but otherwise reserves all copyright rights whatsoever.
BACKGROUND
[0003] 1. Field of Invention
[0004] This present invention relates to the field of
communications and, more specifically, to methods and systems for
transmitting and receiving messages
[0005] 2. Description of Related Art
[0006] In today's world, information exchanges between people in
many ways. In that regard, numerous types of communication systems
exist for this purpose, including, for example, radio, television,
cable, internet, two-way radio, cellular telephone systems, LANS,
WANS, and optical communication systems. Advances in technology
enable the distribution of information faster and more efficiently
than was possible just several years ago. Some information is
trivial, while other information can be critical and needs to
travel immediately to the recipients.
[0007] In responding to emergency situations, the need for
particular information relating to the emergency is sorely acute.
Such emergency related information may include a threat of a
disastrous event, terrorism induced threats and events, location
and description of the event, evacuation instructions and status,
and the status and coordination of the response to the threat or
event. This information is invaluable to government and private
agencies responsible for preventing, assessing, and responding to
such events, and also by those on the front lines that are present
at such an event and are dealing with it directly (e.g., "first
responders" such as police, fire and rescue, emergency medical
personnel). Fast and reliable dissemination of emergency
information to emergency response personnel is necessary in order
for the emergency to be contained and neutralized with minimal loss
of life in terms of both emergency personnel and the general
population.
[0008] Therefore, systems have been deployed to assist emergency
personnel and responsible agencies in disseminating emergency
alerting messages and notifications to emergency response
personnel. However, such existing systems are notoriously slow and
unreliable. Furthermore, many of these systems lack any practical
confirmation mechanism from which the alert originator can
ascertain whether or not a sufficient response team has been
assembled or dispatched. For example, many agencies at all levels
of government may employ a telephone based auto-dialer system in
which emergency response personnel are contacted by telephone
individually seriatim. Such systems may include, for example, a
human dispatcher who simply begins contacting, one at a time,
individual members of an emergency response team by dialing the
emergency contact telephone number for each team member whose name
appears on a predefined list corresponding to the type of threat or
emergency. Alternatively, multiple operators may dial emergency
personnel in parallel, or a computer-based auto-dialer may be used
in which a voice message is played over the telephone to the
answerer. Such systems and methods are plagued with limitations and
inefficiencies, not the least of which is the slow speed at which a
response team can be contacted and assembled, and provided with
relevant information concerning the emergency. For example,
telephone based auto-dialers typically contact emergency response
personnel one-at-a-time, resulting in a slow notification process.
Even in the case in which multiple dispatchers or auto-dialers are
used, coordination problems may ensue in tracking which personnel
have been reached and given positive confirmation of their
response. For computer-assisted auto-dialers, the voice mail
message played to an individual may not provide significant
information specific to the emergency and, further, may not be
customizable to include important information concerning the
particular nature of the threat or event leading to the emergency
situation.
[0009] Over and above all of these limitations, all voice-based
existing systems and methods depend on the reliability and
availability of the telephone service in providing emergency
message notification. Unfortunately, both land line based and
mobile telephone communication are vulnerable in times of
emergency, in terms of both reliability and availability. Because
telecommunication systems are designed to accommodate a statistical
average number of voice users having a particular call duration
(e.g., commonly modeled using the Erlang probability density
function), voice circuits may become saturated or overloaded in an
emergency situation in which many callers are attempting to connect
using the voice carrying network. Wireless voice-based
communications systems such as cellular telephone systems and their
digital counterparts are also susceptible to overloading due to
bandwidth limitations of and shared access to the radio channel.
These situations occurred in certain metropolitan areas during the
events of Sep. 11, 2001.
[0010] First responders may also use one or more radio-based
systems for coordination and status of response activities,
typically at the site of the emergency. Such radio systems may be
simplex systems (i.e., one-way voice traffic only) and have a
limited number of frequency channels for communications. In
addition, different agencies and teams typically use different
frequency channels, radios, and/or air interface technologies and
modulation techniques (e.g, Single Side Band (SSB), Very High
Frequency (VHF), spread spectrum). Thus, coordination among
multiple government agencies responding to a large scale event is
problematic, if possible at all. The current situation engenders at
least confusion and inefficiency for those responding to
emergencies and, of most concern, the potential for additional loss
of human life.
[0011] Thus, there is a need for reliable and fast communication
systems and methods that overcome these limitations of voice-based
communications for disseminating alerts and notifications that may
be, for example, associated with emergency prevention and
response.
SUMMARY OF THE INVENTION
[0012] The present invention is directed generally to providing
systems and methods for communication among multiple communication
gateways. Furthermore, embodiments may provide non-voice message
delivery to intended recipients with increased speed and
reliability. Embodiments may also provide efficient and
user-friendly systems and methods for non-voice messaging to
multiple users on multiple platforms. In particular, the advent of
consumer wireless devices has provided a powerful, but
underutilized, communication infrastructure. Many such devices may
be included in an overall strategy to place vital information
quickly and reliably to many recipients.
[0013] More specifically, the systems and methods may relate to
non-voice messaging to multiple messaging gateways, and, in at
least one embodiment, to messaging using channels configured for
data or control traffic. Embodiments may also include a
packet-based electronic messaging application that may include a
process for optimizing text message delivery to electronic mail and
SMS (or "text-messaging") gateways. For example, in an embodiment,
methods and systems may be provided for Internet based electronic
messaging to multiple messaging gateways. Embodiments may include
an Internet based messaging application that incorporates a process
for optimizing message delivery to electronic mail and Short
Message Service (SMS), or "text-messaging" gateways. Embodiments
may also include message delivery using pager systems. The systems
and methods may be device and carrier agnostic and conform to
industry Internet and wireless standards allowing it to work with
existing carriers and equipment. Embodiments may provide reliable
and fast alert delivery, simple web-browser based management, and a
networking option for forming messaging coalitions for cross
jurisdictional message sharing that supports agency
interoperability. Embodiments may also include easy interfacing
with existing emergency-management infrastructure to provide
flexible and improved message distribution within and across
organizational boundaries.

DETAILED DESCRIPTION
[0035] The present invention is directed generally to providing
systems and methods for non-voice based communication. For example,
the methods and systems may relate to Internet based electronic
Messaging to multiple messaging gateways. In at least one
embodiment, the systems and methods may include an Internet based
messaging application having a process for optimizing text message
delivery to one or more communication gateways such as, for
example, electronic mail and SMS (or "text-messaging") gateways
[0036] In particular, exemplary embodiments may include
standards-based systems and methods that provide emergency
communications to text message enabled appliances such as, but not
limited to, wireless devices and other such e-mail addressable
delivery points. Such embodiments thereby combine the inherent
redundancy of communication networks such as, for example, the
Internet with delivery to multiple devices per user to provide a
high delivery success rate that persists even in the case of
breakdowns within or overloading of public communication
infrastructures.
[0037] At least one embodiment of a communication system 100
according to the present invention may be as shown in FIG. 1.
Referring to FIG. 1, the communication system 100 may include at
least one messaging subsystem 101. The messaging subsystem 101 may
be coupled to an alert originator 102 via a network 103 and one or
more communication gateways 104 via a network 106. Each
communication gateway 104 may be coupled to one or more user
terminals 105 via a network 107. Further, in an embodiment, the
system 100 may include more than one messaging subsystem 101 (e.g.,
up to "n" such subsystems as shown in FIG. 1). In such embodiments,
one or more of the messaging subsystems 101 may be coupled to each
other using a network 108.
[0038] The alert originator 102 may be a communications enabled
terminal provided in communication with the messaging subsystem 101
via the network 103. For example, the alert originator 102 may be a
personal computer having a network connection, such as a dial-up
modem connection to a network. In such embodiments, the network 103
may be a packet-switched network such as, for example, the
Internet. In some embodiments, the alert originator 102 may include
an electronic mail application for receiving electronic mail
messages in accordance with, for example, the Simple Mail Transfer
Protocol (SMTP). Further, the alert originator 102 may include a
web browser capable of transmitting and receiving and displaying
information in accordance with the HyperText Transfer Protocol
(HTTP) using the network 103. The alert originator 102 may send a
first message, such as an alert message, to the messaging subsystem
101 via the network 103 in the form of an electronic message such
as, for example, an SMTP electronic message, an HTML or XML
message, or an SMS message from the wireless device. Further, in an
embodiment the alert originator 102 may be a remote sensor or a
sensor monitoring device or system that automatically generates a
message to the messaging subsystem 101 in response to the
occurrence of a conditional event (e.g., flood gates opened at a
dam). In an embodiment, a message or alert generated by a remote
alert originator 102 (including, for example, an automated
process), the alert originator 102 may provide an identifier (e.g.,
for authentication), the intended target recipients of the
message/alert, and the content of the message/alert. In an
embodiment, the originator identification may be provided in the
form of a Personal Identification Number (PIN) code. In at least
one embodiment, the messaging subsystem 101 may only provide
messaging for authorized senders or alert originators 102.
