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 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.
摘要翻译：跟踪应用服务器（AS）根据P2P群的状态指示内容缓存服务器（CCS）加入对等（P2P）群。跟踪器AS基于底层网络状况变化，对等节点加入或离开P2P群组，决定是否邀请CCS加入P2P群组，改变对等节点的流量状况，位置，能力或工作量（s）在群中。跟踪器AS向CCS发送邀请消息，指示感兴趣的内容和标识P2P群的对等节点的对等体列表。在从跟踪器AS接收到邀请消息时，CCS向跟踪器AS发送响应。跟踪器AS收到指示接受邀请的响应后，将CCS放入P2P群中，CCS使用P2P协议加入群组。

摘要： A method and apparatus for automatically discovering and retrieving content based on a content identity (ID) are disclosed. User agents and content control entities in the network interact for registering the content, discovering the content hosts and sources, and initiating and controlling the content session. A content name resolution handler (CNRH) is provided for mapping content IDs to network locations or addresses. Two or more content service provider networks may interconnect each other to discover and retrieve the content. A content request from a client device includes a content ID that uniquely identifies a content object. The content ID is resolved with a CNRH to obtain identity information of at least one content provider for serving the content request, and the content request is forwarded to the selected content provider. The content request may be routed to the selected content provider via IP multimedia subsystem (IMS) control plane entities.

摘要： A method and apparatus for managing content storage subsystems in a communications network are disclosed. The communications network is equipped with a plurality of content storage subsystems (240). The content storage subsystems (240) store local copies of content to facilitate the delivery and distribution of the content to wireless transmit/receive units, WTRUs (102b). The network, which is equipped with a proxy server (250) and an entry server (260), receives requests for content or general-purpose data referencing content and determines whether the content is stored in the storage subsystems (240). In addition, the network also performs content ingestion in order to store copies of the content in the storage subsystems (240) and content modification in order to move content from one storage location to another to achieve optimal content storage and distribution.

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： 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.
