摘要： A method and apparatus are described for synchronizing mobile station (i.e., wireless transmit/receive unit (WTRU)) media flows during a collaboration session. Inter-WTRU transfer request messages, flow addition request messages and session update request messages may be exchanged between a plurality of WTRUs and a session continuity control application server (SCC-AS). Each of the messages may include a session description protocol (SDP) attribute line containing time synchronization information (e.g., a presentation time offset (PTO) information element (IE), a media flow group identity (ID) and a synchronization tolerance IE). The SCC-AS may update the time synchronization information and include the updated information in messages it sends to the WTRUs, which may re-synchronize their respective media flows based on the updated time synchronization information.

摘要： Techniques for inter-user equipment (UE) transfer (IUT) are disclosed. An application server receives an IUT request for transfer of a media session toward at least one UE such that a media stream is played by at least two UEs that are geographically separated after the transfer. The application server triggers inter-destination media synchronization (IDMS) for group synchronization of the media session among the UEs. The media stream may be anchored at a media server, and a media synchronization application server for the IDMS may be running at the media server. Alternatively, the media stream may be anchored at a media resource function (MRF), and a media synchronization application server for the IDMS may be running at the MRF.

摘要： A tracker application server (AS) instructs a content cache server (CCS) to join a peer-to-peer (P2P) swarm based on the status of the P2P swarm. The tracker AS determines whether to invite a CCS to join the P2P swarm be based on an underlying network condition change, a peer node joining or leaving the P2P swarm, change(s) in traffic condition, location, capability or workload of the peer node(s) in the swarm. The tracker AS sends an invitation message to the CCS, indicating the content of interest and a peer list identifying the peer nodes of the P2P swarm. Upon receiving the invitation message from the tracker AS, the CCS sends a response to the tracker AS. Upon receiving a response indicating the acceptance of the invitation, the tracker AS puts the CCS into the P2P swarm, and the CCS joins the swarm using a P2P protocol.

摘要： A method and apparatus for interworking between a mobile network operator and an application provider are disclosed. A network application function (NAF) may be co-located with an OpenID provider such that an application server may communicate with the NAF to access a home subscriber server (HSS) via a bootstrapping server function (BSF). The interfaces between BSF and HSS, and between BSF and NAF may be enhanced to carry information that is available through Sh interface between the application server and the HSS. When the WTRU is roaming in a visited network, the application server may communicate with the visited network for charging and policing for serving the service request from the WTRU. The application server may be co-located with an NAF, and may authenticate the WTRU using Generic Bootstrapping Architecture, and may communicate with a BSF in a home network via an eZn-proxy function to access an HSS.

摘要： A method and apparatus for performing session release are provided. For a transferred communication session between a plurality of wireless transmit/receive units (WTRUs) and a remote device, wherein at least one of the WTRUs performs the transferred communication session in association with a first Internet Protocol Multimedia Subsystem (IMS) and at least one other of the WTRUs performs the transferred communication session in association with a second IMS, session release may include releasing the transferred communication session, a portion thereof, one or more of the WTRUs, or a collaborative session associated with the transferred communication session while maintaining service continuity. Any one of the plurality of WTRUs or the remote device may initiate the session release by transmitting a release request. Any one of the plurality of WTRUs may control the transferred communication session and may modify or reject a release request.
