, far beyond what could otherwise be
provided with small and inexpensive units; and battery life for
these units (device 47) would be far beyond what would otherwise be
expected. Furthermore, a company could reduce or streamline a force
of KW's to a smaller number of mobile KW's with enhanced portable
devices such as device 47.
It will be apparent to one with skill in the art that the
device-proxy method such as the one described above could be
applied to a wide range of communication center architectures and
network operating systems without departing from the spirit and
scope of the present invention. A KW operating a device such as
device 47 may operate while traveling to or from client locations
as well as on-site at a client location. Types of devices used to
communicate with proxy server 49 may vary without departing from
the spirit and scope of the present invention. For example, PDAs,
small notebook computers, some cellular telephones, CE type
machines; all may be adapted for a proxy relationship.
Extended Management Control
According to another embodiment of the present invention an
enhanced method and system is provided for enabling full and
unobstructed access to contact center services and data for remote
knowledge workers, including provision of full state and
interaction management capabilities to the center managing the
knowledge workers. The method and apparatus of the present
invention is described in enabling detail below.
FIG. 3 is an architectural overview of a state and interaction
management system implemented from a contact center 300 according
to an embodiment of the present invention. Contact Center 300 can
be employed in any mix of communication environment. For example,
in a dually-capable COST/DNT multimedia environment, in a COST only
environment, or in a DNT only environment. In the present example,
a COST environment is illustrated. Likewise, one with skill in the
art will recognize that there may be more and different types of
known communication center equipment present and cooperative with
the system of the invention other than what is illustrated in this
example without departing from the spirit and scope of the present
invention.
Center 300 utilizes a central office telephony switch 316, which in
this case, is a private branch exchange (PBX) switch. Switch 316
may also be an automated call distributor (ACD) or another known
type or manufacture of telephony switch. Switch 316 is a relatively
dumb switch, but is enhanced for intelligent routing and control by
a CTI processor 317 running an instance of CTI transaction server
(T-Server) software. CTI enhancement in this example is driven by
T-Server software, which is an application that controls switch 316
and provides the intelligent computerized rules and executable
routines for interaction management and state detection and
management. A typical CTI link 315 connects processor 317 to PBX
switch 316 in this example.
An agent workplace 319 is illustrated within the domain of center
300. Workplace 319 is adapted minimally in this example with an
agent desktop computer 320 and an agent telephone 321. It will be
apparent to one with skill in the art that there will, in actual
practice, be typically many agent stations provided and adapted for
normal communication center routine business and communication. The
inventor illustrates only one station and deems the illustration
sufficient for the purpose of teaching the features of the present
invention in an enabling way.
In this case, agent telephone 321 is a COST telephone connected to
PBX switch 316 by standard internal telephony wiring. Agent desktop
320 is connected to a communication center LAN illustrated by a LAN
network 318 labeled T-Lib (for transaction library). A transaction
library contains all of the business and routing rules applied to
normal center interaction and operation. It may be assumed in this
example, that other equipment (not shown) is connected to LAN 318
such as other agent stations, a customer information system, a
product history database, and many other equipment types both
client-oriented and service-oriented.
An agent illustrated herein as agent 322 uses telephone 321 and
desktop computer 320 for the purpose of handling routine
interactions such as purchase orders, order status reports,
internal logging and reporting, and other tasks. In one embodiment,
telephone 321 may be an IP-capable telephone and also may have a
sound connection to desktop computer 320.
A COST telephony network 303 is illustrated in this example as a
preferred telephony network bridging customers to center 300 using
COST technology. Network 303 is a public telephony switch notably
most local to center 300. Switch 323 is the last routing point in
network 303 before making connection to switch 316 in a preferred
embodiment. In one embodiment, switch 323 is CTI-enabled similarly
to switch 316 within center 300 and communication center routines
can be executed at switch 323 over a separate network connecting
the CTI processors associated with both switches 316 and 323.
A customer 301 and a customer 302 are illustrated in association
with telephone network 303, which is a public switched telephone
network (PSTN) in this example. Customer 302 is illustrated as
placing a call to center 300 through switch 323 and switch 316. In
normal practice, the call of customer 302 will be internally routed
using CTI intelligence to an agent or automated interface within
center 300. In this case agent 322 receives the call on telephone
321. Desktop 320 will display any pertinent customer information
obtained from pre-interaction with customer 302 or from data
sources internal to center 300, or both.
A knowledge worker workplace 310 is illustrated in this example and
is associated with communication center 300 by a network link 314
adapted for ISCC protocols. ISCC is an acronym for the well-known
International Symposium on Computers and Communications.
ISCC-developed protocols may be assumed to be practiced over
network line 314 including a Flexible Interconnecting Protocol
(FLIP).
It may be assumed then, in this example, that KW workplace 310 is
located remotely from center 300 and outside of the physical domain
of center 300. Workplace 310 may be associated with other KW
workplaces in a remote contact center. In another embodiment,
workplace 310 may be a home-based workplace. In still another
embodiment, workplace 310 may be in a state of mobility such as in
a vehicle or at a remote customer worksite. KW workplace 310 has a
desktop computer 311 (or equivalent) and a KW telephone 312. A
knowledge worker (KW) 313 receives calls from PSTN 303 that are
directly placed from customers such as from customer 301, or calls
that are received to and then redirected from center 300.
As described above, KW workplace 310 is not physically part of
center 300 in terms of residing within a same building or physical
structure. Rather, worker 313 is operating from a remote location.
A major difference between the architecture of agent 322 and
knowledge worker 313 is that worker 313 has no CTI link between a
local switch and center 300. In this example, a local switch 304 is
illustrated and represents a local network switch (PSTN) presumably
closest to KW 313. In practice however, if workplace 310 is mobile,
such as working while traveling, there may not be a specific
permanent local switch from whence calls arrive to KW 313.
It will be recognized by one with skill in the art that in the
mobile sense, even in a wireless and semi-permanent networked
environment, the fixtures illustrated within workplace 310 may vary
widely. For example, telephone 312 may be a cellular telephone with
Internet capability and desktop 311 may be a PDA or a laptop. In a
fixed but remote location such as a remote knowledge worker contact
center, individual knowledge workers may still be highly mobile but
connected for communication to a LAN inside the center using a
variety of communication devices.
To facilitate connection from center 300 to knowledge worker
workspace 310, a programmable T-server/Processor 305 is provided
and distributed on a data packet network (DPN) such as, for
example, the well-known Internet network. If workplace 310 is part
of a permanent contact center operating remotely from center 300,
then switch 304 and processor 305 may be part of the equipment
maintained in the contact center. However, for knowledge workers
that are home agents or highly mobile, then switch 304 and
processor 305 are network level systems, switch 304 in the PSTN and
processor 305 in a private or public DPN.
