摘要
A communication system facilitates notification of a controller User Equipment (UE) about the changes of session description in a collaborative session by subscribing to a Session Continuity Controller (SCC) Application Server (AS). First, controller UE subscribes to its dialog event package with the SCC AS. Second, SCC AS maintains several dialogs with controller UE, controllee UE(s) and remote UEs within the collaborative session. Third, when there is an updates in the session description of UEs in the collaborative session, SCC AS notifies the controller UE about the change in a SIP NOTIFY request that is constructed by having an XML body with a session description element containing the Session Description Protocol (SDP) of all of the controllee UEs and remote UEs, including media lines and related information such as as the IP addresses of the UEs.
