10、nes a call control protocol for use in the IP Multimedia (IM) Core Network (CN) 2 subsystem based on the Session Initiation Protocol (SIP), and the associated Session Description Protocol 3 (SDP). 4 The present document is applicable to: 5 - the interface between the User Equipment (UE) and the Call
11、 Session Control Function (CSCF); 6 - the interface between the CSCF and any other CSCF; 7 - the interface between the CSCF and an Application Server (AS); 8 - the interface between the CSCF and the Media Gateway Control Function (MGCF); 9 - the interface between the S-CSCF and the Media Resource Fu
12、nction Controller (MRFC) 10 - the interface between the CSCF and the Breakout Gateway Control Function (BGCF); 11 - the interface between the BGCF and the MGCF; 12 - the interface between the BGCF and any other BGCF; and 13 - the interface between the CSCF and an external Multimedia IP network. 14 W
13、here possible the present document specifies the requirements for this protocol by reference to specifications 15 produced by the IETF within the scope of SIP and SDP. Where this is not possible, extensions to SIP and SDP 16 are defined within the present document. The document has therefore been st
14、ructured in order to allow both 17 forms of specification. 18 NOTE 1: This document assumes the existence of the Go interface between the ICN Bearer Control Point 19 and the P-CSCF. However, since the Go interface is not supported in the MMD Revision 0, the 20 procedures that are dependent on the Go
15、 interface are not mandatory. This also pertains to the 21 Service Based Local Policy (SBLP) which is also not supported in the MMD Revision 0. 22 NOTE 2: The present document covers only the usage of SIP and SDP to communicate with the entities of 23 the IM CN subsystem. It is perfectly possible, a
16、nd not precluded, to use only the capabilities of 24 the IP Connectivity Network to allow a terminal containing a SIP UA to communicate with SIP 25 servers outside the IM CN subsystem, and therefore utilise the services provided by those SIP 26 servers. Such usage is outside the scope of the present
17、 document. 27 2 References 28 The following documents contain provisions which, through reference in this text, constitute provisions of the 29 present document. 30 For non-specific 3GPP references the latest Release 5 applies. 31 References are either specific (identified by date of publication, ed
