ETSI ETSI TS 129 231 V13.0.0 (2016-01)63GPP TS 29.231 version 13.0.0 Release 131 Scope The present document describes the protocols to be used when SIP-I is optionally used as call control protocol in a 3GPP CS core network on Nc interface, see 3GPP TS 23.2

35、31 1. The SIP-I protocol operates between (G)MSC servers. The SIP-I architecture consists of a number of protocols. The following types of protocols are described: call control protocol, resource control protocols and user plane protocol for this architecture. The architecture complies with the requ

36、irements imposed by 3GPP TS 23.231 1 and TS 23.153 2. Interworking of SIP-I on Nc to external networks is described by TS 29.235 3. The present document is valid for a 3rdgeneration PLMN (UMTS) complying with Release 8 and later. 2 References The following documents contain provisions which, through

37、 reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
