The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it wi
29、ll be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the
30、second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document.

31、e Voice call continuity allows users to move between the CS domain and the IP Connectivity Access Network (e.g., WLAN interworking) with home IM CN subsystem functionality. The present document provides the protocol details for voice call continuity between the IP Multimedia (IM) Core Network (CN) s
32、ubsystem based on the Session Initiation Protocol (SIP) and the Session Description Protocol (SDP) and the protocols of the 3GPP Circuit-Switched (CS) domain (CAP, MAP, ISUP, BICC and the NAS call control protocol for the CS access). This document makes no VCC specific enhancements to SIP, SIP event
33、s or SDP, beyond those specified in 3GPP TS 24.229 7. The present document is applicable to User Equipment (UEs), Application Servers (AS) and Media Gateway Control Functions (MGCF) providing voice call continuity capabilities. 2 References The following documents contain provisions which, through r
34、eference 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. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest versio
