Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet- Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

Abstract This document provides an overview by means of signalling flows of the methods by which 3GPP wishes to uses SIP for the specification of the IP Multimedia CN subsystem for the purposes of registering user equipment. 3gpp Informational - Expires August 2001 1 3GPP IP Multimedia CN Subsystem February 2001 - Registration flows Table of Contents Status of this Memo................................................1 Abstract...........................................................1 Conventions used in this document..................................3 Introduction.......................................................3 Security Considerations............................................3 References.........................................................4 Author's Addresses.................................................4 Full Copyright Statement...........................................5 Annex A............................................................5 3gpp Informational - Expires August 2001 2 3GPP IP Multimedia CN Subsystem February 2001 - Registration flows Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC-2119 [2]. 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: ô3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Service requirements for the IP Multimedia Core Network Subsystem (Stage 1)ö. r d TS 23.228: ô3 G e neration Partnership Project; Technical Specification Group Services and System Aspects; IP Multimedia (IM) Subsystem - Stage 2ö. TS 24.228: ô3rd Generation Partnership Project; Technical Specification Group Core Network; Signalling flows for the IP multimedia call control based on SIP and SDPö. TS 24.229: ô3rd Generation Partnership Project; Technical Specification Group Core Network; IP Multimedia Call Control Protocol based on SIP and SDPö. TS 23.218: ô3rd Generation Partnership Project; Technical Specification Group Core Network; IP Multimedia (IM) Session Handling; IP Multimedia (IM) call modelö. and these may be found as described in draft-3GPP-collaboration- 00.txt This document describes how 3GPP intend to apply SIP to the registration of user equipment on the IM CN subsystem by means of diagrams showing the flow and contents of signalling information.
