FIELD OF THE INVENTION
[0002] The invention relates to a system and method for a caller to
obtain various levels of fulfillment, research, two way
communication, and other services utilizing wireless communication
products. The system includes one or a plurality of wireless or
cellular telephone users connected via cellular service or other
wireless service providers to a central or regional messaging and
fulfillment center. Advanced interconnection and caller location
can be achieved via the Public Wireless Network (PWN) using the
Integrated Services Digital Network (ISDN), Dialed Number
Identification Service (DNIS), or the intelligent network. A method
for dynamic modification of traditional wireless billing methods to
(i) divert billing to third parties, (ii) block roaming wireless
users, treat them as callers local to the system they are operating
in or process roaming billing in a tradition means after acceptance
of billing responsibility by the caller, and (iii) change the
billing party for wireless and Plain Old Telephone System (POTS)
services during the pendency of the call is additionally
implemented.
BACKGROUND OF THE INVENTION
[0003] Wireless communication technology provides accessibility of
communications for callers from virtually any location. While radio
has provided a wireless medium for delivery of advertising messages
for decades, the radio medium has limitations for advertisers based
upon the cost of on-air time and programming schedules. Road
signage has clear space limitations coupled with minimal "viewing"
periods during which a prospective customer is exposed to the
message.
[0004] Since many prospective customers now travel regularly with
wireless telephone equipment at the disposal, it may be
advantageous to provide advertising services via wireless telephone
linking. From a marketing perspective, a system for wireless
telephone delivery of advertising messages is ideally one in which
the prospective customer initiates the call, thereby eliminating
the time and cost expenditures related to "cold-call" advertising
delivery services of the past. In addition, the call should be free
to the prospective customer and the system should be equipped to
modify existing billing procedures in order to shift the cost of
the advertiser.
[0005] U.S. Pat. No. 5,131,020 of Liebesny, et al. discloses a
method for providing traffic updates to cellular telephone
customers within a regional calling area. User input of a code
representing the traffic zone of interest to the user automatically
connects to either a live operator or a taped message including the
requested traffic information. While the Liebesny method does
deliver user-requested information via cellular linking, its
delivery is local and the messages fixed in scope.
[0006] U.S. Pat. No. 5,214,793 of Conway, et al. provides a system
for automatically delivering advertising, traffic status,
directions, or other information to motorists having microwave
transmitter/receiver systems at their respective locations. The
requirement that the Conway user have the microwave equipment
clearly limits the prospective audience and transmission delivery
capabilities of such a system.
[0007] U.S. Pat. No. 5,216,703 of Roy provides a cellular switching
system whereby indicia dialed by the user after a cellular star (*)
number is unique to a specific third party advertiser (TPA) and is
used to direct the user's call through a special trunk in the
switching system in order to deliver the TPA's message to the user.
The Roy system utilizes cellular technology to enter into a trunked
system, but is clearly limited in its ability to provide switching
through an extensive network of advertisers and providers.
SUMMARY OF THE INVENTION
[0008] Pursuant to one embodiment, a prospect driving past an
outdoor signboard will observe the advertiser's message, which will
include a call-to-action, for example "CALL *500" or selected other
abbreviated access code using the driver's cellular phone. In
another embodiment, a prospect driving and listening to a radio
broadcast will be prompted to dial *4AD (for example) by trailers
to commercials. In a third embodiment, drivers passing highway
interchanges with informational gas, food, and lodging signage will
also be prompted to "CALL *522", for example. Other uses may
involve prompts located on buses, on board commuter trains, in
public stadiums, etc.
[0009] Following the general direction to dial the access code,
each individual commercial spot will contain a one or more digit
identifying alphanumeric code known as the Advertiser Identifier.
Hence, a typical outdoor signboard will contain the following:
1 CALL *500 SEND 1234 No Airtime Charges
[0010] The prospect, held captive in his or her car, perhaps
sitting in rush-hour traffic, will utilize their cellular phone to
seek out additional information on the advertised product or
service. In the case of the highway interchange, the prospect can
obtain detailed information of the products or services (e.g.
shopping, food, lodging, gas, etc.) available within three to five
minutes of that particular interchange.
