38、d within the Cell Broadcast area. A CBS message may contain information such as road traffic or weather information, originating from a Cell Broadcast Entity (CBE) communicating with the CBC (see 3GPP TS 23.041 1). ETSI ETSI TS 148 049 V14.0.0 (2017-04)83GPP TS 48.049 version 14.0.0 Release 14CBS me
39、ssage reference: Uniquely identifies a CBS message by the four elements: Message Identifier, Serial Number, Cell Identifier and Channel Indicator. Cell Broadcast area: An area comprising of one or more cells in which the CBS message or the emergency message is broadcasted. A Cell Broadcast area is a
40、lways contained within a BSC area (see 3GPP TS 23.002 14). CBS message operational state: A cell in CBS message operational state is able to broadcast CBS messages. Emergency message: A warning message conveying a small amount of data to indicate the imminent occurrence of an emergency such as earth
41、quake, tsunami etc. The emergency message is broadcasted to mobile stations in idle mode, packet idle mode and dedicated mode (see 3GPP TS 44.018 12) and to mobile stations in packet transfer mode and dual transfer mode (see 3GPP TS 44.060 13) located within the Cell Broadcast area. Emergency messag
42、e operational state: A cell in emergency message operational state is able to broadcast emergency messages. Emergency message reference: Uniquely identifies an emergency message by the three elements: Message Identifier, Serial Number and Cell Identifier. Elementary Procedure: CBSP consists of Eleme
43、ntary Procedures (EPs). An Elementary Procedure is a unit of interactions between the CBC and the BSC. These EPs are defined separately and are intended to be used to build up complete sequences in a flexible manner. If the independence between some EPs is restricted, it is described under the relev
44、ant EP description. Unless otherwise stated by the restrictions, the EPs may be invoked independently of each other as stand alone procedures, which can be active in parallel. Support of parallel procedures in the BSC is optional. An EP consists of an initiating message and possibly a response messa
45、ge. Two kinds of EPs are used: - Class 1: Elementary Procedures with response (success or failure). - Class 2: Elementary Procedures without response. For Class 1 EPs, the types of responses can be as follows: Successful - A signalling message explicitly indicates that the EP is successfully complet
46、ed. Unsuccessful - A signalling message explicitly indicates that the EP failed. - On time supervision expiry (i.e. absence of expected response). Class 2 EPs are always considered as successful. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: BSC Base

48、 TS 148 049 V14.0.0 (2017-04)93GPP TS 48.049 version 14.0.0 Release 144 General 4.1 Procedure Specification Principles The principle for specifying the procedure logic is to specify the functional behaviour of the BSC exactly and completely. The CBC functional behaviour is left unspecified. The foll
49、owing specification principles have been applied for the procedure text in clause 7: - The procedure text discriminates between: 1) Functionality which “shall“ be executed: - The procedure text indicates that the receiving node “shall“ perform a certain function Y under a certain condition. If the receiving node supports procedure X but cannot perform functionality Y requested in the REQUEST message of a Class 1 EP, the receiving node shall respond with the message used to report unsuccessful outcome for this procedure, containing an