[0039] In an embodiment, the communication gateway 104 may be an
access point for a communication network 107 that provides
communication services for a plurality of user terminals 105. For
example, the communication network 107 may be a landline based
network such as the Public Switched Telecommunications Network
(PSTN). In an embodiment, the network 107 may be a wireless
telecommunications network such as a cellular service provider or a
Personal Communications Services (PCS) service provider. Such
networks 107 may be, for example, but not limited to, based on the
Global System for Mobile Communications (GSM), Code Division
Multiple Access (CDMA) such as the system described in Interim
Standard (IS)-95 for digital cellular radio systems, IS-54 dual
mode analog and digital cellular telephone service, IS-54B digital
Time Division Multiple Access (TDMA) cellular telephone service,
IS-41 based Advanced Mobile Phone Service (AMPS, or "analog")
telephone service, IS-136 Digital AMPS telephone service, or other
standards-based telecommunication system, paging networks,
Blackberry.TM. networks, or a variation or combination thereof.
[0040] The networks 107 may include a control channel, a channel
for data traffic, or both, separate and distinct from the voice
traffic bearing channel or channels. For example, the GSM series of
standards includes a Short Message Service (SMS) channel useful for
sending text based messages. Furthermore, telecommunications
services providers commonly utilize out-of-band signaling, such as
the signaling based on Signaling System No. 7 (SS7), in order to
maximize the voice traffic capacity and availability of the bearer
channel. Other telecommunications services standards include
separate channels for slow signaling or for data-only traffic. In
all such schemes, the data or control traffic may be routed and
transferred throughout the network 107 using communication channels
that are separate from voice traffic channels. Such arrangements
may prevent data traffic from adversely impacting the voice traffic
capacity of the network 107. The inventors of the present invention
have discovered that this separation of data/control channels from
voice traffic channels may have advantages for reliably and quickly
transmitting and receiving text messages via the data or control
channels in situations in which voice channels or circuits are
overloaded, overutilized, or otherwise unavailable to a user. Thus,
embodiments may allow messages to be delivered to first responders,
coordinators, and other emergency response personnel reliably and
quickly, preventing loss of life and property.
[0041] In at least one embodiment, the terminal 105 may be a
cellular telephone, a Personal Digital Assistant (PDA), a Personal
Computer (PC) such as a PC workstation, mobile PC or laptop PC, or
a tablet PC, a Blackberry.TM. device, a pager, a Wi-Fi device, a
Bluetooth.TM. enabled device, a radio receiver, or any other such
wireless or wired terminal capable of receiving non-voice
communications. In an embodiment, the terminal 105 may include a
text message application for receiving and displaying non-voice
messages using a display on the terminal 105 via the network 107.
Alternatively, the terminal 105 may be coupled to a remote output
device for output of a non-voice message for review by a user of
the terminal 105. In some embodiments, the terminal 105 may include
an electronic mail application for receiving electronic mail
messages in accordance with, for example, the Post Office Protocol
(POP/POP3).
[0042] Still further, the terminal 105 may include a web browser
capable of transmitting and receiving and displaying information in
accordance with the HyperText Transfer Protocol (HTTP) using the
network 107. In at least one embodiment, the user terminal 105 may
be, for example, a web-enabled personal computer provided with the
capability to receive and display graphical user interfaces
included on, for example, HyperText Markup Language (HTML)
formatted or Extensible HyperText Markup Language (XML) formatted
pages, private network (e.g., intranet) pages, etc., provided in
accordance with, for example, HyperText Transport Protocol (HTTP)
as well as the capability to transmit and receive electronic mail
messages in accordance with Simple Mail Transport Protocol (SMTP).
In at least one embodiment, the terminal 105 may be in general any
device capable of receiving electronic mail ("email") or paging
messages such as pagers, cell phones, PDAs, and the like. For
pagers, the messaging subsystem 101 may support many different
paging protocols such as, for example, but not limited to, Wireless
Communication Transport Protocol (WCTP), Post Office Code
Standardisation Advisory Group (POCSAG) (various baud rates),
Flexible wide-area synchronous protocol (FLEX.TM.), Golay
sequential coding, Telocator Alphanumeric Protocol (TAP) (e.g.,
version 1.8), and COMP (COMP1 and COMP2). Furthermore, the
messaging subsystem 101 may support delivery of messages to
terminals 105 configured to accept and output instant messages. For
example, the messaging subsystem 101 may support terminals 105 that
use a popup message output such as the WiredRed instant messaging
protocol using WiredRed Software of San Diego, Calif., or the
Computer Emergency Notification System (CENS) used by, for example,
the United States Department of Agriculture (USDA), further
information regarding which is available from the USDA National
Information Technology Center of Washington, D.C. Still further,
the terminal 105 may be another device or system capable of
displaying message or alert information such'as, for example, but
not limited to, an electronic highway sign, AMBER alert sign. In
addition, the terminal 105 may be or include a siren or other
device capable of providing an audible or visual output in response
to receiving a message or alert from the messaging subsystem 101.
Further, the messaging subsystem 101 may re-send messages or alerts
to other systems (e.g, external to system 100) for distribution to
users or other systems. This is not an exhaustive list of the
terminals 105 for which the messaging subsystem 101 may be
configured to support for messaging, but is provided herein as an
example of the breadth of output means supported for message
delivery by the messaging subsystem. In at least one embodiment,
the messaging subsystem 101 may be configured to output one or more
second messages or alerts to one or more of these terminals 105.
The messaging subsystem 101 may be included in a system 100 that
provides message processing and transfer as described herein.
[0043] In operation, referring to FIG. 1, the messaging subsystem
101 may cause messages, such as the second messages, to be sent to
one or more of the user terminals 105 such as, for example, cell
phones and pagers, via one or more of the gateways 104 using a
non-voice traffic channel of the communication network 107. In at
least one embodiment, a message may be transferred to one or more
terminals 105 using an SMS channel of a GSM based wireless
communication network 107. Furthermore, a message may be
transferred to one or more terminals 105 using a paging network
107. Alternatively, a message may be transferred to one or more
terminals 105 using a control channel of the communication network
107. In an embodiment, the network 106 may be a packet-based
network having a logical termination at the gateway 104. For
example, the network 106 may be a Transmission Control
Protocol/Internet Protocol (TCP/IP) network such as, for example,
the Internet, for which the gateway 104 is a destination IP socket
for receiving non-voice based information, or messages, ultimately
destined for one or more terminals 105 served by the network 107.
Message delivery to the user terminal 105 may be accomplished with
high reliability because the non-voice channel bearing the message
remains available in the event that the voice channel is saturated
or otherwise not accessible for completing a voice call.
[0044] Furthermore, the user terminal 105 may provide a
confirmation to the messaging subsystem 101 via the network 106
signifying that the notification information contained in the
gateway message has been received by particular user terminals 105.
In at least one embodiment, the messaging subsystem 101 may provide
reply tracking as described herein to inform the alert originator
102, as a minimum, of the successful dissemination of a message
such as an alert message. Furthermore, messaging subsystem 101 may
collect the status of individual replies and report the status to
the alert originator 102 to assist emergency personnel in
responding to an emergency or potential emergency situation
[0045] In at least one embodiment, the networks 103, 106, and 108
may be a public network such as the Internet. However,
communications systems used to implement the networks 103, 106, and
108 may include, but are not limited to, telephone landline based
modem or a wireless network such as a cellular digital packet data
(CDPD) network or a wireless local area network (LAN) provided in
accordance with, for example, the IEEE 802.11 standard
[0046] In at least one embodiment, the messaging subsystem 101 may
use the networks 107 of different carriers to deliver text messages
to user terminals 105 including, but not limited to, pagers,
wireless PDAs, cell phones, IP-based phones (e.g., voice over IP),
and satellite phones. In an embodiment, cell phone text message
networks 107 may communicate over the control channel of the
respective cellular networks. As described hereinabove, the control
channel may be a channel separate from the voice channel that
continues to be available for , message traffic when voice channels
are saturated and unavailable to complete voice calls. In an
embodiment, the underutilized control channel may not require a
persistent connection and is also capable of providing reliable
communications under degraded channel situations. When used in
combination with another communication medium such as, for example,
one or more paging networks, cellular text messaging by the
messaging subsystem 101 provide reliable and fast emergency
communication when other means of communication such as, for
example, voice systems, are not available
[0047] In an embodiment, each of the user terminals 105 may be
associated with at least one message group 200 as shown in FIG. 2.
Message groups 200 may include multiple user terminals 105, such
as, for example, the devices 1, 2, 3 through "n" as shown in FIG.
2. Each terminal 105 may be associated with a user. Each group 200
may have at least one defining characteristic. For example, a
message group may include a set of user terminals 105 accessible
using the same Internet domain name (e.g,
user.sub.--1@common_domain.gov). Alternatively, a message group may
include a set of user terminals 105 accessible by a particular
network 107 such as, for example, a particular carrier or wireless
telecommunications service provider (e.g., T-Mobile) as shown in
FIG. 2. Moreover, in an embodiment, a first messaging subsystem 101
may be coupled to at least a second messaging subsystem 101,
wherein the first and second messaging subsystems 101 are
configured to provide message transfers between the user terminals
105 coupled to the first messaging subsystem 101 and associated
with one or more message groups 200, and the user terminals 105
coupled to at least a second messaging subsystem 101 and associated
with one or more second message groups 201. This capability
supports cross-jurisdictional communication and cooperation for
responding to emergencies, because diverse or previously isolated
communications systems may be networked together for message
transfer among the systems.