[0011] In one embodiment, once prospects call *500 or other
designated access code, they will hear a short message welcoming
them to the system and prompting them to either dial or speak a one
or more digit identifier, for example the name of the advertiser or
a product name. After dialing or speaking an identifier, the
customer will enter either an automated messaging system or be
greeted by a live operator. Due to the inherent limitations of
outdoor and radio advertising in terms of communicating a detailed
message of product and service benefits, the additional level of
transmitted information will have a high perceived value to both
the advertiser and the primary media company.
[0012] Based upon the particular services contracted, prospects can
be provided with a menu of additional customer services including:
the mailing of product/service information to their home or
business; an audio listing of local retailers and their addresses
or telephone numbers (with directions under certain circumstances);
direct product sales; couponing; sampling; sweepstakes entry;
polling; optional transfer to a retailer; optional transfer to the
advertiser's customer service number; optional transfer to the
advertiser's mail order desk; or, an opportunity to participate in
a brief survey (for which the prospect may receive some nominal
compensation or award).

[0043] TDMA: Time Division Multiple Access
[0044] FIG. 1 provides a process overview. There are essentially
four distinct basic functions which comprise the process flow, the
details of which are discussed below. These elements are (1) the
call initiation at 103, the detailed process flow for which is
provided in FIG. 4; (2) switching or other elements of the PWN at
104, as further detailed in FIG. 6; (3) transfer of the call over
the PSTN at 105, as further detailed in FIGS. 8 and 9; and (4)
control over fulfillment and feedback to the user, as detailed in
FIG. 10.
[0045] The call initiation function is generally outlines as boxes
101-103. At box 101, the prospect receives the sensory input which
prompts use of the system, either via road signage, an audio
message from the radio, etc. Upon manual input to a telephone, at
102, the prospect (hereinafter referred to as the "caller") calls
in to obtain the information suggested by the sensory input. Box
103 refers to the initiation of the wireless call from the system
perspective, as opposed to the caller input and transmission from
the caller's telephone. As an alternative to the caller manually
placing the telephone call, the call may be initiated by automatic
processing, as will be discussed below with reference to FIG. 4.
Box 103 initiation of the wireless call by the system results from
either a third party remote triggered signal or a local independent
transmitting signal and includes the mobile identification number
and the electronic component's serial number for subsequent access
and billing verification.
[0046] Subsequent to system initiation of the wireless call, the
call is transmitted along the Public Wireless Network (PWN) at 104,
for caller identification, billing verification and/or
modification, and routing to the PSTN, as is further detailed
below. Thereafter, service is provided along the PSTN at 105 and
the call is ultimately provided for routing to the messaging center
at 106 and thence handled at the gateway to the target fulfillment
center, at 107. Clearly, it may be possible to route the call and
connect to the target center using only the wireless network,
particularly for communications between geographically local
callers and target locations. However, accessing the PSTN provides
greater transmission reliability and increased geographical
distribution of prompting media and fulfillment centers to realize
a national system.
[0047] FIG. 2 provides a more detailed description of the path of a
call through the inventive system. From the wireless telephone, 110
of the block diagram, the call is sent with the caller input access
code, which is an abbreviated dialing code to access the system,
such as *500. In accordance with prior art wireless telephone
service, the call is communicated to a base station remote switch,
111, at which a base station controller relays the call to the MTSO
or other wireless service switch 112, as appropriate.
[0048] Central to the operation of the inventive system is the
functioning of wireless switch 112. This switch must recognize the
caller seeking to utilize the system and must recognize the access
code and compare it to entries in a database of approved codes. The
switch 112 also performs recognition on the subscriber identity and
the subscriber location, and determines the billing status for the
caller as either a local system user or a roaming user (billing
detail is provided in FIGS. 7 and 11). Depending upon the billing
status determination (i.e., local or roaming), software or firmware
at the switch is utilized to modify established billing procedures
and to create a new billing record for the third party provider of
the service under a preset billing arrangement. Alternatively, if
the system determines that the caller is roaming and the caller's
service provider has not arranged to allow treatment of the call as
local, the system queries the caller if the caller will agree to be
billed for all airtime charges. Absent caller acceptance of billing
responsibility, access to the system is blocked. Switches which can
be adapted to perform the foregoing functionality include
AT&T's System 85 5E Diffinity Generic 2.