The fact that there is no CTI link to center 300 means that under
normal circumstance, the activities of KW 313 in workplace 310
cannot be managed. The system of the invention is enabled by a
software platform known to the inventor as a Knowledge Worker
Platform (KWP) that functions in cooperation with hosting
equipment, namely processor 305, to alleviate the requirement for a
hardwired CTI link or other complicated connection methods, system
dependant CPE, or complex client software applications. KWP is a
proxy agent that receives KW status information (e.g. ready or not
ready) from a KW device such as from desktop 311 and sets the
information within CC environment at center 300. Status reporting
is used for determining KW availability for routing determination.
KWP also supplies the KW device with call-related information (e.g.
customer/product information) when an event is routed.
Workplace 310 is connected to processor 305, running an instance of
programmable T-server, by a network link 308. In this case,
processor 305 is accessible from desktop computer 311. In this
particular embodiment, desktop 311 and telephone 312 are permanent
fixtures and workplace 310 is part of an established physical
center. In this case, link 308 may be a LAN network providing
connectivity to other KW stations. Similarly, telephone 312 would
be just one of many connected to switch 304 by internal telephone
wiring. In this case, telephone 312 is also connected to desktop
311 by a cable so that desktop 311 may monitor call activity on
telephone 312. It will be appreciated that there are many other
possible architectural scenarios both fixed and mobile using
wireless technologies.
Desktop computer 311 has an instance of agent desktop (AD)
application installed thereon similar to a traditional application
expected for a traditional in-house desktop like desktop 320 manned
by agent 322 within center 300. However, the program on desktop 311
is modified to interact with KWP running on processor 305. KWP
(processor 305) and AD (KW desktop 311) exchange information
including Transaction Library data (T-Lib), Knowledge Worker
Protocol (KW Protocol), and Interaction Preview Data Protocol
(IPDP). Data links 307 and 309 are logical only and all data shared
between processor 305 and desktop 311 may travel over a single
physical or wireless data connection.
The AD application running on desktop 311 may be adapted to run on
virtually any network-capable device such as a cellular telephone
with display, an IP telephone, a PDA, a paging device, and so on.
The only modifications required for AD at workplace 310 are the
application program interfaces required to work with data that is
not in standard CTI format. In a preferred embodiment, KWP uses
Extensible Markup Language (XML)-based protocol for device
independent presentation and Extensible Style sheet Language
Transformation (XSLT) scripts for transforming XML source data to,
for example, HTML data or other data formats to accommodate
device-dependent data presentation requirements. Basically XSLT is
an XML processing language known in the art.
It is important to note herein that the models for KWP and AD are
the standard T-Server and agent desktop models. Appropriate
extensions are made to KWP and AD to enhance capability for dealing
with KW protocol and added T-Lib entities. For example, the model
for a knowledge worker is an extension of the model for a standard
agent. Therefore, attributes of the KW model do not exist in the
standard agent model. These attributes or object entities are added
to the standard T-Lib for KW use. The extended attributes define
the separation of remote KW characteristics and function
constraints from those of a regular CTI agent.
In practice, CTI telephony capability is extended to KW 313 by way
of link 314, 308, and the adapted applications KWP and AD. Switch
304 remains a dumb switch having no CTI control. For example,
assume customer 301 has a direct number to telephone 312 and places
a call to KW 313. The call request is routed through switch 323 to
switch 304 where notification of the call exemplifies a ringing
event at telephone 312. At this point, center 300 has no indication
or idea that KW 13 has a call-event ringing notification. However,
when agent 313 takes the call, AD software on desktop 311 detects
the activity and sends pertinent state data to KWP in processor
305, which in turn delivers the information to premise server
317.
Once server 317 has the information, other calls destined to
telephone 312 can be managed and queued according to KWP reporting
data. During interaction with the caller on telephone 312, KW 313
can use desktop 311 to obtain additional call and customer data,
product data, history data and so on from center resources.
Likewise, KW 313 may use terminal 311 to perform a call-related
action such as hold, transfer, terminate, and other like commands.
The command path in a preferred embodiment can be executed from
server 317 and direct to a CTI-processor running an instance of
T-Server (command path not shown) that intelligently enables switch
323 to terminate, interact or otherwise treat the event accordingly
at switch 323. An advantage is that management information is
available from the time of call receipt. If a queue is used, the
information may be used for queue management purposes so that the
center can tell whether or not a particular knowledge worker is not
available. The center can then route calls destined to KW 313 based
on availability.
In one embodiment, customer 302 places a call to KW 313 the event
routed through switch 323, and switch 316. By identifying the DN as
that of KW 313 (telephone 312) CTI messaging takes place between
switch 316 and the Premise T-server application on processor 317.
Server 317 then communicates through ISCC link 314 to the
Programmable T-Server application on processor 305 enhanced as KWP.
KWP messages with AD at desktop 310 to determine availability of DN
(telephone 312). AD checks telephone activity by link 306 and if
available responds along the reverse chain of links. Assuming
availability then switch 323 can seamlessly re-direct the event to
switch 304 by command from processor 317 and cause a ringing event
at telephone 312. This assumes that processor 317 is connected to a
like processor at switch 323. Otherwise, the call can be rerouted
from switch 316 through switch 323 to switch 304. Link 306 is
virtual in the sense that telephone activity at telephone 312 can
instead be monitored from switch 323 if it is CTI-enabled and has a
link to processor 317.
Outbound calls, inbound calls, and KW to KW remote calls can be
monitored and reported in terms of state activity and availability.
Assume, for example, that KW 313 places an outbound call from
telephone 312 destined for telephone 321 in agent workplace 319. AD
running on desktop 311 detects the outbound DN and uploads
pertinent data to processor 305 whereupon KWP sends appropriate
request for availability to Premise T-Server 317 controlling switch
316. Premise T-server 317 has information pertinent to the activity
state and availability of agent 322 in his workplace 319 by way of
LAN connection 318. Returned data follows the reverse chain and may
show up on desktop 311 before the ringing event has expired. A
wealth of information can be propagated between KW 313 and center
300.
Data about callers and contact center service tools and full
database access is made available to KW 313 on desktop 311 using
KWP and AD applications. If there is no monitoring capability
between the device that KW 313 receives an event on and the
computing platform of KW 313, then KW 313 may have to manipulate AD
on the computing platform in order to access center 300 for data
pertinent to the event. In other embodiments the computing platform
and the device used to receive events are one in the same such as a
network-capable cellular telephone for example.
KW 313 can register any number of DNs from AD on desktop 311 to
receive events when he or she is leaving workplace 310 and will be
away for a period. In the case of a short distance, a wireless
peripheral can be used to access center data through desktop 311
and a wireless telephone can be set-up to receive the events. There
are many equipment variations that are possible.
The nature of the connection between KWP and a KW device can be
configured according to a number of criteria and supported
platforms. For example, a one-way connection can be utilized for
practicing only KW status notification to center 300. A two-way
connection can be practiced for call-related data propagation. In
addition to dial-up techniques to facilitate the connection between
KWP and a KW device, wireless and Internet Protocol (IP)
connections can be implemented. It is also possible to practice the
invention with a simple PSTN connection.
