`ABSTRACT
`
`Informing a number of users about an emergency or other
`situation of public interest is accomplished using a broadcast
`service. A specific identifier is used in a paging message for
`activating broadcast service in terminals. A terminal checks a
`received paging message with regard to the presence of the
`specific identifier and when detecting the specific identifier,
`switchesto a broadcast modefor receiving broadcast content.
`The received broadcast emergency contentis notified and/or
`displayed to the users of the terminals.

`
`This application U.S. NationalState ofInternational Appli-
`cation No. PCT/EP2008/053915, filed Apr. 2, 2008 and
`claims the benefit thereof. The International Application
`claims the benefits of European Application No. 07006867
`filed on Apr. 2, 2007, both applications are incorporated by
`reference herein in their entirety.
`
`BACKGROUND
`
`The field of communication in particular mobile commu-
`nication, and more particular to information provision by
`using paging andcell broadcast services is addressed herein.
`Morespecifically, the enablement of emergency information
`provision by using enhanced TMS]definition and cell broad-
`cast services is addressed.
`
`Currently informing a large public about possible emer-
`gencies and hazards mainly is accomplished acoustically
`using such as a siren which can give only very limited infor-
`mation and requires a second information channel, e.g. radio
`broadcast, to get helpful guidance. Even in some regions of
`the world, such infrastructure does notexist, or the low popu-
`lation density makes deploymentthereofinefficient.
`GSMasoftoday has no specific precaution to support an
`efficient emergency information distribution.
`Described below are methods and devices for conveying
`information such as emergency informationto a large number
`of people in an efficient way.
`In at least one of the implementations described below,
`public land mobile network, PLMN, based technology is
`used. Existing infrastructures can be utilized. In one or more
`of the embodiments, GSM is a choice of system due to its
`almost global coverage with more than one billion users
`world wide.
`
`SUMMARY
`
`According to at least one or more of the embodiments, an
`existing broadcast service can be used such as the GSM
`Cell-Broadcast Service which is an SMStype broadcast ser-
`vice and delivers in one session the notification and the mes-
`
`sage content. The cell-broadcast service allows sending of
`short messages to all mobile terminals attached or registered
`to a base station or cell. GSM 03.41 defines this Short Mes-
`
`sage Service-Cell Broadcast (SMS-CB) which allows mes-
`sages to be broadcast to all mobile users in a specified geo-
`graphicalarea.
`The technology and standard is ready but not frequently
`used because the system design normally requires a very
`frequent reading of a notification channel, omitting almost a
`power saving sleep mode e.g. in a discontinuous reception,
`DRX, mode.This has harsh consequenceson the battery drain
`and the stand-by time of a terminal. Therefore operators do
`not use these services but most ofthe terminals are supporting
`the feature.
`In accordance with at least one of the embodiments, a
`broadcast service such as the Cell-Broadcast service is used
`for emergency support, yet avoiding the above mentioned
`significant consequences on the stand-by time of the mobile