[0049] Assuming favorable determinations with respect to
verification of the input access code, of subscriber identity, and
of caller billing, switch 112 converts the access code to a land
line 800-number and routes the call to the PSTN's central office,
illustrated as block 113. The central office of the PSTN accepts
the call and recognizes it as belonging to the system described by
preassigned POTS numbers and, if necessary, translates the land
line 800-number to a Routing Telephone Number (i.e., the POTS
number). Typically, the preassigned POTS numbers will be
traditional 800 service numbers. Such service is exemplified by
AT&T's MEGACOM 800 Service with a Customer Specific Term Plan
II (CSTP II). Typically, such service will also utilize on-line
call detail data software to collect information about the system
calls such as connect time, the 800 number sent by the wireless
carrier, call disposition, date and time of call, call duration,
and the ANI of the caller. Such service is generally described as a
high capacity digital, direct access, virtual banded, inbound
calling service, and requires a dedicated connection between the
serving central office and the target location, as is known to one
having familiarity in the art. Depending upon the access code, and
the nature of the fulfillment of a call bearing that access code,
the call may be routed along one of several call completion paths
at the PSTN, as further detailed in FIG. 3.
[0050] Call completion involves selecting the long distance carrier
of choice and routing the call to this carrier's Point of
Preference at 114 via the selected Routing Telephone Number. This
procedure is implemented using either a conventional in-band Dual
Tone Multi-Frequency (DTMF) system or by packetizing the digits and
processing them via a Signaling Transfer Point (STP) 121 into the
Signaling System 7 common channel signaling network 122. If the
Point of Preference is local to the messaging center, the
connection is made, via Long Distance Trunk 115 using the dedicated
800-number, to the local Point of Preference and thence to the
target location messaging center 119 using T1.5 or T3 access lines
118.
[0051] When the carrier Point of Preference is not local to the
messaging center, the call is routed via the network to a Signal
Transfer Point 121 (also referred to as a Signal Control Point,
SCP) or other network node that contains databases that support
Cellular Linking services. Thus, from the Foreign Data Base at 123,
access is made to the Central Office 117 and ultimately to the
Messaging Center 119.
[0052] By means of an Integrated Voice Response (IVR), the mobile
wireless subscriber is thus able to obtain information and/or
fulfillment services. Subsequent to initial call dialing the mobile
subscriber inputs information on the geographic location of the
mobile terminal involved in the call, or alternatively inputs
location information received from one or more of a variety of
media including, but not limited to, contacts with other cellular
subscribers, broadcast radio, especially programs dealing with
traffic conditions or similar events, global positioning systems,
intelligent highway systems, roadside signs displaying city
boundaries and street names, personal observation, information from
other passengers, etc.
[0053] Electronic positioning data from consumer equipment within
the car may be converted into DTMF tones and coupled to the mobile
wireless terminal for automatic transmission over the cellular
network. Location data that does not form part of the inherent
capabilities of the cellular system and is not available in
electronic form will be input to the wireless terminal as
additional dialed digits that will be requested by the IVR system
established by Cellular Linking at the informational and
fulfillment database.
[0054] The location of the mobile wireless terminal will be
computed by a processor and special software permits a display of
the cellular service area containing the terminal to be cross
referenced against positional data input by the customer as dialed
digits. Location information obtained in this manner is used to
more readily fulfill the Cellular Linking customer's needs for the
services requested from Cellular Linking's third party service
providers.
[0055] Certain new kinds of digital cellular systems, such as GSM
and other TDMA and CDMA systems, and PCS networks may have the
ability to process special numbers, identify subscribers including
roamers, authorize alternative billing procedures, and identify
mobile terminal locations more readily than conventional AMPS and
NAMPS systems. In such cases, special location processing software
that forms an inherent part of the mobile switching system will
determine the location of the mobile wireless terminal,
transmitting this information along with other necessary data to
the Cellular Linking central database.
[0056] FIG. 3 describes three alternative call path routings based
upon the specific access code dialed by the user. Upon recognition
of the access code at 131, as conducted at the MTSO or other
wireless service switch, wireless switch translation is conducted
at 132. Since access codes are assigned based upon the type of
fulfillment service, different categories of access codes will be
automatically routed at switch 112. As shown in FIG. 3, three
representative call routing paths may be automatically selected,
though it may be possible to integrate many more than three
possible paths into a wide-scale system.