KWP architecture supports any existing media and platform. More
specifically, KWP supports a traditional desktop with a data link
(illustrated in this example), wireless linking for PDAs and
wireless browser applications. KWP also supports conventional voice
devices including but not limited to analog telephone, conventional
IVR, and VoiceXML based IVR. Messaging protocols such as Simple
Messaging System (SMS), Instant Messaging (IM), email. Internet
markup languages such as traditional HTML-based languages are
supported along with more recently introduced Wireless Application
Protocol (WAP) and Wireless Markup Language (WML). More detail
regarding the software platform of the invention and how it
functions in telephony scenarios is presented below.
FIG. 4 is a block diagram illustrating system connection hierarchy
according to an embodiment of the invention. In this simple
example, KWP402 resides between the communication center
environment (401) and the remote KW or KWs. Therefore, KWP 402 is a
proxy-serving platform that is integrated as an extension of the
CTI telephony platform generally described as the T-Server
platform. In this example, CC Environment 401 is analogous to the
capabilities of center 300 described with reference to FIG. 3
including any extension of those capabilities into the PSTN network
by way of separate data network connections and CTI processor
distribution to network level components.
KWP 402 is analogous to KWP running on processor 303 described with
reference to FIG. 3. IP network 404 and PSTN network 403 illustrate
exemplary communication networks used in communication. Other
networks may also be substituted therfor or used in conjunction
therewith. A plurality of KW devices is illustrated as examples of
varying types of devices that may be used by a KW to practice the
invention. A standard analog telephone 405a can be used in a simple
embodiment to communicate with KWP through PSTN 403. IVR-based
technology is used in this case to provide the KW with call and
center-related data as well as for receiving routed events. A
cellular telephone 405b is illustrated and can be adapted to
communicate with KWP 402 through a COST connection or through a DNT
connection. WAP and WML are supported so that XML-based data from
CC environment 401 can be displayed on device 405b.
It is noted herein that AD, described with reference to FIG. 3,
normally requires approximately 30 megabytes of disk space in a
robust version for desktops and the like. Therefore, an AD-Lite
application would be downloaded to device 405b according to storage
availability. In another embodiment, AD may be combined with KWP at
server side wherein AD is still personalized to the particular KW
authorized to access it and operate it from device 405b.
A PC 405c is illustrated in this example and is analogous to
desktop 311 described with reference to FIG. 3. A PDA 405d is
illustrated in this example as a possible KW device that
communicates to KWP through IP network 404, or can also be operated
with a wireless connection through PC 405c as a host.
FIGS. 5 through 8 are block diagrams illustrating call control use
cases according to an embodiment of the present invention.
Referring now to FIG. 5, the basic advantage of KWP in that KW
agent 501 can accept inbound calls from customers (502) wherein
availability status, skill level, and other criteria can be
provided to the communication center environment for the purpose of
routing call 502. If the DN of KW 501 is not integrated with a KW
computing platform, then KW 501 can still enter input from the
KWP-connected computing platform when on call using an unregistered
DN to retrieve data. At this point the communication center can
track the activities and results based on KW data input. In another
embodiment, the DN of the KWs receiving telephone can be set in the
CC environment wherein a network level switch enhanced by CTI
software can monitor state, determine best routing, and initiate
data transfer of call-related and center-related data to the KW
without first party input.
Referring now to FIG. 6, KW 601 can initiate an outbound call
(602). As an extension to traditional outbound dialing, a
preview-dialing mode 603 is supported which includes preview
dialing notification caused by outbound contact (605) and a
preview-dialing mode supported by Internet suite (605) for IP
mode.
Referring now to FIG. 7, a KW (701) can place or receive internal
calls (702) from other knowledge workers. This includes an internal
call without notification (703), an internal call with notification
(707). An internal call with notification includes an option (708)
for preview answer of the internal call associated with a manual
agent reservation. There are several extended options including an
external call (709) via RP queue performed by an external T-Server,
an internal call (706) from a center agent performed by the
external T-Server, and an internal call (704) from another KW.
Option 704 can be extended to an option of internal call (710) from
a KW performed by an external programmable T-Server, or an option
of internal call (705) from a KW performed by a local programmable
T-Server.
Referring now to FIG. 8, KW 801 can initiate more complicated
interactions such as a two-step transfer (802), a two-step
conference (803), and a hold and retrieve (804).
FIG. 9 is a block diagram illustrating components of the Knowledge
Worker software and integration thereof to a communication center
framework. The KWP 901 of the present invention includes a server
application 904, which is analogous to programmable T-Server and
KWP software running on processor 305 described with reference to
FIG. 3 above. A KW desktop or "client" application 903 is also part
of KWP 901. KW desktop 903 is analogous to AD running on desktop
311 described with reference to FIG. 3.
KWP communicates with a communication center (CC) Platform 902 over
a data link (908, 907) that supports ISCC protocol. Link (908, 907)
is separated in terms of element number to show communication of
two separate components in this example. However, the physical link
is analogous to link 314 described with reference to FIG. 1.
CC platform 902 includes a configuration server 905 and standard
premise T-Server 906. Configuration server 905 is a software
implement that is used to configure and update KWP/programmable
T-server 904. In turn, KWP/T-Server programs KW desktop 903 if
required. As was described further above, KWP 901 is an extension
of CC framework. For example, T-server 906 serves as a basic model
whereas KWP/T-Server is extended in functionality by additional
attributes and capabilities.
Existing T-Library (T-Lib) protocol is used to build additional KW
messaging between KWP/T-Server and client the application 903.
Standard agent desktop applications are extended to provide KW
functionality.
FIG. 10 is a block diagram illustrating components of the knowledge
worker platform 901 of FIG. 9. As described with reference to FIG.
9 above, KWP 901 comprises a KW desktop application 903 and a KW
T-Server application 904. KW desktop application 903 comprises an
agent desktop application known to the inventor as Contact
Navigator given the element number 1009. Contact Navigator 1009
utilizes a Transaction Library or T-Library 1008, which contains
all of the required business and routing rules and object entities
needed to build useful communication between two physically
disparate systems namely, the CC platform and the KWP. By
themselves, navigator 1009 and library 1008 are identical to the
desktop application contained within the physical contact center
domain analogous to AD running on agent desktop 320 in center 300
described with reference to FIG. 3 above.
In this example, desktop 903 is enhanced with KW extension software
1010. KW extension 1010 contains all of the attributes that
facilitate the added capabilities of a KW desktop over a standard
model desktop. T-Lib 1011 is thus enhanced with the appropriate
components defined by the extension. It is noted herein that since
KW desktop 903 is based on the standard desktop model (contact
navigator) added capability can be remotely programmed thereto
using the configuration server described with reference to the CC
platform of FIG. 9. The appropriate components are downloaded to KW
extension 1010 for KW use.
KW desktop 903 has connection with KW T-Server 904 as described
further above in this specification. KW T-Server 904 is partitioned
into two parts, a T-Server common part 1001 and a KW specific part
1002. KW T-Server 904 is also enhanced with ISCC communication
capability via ISCC protocol 1003 for the purpose of economic
communication with the contact-center platform.
