IMS services interaction

Résumé

In their LS in S1-094250 / S2-100041, SA1 reminded that the following requirement has been specified in TS 22.228, clause 5: "Within each IP multimedia session, one or more IP multimedia applications shall be supported. It shall be possible to support multiple IP multimedia applications to efficiently provide a coherent and consistent IP multimedia service experience. Such support involves identifying which applications are invoked per subscriber, understanding the appropriate order of the set of applications, and resolving application interactions during the session." CT1 has expressed the need to have stage-2 requirements specified for IMS services interactions before they proceed with specifying a solution to avoid conflicting interactions between services provided by different Application Servers. Additionally, text in clause 4.16.1 seems to imply that MMTel functionalities can only be provided by a single AS, which is in contradiction with TS 24.173 clause 4.1A.2