[0057] In accordance with the representative routing plan, an
access code *# X--X--X, 133, denotes routing via the PSTN, at 134,
to a live operator, at 135, and prompting, at 136, of the
advertiser identifier at the target location. Given an access code
*/# Y--Y--Y at 143, routing proceeds via the PSTN at 144 to an
audiotex service bureau, at 145, and prompting of the advertiser
identifier at the target location at 146. Finally, access code */#
Z--Z--Z at 153 denotes routing to the PSTN at 154 and 155 and
prompting of the advertiser identifier within the PSTN at 156 with
subsequent direction of the call to the target location which may
be an advertiser's premise at 157.
[0058] The use of the above described call path routings allows for
minimal access codes to be required by the system and provides for
cost efficiency to the system by routing a majority of calls
without prompting of the advertiser code within the PSTN.
[0059] FIG. 4 describes the initiation of the wireless call, into
FIG. 1, box 103, using manual or automated means. Note the
following means for call initiation:
[0060] (a) Sensory input 101 and manual initiation 102: as shown in
FIG. 1, the mobile subscriber receives a sensory input from any of
a variety of physical and electronic promotional and/or advertising
media, 101a through 101e, including, but not limited to, pagers,
cellular calls, broadcast radio, billboards, roadside signs,
printed media, vehicle sign panels, or other means. Upon receipt of
the sensory input at 101, the caller manually conducts the
telephone call at one of the input modules 102a through 102d.
[0061] (b) Automated signal initiation is triggered through the
mobile wireless antenna or a vehicle antenna, 202a or 202b, upon
receipt or input from any of the components 201a through 201d which
can communicate with the antennas. Such signal to be originally
generated by AM or FM radio transmitters, satellite feed, roadside
low power transmitters, or other means triggers the automated
signal at 202.
[0062] (c) Third party remote triggered signal at 302 and
subsequent initiation parallels the automated signal at 202 since
such signaling is automatically conducted by the mobile wireless
antenna or the vehicle antenna 302a or 302b. The input, though, may
be transmitted through further means, 301a through 301g, including
cellular or other wireless telephony equipment.
[0063] A sensory input that contains any information that
encourages the subscriber to utilize the invention may prompt the
customer to initiate a wireless call using the keypad of a cellular
telephone to dial or speak a set of digits commencing with *, or
some other call prefix such as #, utilizing a special code. These
digits, along with the command SEND activate the cellular
communications system and connect the subscriber by means of a
formatted mobile message through a wireless channel via base
station firmware over a T1 or other kind of link to the line
interface at the MTSO where the call is demodulated and connected
to the central processor at the mobile switch. Using the same input
media, an advertiser can access the system to update or modify
fulfillment data from a remote location using the appropriate (*)
or (#) identifier or a POTS wireline.
[0064] FIG. 5 describes the integration of the wireless telephone
or specifically the mobile wireless transmitter and receiver 210 to
a vehicle transporting the caller. The wireless telephone may be
connected by a hardwire interface to a vehicle's central key pad
211 located on the steering wheel or other convenient location.
Such connection will permit easier use of the invention and will
allow for visual confirmation of system functions through the
vehicle's heads-up-display capabilities, at 212.
[0065] The wireless telephone may also be connected by a hardwire
interface to a vehicle's central computer 213 to allow both
components to operate more effectively. The wireless telephone may
access memory or processing capabilities of the central computer to
enhance its function as a communications device. Similarly, the
vehicle may access the transmission and reception capabilities of
the wireless phone to perform a variety of diagnostic, safety or
passenger convenience tasks.
[0066] Yet another arrangement provides that the wireless telephone
be connected by a hardwire interface to a vehicle's video terminal
214 to allow display of telephony functions or the receipt and
display of video messages sent by wireless means to the user. A
hardware connection can also be made to a vehicle's positioning
system 215, such as GPS, and automobile mapping system 216 in order
to facilitate communication of position data or to allow
advertisers to transmit data containing directions or
location-related information. Integration of the wireless telephone
210 to the vehicle's safety system 217 provides for automated
transmission of emergency messages. When coupled with the vehicle
positioning system 215, such emergency messages may contain the
specific location of the troubled vehicle or user. Vehicle location
data is often valuable for both caller purposes (e.g., emergencies)
and cellular system efficiencies, as evidenced by the systems
disclosed in U.S. Pat. Nos. 5,327,144 and 5,343,493. Cellular
location can be determined by one or more of the following
means:
[0067] A. Identification of the MTSO which routes the call to the
PSTN;
[0068] B. Identification of the cell, sub-cell, or microcell from
which the call was placed or is currently being serviced;
[0069] C. The use of the intelligent network such as ISDN or DNIS
information;
[0070] D. The signal strength of the call;
[0071] E. The call history;
[0072] F. Alternative visual identification; or
[0073] G. Vehicle based locations systems.
