17、Technical Specification (TS) was produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) under work item DTS/TISPAN-02051-NGN-R2 and originally intended to be published as ETSI TS 182 007. It was transferred to the 3rd Ge
18、neration Partnership Project (3GPP) in December 2007. 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 will be re-released by the TSG with an identifying cha
19、nge 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 second digit is incremented for all changes of subst
20、ance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The present document describes Voice Call Continuity functionalities for TISPAN Release 2. Scope of the work is to endorse t
21、he current 3GPP Release 7 stage 2 solution of VCC (described in the TS 23 206). ETSI ETSI TS 123 507 V8.0.0 (2007-12) 5 3GPP TS 23.507 version 8.0.0 Release 8 1 Scope The present document provides the ETSI TISPAN endorsement of 3GPP TS.23.206 3 “ Voice Call Continuity (VCC) between Circuit Switched
22、(CS) and IP Multimedia Subsystem (IMS); Stage 2: Release 7. The current VCC solution explained in the TS.23.206 is essentially defined for a core IMS provider that is a mobile operator (that has also CS domain). In Informative Annex ZA theres is a possible scenario how the solution can be extended t
23、o a generic IMS operator (e.g. when fixed network operator and CS mobile network operator are separate organisations). 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

ETSI ETSI TS 123 507 V8.0.0 (2007-12) 7 3GPP TS 23.507 version 8.0.0 Release 8 Annex ZA (informative): A possible scenario to adapt 3GPP VCC to multi-operator scenario ZA.1 Introduction The present annex
38、 defines additional concepts of VCC service provisioning in order to support VCC multi -operator scenario where IMS and CS domain belong to different operators; i.e. when the user“s IMS services and the user“s CS services are under the control of different home operators. For the purposes of the pre
39、sent annex, the concepts given in TS 23.206 iii and the ones defined in the main body of this specification are still to be applied. ZA.2 Definitions, symbols and abbreviations The text in clause 3 of iii applies, with the following modifications. ZA.2.1 Definitions The text in clause 3.1 of iii app
40、lies. Moreover the following definitions apply: VCC single-operator scenario: VCC scenario where IMS and CS domain belong to the same operator VCC multi -operator scenario: VCC scenario where IMS and CS domain belong to different operators; i.e. when the user“s IMS services and the user“s CS service
41、s are under the control of different home operators ZA.3 VCC Concepts ZA.3.1 General The description enhances the VCC general concepts specified in subclause 4.1 of iii. Two operators providing CS and IMS access respectively may co-operate to provide VCC together for their subscribers. 3GPP VCC can
42、be applied in this kind of scenario under appropriate conditions. However there are a number of issues to be agreed between the parties starting from the ownership of the subscriber (and SIM card). One thing to agree is if the subscriber can have IMS services also in the CS operator network. Two sim
43、ultaneous or just different types of IMS registrations may not be supported by terminals. The HSS depicted in the VCC architecture can be split into HLR and IMS part of HSS. CS operator manages the CS subscription and the HLR data and is responsible for the related authentication. IMS operator manag
44、es the IMS subscription and the IMS part of HSS as well as authentication to IMS. The operators may agree that MAP protocol is used towards HLR e.g. to query the user status. CAMEL control is made by the CS operator as agreed with the IMS operator to route originating calls to IMS for anchoring and
45、chosen services. The operators need to agree on the way the address information is carried so that CS Adaptation function of the VCC Application is able to restore the originally provided called party address. Otherwise ETSI ETSI TS 123 507 V8.0.0 (2007-12) 8 3GPP TS 23.507 version 8.0.0 Release 8 i
46、nter-operator interface would be needed between CAMEL gsmSCF and VCC Application. No change is needed to TS 23.206. The applied subscriber addressing and routing scheme shall be designed. It may be required to use two different public addresses for CS and IMS respectively. It should be decided if si
47、ngle address is wished and if that is the case, which operator holds those addresses i.e. whether IMS or CS operator network gets the incoming traffic. All VCC enabled calls shall be routed via IMS operator network even if they would first enter the CS operator network. VCC Domain Selection Function
48、 in the IMS operator network decides if the IMS or CS domain is used for the terminating call. VCC Application shall be aware of subscribers addresses in CS and IMS. If single subscriber address is wished to be shown as calling party address, a particular service is needed in IMS operator network to
49、 achieve this. This is outside the scope of VCC. It should be noted that the regulatory requirements may prohibit changing the actual calling party address carried in signalling. VCC Application may contain different type of policies regarding CS and IMS use but all details of those are out of scope of standardization. VCC Application may store the policy to the terminal by device management means as specified for 3GPP VCC. The VCC service model is distributed and e.g. call forwarding s