`terminals. In at least one of the embodiments, this service is
`actively invoked by the terminalin case of need only, using a
`paging mechanism.
`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`These and other aspects and advantages will become more
`apparent and more readily appreciated from the following
`description ofthe exemplary embodiments, taken in conjunc-
`tion with the accompanying drawings of which:
`FIG. 1 is a timing diagram showing an embodiment,
`FIG. 2 is a flow chart of a method in accordance with an
`embodiment,
`FIG. 3 is a basic block diagram illustrating an aspect of
`paging and broadcast in accordance with one, more orall of
`the embodiments,
`FIG.4 is a block diagram of an embodimentof a terminal,
`and
`FIG. 5 is a flow chart of an embodiment of a method as
`
`implementedin a terminal.
`
`DETAILED DESCRIPTION OF THE PREFERRED
`EMBODIMENT
`
`Reference will now be made in detail to the preferred
`embodiments, examples of which are illustrated in the
`accompanying drawings, wherein like reference numerals
`refer to like elements throughout.
`FIG. 1 shows an embodimentin which a terminal 1 such as
`a mobile terminal, mobile station or user equipmentetc. is
`attached to a network via a base station system, BSS, or
`mobile switching center, MSC,2 or any other access network.
`The network may include an emergency center 3 for handling
`emergency matters, or any other device which will instruct
`the network to broadcast emergency contentor other content
`of public interest e.g. in case of emergencies. Whenthe net-
`work learns, e.g. from the police or a medical institution,
`about an emergency or any other type of situation such as
`traffic jam etc. on which all users attached to a cell of the
`network should be informed, the network starts, in step S11,
`a broadcast service such as a cell-broadcast service. In step
`$12, the radio access network, RAN, or BSS/MSC2 beginsto
`broadcast emergency content specifying the actual emer-
`gencyorother situation of public interest.
`Further, in step $13, the RAN or BSS/MSC2 sends one or
`more paging messages which include a specific identifier
`such as an E-TMSI which is accepted by all terminals 1
`receiving the paging message. The steps S12 and S13 can also
`be carried outin reversed order or simultaneously. In response
`to the receiptof the paging message on step S13, the terminal
`1 switches, in step S14, to Cell-Broadcast Service support and
`thusstarts to listen to the broadcast channel. In step $15, the
`terminal 1 displays or notifies the content received from the
`broadcast channelto the user ofthe terminal 1 via a display or
`acoustical output the terminal 1.
`Instead of the Cell-Broadcast Service, another broadcast
`service can also be used for informing the terminals on the
`emergencyor other content.
`FIG.2 illustrates an embodimentof a method.In step $21,
`the network is informed about an emergency situation or
`other situation of public interest by receiving emergency or
`other actual contents enriched by a severity. The network
`starts or uses cell broadcast service distributing emergency or
`other actual content in step S22. Further, in step S23, the
`network starts sending paging messages which include a spe-
`cific identifier for indicating an emergencyor othersituation.
`The steps S22 and S23 can also be carried outin reverse order,

`or simultaneously. The sent paging messages may indicate an
`emergencysituation by help of the specific identifier such as
`an E-TMSI. When the terminals receive, in step S24, the
`paging message including the specific identifier such as
`E-TMSI, the terminals switch to support or activate thecell
`broadcast service or mode.In step S25, the terminal displays
`or announcesor otherwise notifies the user of the terminal on
`the broadcast content.
`FIG. 3 showsa general overview wherein a network suchas
`a 3GPP network 31 sends paging messages and broadcast
`messagesto all terminals 1 attached to a cell of the cellular
`mobile network 31. The paging messages and broadcast mes-
`sages mayalso be transmitted in one, more orall other cells of
`the network 31 for increasing the numberofusers receiving
`the broadcast content.

`accordance with one or more embodiments. The terminal 1 of

`that the paging messageis to be interpreted as an emergency
`notification. The terminal is configured to switchto, or acti-
`vate the broadcast service whenreceiving such a paging mes-
`sage including the specific identifier. The paging mechanism
`is thus modified to switch the terminalto the broadcast recep-
`tion mode. The mechanism and messages are backwards
`compatible with terminals not being able to interpret paging
`messages as emergency notifications. A terminal which is
`unable to interpret a paging message including the specific
`identifier as an emergencynotification may simply disregard
`the paging message.
`In at least one of the embodiments, such a paging message
`is formed so as to include the specific identifier formed as a
`specific TMSI. All terminals are identifying the received spe-
`cific TMS]as valid.
`Usually terminals receive a TMS] derived from the inter-
`national mobile subscriber identity, IMSI. The use of the
`IMSIallowsa staggering of the terminals to be paged into 10

`broadcast mode unit 43 supporting a cell-broadcast service by
`from the IMSI)ofall terminals in a cell sending the paging

