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： Embodiments contemplate the movement of mobile node (MN) from a first access network to a second access network, while in communication with a CDN server (e.g. a surrogate providing a multimedia streaming session). The server selection may become sub-optimal as a result of this movement. A first CDN may learn about MN mobility event via the MN, an access network node, the server, or another node. The first CDN may trigger reselection by upstream CDN by sending a CDNI reselection request message, including information for the upstream CDN to perform request routing for the MN with the specified content, at a different location. The upstream CDN may perform the request routing procedure. The upstream CDN may return the request routing result to first CDN. The initial server may send a redirection message back to the application, which may interpret the message and continue streaming from a different server.
摘要翻译：实施例考虑移动节点（MN）从第一接入网络移动到第二接入网络，同时与CDN服务器（例如提供多媒体流会话的代理）进行通信。作为这种移动的结果，服务器选择可能变得不合适。第一个CDN可以通过MN，接入网络节点，服务器或另一个节点了解MN移动性事件。第一CDN可以通过发送CDNI重选请求消息来触发上游CDN的重选，该CDNI重选请求消息包括用于上游CDN的信息，以在具有指定内容的MN执行请求路由，在不同的位置。上行CDN可以执行请求路由过程。上游CDN可以将请求路由结果返回到第一个CDN。初始服务器可以向应用发送重定向消息，该消息可以解释消息并从不同的服务器继续流。

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.