[0048] Furthermore, user terminals 105 may be categorized according
to response group (not shown). For example, a response group may
include the user terminals 105 associated with individual members
of an emergency response team for a given government agency (e.g.,
the U.S. Secret Service). In at least one embodiment, the messaging
subsystem 101 may maintain status for each user registered user
terminal 105 classifying the user associated with the user terminal
105 as one of an administrator, a manager, and a non-originating
user for the message group. In an embodiment, administrators may
have greater system privileges relative to managers, and managers
may have greater system privileges relative to non-originating
users. For example, in at least one embodiment, an administrator(s)
of an organization may be allowed to build and send an alert
message as an alert originator 102. In an embodiment, the alert
originator 102 may utilize a user terminal 105 to access the
messaging subsystem 101 and to generate an alert message. The
messaging subsystem 101 may include features to assist an
administrator in building an alert such as, for example, but not
limited to, using different colors in the build page (e.g., red
background) to remind the alert originator of the type of alert he
is building (e.g., red for a biological alert). Also, the messaging
subsystem 101 may provide partially completed alert build pages for
particular emergency situations, having predefined fields and
message text, such that the administrator only has to "fill in the
blanks" for additional information, in order to increase the speed
in which an administrator may originate an alert. In at least one
embodiment, the messaging subsystem 101 may provide fully completed
alert message templates. Such completed message templates may
include, for example, but not limited to, predefined message text
and predetermined recipient or user groups. Furthermore, an
administrator may be provided the capability to define the
additional questions posed to an individual user during
registration of the user, in order to collect particular
information useful in assembling an emergency response team in the
case of threat or actual emergency event. For example, a hospital
administrator may wish to collect information identifying employees
having four-wheel-drive vehicle, in case of a snow emergency.
[0049] In an embodiment, users of the system 100 may be classified
according to a variety of criteria for message generation
privileges and varying degrees of system access. For example, a
user of the system 100 may be a sender. A sender may be assigned a
unique PIN for message origination to allow the messaging subsystem
101 to determine that the sender is an authorized sender. A user
may also be a manager, an administrator, or a non-originating user.
An administrator has the highest level of message sending and
information access. For example, an administrator may be provided
access to an interactive page that provides an administrator
console. By interacting with the administrator console, an
administrator may add, change, or delete user or device related
information maintained by the messaging subsystem 101. In an
embodiment, the administrator console page may provide interactive
fields and icons that are not provided to or accessible by other
users. The administrator may also define the access privileges of
other users in a group or particular organization. A manager may be
able send only those messages for which an administrator has
granted send privileges to the sender, in an embodiment, but may
however be permitted to add, delete, or modify user registration
information or device information, or to undertake other
maintenance activities using the messaging subsystem 101. In an
embodiment, managers may also authorize particular users in their
group to be senders. Non-originating users may be able to receive
messages via their associated user terminal(s) 105. Non-originating
users may also be able to access, add, or modify only the
information for themselves. In an embodiment, to de-register, a
non-originating user must obtain permission from a manager or
administrator.
[0050] Further detail regarding the messaging subsystem 101
according to at least one embodiment is shown in FIG. 3. Referring
to FIG. 3, the messaging subsystem 101 may include a message engine
301 which may be coupled to a web server 302, and a user messaging
database 303 which may be coupled to both the message engine 301
and the web server 302. The message engine 301 may further include
a self-contained electronic mail processor 304 configured to, as a
minimum, transfer electronic messages to communication gateways
104. The message engine 301 may include a sequence of programmed
instructions that when executed in cooperation with the web server
302 and the database 303 cause the messaging subsystem 101 to
perform the functions described herein. In at least one embodiment,
the instructions may be implemented in the form of Practical
Extraction and Reporting Language (Perl) script code. Furthermore,
the message sending process may be launched by, for example, a
Hypertext Preprocessor (PHP) as code implemented using Perl scripts
such that the Perl code is executed by a PHP-driven web interface.
Alternatively, the Perl scripts may be implemented as Common
Gateway Interface (CGI) scripts used to transfer information
between the web server 302 and the message engine 301.
Alternatively, the messaging subsystem 101 may be implemented using
instructions provided in accordance with the C/C++, Java.TM., or
Python.TM. programming languages
[0051] In an embodiment, the message engine 301 may be configured
such that multiple different modules (i.e., communication
system/device capabilities) are supported and will interact with
the mail processor 304. Thus, multiple message delivery methods may
be supported and capabilities to support new alert/message target
devices added as needs and communication capabilities evolve. In at
least one embodiment, the user terminals 105 or devices may be
grouped by the message engine 301 by delivery method (e.g.,
communications system) to allow messages or alert messages to be
sent to several devices in a single delivery attempt to minimize
the number of connections (e.g., IP connections) made by the
message engine 301.
[0052] In an embodiment, upon receiving a first message, such as a
first alert message, the message engine 301 may cause a
corresponding second message, such as a second alert message, to be
delivered to one or more user terminals 105. In particular, the
second message may be transferred or broadcast to a large number of
user terminals 105 associated with one or multiple response groups
within a very short period of time. In at least one embodiment, the
time from the first message being initiated by the alert originator
102 to the time that the first of the intended recipient user
terminals 105 receive a corresponding second message or alert via
the network 107 may be within two seconds.
[0053] The message engine 301 may group user terminals 105 by their
carriers to deliver messages to multiple devices in a single
gateway message transmission. By thus transferring messages to
multiple carriers via the communications gateways 104, combined
with the parallel processing of individual carriers, allows the
system 100 to process and submit for delivery messages for tens of
thousands of users in a few seconds. The message engine 301 may
monitor the arrival of the first messages or alert messages through
various arrival methods and interfaces. In case the first message
contains special characters and/or formatting (e.g., multi-media
messages), the message engine 301 may also parse the message
received from the alert originator 102 to extract the actual
textual information and, if necessary, dissect the message into
smaller pieces appropriate to the user terminal 105 (e.g., a mobile
device) memory and display limitations. Thus, in converting the
first message or alert message received from the alert originator
to a gateway message, the message engine 301 may reformat, for each
of the one or more gateway messages, the first message received
from the alert originator 102 to a format in which the
communication gateway 104 associated with the gateway message will
accept and perform operations in response to the incoming gateway
message. Further to the conversion process, the message engine 301
may form an address for each of the one or more gateway messages to
include the domain name information associated with the
communication gateway 104 and the user identification information
(e.g., "username@government_agency.gov") associated with the
registered user receiving the second message. Thus, in an
embodiment, the message engine 301 may reformat and adapt the first
message into a mobile device text message adaptation (i.e., e-mail
dissection).
[0054] Furthermore, in at least one embodiment, in converting the
first message or first alert message to a gateway message, the
message engine 301 may accommodate the text message limitations of
the particular network 107. For some networks 107, the full message
as received from the alert originator; or as originated by an
administrative user via the web server 302, may not fit into a
single text message due to character limits set by the individual
carriers. For example, the Sprint.TM. network supports 100
characters per message. Therefore, in order to receive a
500-character message, a user would need to receive five messages
via the Sprint.TM. network to his user terminal 105. In such a
case, the message engine 301 may dissect the message received from
the alert originator into multiple text messages. The inventors
have discovered an optimal character limit for each device or user
terminal on particular networks 107. The optimal character limit
may be determined based on achieving ease of output for user quick
recognition on a display of the user terminal, as well as for
efficient routing throughout the particular network 107. These
parameters may be stored using the database 303 and retrieved by
the message engine 301 as required for particular gateway alert
messages. For electronic messages (i.e., "e-mail"), the message
engine 301 may further include the sender, subject and the text in
the body of the e-mail message transferred to the communication
gateway 104. The message engine 301 thus enables message
originators to focus on the content of their message and not the
final format for delivery to specific mobile devices.
[0055] In addition, in an embodiment, the message engine 301 may
parse or strip all or a portion of the header and message content
of the first message as received from the alert originator 102
based on the message parameters required by the network 107 for the
type of message to be delivered. Such parsing may include sending
only the actual textual part of the e-mail, stripping out possible
headers, HTML code, or cc'ed address information. Thus, the message
engine 301 may associate a unique set of message parameters with
each of the communication gateways 104. The messaging subsystem may
then transmit a gateway message or gateway alert message to one or
more of the user terminals 105 via one or more of the communication
gateways 104 in accordance with the set of the unique message
parameters for each communication gateway 104, in response to
receiving an alert message or first message from the alert
originator 102.
[0056] The message engine 301 may also provide the capability for
non-originating users to be organized into administrator defined
alert groups. The message engine 301 may then be configured by an
administrator to send alert messages to one or more of the alert
groups, thereby allowing for communication to specified subsets of
users depending on the nature of the message. An example of a group
membership interactive page 400 provided in at least one embodiment
is shown in FIG. 4. Referring to FIG. 4, non-members 401 may
display a list of all registered users on the system. Members 402
may display a list of all registered users who are members of the
particular group. An Administrator can select any number of
non-members and click "Add" to make them members of the group.
[0057] Furthermore, users in one alert group served by a first
messaging subsystem 101 may exchange alert messages with the users
of a remote alert group served by another messaging subsystem 101.
In an embodiment, remote groups (i.e., groups set up by
administrators of other messaging subsystems 101) may be displayed
(or otherwise output) to a user as regular local groups in the send
alert user interface. FIG. 5 depicts a Graphical User Interface
(GUI) for configuring remote user messaging groups in at least one
embodiment. Referring to FIG. 5, the form field Group Name 501 may
be the name of the group to be created. The form field Short Group
Name 502 may be an abbreviated name for the group to be created.
