IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web

Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN), and is now submitted for the ETSI standards
Membership Approval Procedure.
Introduction
The present document describes Voice Call Continuity functionalities for TISPAN Release 2. Scope of the work is to
endorse the current 3GPP Release 7 stage 2 solution of VCC (described in 3GPP TS 23.206).

1 Scope
The present document provides the ETSI TISPAN endorsement of 3GPP TS 23.206 [2] "Voice Call Continuity (VCC)
between Circuit Switched (CS) and IP Multimedia Subsystem (IMS); Stage 2: Release 7".
The current VCC solution explained in 3GPP TS.23.206 is essentially defined for a core IMS provider that is a mobile
operator (that has also CS domain). In annex ZA there is a possible scenario showing how the solution can be extended
to a generic IMS operator (e.g. when fixed network operator and CS mobile network operator are separate
organizations).

References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following

For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,
the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the
reference should, as far as possible, remain valid for the expected life of the document. The reference shall include the
method of access to the referenced document and the full network address, with the same punctuation and use of upper
case and lower case letters.