One main goal of the invention is to maintain separation of KW
specific part of T-Server functionality from the standard
functionality of T-Server framework components at the host contact
center. Such separation allows independent development and support
for KWP 901 over contact center framework. Further, separation
enables seamless integration of KWP with a variety of host
customer-relation-management (CRM)-vendors.
KW protocol is provided instead of traditional CTI protocol. KW
protocol, shown exchanged over logical link 1006 between the
desktop and the T-Server provides CTI like messaging capability.
This means that any KW desktop that registers a DN with KW T-Server
904 establishes telephony switch functionality at the contact
center for servicing those registered DNs. KW protocol carries CTI
like messages regarding real-time status of any registered DNs from
KW desktop to KW T-Server. Various call-control messages are
supported like TmakeCall, TanswerCall, TreleaseCall, THoldCall, and
so on. These messages are treated as CTI messages that inform KW
T-Server 904 of status of a particular interaction.
The structure of messages in KWP is presented in FIG. 24. The KWP
message is encoded in a KVList data type that enables future
extension of KWP without breaking compatibility with older
applications.
KVList Structure
The following code exemplifies the structure of a KVList:
TABLE-US-00001 typedef enum { KVTypeString, KVTypeInt,
KVTypeBinary, KVTypeList, KVTypeIncorrect = -1/* used for error
indication only */ } TKVType; struct_kv_pair { TKVType type; char
*key; int length; union { char *_string_value; int_int_value;
unsigned char *_binary_value; struct kv_list *_list_value; }_value;
#define string_value _value._string_value #define int_value

struct_kv_list { struct_kv_ pair *list; struct_kv_pair *current;
struct_kv_pair *tail; }; typedef_ struct kv_list TKVList;
TEvent Structure
The following code exemplifies the structure of a transaction event
(Tevent):
TABLE-US-00002 typedef struct { enum TMessageType Event; TServer
Server; int ReferenceID, char *HomeLocation; char *CustomerID;
TConnectionID ConnID; TConnectionID PreviousConnID; TCallID CallID;

Another protocol provided for use in practice of the present
invention is known as Preview-Interaction-Protocol (PIP) to the
inventor. Preview interaction protocol is illustrated as being
exchanged between KW T-Server 904 and KW desktop 901 over logical
link 1004. PIP provides an ability for a KW to preview incoming
interactions before actually receiving them. In this way, a KW has
the capability of accepting or rejecting an incoming interaction
based on attached data such as user data attached with an incoming
telephone call. This capability also allows the contact center
platform to correctly process external call-control routines like
external call, external transfer, external conference, and so on.
All preview interaction messaging takes place between KW desktop
903 and KW T-Server 904.
T-Library functions as a messaging transport layer in the software
communication scheme. In other words, particular T-Lib messages are
used to carry KW protocol and PIP messages.
FIG. 11 is a configuration model 1100 for knowledge worker state
information according to an embodiment of the present invention.
Configuration-Management-Entities (CME) are configured into the
system for active state and call control. CME configuration model
1100 is a typical CME configuration routine for configuring remote
knowledge workers to practice the present invention. First a KW is
configured with CfgPerson 1101. Secondly, the place or places of
operation are configured with CfgPlace 1102. The relationship
between person and place typically includes one place where a KW
will receive interactions. However in some embodiments a KW may be
live at one place and have automated services set up in another
place. Therefore, the relationship between person and place in this
CME model can be one to many.
Place 1102 has two basic attributes that must be configured. These
are agent login (CfgAgentLogin) 1103 and DN (CfgDn) 1104. Agent
login includes any pre-designed procedure deemed appropriate for a
KW to login to the system of the invention. In some cases login may
not be required in terms of passwords and so on. Simply opening a
connection between the KW computing platform and the KW T-Server
may be sufficient for login purposes. In some embodiments, KW
platforms associated with automated systems may remain connected
and, therefore logged in 24/7. In other cases, automated connection
establishment and login may be pre-programmed so that the KW
platform will login whether the agent is actually there or not.
CfgDn 1104 is used to register one or more KW DNs with the contact
center environment, typically a CTI telephony switch. A KW may
configure more than one DN with attached data as to what types of
interactions should be routed to which DN. A DN may include one or
more telephone numbers, cell phone numbers, an e-mail address, a
virtual number for an automated system, an IP address and still
other location identifications. One to many relationships between
place 1102 and agent login 1103 are possible. Similarly, one to
many relationships between agent login 1103 and CfgDn 1104 are
possible.
CfgSwitch 1106 configures the acting telephony switch or switches
practicing the present invention. This process uses a special KW
gateway. CFGKWGateway enables the switch to differentiate KW
telephony traffic from regular contact-center and other normal
traffic. Switches with or without CTI links are configured if they
are involved in KW interaction routing. CfgApplication 1107 is used
to configure KWP software at the remote location. This
configuration process includes configuring KW T-Server and KW
desktop software. CME provides data sync methods for data
synchronization, data transformation between customer main and
central storage facilities and data transfer between directories by
LDAP or preferably through XML and XSLT import/export
mechanisms.
FIG. 12 is a data model for presenting an active knowledge worker
state. The model of this example presents the various agent states
that are implemented by KW T-Server 904 described with reference to
FIG. 10 above. The basic reportable states are Agent Login, Agent
Logout, Agent Ready, and Agent Not Ready. This model is the basic
agent model for standard CTI-T-Server implementation as would be
the case inside contact center 300 described with reference to FIG.
3. Hence the term agent can be replaced with the more appropriate
term knowledge worker for remote implementation. The arrows
represent all possible associations in the model. One with skill in
the art will recognize that this is a basic example and that other
reportable knowledge worker states may also be represented in this
model. Similarly, this model may be applied to different types of
interaction media including telephone interaction without departing
from the spirit and scope of the invention.
FIG. 13 is a process flow diagram illustrating the sequence of a
successful internal call. At step 1300 a KW initiates an internal
call to another KW. This action can occur from a KW telephone or
from a KW computing platform analogous to telephone 312 and desktop
311 of station 310 described with reference to FIG. 3. At step
1301, a KW T-Server analogous to processor 305 described with
reference to FIG. 3 receives notification of the initiated call and
sends a preview interaction message (PIM) to the destination KW.
The PIM is forwarded before the call is dialed and gives the second
KW a chance to decide whether or not he will accept the call based
on the PIM data.
At step 1302, KW-2 receives and, in this case accepts the PIM from
the KW T-Server. A dotted return arrow illustrates an acceptance
response forwarded back to the T-Server. At step 1303, the T-Server
dials the DN specified in the call initiation event. A notification
of a dialing event (broken return arrow labeled Event Dialing)
displays on the caller's computer platform or is activated on the
caller's telephone with respect to KW of step 1300. There are many
indication possibilities for a dialing event. A ringing event is
also established by the T-Server at the computer platform or
telephone of KW-2 as illustrated by the broken arrow labeled
Ringing. At this particular moment it happens that KW-2 is on a
current call. A pre-defined time period may be established for the
ringing event so that KW-2 may, during that time, terminate the
previous call and pick up.
