Abstract: 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.

Abstract: A method and apparatus are described for performing a selected Internet protocol (IP) traffic offload (SIPTO) procedure. A network node, (e.g., a mobility management entity (MME) or a serving general packet radio service (GPRS) support node (SGSN)), may receive a packet data network (PDN) connectivity request from a wireless transmit/receive unit (WTRU). A determination may be made to perform SIPTO at a local network, and the WTRU may perform a PDN release and reconnection procedure. The determination may be based on at least one of a closed subscriber group (CSG) identity (ID), a home evolved Node-B (HeNB) ID or a local network ID. An access network discovery and selection function (ANDSF) may be queried for IP interface selection (OPIIS) rules, a local access point name (APN) that supports per flow SIPTO at a local network, and IP flows that may be routed to the local APN.

Abstract: 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.

Abstract: Systems, methods, and instrumentalities are disclosed to provide pre-negotiation of a video codec. An IP multimedia subsystem (IMS) entity, such as a service centralization and continuity application server (SCC AS), may send a first session initiation protocol (SIP) message to a circuit switched domain entity via an IMS core network. The first SIP message may correspond to a video call in an on-going IP multimedia subsystem (IMS) session. The first SIP message may include one or more video codecs supported by the SCC AS and the UE associated with the video call. The SCC AS may receive a second SIP message from the circuit switched domain entity. The second SIP message may include the video codec, which may be one of the video codecs included in the first SIP message. The SCC AS may send the video codec to a user equipment (UE) associated with the video call.