[0074] The caller's location may be determined by identifying the
subscriber's position within the cell by one or more of the
following techniques:
[0075] (A) To cell level by identifying the base station taking
part in the transmission; to sub-cell level subsequent to a
hand-off when further data becomes available as to the location of
the mobile subscriber.
[0076] (B) To sub-cell level for small cells from signal strength
and azimuthal data at the directional antenna as follows:
[0077] (1) Antenna at cell base station receives signal from
subscriber's terminal;
[0078] (2) Signal is fed via antenna combiner to radio transceiver
module;
[0079] (3) Signal is analyzed by radio controller which determines
signal strength and azimuth using directional antenna segmentation
techniques;
[0080] (4) Special software program in controller instructs
processor to represent these data in the form of a digital code for
modulating a T1 line or other form of communication channel for
transmission to MTSO;
[0081] (5) MTSO codec demodulates digital signal reproducing
original bit stream sent from base station;
[0082] (6) Call processing software translates this bit stream into
digits recognizable by central;
[0083] (7) Processing unit at centralized or regional messaging
center;
[0084] (8) Software program at center receives digits and compares
these with database of signal strength and azimuthal information on
specific cell base station;
[0085] (9) Special geographical location software package instructs
processor to compute comparative data in terms of geographic locale
of mobile subscriber.
[0086] (C) To cell level for wireless communication systems with
very small cells such as PCS;
[0087] (D) To cell level where more precise location identification
is deemed unnecessary by the third party service provider
responding as part of claimed procedures;
[0088] (E) To sub-cell level for large cells from directional data
collected from non-multipath propagation patterns such as occur in
rural and semi-rural service areas;
[0089] (F) To sub-cell level by using triangulation data from two
or more adjacent base stations;
[0090] (G) To sub-cell level by using location updating procedures
from previous calling patterns established by that subscriber due
to frequent and continued use of the invention; and
[0091] (H) To sub-cell level from subscriber-input data received
from personal observation of external information including but not
limited to numerical data displayed on billboards or other visible
advertising media, instructions received over broadcast radio
channels, information gathered from other visible sources,
information received from fellow passengers in the vehicle equipped
with the mobile radio terminal; other personal third party sources;
information previously provided to the subscriber as part of
commercial agreements.
[0092] The caller location information can be used to reconnect
inadvertently dropped calls. The caller's location or home or
office phone number can also be used to identify a local dealer by
reference to a computerized vertical-horizontal file, as detailed
in U.S. Pat. No. 4,757,267
[0093] Integration of the wireless telephone to the Intelligent
Vehicle Highway System (IVHS) 219 will provide enhanced features
and further communication abilities utilizing the receiver and
transmitter of the wireless phone. The wireless telephone may also
be connected by hardwire interface to a vehicle's printer or other
mobile facsimile or printer at 218 to allow printed transmissions
from advertisers, including coupons, etc. Finally, the wireless
telephone may be connected by a hardwire interface to a vehicle's
radio 220 to allow audible display of telephony functions or the
receipt and display of audio messages sent by other wireless means
to the user.
[0094] FIG. 6 further describes the functions of the MTSO of the
PWN in accordance with the present invention. The MTSO comprises
the central office computerized equipment that coordinates and
controls the routing and completion of calls in a cellular system.
The MTSO includes a Central Processor (not shown) for identifying,
accepting, and taking action upon receipt of the dialed digits as
part of a Cellular Linking call having a special prefix. The
central processor functions are detailed at FIG. 6.