At step 1304, KW-2 picks up the call. Detecting the pick up at step
1305, the KW T-Server establishes the connection between the KW of
step 1300 and KW-2 of step 1304 as indicated by broken arrows. It
will be apparent to one with skill in the art that there may be
variations in this process for a successful internal call between 2
KWs without departing from the spirit and scope of the invention.
Variations in the flow are dependant on actual events. For example,
in the case that KW-2 could not terminate the previous call to pick
up the initiated event before a sever timeout has occurred, a
notification of not ready could be returned to the initiating KW.
Similarly, KW-2 could opt to reject the call before it is made by
rejection the PIM request.
FIG. 14 is a process flow diagram illustrating a variation of the
sequence of FIG. 13 with a forced answer. In this example, steps
1400-1403 are identical to steps 1300-1303 described with reference
to FIG. 13 above. Therefore, the same description given in the
example above applies to steps 1400-1403 of this example as
well.
At step 1404, there is a forced server time out indicating a forced
answer mode. At step 1405, a ringing event is established at the
station of KW-2 audible over telephone or audible and perhaps
visible on the computing platform of KW-2. At step 1406 then, KW
T-Server establishes connection for the dialed event. It is noted
herein that event connection first connects the initiating party
and then the receiving party as indicated by broken arrows A and
B.
FIG. 15 is a process flow diagram illustrating the sequence of a
failed internal call. At step 1500 a KW initiates a call to another
KW as described with reference to the previous 2 examples. At step
1501, the KW T-Server sends a PIM request to the second KW (KW-2).
However, upon reviewing the request, KW-2 decides not to accept the
call and rejects the PIM in step 1502 as illustrated by a broken
return arrow. The result of this action is that in step 1503, the
KW T-Server returns an error message or notification to the
initiating KW. It is noted herein that notification messages can
take the form of a wide variety of media such as Voice over
Internet Protocol (VoIP), IVR response, e-mail response, and so on
dependant upon media type and equipment.
FIG. 16 is a process flow diagram illustrating the sequence of an
internal call with a forced timeout before PIM decision according
to an embodiment of the invention. Steps 1600 and 1601 are
identical to the first 2 steps of the previous examples. However,
at step 1602 a forced server timeout occurs before KW-2 responds to
the PIM request sent in step 1601.
At step 1603 the KW T-Server sends a timeout error notice to the
initiating KW. In the meantime, the PIM request sent to KW-2 is
still alive and pending. At step 1604 after the timeout occurs,
KW-2 receives the PIM request and determines whether to accept or
reject the call. If in step 1604 KW-2 accepts the request, then at
step 1606 KW T-Server dials the DN number and subsequent steps for
dial notification, ringing event notification and connection
establishment occur as with a successful internal call. However, if
KW-2 rejects the call event at step 1604, then at step 1605 KW
T-Server sends an error notification back to the initiating KW as
indicated by the broken return arrow.
FIG. 17 is a process flow diagram illustrating the sequence of a
successful external call according to an embodiment of the
invention. At step 1700 a center agent initiates a call to a remote
KW. Initiation of the call can take place from the agent telephone
or from the agent desktop analogous to telephone 321 and desktop
320 in workplace 319 of center 300 described with reference to FIG.
3. At step 1701 the desktop T Server opens a connection to a first
local router or router 1. It is noted herein that the T-server
implement may be in the agent desktop itself or it may be in a
premise T Server processor accessible to the agent.
At step 1702 the first router local to the agent sends a request to
a second router local to the KW to get an access number or DN. At
step 1703 the second router forwards the request to the KW T-Server
hosting the agent. It is assumed in this example that the KW in
question is logged in. Otherwise, an error message (KW not
available) would be returned to the initiating agent.
At step 1704 the KW T-Server sends a PIM to the KW having the
requested access number or DN. The KW is now aware of the impending
incoming call and can decide whether to accept or reject the call.
In this case, the KW that will receive the call accepts the PIM
request as indicated by the associated block below block 1704. At
step 1705 KW T-Server requests call data from the second router. In
the meantime, at step 1706 the second router gives the access
number to the first router local to the agent.
At step 1707 the first router sends a call request to the premise
T-Server. At step 1708 the premise T-Server extends the call
request to the premise switch. At step 1709 the switch dials the
associated DN and notifies the premise T Server in the first phase
of dialing. At step 1710 the premise T-Server notifies the first
router of the DN in phase 2 of dialing. At step 1711 the first
router notifies the agent desktop of the dialing (phase 3). This
manifestation may occur on the agent telephone, desktop or
both.
At step 1712 the KW T-Server establishes a ringing event at the
second router local to the KW in a first phase of ring
notification. At step 1713 the second router establishes the
ringing event at the KW station, for example, on the telephone or
desktop or both. At step 1714 the connection is established between
router 1 and router 2. At step 1715, the connection is extended
from router 1 to the calling agent. It is assumed in this example
that the connection is a COST connection, however DNT interactions
are similarly routed according to CTI rules.
It will be apparent to one with skill in the art that the steps
described in this example may vary in number and order without
departing from the spirit and scope of the present invention. For
example, it may be that there are more than 2 routers involved in
the connection path of the call. Similarly, server timeouts, agent
availability, queuing requirements, and so on can change the nature
and order of the described steps. The inventor intends that the
presented example illustrate just one example of an external
incoming call sourced from a center agent and destined to a remote
knowledge worker according to a preferred embodiment.
FIG. 18 is a process flow diagram of a failed external call
according to an embodiment of the present invention. Steps 1800
through 1804 are identical to steps 1700 through 1704 described
with reference to FIG. 17 above for a successful external call from
a center agent to a remote KW.
At step 1805 however, the KW decides not to accept the pending call
and return a rejection response. At step 1806 the KW T-Server sends
a data request to R-2 for call data. At step 1807 R-2 sends an
error message to KW T-Server because of absence of call data due to
KW rejection of PIM request. At step 1808 R-2 returns an error
message to R-1 local to the agent regarding the earlier request for
access number at step 1802. At step 1809 R-1 sends an error message
to the agent station as indicated by a broken arrow. The error
message may be that at this time KW John in not available due to
current load or duties. The fact that KW decided not to take the
incoming call from the agent can be expressed in a variety of
syntax. Perhaps the agent could elect to receive a call back from
the KW at a more advantageous time or perhaps the agent can be
prompted to place the call again at a latter time period.
It will be apparent to one with skill in the art that remote call
control is possible and practical using the method of the present
invention without a functioning CTI link provided between the
center and the local switch closest to the KW center or other
remote KWs. Incoming calls can be routed to any remote KW with a
connection to the KW T-Server according to availability, skill
level, and so on. In a preferred embodiment intelligent routing of
events to remote KWs can be made at the premise of the
communication center or at network level. In the case of network
level routing, a network T Server must be provided to enhance the
involved network level switch or switches.
