摘要： Systems, methods, and instrumentalities are disclosed for defining a network specialization mechanism that enables a better alignment between end users' usage profiles and their access networks. Conteni specialization of networks may be implemented as a preference o a particular SCN or network in terms of content. Such a network may, for example, cache in priority preferred content, provide preferential quality of service (QoS), or limit access to non-preferred content. A network may advertise its preference or content specialization to end users (e.g., so that end users can decide to attach to SCNs or networks with compatible preferences) and to other content networks (e.g., to influence content routing decisions or to negotiate partitioning of the specialization space). Such content specialization may apply to physical or virtual networks.

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： Methods, apparatus, systems, devices, and computer program products directed to enabling federation 200 of multiple independent networks 204A, 204B, 204C, 204D through hash-routing based peering (HRP) and/or summary-routing based peering (SRP) are provided. Pursuant to new methodologies and/or technologies provided herein the multiple independent networks self-organize, or otherwise assemble, as a federation of network peers. The network peers 204A, 204B, 204C, 204D cooperate to pool and/or merge resources to make available for the federation 200 a population of content objects. As members of the federation, each of the network peers undertakes responsibility for making available to other network peers a share of the population. The multiple independent networks establish connectivity and federate using an HRP protocol. Pursuant to the HRP protocol, the network peers allocate amongst themselves respective key ranges within a hash-value space of a hash function. The network peers employ an allocation strategy to guide allocation of the hash-value space. When one of the network peers 204C receives a content request 201 from a local end user 202, local router or another network, the network peer routes and/or forwards the content request over a backhaul or transit network 216C or any link not part of the peering network if the content request falls into the content-object population allocated to this peer. Alternatively, the network peer routes and/or forwards the content request 201 through another network peer for processing if a hash value calculated from the content request falls within a key range of a hash value space allocated to such network peer. Logically merging the multiple individual networks as a federation with the logically combined backhaul and/or caching resources of the network peers 204A, 204B, 204C, 204D, should result in an efficiency gain because of a higher cache-hit ratio, since the merged caching resources supports a larger population. Federating the multiple individual networks using the HRP protocol enables such logical merging of caching storage capacity and transit (or backhaul) transfer capacity of the multiple individual networks.
摘要翻译：提供的方法，设备，系统，设备和计算机程序产品通过基于散列路由的对等（HRP）和/或基于汇总路由的对等（SRP）来引导多个独立网络204A，204B，204C，204D的联合200 。根据本文提供的新方法和/或技术，多个独立网络自组织或以其他方式组装，作为网络对等体的联合。网络对等体204A，204B，204C，204D协作以对资源进行池和/或合并，使联合体200能够使用多个内容对象。作为联盟的成员，每个网络同行承担责任向其他网络对等体提供一部分人口。多个独立网络使用HRP协议建立连接和联合。根据HRP协议，网络对等体在哈希函数的哈希值空间内各自分配各自的密钥范围。网络对等体采用分配策略来引导散列值空间的分配。当网络对等体204C中的一个从本地终端用户202，本地路由器或另一网络接收到内容请求201时，网络对等体通过回程或转接网络216C或任何不是该网络的一部分的链路来转发和/或转发该内容请求如果内容请求落入分配给该对等体的内容对象总体中，则对等网络。或者，如果从内容请求计算的散列值落入分配给这样的网络对等体的散列值空间的关键范围内，则网络对等体路由和/或转发另一个网络对等体进行处理的内容请求201。作为联合的多个单独网络与网络对等体204A，204B，204C，204D的逻辑组合回程和/或缓存资源进行逻辑合并应导致由于更高的缓存命中率而导致的效率增益，因为合并缓存资源支持更大的人口。使用HRP协议联合多个单独的网络可以实现多个单独网络的缓存存储容量和传输（或回程）传输容量的逻辑合并。

摘要： A multi-hypothesis rate adaptation technique may be performed for one or more wireless multimedia streaming scenarios. Managing a multimedia streaming session may involve sending, by a client, a request for a first portion of content to a server. A response may be received from a proxy. The response may comprise the first portion of content and information associated with a second portion of content available via the proxy. A request may be sent to the proxy for the proxy to deliver the second portion of content to the client. A change in a parameter associated with the multimedia streaming session may be determined based on data received from the proxy. It may be determined to change a rate adaptation. A Wireless Transmit/Receive Unit (WTRU) may be configured to perform the rate adaptation.

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.

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).

摘要： Methods and apparatus are described for synchronizing a media presentation on a plurality of wireless transmit/receive units (WTRUs). A media session may be replicated from a first WTRU onto a second WTRU. The first WTRU may initiate a bookmark procedure to create a bookmark to obtain synchronized playout with the second WTRU. A suggested presentation offset in the bookmark may specify an offset in time from a bookmark created time to a bookmark presentation time at the first WTRU. The first WTRU may establish an Internet protocol (IP) multimedia subsystem (IMS) session with a packet switch stream (PSS) server. The media session may be replicated onto the second WTRU at a wall-clock time T, and the second WTRU may present an offset equal to T - bookmarkcreatedtime + bookmark offset - suggestedPresentationOffset from the beginning of a program in order to obtain synchronized media playout with the first WTRU.