[0095] At 250, the MTSO receives the abbreviated access code and
verifies both the access code and the caller identity at 251. An
object of the present invention is the use of relatively few digits
as advertiser identifiers to reduce user induced errors in the
system and generally increase user friendliness. The MTSO first
determines whether the received access code is one which the MTSO
recognizes as valid. Assuming validity of the access code, the MTSO
next verifies the caller's identity and approved access to the
system. One or more of the following identifiers can be verified at
the MTSO:
[0096] Mobile Identification Number (MIN) or ANI of the wireless
telephone; Electronic Serial Number (ESN); International Mobile
Station Identifier (IMSI); Mobile Station Type (fixed, automobile,
transportable, portable, aircraft); ANI of the MTSO; Source such as
Mobile Station (MS), Base Station Controller (BSC), Mobile
Switching Center (MSC), Home Location Register (HLR) for fixed
mobiles, Selective Router or other sources; Caller Geographic
Location (latitude, longitude, altitude, resolution which
information is contained in the subscriber's signature only for
cellular or other wireless telephone communication systems that
have the inherent ability to generate and process such positional
data); Billing Number; Subscriber name; Subscriber billing address;
Subscriber home telephone number; Subscriber personal telephone
number; Subscriber priority indication; Priority Access &
Channel Assignment (PACA) level (A,B or C); Preferred language;
and, Home wireless service provider information. As will be
apparent to one having skill in the art, some of the above-listed
information may be automatically appended to the user-input access
code by the wireless telephone, depending upon the specific
preprogramming thereof.
[0097] After caller identification, the user-input access code
digits are provided for analysis and translation at 252 by the
central processor at the switch where software operates on them and
compares them with data received from a number of databases,
253-255. These databases provide data on both calling and called
parties and preferred routing through the network and are integral
to the call processing procedure, examples of these databases being
user files, number tables, access codes and routing tables. The
various data are analyzed and, when the dialed digits and other
transmitted identifiers are approved, the processor creates a set
of translated digits that are returned to the call processing
module for additional actions to be taken, such as determination of
the caller's local or roaming status at 256, billing procedures at
257, and call routing.
[0098] At 257, software within the central processor at the MTSO
insures that the mobile subscriber making the Cellular Linking call
is not billed for air time, local or long distance call charges, or
local and remote charges. In the case of roamers this may be done
by creating a pseudo-cellular number for the Cellular Linking
provider number for third party billing procedures, or by some
other means which will be apparent to one having skill in the art
(see: e.g., U.S. Pat. No. 5,216,703). Billing modification, with
the object of allowing the MTSO to accept calls it otherwise would
not, is further detailed in FIGS. 7 and 11.
[0099] Finally, upon successful completion of steps 250-252, 256
and 257, at which time the access code has been recognized, the
subscriber identity has been recorded, the presence of roamers has
been determined and the necessary roamer billing acceptance
procedures have been started, the access code is converted to a
landline Cellular Linking number at 258 and the call routing
software at the MTSO instructs the central processor to proceed to
the next stage of telephone network call completion procedures by
routing the call to the PTSN at 259. Connection and transmission
may be based on TDMA, CDMA, GSM, SMR, PCS or N-AMPS technology, as
would occur to one having familiarity with the subject
technology.
[0100] If the above process is interrupted at any point after
receipt of the mobile subscriber signature, further special
software instructs the switch to send a recorded message that
prompts the subscriber to redial the complete number sequence. On
receipt of the digits, the call validation and call processing
procedures are restarted.
[0101] FIG. 7 further describes the billing modification processing
of the invention. Central to the invention is recognition by the
PWN, and specifically the MTSO, that the caller is accessing the
invention. The PWN must identify the caller as a local subscriber
or a roamer at decision box 280. Local callers are automatically
granted access to the system and the call billing file is altered
to delete any charges to the caller for the call, at 281. In
addition, a special billing record is established for the third
party service provider at 282 including accessing the third party
provider's plan, as necessary. The call is then processed at
284.
[0102] If the determination at decision box 280 is that the caller
is roaming, the MTSO central processor next determines if the
caller's service provider will allow treatment of the call as
local, with the attendant third party billing at 285. If the
service provider, to which the roamer is a subscriber, has agreed
to allow roamers to be treated as local for purposes of using the
present invention, the roamer's service provider is bypassed and no
billing or call information is forwarded. A third party billing
record is created at 282 and the call progresses at 284.