If all KWs are, for some reason, unavailable at the time of a call
attempt, then IVR functionality can be utilized to prompt the
caller to leave a number for a return call. In this embodiment,
premise T-Server function enables outbound dialing and connection
when it is determined that a KW becomes available to take calls. In
one embodiment ISCC protocol enables a center agent engaged in a
call to transfer the connection to a remote KW with data attached
to the event. XML-based data and XSLT transformation capability
renders the attached data into the desired format for dissemination
at the KWs end device whether it is a voice only device or a
display-capable/voice capable device, or even a display only
device.
In another embodiment, the service-provider infrastructure (center)
can partially monitor independent interactions through network
signaling such as D-channel pinging, OSIG, or call progress
detection mechanisms.
Voice-Based Management
According to yet another aspect of the present invention, a
voice-based management system is provided to extend functionality
in management of remote KWs in a communications-center environment.
The methods and apparatus of this invention in preferred
embodiments are described in enabling detail below.
FIG. 19 is an architectural overview of a state and interaction
management system enhanced with voice-management capabilities
according to an embodiment of the present invention. One goal of
the present invention is to provide a voice-based system for
enhancing KW state reporting capabilities and KW control from the
viewpoint of a communications center. The enhanced management and
reporting environment uses voice extensible markup language
technology (VXML), text-to-speech (TTS) and automatic speech
recognition (ASR) technologies.
This example is similar in some respects to the example described
with reference to FIG. 3, above except that voice-based management
capabilities are integrated with data management and transfer
capabilities across disparate networks in order to provide enhanced
cross-communication between a KW and communications center
applications resulting in better overall performance of the system
as a whole.
Referring now back to FIG. 19, some elements that are illustrated
herein were also introduced and described with reference to the
example of FIG. 3 above. Therefore, those elements, which have
already been introduced and described, retain their same element
numbers and shall not be reintroduced. Contact center 300 is
illustrated in this example in a much-simplified form than that
described with reference to FIG. 3 above. For example, some
agent-workplace components are not specifically illustrated in this
example for the purpose of more clearly describing the present
invention, but may be assumed to be present. PBX switch 316 is
illustrated in this example along with premise T-server 317 running
an instance of KWP (Knowledge Worker Platform) analogous to KWP
running on server 305 described with reference to FIG. 3 and also
illustrated in this example. All other communications systems that
are typical of state-of-art communications centers are represented
herein by a LAN arrow 401, the illustration of which is meant to
indicate a full and robust compliment of systems and components
required to enable a communications center. Hereinafter, the
element number 401 is used to indicate a communications center
environment analogous to CC environment 401 described with
reference to FIG. 4 above.
PBX 316, which is CTI-enhanced in this example, is reachable
through PSTN network 303 from a local PBX switch 323 via telephony
trunk(s). KW workplace 310 is analogous to workplace 310 described
with reference to FIG. 3. Only telephone 312 is illustrated in this
example as one communication component or fixture residing in
workplace 310. Telephony 312 may be an IP telephone or a
plain-old-telephone-service (POTS) connected telephone. KW 313 and
Computer 311 are omitted from this example for the sake of
simplifying illustration but are assumed to be present. The proxy
system previously described with reference to FIG. 3 including
T-server 305 running an instance of KWP is illustrated in this
example. As previously described, T-server 305 has connection to
center 300 through an ISCC compatible data link. KW protocol, IPDP,
and T-Lib protocols are available through T-server 305 and are
implemented as previously described with reference to FIG. 3.
In this example, a Wide-Area-Network (WAN) 1903 is illustrated as
part of the overall communications network. In a preferred
embodiment WAN 1903 is the well-known Internet network and may be
referred to as Internet 1903 in this specification. In other
embodiments WAN 1903 may be a private or corporate network
including an Intranet or Ethernet network. The inventor chooses the
Internet as a preferred embodiment in this example because of the
high public access characteristic. This is also the case with
respect to PSTN 303.
Internet 1903 has an Internet backbone 1900 extending there through
that represents all of the network lines, access points and
equipment that make up the Internet network as a whole. It is
clear, that in various types of applications, and in some other
cases, this may not be "The Internet", but a private or other
network's backbone. Therefore there are no geographic limitations
to the practice of the present invention. Contact center 300, also
termed a communication center, has connection to Internet 1903
through any of several known Internet access methods including DSL,
ISDN, dial-up or others. Internet connection capability between
center 300 and Internet 1903 is a 24.times.7 connection in
preferred embodiments of the present invention. In this example,
T-server 317 also serves (logically) as an intelligent router for
routing data from the Internet to appropriate destinations within
center 300. It will be appreciated however that a dedicated IP
router or server may be provided instead as a separate component
from T-server 317 and linked thereto for communication.
Internet 1903 has a Web server 1902 provided therein and
illustrated as having connection to Internet backbone 1900 for
communication. Web server 1902 is adapted to serve electronic
information pages (Web pages) and is, in a preferred embodiment,
hosted by a same entity that hosts center 300. Server 1902 can be
provided within the physical domain of center 300 without departing
from the spirit and scope of the present invention. Center 300 is a
dually-capable center, meaning that it may process both COST and
DNT communication events.
Web server 1902 has a VXML application 1901 which is adapted to
generate executable VXML scripts. Web server 1902 also has a KW Web
application 1908 adapted to communicate with a KWP application
provided to and executable from T-server 317 located within center
300. Application 1908 converts VXML data into data of a format
understood by CTI platform software and other center application
formats used within center 300 for routing, scheduling, data
aggregation, and other functions.
Web server 1902 is adapted to generate and execute VXML scripts.
Web server 1902 is accessible by voice-based mediums (telephone)
through a KW VXML gateway 1904 linked for communication to backbone
1900. VXML gateway 1904 contains TTS and ASR software for
performing various tasks related to voice recognition and voice
synthesizing from text (VXML) scripts. As a vocal portal, gateway
1904 is accessible through switch 323 in PSTN 303. For example, a
KW operating phone 312 can access Web server 1902 through an
appropriate link between phone 312 and gateway 1904.
Building a VXML implementation, at the lowest level, is based upon
generating one or more Web pages that contain VXML commands. These
web pages are executed by VXML gateway 1904. Gateway 1904 parses
VXML pages generated and served by server 1902. Based upon the
commands on a VXML page, the VXML gateway interfaces with or
includes an ASR engine and/or a TTS engine. The VXML gateway
contains an interpreter application that controls telephony, ASR,
and TTS resources. In one embodiment of the invention gateway 1904
including the TTS, interpreter, and ASR components mentioned is
contained within one server, namely server 1902. However, the
inventor logically illustrates separate components in this example
in order to more clearly describe them.
In one embodiment, PBX 323 is also accessible to a mobile KW
illustrated herein as Mobile KW 1906 operating, in this case, a
cellular telephone device 1907. Typical access is wireless and
achieved through connection to a wireless data network illustrated
herein as network 1905 using a wireless network gateway (GW)
illustrated herein as GW 1910. In one embodiment there may be a
direct connection between GW 1910 and VXML gateway 1904. KW 1906
may, in one embodiment be the same KW that is stationed at
workplace 310, the KW having left workplace 310 temporarily and
currently operating from device 1907 in a completely mobile
environment such as out in the field.