The form field Group Code 503 may assign a code to the group to be
created. The form field Remote Server 504 may designate the server
on which the remote group is stored.
[0058] In at least one embodiment, users can have multiple devices
(i.e., multiple user terminals 105) each having the capability to
receive messages from the messaging subsystem 101. For example,
each user terminal 105 may have e-mail access to the same or
different networks 107. This diversity provides for redundancy over
different carriers and infrastructures to increase the probability
of successful delivery of a message to a user.
[0059] Furthermore, the message engine 301 may track the
confirmation or other response received back from the user via the
user terminal 105 in real-time in order to collect and maintain the
status of user responses to alert messages and lists users that
have not responded as well as providing information on
bounced/undeliverable messages or out of office replies. A GUI
including an alert tracking interactive page 600 provided in an
embodiment is shown in FIG. 6. Referring to FIG. 6, the "Alert #"
field 601 may display a unique numeric identifier for a particular
alert message. The "Groups" field 602 may show the name of each
group of users a sender has assigned to receive the alert message.
The "To" field 603 may display a graphical icon for each delivery
channel or "device type" a sender has selected to receive the alert
message. The "#" field 604 may show the number of users who
received the alert message. The "Responses Confirmed" field 605 may
display the number of users who have responded to the alert
message. The "Responses Other" field 606 may display the number of
replies to a message that are not confirmed as valid responses from
users, e.g. invalid message recipient replies or "bounce-backs",
"out of office" replies and other such responses
[0060] In at least one embodiment, the messaging subsystem 101 may
be deployed as a standalone server solution with no software to
install on other servers, user's client computers, or mobile
devices. Alternatively, the messaging subsystem 101 may be
implemented as an Application Service Provider (ASP) based service
hosted separately from the user organization's existing systems and
accessible via a network such as the Internet. In an embodiment,
the messaging subsystem 101 may be implemented using, for example,
open source operating system software such as Linux. In an
embodiment, the user messaging database 303 may be a Structured
Query Language (SQL) database. In at least one embodiment, the
messaging subsystem 101 may be based on the Linux operating system.
Alternatively, the messaging subsystem 101 may be based on
Microsoft Windows.TM. NT/XP.TM., Sun Solaris.TM., or Open BSD.TM.
Unix.TM. provided by Berkeley Standard Design, Inc. of Berkeley,
Calif.
[0061] Users may access the system 100 via, for example, a
packet-based network such as the World Wide Web. In at least one
embodiment, the web server 302 may provide a web interface by which
users may subscribe, enter, and manage information specific to
their user terminals 105 or mobile device(s) and/or e-mail
accounts. In particular, the messaging subsystem 101 may be setup
entirely by an administrator to centralize the initial registration
process (as described herein). Furthermore, in an embodiment, users
of all levels may be provided the capability to register
themselves, thereby relieving the administrative burden on the user
organization.
[0062] In at least one embodiment, the web server 302 may provide
the interface between the user and the system 100 to collect and
display information related to messaging subsystem 101 accounts and
operational settings. Referring to FIG. 3, the web server 302 may
further include a user web section 305 and an administrator web
section 306. The user web section 305 may include a sequence of
programmed instructions that configure the web server 302 to allow
users to sign up for an account, or register, and enter their
device or user terminal 105 information. For example, a registering
user may enter her cell phone number and carrier (or wireless
device/e-mail address). Users with existing accounts may access a
"MyService" account page provided for the purpose of, for example,
allowing users to modify their profile and terminal 105
information, send alerts if they are authorized users, and access
the online help via the FAQs and help pages. Furthermore, the user
web section 305 may allows users to set up multiple devices
including e-mail addresses for alert deliveries. For example, a
user may select his cell phone, work e-mail, home e-mail, and his
spouse's cell phone, pager, and work e-mail. In at least one
embodiment, a user may send a self test message to all of his
selected devices. By entering the necessary access information for
each of these user terminals 105 associated with the user, the
system 100 will provide an alert message to each such user terminal
105 associated with the user for messages or alerts intended for
receipt by that user.
[0063] The administrator web section 306 may allow users having
administrator level access authorization (e.g., "administrators")
to send alerts or messages, view and modify all account
information, create and assign membership to groups, modify system
settings, view usage and summary statistics, produce reports, and
backup the messaging subsystem data. Administrators may enter new
users and modify their information allowing for setup and use of
the system 100 without any end user involvement. Administrators may
send messages or alert messages to one or more groups. Further, the
administrator web section 306 provides an advanced group sending
capability that allows members of one or more groups that are not
members of other particular groups to receive messages. This is
useful for situations in which a user is a member of several groups
and the same message is sent to each of those different groups over
time. Thus, the advanced group sending capability eliminates
duplicate messages going to the same recipient.
[0064] In at least one embodiment, the web server 302 may provide
detailed logging of all messages. The web server 302 may also
provide a report generation capability for rendering and outputting
to a requesting administrative user an indication of all previous
alert messages along with alert source, date, time, and delivery
information. Further, the web server 302 may also provide response
logs for rendering and outputting to a requesting administrative
user real-time information to track the replies that users send in
response to receiving the second messages, thus providing true
receipt status. This response log information may include an
indication of particular users that have not responded as well as
devices or user terminals 105 that have bounced (i.e., not accepted
the message) or for which messages are undeliverable. Furthermore,
in an embodiment, the web server 302 may include a tool to create a
group on the fly allows administrators to quickly send a message to
users that have not responded, for example. Secure Socket Layer
(SSL) security may be optionally provided to ensure privacy during
connections to the web server 302. In at least one embodiment, the
web server 302 may be based on the open source Apache Web Server
originally developed by the Apache Group, the source code for which
is publicly available from various sources including the World Wide
Web. Alternatively, the web server 302 may be implemented using the
Microsoft Internet Information Server (IIS.TM.) for Windows NT
platforms. In at least one embodiment, the database 303 may include
a preprocessor such as, for example, the open source, server side
Hypertext Preprocesser (PHP), for creating dynamic World Wide Web
pages. PHP scripts are compatible with many database systems.
[0065] The user messaging database 303 may be used to store message
and user account information for the system 100. Upon user request,
information contained in the database 303 may be retrieved and
provided to the web server 302 for rendering and outputting to the
requesting user using, for example, an HTTP interface to the web
server 302. Furthermore, the message engine 301 may obtain
information stored in the database 303 to prepare and deliver
messages to the user terminals 105 via gateway message sent to the
communication gateways 104.
[0066] In an embodiment, the user messaging database 303 may
include a database management system (DBMS) software application
such as the MySQL.RTM. open source Relational Database Management
System (RDBMS) available from MySQL AB of Sweden, the source code
for which is publicly available from various sources including the
World Wide Web, for storage and retrieval of, for example, user
account or message format data in accordance with the Structured
Query Language (SQL) database format. Alternatively, the database
303 may be implemented using SQL Server 7.0 provided by Microsoft
Corporation, or similar products provided by Oracle.RTM. Corp. of
Redwood Shores, Calif. or the open source PostgreSQL
[0067] In one embodiment, the database 303 may execute a sequence
of SQL scripts operative to store or retrieve particular items
arranged and formatted in accordance with a set of formatting
instructions. For instance, the database 303 may execute one or
more SQL scripts in response to a request from the web server 302
to receive particular items of user account information in a format
suitable for transmission to and display by the user terminal 105
using a web browser software application such as, for example,
Internet Explorer.TM. provided by Microsoft Corporation. In one
embodiment, the database 303 may communicate with the web server
302 and the message engine 301 in accordance with the Open Database
Connectivity (ODBC) standard developed by Microsoft
Corporation.
[0068] Further, the web server 302 may be used in an embodiment to
generate and transmit interactive HTML or XML pages to the alert
originator 102 via the network 103 and to the user terminal 105 via
the networks 106 and 107. In particular, the web server 303 may
receive requests for information as well as user entered data from
the alert originator 102 or the user terminal 105. Such user
provided requests and data may be received in the form of user
entered data contained in an interactive HTML or XML page provided
in accordance with the Java Server Pages.TM. standard developed by
Sun.TM. Microsystems. Alternatively, user provided requests and
data may be received in the form of user entered data contained in
an interactive HTML or XML page provided in accordance with the
Active Server Pages (ASP) standard. In response to a user entered
request, the web server 302 may generate a report in the form of an
interactive HTML or XML page by obtaining user and alert data,
which may include alert tracking date, corresponding to the user
request by transmitting a corresponding command to the database 303
requesting retrieval of the associated data. The database 303 may
then execute one or more scripts to obtain the desired information
and provide the retrieved data to the web server 302. Upon receipt
of the requested data, the web server 302 may build an interactive
HTML or XML page including the requested data and transmit the page
to the requestor in accordance with, for example, HTML and Java
Server Pages.TM. (JSP) formatting standards.
[0069] In an embodiment, the messaging subsystem may further
include a firewall (not shown) to protect the system 100 against
unauthorized access. The firewall functions to exclude unknown or
unauthorized users from accessing the 100.
