This TS defines the stage 2 description for the SIP-I based CS core network. The logical architecture for the SIP-I based CS core network is defined in TS 23.205.
This stage 2 shall cover the information flows between the GMSC server, MSC server and media gateways that are
required to support a SIP-I based Nc interface.
For the purposes of the present document, the Nc interface profile is based on ITU-T Q.1912.5 SIP-I profile C and is specified in TS 29.231. The Mc interface profile is based on ITU-T H.248.1 and is specified in TS 29.232.
Local Call Local Switch (LCLS) functionality is further specified in TS 23.284.