In practice of the invention, a VXML-enhanced state of reporting
and management is enabled wherein a KW may use any simple telephone
to report state of readiness vocally through gateway 1904. Gateway
1904 recognizes the voice renderings of the KW using ASR technology
and converts the speech to VXML commands for processing by Web
server 1902 running VXML scripting software 1901 and Web
application 1908.
Server 1902 downloads the reported state information as XML-based
or, if so enhanced, CTI-based data to server 317 running an
instance of KWP. Server 317 then notifies the communication center
environment (401) including PBX 316 according to whatever the
reported state was including issuance of any related commands. For
example, KW 1906 may dial a pre-set telephone number (VXML gateway)
registered at switch 323 using phone 1907. The pre-set number
addresses VXML gateway 1904 to take the call. Based on a VXML
script, the KW when prompted says, for example, "ready on mobile"
meaning that he or she can now take service calls but only from the
mobile telephone used to dial in or another designated telephone
number that can be registered. If prompted, further state detail
may be reported such as ready from a certain begin time to a
certain stop time. Still more detail can be reported using phone
1907 in a same session such as availability only for a certain type
of call, or available only for teleconferencing on a specific
project, and so on. There are many configurable possibilities.
VXML scripts can have empty fields for accepting voice renderings
or DTMF inputs that fill those fields during voice interaction.
These fields may also be filled using touch-tone command methods.
VXML pages also have data executable commands and voice dialogs
that are played as synthesized voice media streams.
Because KW 1906 is mobile when he or she calls in to report state,
he or she may be considered by center 300 to be not available for
routing at his workplace if he or she has one. For example, if KW
1906 is the operator of workplace 310 it is now known after state
reporting to the center that he or she is not physically present at
the main workplace, hence calls requiring database access or other
requirements for accessing computer information may not be routed
to telephone 1907. However, because state has been reported, center
300 can now update KW workplace 310 through ISCC compatible network
314 and can access data there from and report it back to KW 1906 as
a voice synthesized media stream over telephone 1907 using TTS
technology. This can occur while the KW is talking on the telephone
by using call hold toggling methods.
For example, server 317 having received a "ready" state report from
KW 1906 may cause a call incoming to switch 316 to be re-routed to
the now-ready mobile operator 1906 on telephone 1907. Through IVR
interaction, the center determines before routing the call that
some information available from KW workplace 310 may have to be
presented during the interaction between the caller and KW 1906.
Server 317 can access the required data from KW workplace 310 if
authorized and workplace 310 is "online". Additionally, server 317
can also provide any call-related data that may have been solicited
from the caller during interaction at switch 316 before
re-directing the call.
Server 317 with the aid of KWP software uploads the extracted
information and the caller information to Web server 1902. Server
1902 then generates VXML script and dials VXML gateway 1904.
Gateway 1904 parses the VXML and generates a voice media stream
vocalizing the data and dials the telephone number of 1907 not
necessarily in the same order. The caller, if already connected,
can be put on hold while KW 1906 picks up the call from the center.
When KW 1906 answers, the voice stream containing the required
information is played and can be recorded at time of play, recorded
by note taking, or replayed using touchtone commands. When KW 1906
receives and records the data then he or she has the information
available to help the caller even though he or she cannot
physically access workplace data from station 310 or contact center
data from center 300 using telephone 1907.
The system of the invention is bi-directional as exemplified in the
scenario cited above, meaning that VXML scripts are directed both
ways in communication. A KW can report previous, present, or future
state information related to functions or duties using a simple
telephone. The center in turn can update the appropriate data
systems within the center including performing any switch
configurations and routing routine pre-sets. The center can also
update the KW workplace with any timely information that may be
required or related to the last report. The center can also make
vocal requests to the KW through telephone 1907 using outbound
dialing techniques through VXML gateway 1904. All data syncing
functionality between the KW workplace and the center can be
controlled through voice interaction alone. In fact, a KW may place
a simple telephone call to the center to cause his or her workplace
to boot up and be configured remotely for a planned work session.
There are many possibilities of integrating VXML into the
ISCC-based management system.
No appreciable modification of KWP software is required from the
version described with reference to U.S. patent application Ser.
No. 10/269,124 listed in the cross-reference section above and
included herein. XML and XSLT including VXML are already supported
by KWP software.
FIG. 20 is a block diagram illustrating system connection hierarchy
including voice-based enhancement according to an embodiment of the
invention. Communication center environment 401 represents center
platform systems and applications including CTI call control, call
control XML, Telera XML, and other languages that may be in use.
KWP 402 is a proxy between the external KW environment and the CC
environment. KWP configures the CC environment including CC switch
management based on state reporting from a KW.
Web server 1902 running VXML application 1901 and KW Web
application 1908 interacts with VXML gateway 1904 to receive audio
stage reports and to deliver audio streams to KWs during
interaction and telephony event processing. KWs may interact with
the system of the invention from any regular telephone, for example
from telephone 405a through PSTN 403 or through cellular telephone
405b through wireless network 1905. Voice interaction can also
occur from a computing platform like PC 405c or PDA 405d through IP
network 404.
The system of the invention, namely those components comprising
server 1902 and VXML gateway 1904, adds a simple vocal management
capability for center management of remote KWs that can be layered
over the software suite described with the ISCC-based system.
Essentially, the system of the present invention is a separate
component from the system described with reference to application
Ser. No. 10/269,124 except for integration with KWP and the CC
environment.
Referring now back to FIG. 19, there are at least two separate
communication paths in the main architecture for remote KW
management. One is the VXML-enabled path between switch 323 and
server 317 through server 1902 by way of backbone 1900. The other
is the ISCC data path from server 317 to server 305 and workplace
310 by way of ISCC link 314 and logical connection (307, 308, and
309). Applications within center 300 can communicate using VXML by
interacting with KWP in 317 and Web server 1902 to generate VXML
script, which is then interpreted and synthesized as audio media
streaming by gateway 1904 accessible to switch 323 and KW
telephones.
Referring now back to FIG. 20, Web application 1908 interfaces with
VXML application (Script) 1901 and translates the XML data to
protocols used by KWP (XML, XSLT) and KWP interfaces with the CC
environment (CTI, or other XML-based call control languages) as
well as other required data formats for storing and managing data
including data access formats.
Referring now back to FIG. 19, a human operator residing within
center 300 can use VXML spoken commands to configure or set
workplace 310 for performing certain tasks or for accepting certain
incoming events. This can be accomplished by out dialing through
switch 316 and switch 323 to gateway 1904. VMXL fields are filled
in as previously described through ASR and processed at Web server
1902. At this point update and configurations are made through ISCC
protocol network 314. For example, an administrator could call a
special number identified and registered to a particular workplace
310. Gateway 1904 interacts with the administrator to determine
which of a plurality of VXML dialogues it will use to propagate the
administrators intended purpose. It is important to note herein
that in one embodiment, ISCC network 314 and server 305 may be
Internet hosted.
