33、 GSM O 1 .O4 i. 2 General description The CBS service is analogous to the Teletex service offered on television, in that like Teletex, it permits a number of unacknowledged general messages to be broadcast to all receivers within a particular region. CBS messages are broadcast to defined geographica
34、l areas known as cell broadcast areas. These areas may comprise of one or more cells, or may comprise the entire PLMN. Individual CBS messages will be assigned their own geographical coverage areas by mutual agreement between the information provider and the PLMN operator. CBS messages may originate
35、 from a number of Cell Broadcast Entities (CBEs), which are connected to the Cell Broadcast Centre. CBS messages are then sent from the CBC to the BTSs, in accordance with the CBSs coverage requirements. The CBS message comprises of 82 octets, which, using the default character set, equates to 93 ch
36、aracters. Up to 15 of these messages (pages) may be concatenated to form a macromessage. Each page of such macromessages will have the same message identifier (indicating the source of the message), and the same serial number. Using this information, the MS is able to identiSl and ignore re-broadcas
37、ts of already received messages. CBS messages are broadcast cyclically by the BTS at a frequency and for a duration agreed with the information provider. The frequency at which messages are repeatedly transmitted will be dependent on the information that they contain; for example, it is likely that
38、dynamic information such as road traffic information, will require more frequent transmission than weather information. The repetition period will also be affected by the desire for messages to be received by high speed mobiles which rapidly traverse cells. All suitably equipped mobiles within the c
39、atchment area of the transmitting BTS will be able to receive the broadcast messages, provided that they are switched on and in the idle state. CBS messages may be broadcast on two different cell broadcast channels, which are characterized by different QoS. A MS is always able to read the basic chan
40、nel (see SI). The reading of the extended channel may collide with other tasks of the MS. Therefore the probability of receiving a CBS message on the extended channel is smaller than on the basic channel. The reading of the extended channel for MSs is optional. The scheduling on the channels will be
41、 done independently. To permit mobiles to selectively display only those messages required by the MS user, CBS messages are assigned a message class which categorises the type of information that they contain and the language in which the message has been compiled. Through the use of appropriate MMI
42、, the user is then able to ignore message types that he does not wish to receive, e.g. advertising information or messages in an unfamiliar language. 3 Network Architecture The basic network structure of CBS is depicted by figure 1.

Figure 1 - - - - message transfer on link 1 is outside the scope of GSM Specifications; message transfer on link 2 is described in subclause 9.1; message transfer on link 3 is descr

45、l aspects of formatting CBS, including the splitting of a CBS message into a number of pages. 5 CBC Functionality As the CBC (and any originating point for cell broadcast short messages) is regarded as a node outside the PLMN, only the requirements placed upon the CBC by CBS functionality are specif
46、ied by this specification. The CBC may be connected to several BSCs. The CBC may be connected to several CBEs. The CBC shall be responsible for the management of cell broadcast short messages including: - allocation of serial numbers; - modif$ng or deleting messages held by the BSC; - initiating bro
47、adcast by sending fixed length cell broadcast short messages to a BSC for each language provided by the cell, and where necessary padding the message to a length of 82 octets see GSM 03.381; determining the set of cells/BTSs to which a message should be broadcast, and indicating within the Serial Nu
48、mber the geographical scope of each message; determining the time at which a message should commence being broadcast; - - - determining the time at which a message should cease being broadcast and subsequently instructing each BSC to cease broadcast of the message; determining the period at which br
49、oadcast of the message should be repeated; - ETSI 3GPP TS 03.41 version 7.4.0 Release 1998 9 ETSI TS 100 902 V7.4.0 (2000-09) - determining the cell broadcast channel, on which the message should be broadcast. To work efficiently on the interfaces, the BSC - which is normally controlling more than one cell of a broadcast area - should be used as a concentrator as far as CB message handling is concerned. Hence, the CBC should work on lists of cells when issuing CB related requests towards the BSC. 6 BSC Functionality The BSC shall interface to only one CB
