ETSI ETSI TS 122 279 V13.0.0 (2016-01)63GPP TS 22.279 version 13.0.0 Release 131 Scope The present document specifies service requirements for Combining CS and IMS services using
27、 a CS speech or CS multimedia call in association with an IMS session. The IMS session may consist of one or more IMS services. Requirements for the following capabilities are included: - Radio capability exchange. - Terminal capability exchange. - E.164 number exchange. - Adding IMS session to an o
28、ngoing CS call. - Adding a CS call to an ongoing IMS session. - Supplementary services as they relate to CSICS. It is intended that the capabilities defined herein for CSICS shall support interoperability between different operator networks, and roaming. 2 References The following documents contain

The CS call and IMS session are established between the same participants. Combinational call: this
33、 is the name given to the service in which a circuit switched speech teleservice is enriched by adding an IMS session where both services (IMS session and CS call) are originated in one single UE and are terminated in another single UE.

34、3.0.0 Release 13Combinational Session: this is the name given to the service in which an ongoing IMS session between two users is enriched by adding a circuit switched based call. The individual service instances that form the combinational session are originated in a single UE and terminated in ano
35、ther single UE. CSICS capable UE: UE that supports Combinational Service. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply. Additional applicable abbreviations can be found in TR 21.905 1. CSICS Circuit Switched IMS Combinational Service 4 Introduction to
36、 Combinational Service Combinational services are applicable to both UTRAN and GERAN and enables the unidirectional or bi-directional exchange of PS data within the context of an IMS session A specific subscription for combinational services is not necessary. However, both users A and B shall as a m
37、inimum be provisioned with CS telephony (TS11) as well as for accessing the IMS. The existing address context is reused when the combined service is established, which makes the combined service simple to invoke for the user. 5 General requirements In addition to the existing IMS requirements 3, the
38、 following general requirements apply for CSICS: It shall be possible to establish a combinational service between two users within the same PLMN or within different PLMNs. It shall be possible to establish a combinational service between two users camped on identical or different RATs. It shall be
39、possible to establish a combinational service when roaming, assuming the visited operator supports GPRS roaming. The user (A or B party) shall only need to know one address in order to establish the combinational service. It shall be possible to add an IMS session to a CS speech call, thereby creati
40、ng a combinational call. It shall be possible to add a CS speech call to an IMS session, thereby creating a combinational session. It shall be possible to add an IMS session to a CS Multimedia call, thereby creating a combinational call. It shall be possible to add a CS Multimedia call to an IMS ses
41、sion, thereby creating a combinational session. The following two service modes will exist in regards to IMS registration depending on different UE implementations: 1) IMS pre established state: the CSICS capable UE performs the IMS registration at switch on. 2) IMS on demand state: the CSICS capabl
42、e UE performs the IMS registration: - to start the communication, or - to add a IMS session to an existing CS call. Interoperability between UEs that implement such different approaches shall be enabled. During a CS call it shall be possible to request establishment of the IMS session whether the in
43、vited UE is IMS registered or not. The invited user shall be able to accept or reject the IMS registration request. ETSI ETSI TS 122 279 V13.0.0 (2016-01)83GPP TS 22.279 version 13.0.0 Release 13A combinational service shall enable both unidirectional and bi-directional exchange of PS data within th
44、e context of the IMS session. 6 User experience of combinational services When one of the participating users terminates the CS call of a combinational service, the IMS session may continue. When one of the participating users terminates the IMS session of a combinational service, the CS call may co
45、ntinue. When the user A sends media to a user B, the user B can accept or reject the media (confirmation from the receiving party is needed) and vice versa. If media, or parts thereof, accepted by a user cannot be rendered by the UE simultaneously with the CS call, conflicts shall be resolved such t
46、hat the user is presented with: - CS speech with preference over IMS speech/audio; - IMS video and images with preference over CS video. It shall be possible to initiate a combinational service with user perceived simultaneous setup of IMS session and CS call. The CS call and IMS session can be esta
47、blished sequentially and on the failure of any of the setups the user may be prompted to decide whether to continue. The terminating user shall be able to accept or reject CS call or IMS session independently. 7 Service Capability Detection 7.1 General The Service Capability Detection may indicate t
48、o the user that the UEs have interoperable CSICS capability and that the access network(s) have the necessary network functionality to carry the combinational service. The detection of the capabilities of the recipient terminal and the operators“ networks shall ensure that information is updated in
49、case of change of terminal. An operator should have the mechanism to inhibit the capability check, or at least indicate to UE that it should not be performed. Note: An operator may want to inhibit the capability check for CSICS in order to optimise the usage of radio resources. It shall be possible for the (CSICS capable) UEs to have the information, prior to initiating a combinational service, regarding the type of capabilities, which are jointly supported by both UEs, without user intervention. Due to the handover of the participating users to an access