FIG. 21 is a process flow diagram illustrating steps for
VXML-enabled remote-KW state reporting to a CC environment
according to an embodiment of the present invention. At step 2100,
a remote KW places a telephone call to the communications center
(CC) to report a state. At step 2100, the KW may use any telephone
or telephony voice device either from a mobile position or from a
fixed workplace.
At step 2101, a VXML gateway analogous to gateway 1904 described
with reference to FIG. 19 accepts the call waiting at the local
switch (323 FIG. 19). In this embodiment it is assumed that the
local switch is preprogrammed with the destination number used by
the KW so that the communication center switch (316) does not
actually receive the call. In another embodiment, the call actually
progresses first to the central switch of the communication center
adapted to recognize the special destination number. The call is
then re-routed back to switch 323 for interaction with the VXML
gateway. In the second embodiment, the communication center has
knowledge of the pending sate report and can also notify the VXML
server and the VXML gateway of the pending call and any additional
data for identifying, for example, which VXML script to serve and
execute, and so on.
At step 2102 the VXML gateway presents the available options to the
caller using the selected VXML template and the caller vocalizes
the state reporting option or options selected. The VXML gateway
uses ASR to identify the audible renderings of the KW and fills the
appropriate fields with the choices. Example state reporting
options may include "ready", "not ready", "busy", and so on. More
complicated reporting options can include "ready on mobile",
"ready, page only", "ready at time xxx for period of xxx", "ready
for IP telephony only" and so on. In addition to standard
telephony-type states, location state, device state, designated
communications device state, itinerary or job specific state, and
many other reportable states can be conceived and added to a KW
VXML reporting capability. It is assumed at step 2102 that the VXML
gateway already has the appropriate VXML script for caller
interaction according to the call intent. However, in one
embodiment, a preliminary interaction takes place with the caller
to determine which VXML script must be executed and an additional
step for communication with a VXML Web server to obtain a proper
script is added between steps 2102 and 2103.
At step 2103, the VXML gateway sends the completed VXML back to the
Web server and the server converts the VXML data into XML-based
data using a Web application analogous to application 1908
described with reference to FIG. 19.
At step 2104 XML-based data is sent to the communication center
server running KWP software. The XML-based data reports the correct
state information recognizable by KWP. At step 2105 the KWP within
the center notifies the CC environment of any required actions
resulting from the state reported and, if required performs
configurations and related tasks. These actions might include CTI
or non-CTI switch configuration, database entry or access, queue
configuration, routing routine pre-setting, and tasks that are
subsequently initiated and performed through outbound communication
to the remote KW workplace. The exact type of action or actions
performed will depend on the nature of the state report received.
The actions are automated by commands resulting from interpretation
of VXML fields filled from audio recognition.
The CC environment is now aware of the state of the particular KW
that reported and can manage and track his or her activities. All
of the management tasks that may be performed or states set within
the communication center environment were communicated from a human
KW using VXML to a center application capable executing any
required tasks resulting from reported state according to
enterprise rules governing those tasks. The method of VXML state
reporting can be accomplished from any telephone including a remote
phone used out in the field and away from any center connected
workplace.
FIG. 22 is a process flow diagram illustrating steps for VXML-based
transfer of call data to a remote KW from a communication center
according to an embodiment of the present invention. At step 2200
an incoming call destined for a remote KW arrives at a center
switch analogous to switch 316 of center 300 described with
reference to FIG. 19 above.
At step 2201 IVR interaction solicits call related data from the
caller. Call related data includes but is not limited to caller
identification data; determining purpose of the call; determining
payment method; determining if additional (center stored) data is
required to complete the transaction; and so on. In one embodiment,
the IVR system may be VXML-enabled and ASR is used to interact with
the caller. In another embodiment touch tone interaction is
used.
At step 2202 the solicited data is processed at a server connected
to the center switch for routing purposes and to package the
solicited data for upload to a VXML Web server. If the interacting
IVR is VXML-enabled, it uses VXML scripts that can be uploaded as
they are to a VXML Web server. If the IVR is not VXML-enabled then
the touch-tone responses of the caller are interpreted as XML-based
data by KWP and sent to the VXML server for VXML script generation.
In this case any VXML Web page generated simply contains the
instructions for producing the required one-way voice dialog to the
KW.
At step 2203 the caller is routed according to in-place routing
rules to the registered KW DN assuming a ready and available state.
At step 2204 the switch-connected server sends the solicited data
to the VXML Web server in the form of VXML data, if so enabled, or
in the form of XML-based data that can be used to generate a VXML
script.
At step 2204 the VXML Web server provides a VXML script containing
the instructions for voice synthesizing of the data, the data
provided in the appropriate dialogue fields of the VXML script to
the VXML gateway.
At step 2205 the VXML gateway dials the DN of the KW and renders
the data as a voice media stream to the KW when the call is
answered. The gateway uses TTS rendering to synthesize the dialogue
fields into a media stream.
In one embodiment, the KW may already be on the call with the
routed caller, in which case he or she places the caller on hold to
receive the voice data from the VXML gateway. The KW can record the
stream, take notes or order the stream to repeat. The stream can
include information solicited directly from the caller as well as
information about the caller that was retrieved at the center from
center-housed data during interaction with the caller at step 2201.
The stream can be sent to any regular telephone used by the KW and,
in some cases may be sent to any additional registered DN used by
the KW simultaneously with the phone used for taking calls.
Using this VXML-based method, important data about a call and
caller can be forwarded to a remote KW even if the KW has no CTI or
other connect ability to the center data or remote workplace data.
Therefore, the KW can provide complete service to the caller from
the remote DN.
FIG. 23 is a process flow diagram illustrating steps for issuing a
VXML-based alert to login and receive a KW update to a remote
workplace. At step 2300 a center application initiates an update
request to KWP within the communication center. Virtually any
automated center routine may make such a request. It is assumed
herein that at the time of update, the KW remote workplace is not
logged into the system or not online. At step 2301, KWP running on
a center server processes the request, packages it for upload and
uploads the XML-based data to the VXML server.
At step 2302 the VXML server generates a VXML script containing the
update data in the proper dialogue field or fields and serves the
script to the VXML gateway for interpretation and synthesizing. At
step 2303 the VXML gateway dials the DN of the KW and executes the
VXML dialogue as a voice stream when the KW answers the call. At
step 2304 the KW logs into the center system and receives the
update through the ISCC compatible network. The addition of VXML
voice notification capability can be used to alert remote KWs in
the field to login at certain times to receive certain data updates
or workplace configurations for specific center campaigns. Load
balancing can be practiced among a plurality of KWs who are on call
with automated outbound VXML alerts going out to stand-by KWs to
call them in to handle peak call loads based on a pre-set call
threshold ceiling.
It will be apparent to one with skill in the art that the methods
and apparatus of the present invention can be practiced from any
type of communications network including over the Internet network
including bridged communications networks of wireless, COST, and
DNT forms. VXML management and state reporting can be practiced
using only standard COST telephones without requiring any software
on the end communication device.
The method and apparatus of the present invention should be
afforded the broadest scope in view of the many possible
applications, many of which have been detailed above. The spirit
and scope of the present invention is limited only by the claims
that follow.