`messagelisten to a paging message. The network will change
`cast messages. A memory unit 44 serves for storing a TMSI
`the paging groups in the next paging cycles so as to page all
`allocated to the terminal 1 from the network 31 and/or one or
`terminals.
`
`more specific identifiers which, when transmitted from the
`network, will cause the terminal 1 to start or activate the
`support ofthe cell-broadcast mode. A control unit 45 controls
`someorall functions of the terminal1 orat least some of the
`units shown in FIG. 4. An acoustical unit 46 enables acous-
`tical announcement of broadcast content if available in, or
`convertible to, acoustical form. A display unit 47 enables
`visual display of broadcast or other content.
`FIG.5 illustrates functions of a terminal such as terminal 1
`in accordance with one, more or all of the embodiments.
`Whenthe terminal 1 receives, in step $51, a paging message,
`the terminal 1 or paging mode unit 42 of FIG.4 checks, in step
`$52, whether the TMS]included in the paging message cor-
`responds to the TMS] allocated to the terminal 1 from the
`network, or to the specific identifier, or one of the specific
`identifiers, indicating an emergencyorothersituation of pub-
`lic interest, and stored in memory unit 44 of FIG. 4. When the
`terminal detects, in step S52 that the TMSI in the paging
`message correspondsto the temporary TMS]allocated from
`the networkto the terminal, the process proceeds to step S53
`wherein the terminal establishes a physical and/or logical
`channel in the customary manner.If the terminal detects, in
`step $52 that the TMS]in the paging message correspondsto
`the specific identifier E-TMSI, or one of the specific identi-
`fiers stored in memory unit 44, the process proceedsto step
`S54 wherein the terminal 1 switches to support orlisten to the
`Cell Broadcast mode, and receives, notifies and/or displays
`the broadcast content, e.g. emergency content, in step S 55.
`When the TMSIof the received paging message does not
`correspond to either of the allocated TMSI or E-TMSI, the
`paging message is neglected without any response.
`In accordance with at least one or more of the embodi-
`
`ments, a paging mechanism such as the existing circuit-
`switched, CS, paging mechanism may be used for sending a
`paging message to the terminals whichare attached to acell or
`listening to a sender such as a base station or Node B. The
`paging message may include a specific identifier such as a
`specific temporary mobile subscriber identity, TMSI. The
`terminal checks a received paging message in the usual man-
`ner with regard to the TMSI or identifier so as to detect
`whether the paging messageis directed to the terminal. When
`the terminal detects that the identifier included in the paging
`message1s the specific identifier the terminalis thus informed

`
`3GPP TS 23.003 V7.1.0 (2006 September), chapter 2
`defines actually valid subscriber identities such as IMSI,
`TMSIor P-TMSI. In accordance with one, moreorall of the
`embodiments, an additional specific identifier such as EGmer-
`gency)-TMSIcan be used, and mayadditionally be defined in
`this chapter. Instead of E(mergency)-TMSI any other name
`may be used for this specific identifier, provided that the
`format and contentis suchthat the terminals can recognize the
`specific identifier as an indication to switch to the listening to
`the cell broadcast service.
`Similar to a normal TMS]assigned to a terminal having
`local significance within a VLR andthe area controlled by a
`VLR,or within an SGSN and the area controlled by an SGSN,
`the specific identifier such as E-TMSI mayconsistof 4 octets
`and can be coded using, e.g., a full hexadecimal representa-
`tion, with the structure and coding optionally chosen in order
`to meet local needs. The terminals may be informed on the
`specific identifier or identifiers either at the production stage
`or later by device managementor the like, and store this
`specific identifier or identifiers either continuously or until
`replacement by other specific identifiers or cancellation.
`The discrimination between a normal TMSI temporarily
`assigned to the terminal and the specific identifier may be
`done using somebits of the TMSI. An E-TMSIcan befixed
`and will thus not only temporarily be assigned, and can be
`valid in several terminals and cells so that the specific iden-

