ETSI TS 129 228 specifies:
-
The interactions between the HSS (Home Subscriber Server) and the CSCF (Call Session Control Functions), referred to as the Cx interface.
-
The interactions between the CSCF and the SLF (Server Locator Function), referred to as the Dx interface.
-
The interactions between the SIP Core and the SIP database, referred to as the Cx interface, for 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 specification.
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 functionality of Px interface is accomplished.
The Presence Service Stage 2 description (architecture and functional solution) is specified in 3GPP TS 23.141 [10].