[0070] The message engine 301, web server 302, and user messaging
database 303 may be implemented in the form of application software
executing on at least one computing platform. FIG. 7 is a
functional block diagram of one embodiment of a computing platform
400 useful for hosting software application programs implementing
the message engine 301, web server 302, and user messaging database
303. Referring now to FIG. 7, the computing platform 700 includes a
processor 705, a network interface 710, a user interface 720,
operating system instructions 735, application executable
instructions/API 740, all provided in functional communication
using a data bus 750. The processor 705 may be any microprocessor
or microcontroller configured to execute software instructions
implementing the functions described herein. Application executable
instructions/APIs 740 and operating system instructions 735 are
stored using computing platform 700 nonvolatile memory. Application
executable instructions/APIs 740 include software application
programs implementing the message engine. 301, web server 302, and
user messaging database 303. Operating system instructions 735
include software instructions operable to control basic operation
and control of the processor 705. In one embodiment, operating
system instructions 735 may include the NT.TM. operating system
available from Microsoft Corporation of Redmond, Wash. In at least
one embodiment, the computing platform may be a PC provided by Dell
Computer of Round Rock, Tex.
[0071] As described previously, the message engine 301, web server
302, and user messaging database 303 may each reside on a single
computing platform 700, or on more than one computing platform 700,
or each application may reside on a separate computing platform
700. In an embodiment, the messaging subsystem 101 may be scaleable
such that additional message engines 301, web servers 302, and user
messaging databases 303 may be added to the messaging subsystem 101
as required to increase message transfer speed or to maintain
system 100 capabilities as subscribers to the service increase.
Application executable instructions/APIs 740 and operating system
instructions 735 are loaded into one or more allocated code
segments of computing platform 700 volatile memory for runtime
execution. In one embodiment, computing platform 700 includes 256
MB of volatile memory and 20 GB of nonvolatile memory storage.
[0072] Application executable instructions/APIs 740 may include one
or more application program interfaces (APIs). The messaging
subsystem 101 application programs may use APIs for inter-process
communication and to request and return inter-application function
calls. For example, an API may be provided in conjunction with the
database 303 in order to facilitate the development of SQL scripts
useful to cause database 303 to perform particular data storage or
retrieval operations in accordance with the instructions specified
in the script(s). In general, APIs may be used to facilitate
development of application programs which are programmed to
accomplish the messaging functions described herein, such as the
addition of new communication modules and integration with third
party products.
[0073] Returning to FIG. 7, the network interface 710 may provide
the computing platform 700 the capability to transmit and receive
information over the Internet, including but not limited to
electronic mail, HTML, or XML pages, and file transfer
capabilities. To this end, the network interface 710 may further
include a web browser such as, but not limited to, Microsoft
Internet Explorer.TM. provided by Microsoft Corporation. The user
interface 720 may include a computer terminal display, keyboard,
and mouse device. One or more Graphical User Interfaces (GUIs) also
may be included to provide for display and manipulation of data
contained in interactive HTML or XML pages.
[0074] Thus, the system 100 may provide a solution for emergency
alert notification. In particular, the messaging subsystem 101 may
be device and carrier agnostic, adhering to applicable Internet and
wireless standards to allow the messaging subsystem 101 to work
with existing carriers and equipment. Furthermore, the system 100
provides reliable and fast message delivery, simple web-browser
based management, networking capabilities for forming coalitions
between multiple messaging subsystems 101, and easy interfacing
with existing emergency-management infrastructure. For example, a
first messaging subsystem 101 may be coupled to a second, third,
etc. message processing system 101 using, a network 108 for example
as shown in FIG. 1, to allow messages to be shared between diverse
users and groups served by any particular messaging subsystem 101.
This permits, for example, an alert message originating from the
Department of Energy and received at a first messaging subsystem
101 to be shared with a member of a local government fire and
rescue team via a second messaging subsystem 101. This capability
permits interoperability among different organizations and
agencies, thereby improving inter-jurisdictional coordination among
agencies at various levels of government. in effectively responding
to an emergency. Thus, emergency response personnel are provided
with flexible and powerful message (e.g., alert message)
distribution within and across organizational boundaries. Finally,
by utilizing certain aspects of existing technologies and
infrastructure that most companies and organizations already have
in place, the system 100 provides for fast, incremental, and
cost-effective installation.
[0075] Furthermore, the system 100 may include, in at least one
embodiment, certain capabilities that further serve to improve the
ability of users to communicate effectively. For example, the
system 100 provides very high reliability due to, for example,
redundancy of delivery channels to multiple user terminals 105. In
an embodiment, use of a non-voice channel to transfer messages to
user terminals 105 also provides increased reliability with respect
to voice-based systems and methods. In fact, the messaging
subsystem 101 is in many cases able to continue to function
effectively when other communication methods have failed. By
sending messages to all mobile devices and e-mail boxes registered
for each user, the likelihood of successful message delivery to the
user by at least one of the redundant communication channels is
high. Further, because most of these channels are disjoint any
outage on one will not affect delivery through the others.
[0076] Still further, the messaging subsystem 101 may be made
redundant across several servers to provide for service with
reduced points of failure. The features of the messaging subsystem
and design may ensure that the alert message is received,
processed, and delivered to the users at their defined devices.
Once users are registered with the system, the messaging subsystem
simplifies the alert originator's task in drafting the emergency
alert. The messaging subsystem may handle packaging the message and
ensuring it is delivered in the best legible format appropriate for
the users' device(s).
[0077] in addition, the system 100 may deliver messages very
quickly to user terminals 105, thus increasing response time and
response force for an emergency response team. Emergency messages,
for example, are usually time-critical. The system 100 may be able
to deliver messages to thousands of recipients within a few
seconds.
[0078] Furthermore, in an embodiment, users of the system 100 do
not need to substantially modify their existing routines to
implement the system 100. The messaging subsystem 101 may be
implemented by a new user without adding new system interfaces, for
example. In addition, the messaging subsystem 101 may be
implemented in conformance with industry standards and equipment.
In at least one embodiment, the messaging subsystem 101 may be
implemented using open source software components. Therefore, the
system 100 is not intrusive to the user's existing systems and does
not require retrofitting or software modification of existing
systems. The messaging subsystem 101 may be able to be used with
standards based or proprietary existing systems. Thus, the
messaging subsystem 101 may be added even for situations in which
the installation of any integration software is not feasible.
However, these same characteristics allow the messaging subsystem
101 to be integrated with existing alert initiation technology for
users that already have systems in place that monitor events and
trigger alerts accordingly.
[0079] Furthermore, the system 100 may include plug-and-play
installation functionality with existing systems. In particular,
the system 100 may be a server-based solution that may be delivered
and installed as a network appliance. In an embodiment, few steps
are required to deploy the system 100. For example, adding a
messaging subsystem 101 capability may be accomplished by: 1)
Connect the box into the network; 2) Assign an internal or publicly
available name to the system for easy web browser access; and, 3)
Either establish two external e-mail boxes or modify Domain Name
Server (DNS) MX entries to direct SMTP traffic for any specific
domain into the messaging subsystem box. The last step may be a
quick customization of the system through the administrative
console. DNS MX records identify the mail server(s) responsible for
handling electronic mail for a domain name.
[0080] In an embodiment, the system 100 may provide high data
integrity and accuracy. For example, by allowing users to
self-register, data integrity is increased because at least one
step in database population or registration of users is eliminated.
For example, registering users do not have to first enter their
contact, etc. information onto a standard form for later data entry
by clerical personnel. Furthermore, because users can enter their
information directly, the system 100 may provide for relatively
easier maintenance for both users and administrators in maintaining
the consistency of the database. Furthermore, the system 100 may
provide user friendly initial user registration. In particular, to
register, a user may provide basic information such as his or her
name, e-mail address and optionally one or more mobile devices, and
this may be the only step each user has to take to register and
participate in the system 100. In an embodiment, no changes to any
other setup, no installation of additional software or periodical
maintenance is required. An example of a registration interactive
page 800 provided in at least one embodiment is shown in FIGS. 8a
and 8b. Referring to FIG. 8a, the form fields Name and Email
Address 801 may be for the user's name and email address. The email
address uniquely identifies the user in the database. The form
field Cell Phone/Mobile Device Carrier 802 may allow the user to
select a carrier or device identifier for each device registered.
The form field Password 803 may allow the user to create a password
to protect the account. Referring to FIG. 8b, the field 804 may be
an example of a Supplemental Information question. An Administrator
may add any number of these questions to the registration process
through the Administrator Console (See FIG. 10). A user's response
to these questions may trigger secondary questions designed to
capture more information about each individual user during the
registration process.
[0081] Further, message and user information may be shared among
multiple organizations that may be served by a different one of
multiple messaging subsystems 101. For example, some emergencies
cross boundaries of jurisdictions and thus neighboring or otherwise
related organizations may need to be included on some alert
messages. In at least one embodiment, the system 100 may allow
different users to form a grid of messaging subsystem 101
deployments for cross jurisdictional alert messaging and emergency
management. An example of a grid 900 according to at least one
embodiment is shown in FIG. 9. Referring to FIG. 9, therein is
depicted an exemplary system 100 for The Metropolitan Washington
Council of Governments ("COG") deployment. COG is a regional
organization of Washington, DC area local governments, plus area
members of the Maryland and Virginia legislatures, the U.S. Senate,
and the U.S. House of Representatives. COG provides a focus for
action and develops regional responses to issues such as the
environment, economic development, public safety, transportation
and regional coordination for major disasters. Fairfax County 901
is one of the COG member jurisdictions. In this example, Fairfax
County can use the system 100 to send messages to user groups 901
from any of the other jurisdictions shown on the map using Remote
Groups features (See FIG. 5).
