ETSI ETSI TS 122 279 V15.0.0 (2018-07)63GPP TS 22.279 version 15.0.0 Release 151 Scope The present document specifies service requirements for Combining CS and IMS services using a CS speech or CS multimedia call in association with an IMS session. The IMS session may consist of one or
29、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 ongoing CS call. - Adding a CS call to an ongoing IMS session. - Supplementary services as they relate to CSIC
30、S. 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 provisions which, through reference in this text, constitute provisions of the present document. References a

34、ional service is created by adding one or more IMS session(s) to a CS call (or vice versa). The CS call and IMS session are established between the same participants. Combinational call: this is the name given to the service in which a circuit switched speech teleservice is enriched by adding an IMS
35、 session where both services (IMS session and CS call) are originated in one single UE and are terminated in another single UE. Combinational 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 indi
36、vidual service instances that form the combinational session are originated in a single UE and terminated in another single UE. CSICS capable UE: UE that supports Combinational Service. ETSI ETSI TS 122 279 V15.0.0 (2018-07)73GPP TS 22.279 version 15.0.0 Release 153.2 Abbreviations For the purposes
37、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 Combinational Service Combinational services are applicable to both UTRAN and GERAN and enables the unidirec
38、tional 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 minimum be provisioned with CS telephony (TS11) as well as for accessing the IMS. The existing address context
39、 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 following general requirements apply for CSICS: It shall be possible to establish a combinational service be
40、tween 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 possible to establish a combinational service when roaming, assuming the visited operator supports GPRS roami
41、ng. 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 creating a combinational call. It shall be possible to add a CS speech call to an IMS session, thereby creating a c
42、ombinational 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 session, thereby creating a combinational session. The following two service modes will exist in regards to IMS
43、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 capable UE performs the IMS registration: - to start the communication, or - to add a IMS session to an existing CS
44、 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 invited UE is IMS registered or not. The invited user shall be able to accept or reject the IMS registration re
45、quest. A combinational service shall enable both unidirectional and bi-directional exchange of PS data within the 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 continu
46、e. When one of the participating users terminates the IMS session of a combinational service, the CS call may continue. ETSI ETSI TS 122 279 V15.0.0 (2018-07)83GPP TS 22.279 version 15.0.0 Release 15When the user A sends media to a user B, the user B can accept or reject the media (confirmation from
47、 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 that the user is presented with: - CS speech with preference over IMS speech/audio; - IMS video and images wit
48、h 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 established sequentially and on the failure of any of the setups the user may be prompted to decide whether to co
49、ntinue. 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 to 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 case of change of terminal. An operator should have the mechanism to inh
