`
`BACKGROUND
`

`
`2
`When an SMS message is transmitted, the SMS message is
`signaled to an SMS center of the telecommunication service
`provider. The SMS center acknowledges each and every
`requested SMS message individually and attempts to deliver
`the SMS message through an interrogation of the Home
`Location Register (HLR) of the telecommunication service.
`An HLR is a data base Which registers or keeps track of the
`presence of a mobile unit user Within the HLR’s de?ned
`serving netWork. The HLR queries the database and deter
`mines Whether the intended SMS message recipient is cur
`rently attached to the netWork and if so, to Which netWork
`sWitch the user is attached. The HLR is queried using the
`telecommunication signaling netWork.
`If an intended user is located or attached to a sWitch in the
`telecommunication service provider’s netWork, the particular
`netWork sWitch is signaled over the telecommunications sig
`naling netWork to set up the SMS message call. That serving
`netWork sWitch of the mobile carrier initiates a query or
`message attempt to every cell in the location area Where the
`intended user’s mobile unit Was last knoWn to be operating. If
`the intended recipient is located in the particular cell area, the
`mobile unit is paged. As such, potentially thousand of cells
`are queried in order to determine the presence of an intended
`mobile unit. Each queried cell requires paging and calling
`capacity resources for each mobile unit Which is attempted to
`be paged. In some cases, if the mobile unit does not reply, the
`Whole Mobile Service Carrier (MSC) area is paged Which in
`many instances requires the paging of several thousands of
`cells.
`When the mobile unit replies by sending an access burst to
`the cell transceiver currently serving the mobile unit, the cell
`site allocates a stand-alone dedicated control channel (SD
`CCH) to perform SMS call set up With the mobile unit. Next,
`a cipher key is sent by the Home Location Register (HLR)/
`Authentication Center (AUC) to the mobile unit, assuming
`that the mobile unit had previously activated the ciphering of
`the channel. Once the cipher key is successfully received and
`acknoWledged, the SMS message is sent over the control
`channel to the mobile unit. The SMS message transmission
`utiliZes about 5 seconds of control channel time per SMS
`message.
`If, hoWever, the intended recipient is not located in the
`home serving area of the HLR, then signaling message is sent
`to the serving mobile networks Visitor Location Register
`(V LR). The VLR registers and tracks mobile unit users Who
`are outside of their home location. In that case, the VLR is
`queried via the signaling netWork to verify that the user is
`currently attached to the remote sWitch.
`Each SMS message is a narroW-cast message in that each
`message is generated and transmitted via the SMS Center to
`a particular telecommunication user or unit. The SMS mes
`sage is delivered, as discussed above, to the intended recipient
`by capable netWorks Wherever the intended recipient is
`located, independent of geographic area or location.
`As such, SMS messaging for emergency-based messaging
`requires that SMS messages be created and sent to each
`mobile unit even though the particular user phone is not
`located in the particular geographic area in Which the emer
`gency is located. SMS service is not capable of position
`speci?c messaging.
`Additionally, SMS messaging requires considerable call
`processing load on the telecommunication system and infra
`structure considering that the above process is multiplied by
`the demand of thousands or tens of thousands of SMS call set
`up requests at the same time. The potential initiation of broad
`cast SMS volumes Will not only affect netWork resources for
`SMS messaging, but also negatively affect ability of the tele