[0103] If the roamer's home carrier has not established a protocol
for allowing its roamers to be treated as locals on the system
(i.e., a "no" determination at decision box 285), then the roaming
caller is notified at 286 that they have been identified as a
roamer and that access to the cellular linking system will only be
provided if the caller agrees to accept airtime charges. If a
caller acknowledges acceptance of such charges, by depressing SEND
or by other means conveying a "yes" decision for box 287, the
acceptance is confirmed at 288 and the caller is permitted access
at 286 and is charged in a traditional manner.
[0104] If the roamer's home carrier has not established a protocol
for allowing its roamers to be treated as locals on the system and
the roaming caller fails to acknowledge acceptance of airtime
charges at 287, then the roaming caller is blocked from the service
at 289.
[0105] FIG. 8 provides a detailed description of the call
processing in accordance with the present invention when ISDN
technology is available. The long distance carrier's data base
functions are central to the implementation of the present
invention which relies on ISDN technology. ISDN provides a common
architecture for the development and deployment of digitally
integrated communications services, using out-of-band signaling to
permit the user's equipment and the PSTN to exchange control and
signaling information over a separate channel from that which
carries voice or other user information. ISDN lines are divided
into bearer ("B") channels and a supervisory control or data ("D")
channel. The D channel is used for out-of-band signaling and the B
channels carry digitally encoded voice or other traffic. The D
channel also carriers information about caller identification which
can be used in the present invention to determine approximate
geographic location.
[0106] The invention utilizes ISDN technology to acquire the ANI of
the LEC, MTSO, or caller and combine the geographic locator element
of this ANI with the advertiser identifier to create an unique
advertiser code and access fulfillment commands. At 310, the call
is received at the PTSN, the identity of the ANI is checked at 311,
and the call is routed to the target location at 312. The ISDN
information is read on the D channel at 313, the D channel protocol
conducted at 314, and the ANI verification conducted at 315 and
316. Once the ANI has been confirmed, the call is answered on the B
channel at 317, with audible prompting to the caller being provided
at 318. The ANI and the advertiser code (from the caller) will be
linked at 319 and the database accessed at 320 in order to fulfill
the call (i.e., retrieve and deliver the advertiser's message).
[0107] FIG. 9 is a process flow utilized by the present invention
when implemented with DNIS technology. DNIS technology allows the
PSTN to transport information on the number dialed or in this
application the POTS "800" number translated by a given wireless
provider. Such information can then be read by the target location
to determine via a preassigned look-up table the approximate
geographic location of the caller. Variants of the present
invention which rely only on DNIS technology may utilize T1 access
with in-band signaling only.
[0108] Upon translation of the access code to the 800 POTS number,
at 330, the call is routed to the LEC at 331. Attachment of the
DNIS data using the long distance carrier database is conducted at
332 and the call routed to the target location at 333. At the
target location, the call is answered at 334, the DNIS data
received at 335 and the caller prompted to provide the advertiser's
code at 336. Linking of the DNIS and the advertiser's code is
conducted at 337 followed by accessing of the fulfillment
information. The inventive process thus utilizes DNIS technology to
acquire the ANI of the transcribed POTS "800" number and combine
the geographic locator element of this ANI with the advertiser
identifier to create an unique advertiser code at 336 and to access
fulfillment commands at 338.
[0109] FIG. 10 further describes the components of the invention
related to the target, or fulfillment, location. The target or
fulfillment location may include a voice activated switch 400 to
welcome the user and prompt verbal entry of a required alphanumeric
code. An alternative key pad switch 401 may be available for
receipt of keyed input of the required code. When the caller
provides an audible identifier for interpretation by speech
recognition software at the system's messaging center, inability to
recognize an identifier, whether incorrect or unrecognizable for
other reasons, will result in a prompt for the caller to repeat the
audible identifier. If still not recognized as correct, the system
will prompt the caller to enter the identifier using the phone
keypad. In some instances, a live operator may answer the call and
deliver the request for an identifier or trigger a recorded message
requesting the identifier. The operator would then retrieve the
advertiser specific files manually or by entry to one of a
plurality of networked PC's, 402-404, after hearing the user speak
the alphanumeric code.
