`
`FIELD
`
`The present disclosure relates to message broadcast sys-
`tems and in particular location-specific mes sage broadcasting
`aggregator and gateways.
`
`BACKGROUND
`
`With the events of 9/ 1 1, there has been increased concern
`with the ability of present systems for providing public ser-
`vice broadcasting of messages ar1d 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 notifica-
`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 tlie subscription-based Short Message Ser-
`vice (SMS) messaging capability for mass messaging using
`mobile telephones and compatible devices. However, SMS
`systems and technology have significant technical limitations
`and experience with such systems has been disappointing due
`to significant delays ir1 tl1e 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 a11d 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, tl1e use of SMS technology for broadcasting
`requires enormous network infra structure utilization. A tele-
`communication system can suffer from congestion, not only
`in its voice traflic charmels. but also in its narrow—band data
`chamiels as are used for the SMS service. To send an SMS
`message, network cor11pone11ts 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
`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 pho11e
`users attempt to initiate a voice call at tl1e sar11e time. Tele-
`
`2
`communication networks are not designed or deployed to
`handle such high levels of simultaneous call attempts.
`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 mes sage individually and attempts to deliver
`the SMS message through an interrogation of the Home
`Location Register (HLR) of the telecon1111unication service.
`An HLR is a data base which registers or keeps track of the
`presence of a mobile unit user within the HLR’s defined
`serving network. The HLR queries the database and deter-
`mines whether tl1e 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 iii the
`telecoimutmication 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 tlie location area where tl1e
`intended user’ s mobile unit was last known to be operating. 1f
`the intended recipient is located in the particular cell area, the
`mobile unit is paged. As such, potentially thousands 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 perfonn SMS call set up with tl1e mobile unit. Next,
`a cipher key is sent by the Home Location Register (11LR)/
`Authentication Center (AUC) to the mobile unit, assuming
`that the mobile unit had previously activated the ciphering of
`the charmel. Once the cipher key is successfully received and
`acknowledged, the SMS mes sage is sent over the control
`channel to the mobile unit. The SMS message transmission
`utilizes about 5 seconds of control charmel time per SMS
`message.
`Ifl however, tl1e intended recipient is not located ir1 tl1e
`, home serving area ofthe HLR, then signaling message is sent
`to the serving mobile network’s Visitor Location Register
`(VLR). 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 ines-
`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 eacl1
`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-
`specific messaging.
`Additionally, SMS messaging requires considerable call
`processing load on the teleconununication 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 tl1e same time. The potential initiation ofbroad-
`
`15/28

`
`3
`cast SMS volumes will not only affect network resources for
`SMS messaging, but also negatively affect ability of the tele-
`communication networks to set up and support voice traflic
`during any period ofmessage 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
`configuration 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. Tl1e 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 traflic
`which is not normally handled by the traflic channels on the
`other timeslots.
`Howcvcr,
`in this prior art systcm, SMS and Wireless
`Access Protocol (WAP) messaging utilize capacity on these
`chamiels 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/or paging calls.
`As such, during heavy messaging, the related high volumes of
`messaging traflic 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
`chamiel allocation utilizes an additional trafiic channel which
`is converted into another 8 control charmels for the duration of
`the peak SMS or paging loads. However, this results in the
`loss of the traffic channel for voice communications.
`Furthcr stratcgics have included the immediate assignment
`to a traffic chaimel. In this system, when a voice call is
`attempted, the voice call is sent to a trallic chaimel directly
`where signaling will be performed on the traffic channel.
`This, however, occupies the traffic channel for a longer time
`than would otherwise be the case. There is a limit on the
`number oftraffic channels that can utilize this feature. In most
`cases, only one traffic charmel is converted thereby only lirn-
`ited the solution to 8 new SDCCII channels. The impact of
`call failure due to control charmcl depends on the traflic
`capacity of the cell. In high density cells, when a large quan-
`tity of SMS messaging traffic is offered, congestion occurs
`due to the each cell having over one hundred traflic channels
`within the cell.
`the telecommunication service provider
`In operation,
`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-
`tivcly impacts the opportunity for using SMS messaging for
`broadcasting emergency mes sages to users ofthose networks.
`Throttling often significantly delays the delivery of the SMS
`message, even though it’s timing delivery in an emergency is
`critical. Furthermore, ifa 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 dcfincd 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 11ot hi the intended area.

`In the altemative, 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
`(PLB S) 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 Vvleb
`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 mes sage is sent over the loca-
`tion broadcast channel. A mobile unit or Broadcast Agent
`phone that is configured to receive location broadcast mes-
`sages, which is in the idle mode and which is located in the
`predefined cell receives the broadcast message and displays
`the message on its screen.
`location broadcasting is transmitted from the predefined
`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., IILR, VLR,
`ctc.
`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
`identification ofthe 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 official government-to-citizen information
`broadcast to all compatible telecommunication receiving
`devices in, or entering, an predefined at-risk geographic loca-
`tion or area.
`The PLBS system sends any public service or emergency
`information associated with any event, determined by autho-
`
`6
`rized messaging entities that may affect public safety. These
`include utility outages, missing child alerts, severe weather
`warnings, flood wamings, 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 predetennined fixed 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.
`such as
`Local
`telecommunications
`service providers
`~ mobile or cellular telephone service providers provide the
`local infrastructure and deployed technologies to enable the
`service message location broadcast