[0082] Still further, in at least one embodiment, the system 100
provides for multiple ways for alert origination as described
herein. For example, an alert originator 102 may send an alert
message, or first message, to the messaging subsystem 101 by
HTML-formatted web page including alert originator added data in
accordance with the HTTP protocol, by SMTP-formatted electronic
mail message, by SMS-formatted text message, by eXtensible Markup
Language (XML) formatted message, by Instant Message (IM.TM.)
provided by, for example, America Online.TM. of Dulles, Va., and by
Short Message Service (SMS) for GSM-based networks, or from any
e-mail enabled device (e.g., any e-mail client, 2-way pager, cell
phone, etc.). By thus allowing authorized senders to originate an
alert in various situations, multiple ways to submit alerts are
provided.
[0083] In addition, the system 100 may provide instant delivery to
carrier networks. For example, the messaging subsystem 101 may, for
each alert message, organize devices by carrier, and then transfer
to each carrier via communication gateway 104 only one gateway
alert message with all the target devices listed within this
message. This multicasting speeds up the message processing time
within the system 100 significantly.
[0084] Still further, the system 100 may include a simple
management console that provides a straightforward yet powerful
administrator console that allows authorized personnel to add,
remove and modify user and device information and to form groups of
individual users and authorize specific users to post alerts to
defined groups. Administrators as well as authorized users can post
messages to groups and/or individual users and review alert logs as
well as response logs. Also, follow-up messages can be sent to
non-responders, users who responded in a certain way, or any other
arbitrary groups of users. In an embodiment, the home page may be a
"send alert" page. An example of a management console interactive
page 1000 provided in accordance with at least one embodiment is
shown in FIG. 10. Referring to FIG. 10, Quick Alerts 1001 may be
graphical icons that when clicked load pre-formatted alert
templates and content. For example, when an Administrator or
authorized sender clicks the "EVAC" icon, a preformatted alert
loads automatically, saving the sender the time it would take to
type the text, select the groups of recipients and configure the
various sending options. The text might say, "Exit the West Office
Building immediately." Or, if the message is a follow-up, "The West
Office Building is now safe and secure. You may return." The sender
need only click the "Send" button to send the message to
pre-selected groups and devices. This process is illustrated in
FIG. 14. Referring to FIG. 14, there is also shown an example of a
received alert message on the display of a mobile telephone
handset. Returning to FIG. 10, the Alert Category 1002 may allow
the user to select a predefined alert type, so that the "from"
address of the alert and potentially the source of the alert are
automatically configured. The Send to Members Of 1003 may allow a
sender to select individual user groups to be recipients of the
alert message.
[0085] In addition, the messaging subsystem 101 may provide a
report generator for producing one or more reports that include
statistics and charts showing the distribution of types of user
terminals and communication media or channels. Such reports may be
provided in response to receiving a corresponding request from an
administrator user using the administrator console. Example
interactive report pages 1100 provided in at least one embodiment
are shown in FIGS. 11a and 11b. Referring to FIG. 11a, the System
Summary 1101 may output a number of system statistics
Administrators find useful to track. System Management 1102 may
output a list of downloadable reports, hyperlinks to their
corresponding files in at least two formats and a hyperlink to
download a full system backup file. The Group Distribution section
1103 may output information regarding all user messaging groups. An
interactive report page 1100 illustrating an example carrier
distribution report 1103 is shown in FIG. 11b. Referring to FIG.
11b, the carrier distribution report 1103 may include information
in numeric and visual form such as, for example, a pie chart,
showing the relative distribution of communications carriers used
for sending one or more messages.
[0086] Furthermore, the messaging subsystem 101 may provide systems
and methods for reply tracking including, but not limited to:
[0087] an alert tracker page,
[0088] a summary of log messages,
[0089] message log detail,

[0135] Furthermore, the messaging subsystem 101 may provide systems
and methods for user management including, but not limited to:
[0136] the ability to edit personal account information (e.g., edit
an email account, address, school; unsubscribe; and choose an alert
device to receive alerts),
[0137] the ability to self subscribe to alert types and groups,

and methods for other miscellaneous functions including, but not
limited to:
[0155] an alert incident page that may be edited for look and feel
for the incident,
[0156] providing an incident page link in the alert messages.
[0157] A method 1200 according to at least one embodiment is shown
in the flow chart of FIG. 12. Referring to FIG. 12, a method 1200
may commence at 1205 and proceed to 1210, at which a method may
include registering a plurality of users to receive messages from
at least one alert originator. Control may then proceed to 1215, at
which a method may enter a state awaiting reception of an alert
message from an alert originator. Upon receiving an alert message
from an alert originator, control may proceed to 1220 in which a
method may include determining a set of user terminals to receive a
user alert message corresponding to the received alert message. In
at least one embodiment, the set of user terminals may be
associated with the registered users of at least one message
recipient group.
[0158] Control may then proceed to 1225, in which a method may
include converting the alert message to one or more gateway alert
messages. Alternatively, for SMS received alert messages,
conversion at 1225 may be bypassed and the SMS message output as a
gateway alert message. In an embodiment, this may be accomplished
by transferring the first message received from an alert originator
to an SMS or priority gateway for distribution of the SMS message
to user terminals. An example of an SMS gateway is the Bunny
Hop.TM. Short Message Servicing Center (SMSC) product provided by
TeleCommunications Systems, Inc. of Annapolis, Md. In either case,
control may then proceed to 1230, at which a method may
conditionally determine whether or not another gateway alert
message is to be prepared. If so, control may return to 1225 for
conversion. If not (e.g., there are no more gateway alert messages
to be prepared), control may then proceed to 1235. At 1235, a
method may include transferring each of the gateway alert messages
to its corresponding communication gateway. Control may then
proceed to 1240, at which a method may include distributing or
delivering an alert message by the communication gateways, upon
their receiving a gateway alert message, to each of the registered
users associated with the at least one message group. In at least
one embodiment, the transfer may be performed using a non-voice
channel of the communication network. Control may then proceed to
1245, at which a method may include tracking replies received from
each user in response to the alert message(s) received by the user.
Control may then proceed to 1250, at which a method may end
[0159] Further detail regarding registration of users per 1210 is
shown in FIG. 13. Referring now to FIG. 13, registration 1210 in at
least one embodiment, may further commence at 1305 and proceed to
1310, at which registration may include associating each registered
user with a user terminal. Further, control may also proceed to
1325, at which an administrator may define and add additional
questions designed to obtain particular information from users
during the registration process. Control may then proceed to 1315,
at which a registration method may include conditionally
determining whether another user terminal should be associated with
the user. If so, then control may return to 1310. If not (i.e., no
further user terminals to be associated with the user), then
control may proceed to 1320. At 1320, the registration method may
include categorizing the user. In at least one embodiment, the
registering user may be registered as one of an administrator, a
manager, or a non-originating user Control may then proceed to
1330, at which a registration method may include collecting
information from the registering user. In an embodiment, user
information may be collected using an interactive page such as, for
example, a World Wide Web page, which includes data fields in which
the registering user may enter information in response to
corresponding questions provided on the page. In an embodiment, the
questions on the registration page may be previously defined by an
administrative user. The user provided information may then be
stored in a database, at 1335. Control may then proceed to 1340, at
which a registration method may. end. An illustration of an example
registration page 800 provided in conjunction with registration
1210 is shown in FIGS. 8a and 8b.
[0160] Further detail regarding determining a set of receiving user
terminals per 1220 is shown in FIG. 15. Referring to FIG. 14,
determining a set of receiving user terminals may, in at least one
embodiment, commence at 1505 and proceed to 1510. At 1510, a
determining method may include analyzing the collected user
information for the presence of one or more particular
informational items based on criteria selected by the alert
originator. For example, an alert originator may wish to send an
alert message to all registered users in a group that speak
Spanish. During registration, the capability may be provided for
the user to specify in which language(s) she wants to receive
messages on her devices. Further, the user may specify during
registration the language in which he wishes to interact with the
registration page and enter user information. Control may then
proceed to 1515, at which a determining method may include
selecting the group of user terminals based on the users associated
with the user terminals whose user information matches the criteria
specified in the analyzing (for example, users whose information
indicates that he speaks Spanish). Control may then proceed to
1520, at which a determination method may end.
[0161] Further detail regarding converting an alert message to a
gateway alert message per 1225 is shown in FIG. 16. Referring to
FIG. 16, converting a message to a gateway alert message may, in at
least one embodiment, commence at 1605 and proceed to 1610. At
1610, a converting method may include retrieving parameters from a
database that are associated with the communication gateway to
which the gateway alert message is intended. Such parameters may
include the maximum word length, header information, routing
information, and other information particular to the communication
gateway and its network. In at least one embodiment, the database
303 may include an optimum number of characters for the message
based on the memory and display capacity of the user terminal 105.