[0110] Whether automatically or manually queued, the front end PC's
select the relevant advertiser file, deliver the advertiser message
and, if necessary, route the call for further processing (e.g.,
demographics information gathering; sweepstakes entry; caller
ordering with attendant information gathering including credit card
or other personal account billing verification based upon input
provided by the user either by magnetic card reading or secured
transmission of alphanumeric information entered by the caller at
the time of ordering or preprogrammed into the telephone, which may
be conducted directly by an entity at the messaging center or may
require transfer of the call to the advertiser's order desk; survey
participation, appointment scheduling; etc.). As appropriate, one
or more local servers 406, or one or more remote servers 409,
receives call fulfillment information, as does the system provider
server 407 for tracking of system use, advertiser and caller
demographics and billing data, etc.
[0111] The system's target or fulfillment center also includes a
customized administrative database 405 which notes the time of
calls, duration of calls, location of caller, number of calls for
each identifier, monitors volume and other physical parameters of a
call, and administrates billing of calls. Other database
information which may be stored and/or updated includes a caller's
social security number, address, credit or debit card number,
sizing and credit history. In those variants of the present
invention which utilize ISDN technology, the target location must
use an ISDN compatible switch with T1 or T3 cards, such as the
Varilink CSU Model 551 or Northern Telecom's SL1 Meridian Model
Option 81. ISDN processing also requires Extended Super Frame (ESF)
Binary Eight Zero Suppression (B8ZS) signaling.
[0112] FIG. 11 describes the advanced billing process flow for the
present invention. Although one of the objectives of the system is
to control call length to be within predefined parameters
established by the advertiser and the third party service provider,
call length can be extended if the caller so desires and is willing
to incur the additional expense of the call. In that way, extended
communication with the advertiser, their dealer or representative
can be provided without requiring the caller to initiate a second
call.
[0113] FIG. 11 describes the process whereby the billing of the
wireless land-based telephony charges revert back to the caller
from a given point during the pendency of the call. If, at 420, the
caller desires to transfer the call, or to extend the duration of
the call beyond the time preset by the third party billing
arrangement and monitored by the system, the caller is notified, at
421, of the caller's need to accept billing responsibility for the
remainder of the call. At decision box 422, the system ascertains
whether the caller is willing to accept the billing responsibility.
If not, the call is terminated at 423. If, however, the caller will
accept billing, the system notifies the wireless carriers to modify
the billing process at 424. The wireless carrier then verifies the
caller's credit at 425 and creates a new billing records at 426.
Thereafter, the call is extended, or transferred as required, at
427.
[0114] Such billing reconfiguration requires utilization of the
intelligent network such as ISDN in order to signal the wireless
provider of the need to modify is billing process. If transfer is
required, the call is transferred to a second target location using
traditional POTS means.
[0115] The wireless mobile communications system as taught provides
that the caller not be charged for any connection or service time
but rather the targeted receiver is charged for the call using a
specific dialing prefix. In the alternative, the targeted receiver
can be charged for the call based upon a specific and dedicated
frequency to be used for all such calls. Yet another arrangement
provides the targeted receiver be charged for the call based upon a
specific and dedicated numbering code to be used for all such
calls.
[0116] A final billing arrangement can provide that the wireless
receiver of a call is not charged for any connection or service
time but rather the caller is charged for the call based upon:
[0117] (A) A "collect call" type system wherein the key pad of the
receiving cellular phone or other wireless communications device
affirmatively indicates that the caller willing to pay charges.
[0118] (B) A "collect call" type system wherein some non-key pad
indicator on the receiving cellular phone or other wireless
communications device affirmatively indicates that the caller
willing to pay charges.
[0119] (C) The receiving wireless caller answering the call by
pressing >send! alone to answer or >send! plus a second key
such as >#! or >*!.
[0120] Several advanced system features may be incorporated to
enhance the capabilities of the inventive system, including an
encryption system to secure financial data transmission,; automatic
downloading of data to the caller's wireless phone or via the phone
receiver to other vehicle systems; concurrent transmission of voice
and data; and integration of automatic directories of advertiser's
codes.
[0121] Additional advantages and modifications will readily occur
to those skilled in the art. Therefore, the invention in its
broader aspects is not limited to the specific details provided
herein. Accordingly, departure may be made from such details
without departing from the spirit and scope of the appended
claims.
