The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should
33、the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater in
34、dicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document.

35、0 (2018-07)73GPP TS 25.419 version 15.0.0 Release 151 Scope The present document specifies the Service Area Broadcast Protocol (SABP) between the Cell Broadcast Centre (CBC) and the Radio Network Controller (RNC). It fulfils the CBC - RNC communication requirements specified in TS 23.041 5 and is de
36、fined over the Iu-BC reference point. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific
37、. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as

41、ation“. 3 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: Elementary Procedure: SABP consists of Elementary Procedures (EPs). An Elementary Procedure is a unit of interaction between the CN (CBC) and the RNC. These EP
42、s 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 relevant EP description. Unless otherwise stated by the restrictions, the EPs may be invoked independently of each o
43、ther as stand alone procedures, which can be active in parallel. Examples on using several SABP EPs together with each other and EPs from other interfaces can be found in reference TR 25.931 4. An EP consists of an initiating message and possibly a response message. Two kinds of EPs are used: ETSI E
44、TSI TS 125 419 V15.0.0 (2018-07)83GPP TS 25.419 version 15.0.0 Release 15- 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 ind
45、icates that the elementary procedure successfully completed with the receipt of the response. Unsuccessful - A signalling message explicitly indicates that the EP failed. - On time supervision expiry (i.e. absence of expected response). Class 2 EPs are considered always successful. Message Reference
46、: This is defined as consisting of the following parameters: Message Identifier, Serial Number, and SAI (Service Area Identifier). 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: CBC Cell Broadcast Centre CBS Cell Broadcast Service CN Core Network EP El
47、ementary Procedure FP Frame Protocol PDU Protocol Data Unit RNC Radio Network Controller SA Service Area SABP Service Area Broadcast Protocol 4 General The protocol described in the present document is the protocol between CN (CBC) and RNC needed for the CBC Application. The CBC Application is descr
48、ibed in TS 23.041 5. 4.1 Procedure Specification Principles The principle for specifying the procedure logic is to specify the functional behaviour of the RNC exactly and completely. The CN functional behaviour is left unspecified. The following specification principles have been applied for the pro
49、cedure text in clause 8: - 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 appropriate cause value.
