A:有限制,我們實(shí)際播出的內(nèi)容最大字?jǐn)?shù)為80-120個(gè)字(包括標(biāo)點(diǎn))。小區(qū)廣播理論值上每條信息最大可以發(fā)送600字,但是因?yàn)楦骺钍謾C(jī)接收性能不一致,如三星的部分型號(hào)手機(jī)只能接收40字,顯示不完整,所以取較低的發(fā)送字?jǐn)?shù)。 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 geographical 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 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 CBS''s coverage requirements. The CBS message comprises of 82 octets, which, using the default character set, equates to 93 characters. 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 identify and ignore re-broadcasts 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 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 catchment 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 channel (see [8]). 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 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, 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.
