ETSI ETSI TS 125 453 V5.6.0 (2003-06) 7 3GPP TS 25.453 version 5.6.0 Release 5 1 Scope The present document specifies the Positioning Calculation Application Part (PCAP) between the Radio Network Controller (RNC) and the Stand-alone A-GPS SMLC (SAS). It fulfills the RNC-SAS communication
31、requirements specified in 6 and thus defines the Iupc interface and its associated signaling procedures. 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
32、 publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

37、 present document, the following terms and definitions apply: Standalone A-GPS SMLC (SAS): logical node that interconnects to the RNC over the Iupc interface via the PCAP protocol An SAS performs the following procedures: - provide GPS related data to the RNC; ETSI ETSI TS 125 453 V5.6.0 (2003-06) 8
38、 3GPP TS 25.453 version 5.6.0 Release 5 - performs the position calculation function for UE assisted GPS. Elementary Procedure: PCAP consists of Elementary Procedures (EPs) An Elementary Procedure is a unit of interaction between the RNC and the SAS. An EP consists of an initiating message and possi
39、bly a response message. 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 eleme
40、ntary procedure successfully completed with the receipt of the response. Unsuccessful: - A signalling message explicitly indicates that the EP failed. Class 2 EPs are considered always successful. Information Exchange Context: Information Exchange Context is created by the first Information Exchange
41、 Initiation Procedure initiated by the RNC and requested from the SAS The Information Exchange Context is deleted by the Information Exchange Termination or the Information Exchange Failure procedure when there is no more Information Exchange to be provided by the RNC to the SAS. The Information Exc
42、hange Context is identified by an SCCP connection as, for Information Exchanges, only the connection oriented mode of the signalling bearer is used. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: A-GPS Assisted GPS ASN.1 Abstract Syntax Notation One CN

45、 25.453 version 5.6.0 Release 5 4 General 4.1 Procedure Specification Principles The principle for specifying the procedure logic is to specify the functional behaviour of the SAS exactly and completely. The RNC functional behaviour is left unspecified. The following specification principles have be
46、en applied for the procedure 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
47、 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. 2) Functionality which “shall, if supported“ be executed: - The procedure
48、 text indicates that the receiving node “shall, if supported,“ perform a certain function Y under a certain condition. If the receiving node supports procedure X, but does not support functionality Y, the receiving node shall proceed with the execution of the EP, possibly informing the requesting no
49、de about the not supported functionality. - Any required inclusion of an optional IE in a response message is explicitly indicated in the procedure text. If the procedure text does not explicitly indicate that an optional IE shall be included in a response message, the optional IE shall not be included. 4.2 Forwards and Backwards Compatibility The forwards and backwards compatibility of the protocol is assured by mechanism where all current and future messages, and IEs or groups of related IEs, include Id and criticality fields that are coded in