For example, a message destined for a wireless terminal such as a
cell phone handset with a Liquid Crystal Display (LCD) may be
limited to 40 characters maximum. Furthermore, the information may
include a specification of the maximum number of characters for the
gateway alert message specifically chosen for maximum likelihood of
message delivery by the network 107 to the user terminal 105 based
on, for example, historical data characterizing network traffic
reliability. Control may then proceed to 1615, at which the
converting method may include reformatting the received alert
message (for each gateway alert message to be provided), the alert
message received from the alert originator to a format in which the
communication gateway associated with the gateway alert message
will accept and perform operations in response to the incoming
gateway alert message. Control may then proceed to 1620, at which a
converting method may include forming an address for each of the
gateway alert messages to include the domain name information
associated with the communication gateway and the user
identification information associated with the registered user
receiving the alert message (e.g., user name@verizon.net). In at
least one embodiment, forming an address may also include forming a
pager address by entering a ten digit telephone number. In an
embodiment, forming an address may include appending a suffix to an
electronic mail address or IP socket that specifies a fast route
through the network 107, for increased speed in alert message
delivery to user terminals 105. For example, the address suffix may
specify a particular access point or IP socket within the network
107 bypassing one or more routing points in the network 107, for
faster message routing and delivery. During registration, the user
may also be prompted to enter the identifier for his device. The
user's entry may be validated by the system, and if the entered
number does not match an expected format (stored using a database
303), the messaging subsystem 101 may select the associated
carrier's standard prefix and suffix. If this results in a valid
address, then this address is used by the system. If not, the user
may be prompted to edit his entry. If necessary, the messaging
subsystem 101 may also append a prefix to the device access number
(e.g., "<prefix>.<cell phone number>@<domain
name>"). Control may then proceed to 1625, at which the
converting method may include determining if another gateway alert
message is to be prepared. If so, control may return to 1610. If
not, then control may proceed to 1630, at which a converting method
may end. Because the networks 107, user terminals 105, and
communication gateways 104 may be different, any one of the gateway
alert messages may be formatted differently than one or more other
gateway alert message. An example GUI interactive delivery channels
page 1700 which may be used to configure delivery channel settings
is shown in FIG. 17. These settings are automatically applied to a
device based on the carrier a user chooses when creating it, such
as during registration 802. Referring to FIG. 17, Delivery Channel
Name 1301 may output the name assigned to the delivery channel.
Character Limit Per Message 1302 may output the number of
characters for that delivery channel, beyond which a message must
be sent in multiple parts. Delivery Method 1303 may output the
protocol used to deliver a message to this delivery channel.
Automatic Prefix 1304 may output any information that must be added
in front of a delivery channel address. Automatic Suffix 1305 may
output the delivery channel address suffix. Class 1306 may output
the channel type, e.g. email, cell phone, pager, desktop alerts,
instant message, SMS, etc. Comment 1307 may output any pertinent
information an Administrator wishes to add.
[0162] Furthermore, the transferring of gateway alert messages may
also include prioritizing the order in which each gateway alert
message is transferred according to communication gateway
characteristics. In an embodiment, outgoing messages may be grouped
by delivery method and by a domain name within a delivery method.
For example, an administrator may specify a particular order in
which the messaging subsystem transfers or sends each of the
gateway alert messages to the respective communications gateway.
Alternatively, the messaging subsystem may transfer gateway alert
messages in a predefined order. Furthermore, the order in which
particular users receive alert messages may be prioritized by the
administrator. The order may be stored in a database. For example,
the messaging subsystem may transfer messages to users based on the
group or organization with which they are associated, or other user
specific information, as entered during registration. Furthermore,
a sender is provided the capability to select and transfer messages
to users individually. In an embodiment, gateway alert messages may
cause the network to disseminate alert messages to user terminals
via, for example, but not limited to, electronic mail per SMTP,
interactive World Wide Web pages per. HTML or XML, and short text
messages per SMS or IM. In at least one embodiment, the messaging
subsystem may cause the communication gateway to output one or more
HTML or XML popup screens that, when received by the user terminal,
appear at the top level (i.e., take over the screen) of the user
terminal display. An example of such a popup message service is the
"e/pop" service available from WiredRed Software of San Diego,
Calif., or CENS. Such popup messages may include visual and audio
effects.
[0163] In at least one embodiment, to send an alert message,
authorized users may send an authenticated and/or encrypted e-mail
directly to the messaging subsystem, log on to a secure capable web
page to fill out a web form of the alert message, and send an
authenticated wireless text message.
[0164] An alert originator may send an alert message to a group of
users by different methods. First, an alert originator may send an
alert message via web interface. Second, at alert message may be
sent via external trigger (e.g., incoming email, other incoming
data stream from a partner system).
[0165] A flowchart of a detailed messaging method 1800 is shown in
FIG. 18a. Referring to FIG. 18a, in at least one embodiment, a
messaging method may include a sender initiating a message, which
may be an alert, at 1805. To initiate a message; a sender may send
via web interface to the messaging subsystem 101 a request for an
interactive page. Upon receiving the request, the messaging
subsystem may render and transfer to the sender an interactive
page, which may be, for example, a World Wide Web page formatted in
accordance with HTML or XML. Upon receiving the interactive page,
the sender's terminal, which may be a user terminal 105, for
example, may output the interactive page to the sender to allow the
sender to select and enter and otherwise define various parameters
associated with the message by interacting with data
entry/selection fields on the interactive page provided by the
messaging subsystem 101 for this purpose. For example, the sender
may select properties of the message, including, but not limited
to, Alert Category (e.g., weather, traffic, . . . ), Recipient
groups (standard groups and/or individual users via custom group),
Excluded groups (groups of users who should not be receiving this
alert or message), Graphic profile (the receiving devices will take
advantage of suggested coloring scheme, font styles and other
formatting to the extent of their capabilities,(e.g., no formatting
for cell phones, full formatting for instant messaging clients),
Subject and Content of the alert or message (either one shared by
all categories of devices, such as cell phones, pagers, email
accounts, or each category of devices can have a different
content), Tag lines for each device class (e.g., `Sent by John
Smith to Group A, Group B . . . `), Attachments (files, predefined
responses, timestamps, etc--only the devices that can handle will
benefit, e.g., cell phones will get no file attachments, etc),
Priority of message (e.g., high/normal, which may affect
visualization of the alert depending on the delivery target), and
Forwarding of responses (e.g., have the system forward recipients'
responses to specified email address(es)). As explained herein,
these properties can also be prepopulated via a quick alert in
which a message can be sent as defined in quick alert or the quick
alert can be used as a template where blanks are filled prior to
sending. Furthermore, during the building of a message, a sender
may enter a different sending address prefix or different message
subject to reflect a different alert originator or originating
organization
[0166] After selecting and entering the message information, the
alert originator 102 (sender) may initiate transfer of the message
to the messaging subsystem 101 by selecting, for, example, a "send"
button on the interactive page using a computer mouse or keypad. At
this point, control may proceed to 1810 at which the web server 302
(which may be, in at least one embodiment, a PHP web page
processor) may store the collected information selected or entered
by the sender. In an embodiment, the collected information is
stored into the database 303. Further, the web server 302 may also
copy members of current custom group to individual alert recipients
and trigger the send alert function of the message engine 301.
[0167] As described earlier, alternatively the alert originator 102
may select, build, and send a message using a variety of
communication devices including, but not limited to, a web-enabled
mobile telephone terminal, SMTP formatted electronic mail, SMS,
Instant Message, Blackberry.TM. message, or any other such device
configured to generate similar non-voice messages, such as text
messages or telemetry data.
[0168] Furthermore, in an embodiment, the alert originator 102 may
send a message via external trigger mechanism such as, for example,
a remote sensor that includes a communication interface for
reporting event status. Such a device may have, for example, an SMS
message processor configured to transmit an SMS message to another
device upon the occurrence of a particular event such as, for
example, a utility meter remote reading device. Embodiments may
include other industrial control applications and devices that
generate messages as the alert originator 102. In such embodiments,
the web server 302 may receive an alert-triggering data stream, and
perform message processing functions in response thereto including
message decode, identify individual parameters of the alert, and
use of default values for those not included. Further, if the
external data stream refers to a quick alert, the web server 302
may populate a message using predefined parameters stored in the
database 303 associated with the particular quick alert. In
addition, the web server 302 may confirm authorizations of the
entity (sender or device) that delivered the data stream for
sending alerts with these properties. Finally, the web server 302
may submit the message or alert for delivery to the message engine
301
[0169] Control may then proceed to 1815, at which the message
engine 301 may perform group processing as follows. First, the
message engine may fetch the message or alert specification as
created by one of the above steps from the database 303. Next, the
message engine 301 may expand the list of explicitly listed
destination groups and excluded groups with all their
subgroups.
[0170] Control may then proceed to 1820, at which the message
engine 301 may build tag lines from the information provided
according to the specified tag line format for each carrier class.
Furthermore, the message engine 301 may bundle all alert-defining
data into a single data structure. At 1825, a method may include
determining if any destination groups are `remote groups.` If so,
control may proceed to 1830 at which the message engine 301 may
submit the alert definition into the corresponding remote
servers.
[0171] Following 1825 or 1830, control may proceed to 1835, at
which the message engine 301 may perform device specific processing
for message delivery to multiple user terminals or devices. In an
embodiment, the message engine 301 may perform device specific
processing for each user priority level separately. In at least one
embodiment priority level processing may proceed from highest
priority to lowest priority. Further details regarding device
specific processing at 1835 are shown and described herein with
respect to FIG. 18b.