`
`With the events of 9/11, there has been increased concern
`With the ability of present systems for providing public ser
`vice broadcasting of messages and Warnings to the public.
`Existing public service Warning systems are antiquated and
`provide only limited access to the public Who may be in need
`of knoWing of potential emergencies or danger. Additionally,
`existing systems do not provide for location-based noti?ca
`tion or broadcasting.
`As such, there is a need for an improved method and system
`for providing timely information to the public related to
`potential hazards affecting them. One suggested solution is
`the utiliZation of the subscription-based Short Message Ser
`vice (SMS) messaging capability for mass messaging using
`mobile telephones and compatible devices. HoWever, SMS
`systems and technology have signi?cant technical limitations
`and experience With such systems has been disappointing due
`to signi?cant delays in the delivery of SMS messages and
`negative impacts to the netWorks due to congestion.
`Short Message Service (SMS) is only offered or available
`on a limited basis. This is due to the limited technical and
`netWork support for the service and is also due to the service
`being offered by Mobile Service Providers and Wireless net
`Work providers on a subscription basis. As such, use of the
`SMS service capability for emergency broadcasting is very
`limited.
`Additionally, the use of SMS technology for broadcasting
`requires enormous netWork infrastructure utiliZation. A tele
`communication system can suffer from congestion, not only
`in its voice tra?ic channels, but also in its narroW-band data
`channels as are used for the SMS service. To send an SMS
`message, netWork components are utiliZed to provide an SMS
`message call set up for each individual SMS message recipi
`ent. In order to send a single SMS message, all SMS message
`call processing procedures have to be repeated for each and
`every message, one by one, for all intended recipients. A
`60
`single SMS message requires signaling and processor capac
`ity and utiliZation similar to that required to establish a voice
`call. As such, the impact on netWork resources for broadcast
`ing SMS messages is the same as having thousands of phone
`users attempt to initiate a voice call at the same time. Tele
`communication netWorks are not designed or deployed to
`handle such high levels of simultaneous call attempts.

`communication networks to set up and support voice tra?ic
`during any period of message broadcasting as these resources
`are shared by both services.
`As a further example of the limitation of existing solutions
`to message broadcasting, the Well deployed Global Standard
`for Mobile Communications (GSM) system typically deploys
`in a single GSM cell several transceivers. A typical GSM cell
`con?guration includes betWeen 6 and 12 transceivers. Each
`such transceiver includes 8-timeslots. Each timeslot supports
`a single phone call.
`In such an arrangement, one of the transceivers is selected
`to be the SMS carrier. The SMS carrier transceiver is arranged
`differently, having one timeslot dedicated to broadcast SMS
`messages and paging and another one Which is utiliZed to
`from 8 control channels Which are referred to as Stand-Alone
`Dedicated Control Channels (SDCCH). The SDCCH carry
`out control and call set-up functions and carry the SMS tra?ic
`Which is not normally handled by the tra?ic channels on the
`other timeslots.
`HoWever, in this prior art system, SMS and Wireless
`Access Protocol (WAP) messaging utiliZe capacity on these
`channels making them unavailable for other purposes such as
`voice call set up. Additionally, each of the SDCCH channels
`can only handle a limited number of SMS and/orpaging calls.
`As such, during heavy messaging, the related high volumes of
`messaging tra?ic may have a negative affect on other services
`including the set up of voice calls.
`To compensate for these and other SMS messaging limita
`tions, dynamic channel allocation Was developed. Dynamic
`channel allocation utiliZes an additional tra?ic channel Which
`is converted into another 8 control channels for the duration of
`the peak SMS or paging loads. However, this results in the
`loss of the tra?ic channel for voice communications.
`Further strategies have included the immediate assignment
`to a tra?ic channel. In this system, When a voice call is
`attempted, the voice call is sent to a tra?ic channel directly
`Where signaling Will be performed on the traf?c channel.
`This, hoWever, occupies the tra?ic channel for a longer time
`than Would otherWise be the case. There is a limit on the
`number of traf?c channels that can utiliZe this feature. In most
`cases, only one tra?ic channel is converted thereby only lim
`ited the solution to 8 neW SDCCH channels. The impact of
`call failure due to control channel depends on the tra?ic
`capacity of the cell. In high density cells, When a large quan
`tity of SMS messaging tra?ic is offered, congestion occurs
`due to the each cell having over one hundred tra?ic channels
`Within the cell.
`In operation, the telecommunication service provider
`addresses this limitation by throttling the SMS messaging
`rate so that it is manageable and does not create congestion
`problems. HoWever, such message load management nega
`tively impacts the opportunity for using SMS messaging for
`broadcasting emergency messages to users of those netWorks.
`Throttling often signi?cantly delays the delivery of the SMS
`message, even though it’ s timing delivery in an emergency is
`critical. Furthermore, if a message fails to be delivered, the
`SMS center repeatedly attempts to deliver the message,
`thereby causing further congestion and message backlog.
`Additionally, as discussed SMS messaging is not location
`based and does not send messages to intended recipients
`located Within a de?ned geographic location. Since many
`telecommunication users Will be messages independent of
`their location, many of the generated SMS messages are sent
`to users Who are not in the intended area.
`In the alternative, some next-generation phone systems
`include a basic cell-based broadcasting capability, e.g., GMS,
`CDMA and UMTS. In such systems, the cell broadcasting

`capability allocates a portion of each timeslot bandWidth
`capacity in each cell as a reserved broadcast timeslot. While
`the cell broadcast capability in included in many neW equip
`ment being deployed, cell broadcasting systems and services
`have not been developed Which effectively utiliZe the tech
`nology.

