Digital cellular telecommunications system (Phase 2+) (GSM); Universal Mobile Telecommunications System (UMTS); LTE; Signalling flows for the session setup in the IP Multimedia core network Subsystem (IMS) based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP); Stage 3 (3GPP TR 24.930 version 15.0.0 Release 15)
The present document gives examples of the session setup in the IM CN subsystem based on SIP and SDP.
These signalling flows provide detailed signalling flows, which expand on the overview information flows provided in
3GPP TS 23.228 [2]. The flows focus on a basic session setup, i.e. no flows will be provided for topology hiding, for
sessions with IBCF involved or for sessions having certain features.