`The specific identifier such as E-TMSI maybe stored,
`similar to anormal TMSI, in the subscriber identity module,
`SIM,or in anotherstorage of the terminals so that someorall
`terminals store the samespecific identifier.
`Whenreceiving a paging message, the terminals check if
`the TMSIincluded in the paging message correspondsto the
`allocated TMSIorto the specific identifier.
`Contrary to a normal TMSI, the specific identifier is not
`exclusively allocated to one terminal only but is identically
`set in several terminals or all terminals in accordance with
`one, more orall of the embodiments.
`A terminal may be a mobile station or user equipment or
`any other type of mobile or stationary device.
`Terminals such as mobiles in accordance with at least one

`TMSI, which may also indicate a paging group allocation,
`and is generically acceptedbyall terminals. The E-TMSI uses
`a numberpattern unique to indicate emergencysituations. In
`order to avoid a disadvantage that 10% ofall terminals in a
`paging area accepting this paging message (and in the next
`paging messagethe next 10% would come, and so on) would
`seek to establish a point to point connection to get the emer-
`gency message content delivered, thus leading to arush to the
`resourceslikely to drive the system into an overloadsituation,
`the terminals are adapted to switch to the broadcast reception
`mode when detecting the specific identifier in the paging
`message, instead of establishing a point to point connection.
`According to embodiments, the advantages of both GSM
`techniques; cell broadcast service and paging mechanism,
`can be combined into an efficient emergency provisioning
`system.
`The method introduces a specific identifier such as
`E-TMSI, as previously described, as a generic identifier for
`indicating an emergencysituation. When a mobile receives a
`valid E-TMSI, it does not establish a PtP connection. Instead
`it switches to Cell-Broadcast modeandstarts to monitor the
`Cell-Broadcast Notification channels for emergency infor-
`mation contents. The E-TMSI may be formed in different
`ways, but all are a priori known as E-TMSIto the terminal.
`In accordance with one or more of the embodiments, not
`only one specific identifier such as only one E-TMSI may be
`provided but a group of two or more specific identifiers may
`be provisioned. The presence of a group of E-TMSI allows
`the following options.
`A first specific identifier, first E-TMSI, will activate the
`Cell-Broadcast Modein the terminal for an infinite time, i.e.
`the user has manually to disable the service. The terminal will
`hence start to continuously receive all cell broadcast mes-
`sages until manual switch-off.
`A second E-TMSI of another form or bit content will
`activate the Cell-Broadcast Modein the terminalfor a defined
`time (e.g. 1 hour) only, and then the terminal de-activates the
`cell-broadcast mode autonomously. This shall enable battery
`saving, and can be used if the emergencyis predictably of a
`limited severity.
`A third E-TMS]of another form or bit content can be used
`
`law
`to segregate groups of users, e.g. medical personal,
`enforcementstaff etc. The use of this E-TMSIcan be used to
`distribute specific information to specific groups.
`Whena groupofspecific identifiers exists, the network will
`select a specific identifier depending on the type of emer-
`gencyor the content of the information to be broadcast, and
`will includethe selected identifier into the paging message or
`messages transmitted in the cell or cells.
`In this embodiment, a group of TMS] codesis introduced,
`which are used as specific identifiers or E-TMSI. The termi-
`nal has a priori knowledge of the valid E-TMSI set and
`refrains from establishing an individual physical and logical
`Channel whenreceiving a paging message which includes
`oneofthese specific identifiers. Instead thereof, the reception
`ofan E-TMSIin a paging messageinitiates the cell broadcast
`service support autonomously in all terminals which have
`received the specially formatted paging message.
`The terminals then monitor the Cell Broadcast Notification
`Channel, and receive the emergency messageefficiently as a
`broadcast message.
`Advantageously, all needed technology is already present.
`The introduction of one or a subset of new TMSIvalues,
`which will cause a pre-defined mobile behaviour, allows the
`temporary use of the cell broadcast service, which service is
`usually disabled due to power consumption reasons.

`The system also includes permanentor removablestorage,
`such as magnetic and optical discs, RAM, ROM,etc. on
`whichthe process and data structures ofthe present invention
`can be stored and distributed. The processes can also be
`distributed via, for example, downloading over a network
`such as the Internet. The system can output the results to a
`display device, printer, readily accessible memory or another
`computer on a network.