[0172] Referring to FIG. 18b, in at least one embodiment device
specific processing 1835 may commence at 1860. Control may then
proceed to 1862, at which the message engine may find carriers that
have capcodes defined for at least one of the destination groups
identified to receive the message (i.e., capcoded carriers). A
capcode may be a unique address or identifier associated with a
particular device or user terminal
[0173] Control may then proceed to 1864, at which the message
engine may find all devices of delivery class this message or alert
is supposed to go to that belong to users with the currently
processed level of priority that belong to at least one of the
destination groups of this alert, and add to list of devices.
Control may then proceed to 1866, at which the message engine may
add all these devices into a destination device list. Control may
then proceed to 1868, at which the message engine may mark all
devices whose carrier is `capcoded` for removal later; Control may
then proceed to 1870, at which the message engine may look up
dynamic properties of the destination groups and add all users that
match these search criteria into the individual user recipients
list. Control may then proceed to 1872, at which for each
individual user recipient of the currently processed user priority,
the message engine may look up all their devices that match the
carrier class used for his alert, and add resulting devices to the
list of devices, Control may then proceed to 1874, at which the
message engine may find devices of all users (of current priority)
that belong to at least one excluded group, and remove such devices
from the list of devices. Control may then proceed to 1876, at
which the message engine may remove all devices that were marked
for removal earlier (due to capcodes). If this is the highest
priority loop, then control may proceed to 1878, at which the
message engine may add capcodes for all involved groups into the
list of devices. Control may then proceed to 1880, at which device
specific processing 1835 may end.
[0174] Returning to FIG. 18a, wherein following device specific
processing at 1835, if this is a local message such as a local
alert (i.e., not a remote alert), the message engine may store all
the collected information in the database 303 for alert tracking
and reporting purposes. Control may then proceed to 1840, at which
the message engine may execute message delivery. In at least one
embodiment, for each different delivery module (i.e., delivery via
email, instant messaging, voice call, etc.), the message engine may
load the code responsible for delivering through this method and
launch the code with the message or alert information and the list
of devices to be handled by this module. Control may then proceed
to 1850, at which a method may include repeating 1835 through 1850
for the next user priority level. In at least one embodiment, the
messaging subsystem 101 may include one or more message delivery
modules for delivering messages via particular communications
interface and medium' such as, for example, electronic mail
(email), paging, cell phone, SMS, and the like.
[0175] Further details regarding module specific delivery 1845 are
shown and discussed with respect to FIG. 18c. Referring to FIG.
18c, in at least one embodiment, the message engine may 301 may
include a mail processor 304 that may be configured to support
email delivery (e.g., an email delivery module) commencing at 1882.
Control may then proceed to 1883, at which the mail processor may
accept a list of devices to deliver messages to. In an embodiment,
the dispatcher may only provide those that apply to this module,
not for all possible devices). For each Delivery Method handled by
this module (for example, delivery methods "AT&T" and
"Cingular" under module `SMS delivery`), the mail processor may
perform 1884 through 1894.
[0176] Following 1883, control may proceed to 1884, at which the
mail processor may drop file attachments if this is a limited
message length delivery method. Control may then proceed to 1886,
at which the mail processor may calculate how many pieces this
alert needs to go out in for this delivery method (for example,
using the maximum number of characters per message info associated
with this delivery method). Control may then proceed to 1888, at
which for each email piece the mail processor may generate the
message content of that piece and store it in, for example, local
non-volatile memory such as a hard disk. Control may then proceed
to 1890, at which the mail processor may calculate how many
individual emails will be sent using the information about the
number of pieces necessary and number of devices targeted and
considering also how many devices can be bundled together in a
single email. Further, at 1890, the mail processor may calculate,
given the number of available parallel delivery processes
(buckets), how many emails to put to each bucket to distribute the
load evenly across them. Control may then proceed to 1892, at which
the mail processor may generate headers for each outgoing email
(put the same number of emails into each bucket) using the list of
devices, bundle devices with the same email domain (destination
server) together to minimize the number of outgoing connections,
link the body of the email generated above with this header (note
that each body is shared by many headers thus making this process
more efficient) and, after both header and body of the message is
created, providing the email ready to be fetched by the delivery
daemon. For each bucket, there may be several delivery daemons that
are monitoring the bucket looking for any new messages submitted
there for delivery. When these daemons find any such message, they
identify the recipients and initiate SMTP connections with the
destination servers. Control may then proceed to 1894, at which a
method may include repeating 1884 through 1894 until messages for
all devices have been delivered.
[0177] Furthermore, at least one embodiment may include a response
handling method for tracking responses to delivered messages
following message transfer and delivery as shown and described with
respect to FIGS. 18a-c above. In particular, FIG. 19 is a flow
chart of a method 1900 of response tracking in accordance with at
least one embodiment. Referring to FIG. 19, a response handling
method 1900 may commence at 1905. Control may then proceed to 1910,
at which the message engine may receive one or more responses from
user terminals via communication channels (e.g., via email, via
other channels). For each received response, the message engine may
process the response as follows. Control may then proceed to 1915,
at which the message engine may identify the device or user
terminal that the response came from (sender's email address,
instant message client identifier, other ID). Control may then
proceed to 1920, at which the message engine may identify which
message or alert this is a response for (i.e., correlate response
with message/alert). Control may then proceed to 1925, at which the
message engine may look for this identifier in a device table. If
found, the message engine may determine that this message is a
valid response from a device that received the alert. If not found,
the message engine may determine that the response came back from
an unknown sender. This may occur, for example, due to the message
or alert having been sent to an invalid destination and this is a
bounced message (e.g., sent by a remote server telling the
messaging subsystem the destination (email account, cell phone,
etc.) doesn't exist). In both cases, control may then proceed to
1930 at which the message engine may store the response in a
response log for the given message or alert but mark the response
as either identified or other. Control may then proceed to 1935 if
the response is identified, at which the message engine may mark
the owner of the device as. a person who responded to the
message/alert and adjust the message/alert statistics accordingly.
Control may then proceed to 1940, at which if the sender of this
alert requested responses to be forwarded, the message processor
may forward the response to specified destinations at 1945. Control
may then proceed to 1950, at which a method may end. Furthermore,
in at least one embodiment, an auto-scrubber capability may be
provided to automatically remove bounced addresses from reply
tracking.
[0178] In at least one embodiment, the messaging subsystem may
include several predefined quick alert messages. Examples of user
selectable icons for exemplary quick alerts is shown in FIG. 10.
Referring to FIG. 10, quick alerts may include Bio Attack, Dirty
Bomb, Earthquake, and Mass Casualty Incident, as a minimum. In an
embodiment; an administrative user may initiate a quick alert by
selecting an icon corresponding to the desired quick alert message
by, for example, clicking on the icon with a computer mouse. Upon
administrative user selection of a quick alert message, the
messaging subsystem 101 may retrieve predefined alert message text
from a database, assemble one or more gateway alert messages as
specified in the database, and transfer the gateway alert
message(s) to a predefined set of communication gateways, with no
further user involvement. In an embodiment, in order to send a
quick alert, no PIN code may be required.
[0179] In at least one embodiment, users may interact with the
messaging subsystem 101 via the web server 302. To access the web
server 302, in an embodiment, a user may enter the URL associated
with a web server 302 of the messaging subsystem 101 into the
address line of a World Wide Web browser application.
Alternatively, a user may select an associated hyperlink contained
on an interactive page using a pointing device such as a mouse or
via keyboard commands. This causes an HTTP-formatted electronic
message to be transmitted to the web server 302 (after Internet
domain name translation to the proper IP address by an Internet
proxy server) requesting a HTML or XML page. In response, the web
server 302 generates and transmits a corresponding interactive
HTTP-formatted HTML or XML page to the requesting terminal, and
establishes a session. The HTML or XML page may include data entry
fields in which a user may enter information such as the client's
identification information, contact information, etc. The user may
enter the prompted information into the appropriate data entry
fields of the HTML or XML page and cause the terminal to transmit
the entered information via interactive HTML or XML page to the web
server 302. In response to receiving the user transmitted page
populated with user provided information, the web server 302 may
validate the received information by comparing the information
received to corresponding stored data. This validation may be
requested by the web server 302 to be performed by a database
server by executing one or more validation scripts. If the database
server 302 determines that the information is valid, or in response
to an entry request, then the web server 302 may generate and
transmit a report page to a terminal. In this way, page content for
pages provided by the web server 302 may be dynamic, while page
frames may be statically defined. The dynamic and static
information may be included in a database
[0180] Thus, the systems and methods of the embodiments described
herein may provide to emergency management agencies, first
responders, government, near government and educational
organizations and businesses the ability to communicate to large
groups of individuals quickly and reliably when other means of
communication such as, for example, land voice lines, cell voice
communication, corporate e-mail are down or otherwise not
available. In particular, such embodiments may provide the
capability for individuals and groups to be notified of emergency
situations through the delivery of text messages. Such messages may
also describe the nature of the emergency, recommend next steps,
and provide situation updates. Furthermore, the systems and methods
may also be used for non-emergency daily communication to reach
large numbers of users. In addition, the systems and methods may
include multiple interconnected messaging subsystems in a message
processing network in which authorized senders of one messaging
subsystem at a first messaging center can send alerts and
notifications to users other messaging subsystems at other
messaging centers.