`
`DETAILED DESCRIPTION
`
`The folloWing description is merely exemplary in nature
`and is in no Way intended to limit the disclosure, its applica
`tion, or uses.
`The public service message location broadcasting system
`(PLBS) according to one or more embodiments provide for an
`improved system and method for public service broadcast
`messaging. A public service message location broadcasting
`system (PLBS) operator provides a Broadcast Agent Web
`Portal or Webpage or other similar GUI interface, implemen
`tation and maintenance of the networks’ cell-broadcast mes
`saging components, netWorks and platforms, administration
`and operation of the public service message location broad
`casting system, and interfaces to local telecommunication
`service providers including mobile unit service providers.
`According to one embodiment in the event of a serious
`public emergency, a short text message is sent over the loca
`tion broadcast channel. A mobile unit or Broadcast Agent
`phone that is con?gured to receive location broadcast mes
`sages, Which is in the idle mode and Which is located in the
`prede?ned cell receives the broadcast message and displays
`the message on its screen.
`Location broadcasting is transmitted from the prede?ned
`cell in a doWnlink only mode and therefore does not require
`functionality or netWork resources from the mobile services
`provider or from their any portion of the mobile service
`provider’s mobility management resources, e.g., HLR, VLR,
`etc.
`Public service message location broadcasting system pro
`vides for the simultaneous sending of public service mes
`sages to millions of subscribers With less impact on the sup
`porting netWorks than a single SMS-message. As such,
`minimal to no netWork congestion Will result.
`A public service message location broadcasting system
`(PLBS) receives emergency or public service messaging and
`identi?cation of the target broadcast area from public service
`or government entities. The PLBS provides location broad
`cast message enablement, security and multi-carrier interop
`erability and connectivity to the telecommunication service
`providers offering services Within the target broadcast area.

`A public service message location broadcasting system
`and method according to one or more embodiments provides
`for the development, transmission, delivery and display of a
`message that is an of?cial govemment-to-citiZen information
`broadcast to all compatible telecommunication receiving
`devices in, or entering, an prede?ned at-risk geographic loca
`tion or area.
`The PLBS system sends any public service or emergency
`information associated With any event, determined by autho
`riZed messaging entities that may affect public safety. These
`include utility outages, missing child alerts, severe Weather
`Warnings, ?ood Warnings, and terrorist threat Warnings. The
`messages are broadcast by public service message location
`broadcasting systems participating With local telecommuni
`cation netWorks.
`Unlike other emergency messaging services that require
`the recipient’s identity, a predetermined ?xed delivery loca
`tion, and usually the payment of a service fee, public service
`message location broadcasting system uses broadcast mes
`saging technology to reach an unlimited number of people in
`real time, With no pre-event subscriber action required.
`Public service message location broadcasting system uses
`cell-broadcast SMS (C-BSMS) technology to provide a mes
`sage or alert to a single cell geographic location, a neighbor
`hood, a city, or an entire nation With minimal impact to the
`hosting telecommunication netWorks.
`Local telecommunications service providers such as
`mobile or cellular telephone service providers provide the
`local infrastructure and deployed technologies to enable the
`service message location broadcasting system to transmit
`public messages in a timely manner to the public that may be
`at risk using a standard and commonplace mobile telephone
`unit.
`The public service message location broadcast system and
`methods described herein provide the functions and steps
`necessary to ensure that the Broadcast Agents are authoriZed
`to send the requested broadcast messages to the de?ned
`broadcast target area. The PLBS con?guration described
`herein provide for internal controls for insuring that the net
`Work and components are secure and that messages are autho
`riZed prior to transmittal. The public service message location
`broadcast system provides the interface to the Broadcast
`Agents to ensure simple and timely de?nition of the broadcast
`target area, the message and the authenti
