ETSI ETSI TS 129 228 V13.1.0 (2016-04)73GPP TS 29.228 version 13.1.0 Release 131 Scope This 3GPP Technical Specification (TS) specifies: 1. The interactions between the HSS (Home Subscriber Server) and the CSCF (C

39、all 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 the Mission Critical Commj

40、nication 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 specification. The IP Multimedia (IM) S

41、ubsystem 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 functionality of Px interf

42、ace is accomplished.
