Introduction The Third Generation Partnership Project (3GPP) is described in draft-3GPP-collaboration-00.txt. The IP Multimedia CN Subsystem provides session control capabilities to user equipment accessing the system using the General Packet Radio Service, which supports the use of IP and applications that can use IP. The IP Multimedia CN subsystem will be defined in a number of 3GPP documents. Documents currently under development include: TS 22.228: "3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Service requirements for the IP Multimedia Core Network Subsystem (Stage 1)". r d TS 23.228: "3 G e neration Partnership Project; Technical Specification Group Services and System Aspects; IP Multimedia (IM) Subsystem - Stage 2". TS 24.228: "3rd Generation Partnership Project; Technical Specification Group Core Network; Signalling flows-] {+not available; please do not ask+} for [-the IP multimedia call control based on SIP and SDP". TS 24.229: "3rd Generation Partnership Project; Technical Specification Group Core Network; IP Multimedia Call Control Protocol based on SIP and SDP". TS 23.218: "3rd Generation Partnership Project; Technical Specification Group Core Network; IP Multimedia (IM) Session Handling; IP Multimedia (IM) call model". and these may be found as described in draft-3GPP-collaboration- 00.txt This document describes how 3GPP intend to apply SIP to the establishment of sessions between user equipment on the IM CN subsystem by means of diagrams showing the flow and contents of signalling information.
