36、al Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by t

37、he 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 indicates TSG approved document under change control. y the second digit is increm

38、ented 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. 1 Scope This 3GPP Technical Specification (TS) specifies: 1. The interactions between the HSS (Home Subscri

39、ber Server) and the CSCF (Call Session Control Functions), referred to as the Cx interface. 2. The interactions between the CSCF and the SLF (Server Locator Function), referred to as the Dx interface. 3. The interactions between the SIP Core and the SIP database, referred to as the Cx interface, for

40、 the Mission Critical Commjnication Services, where this interface is named as AAA-1, as described in 3GPP TS 23.179 28. NOTE: In the 3GPP TS 23.179 xx the term SIP database is used for the HSS and the term SIP Core is used for the P-CSCF, the I-CSCF and the S-CSCF when compared to this specificatio

41、n. The IP Multimedia (IM) Subsystem stage 2 is specified in 3GPP TS 23.228 1 and the signalling flows for the IP multimedia call control based on SIP and SDP are specified in 3GPP TS 24.228 2. This document addresses the signalling flows for Cx and Dx interfaces. This document also addresses how the

42、 functionality of Px interface is accomplished. The Presence Service Stage 2 description (architecture and functional solution) is specified in 3GPP TS 23.141 10. 2 References 1 3GPP TS 23.228: “IP Multimedia (IM) Subsystem Stage 2“. 2 3GPP TS 24.228: “Signalling flows for the IP multimedia call con
