    摘要： A method and apparatus are described for providing a dynamic cache function in a network or cloud. A content cache server (CCS) and a lightweight CCS with a dynamic cache function may be deployed in the network or cloud. A tracker may be used to place dynamic cache peers in a peer list, and transmit the peer list to a wireless transmit/receive unit (WTRU). The peer list may include a single peer that is a dynamic cache peer allocated by the tracker to the WTRU, or at least two dynamic cache peers, with one additional “weight” parameter for each dynamic cache peer. The WTRU may connect to the dynamic cache peer with the largest “weight” parameter, and connect to a different dynamic cache peer in the peer list on a condition that the WTRU gets disconnected or gets bad service from the dynamic cache peer with the largest “weight” parameter.

    摘要： A method and apparatus for content identification, retrieval, and routing in the Internet are provided. In the method and apparatus, content is uniquely identified using an object identifier (OID), and the OID is used for routing and retrieving content in an Internet network. Further, in the method and apparatus, OID summarization based on one or more OIDs may be performed, in which Bloom filters are applied to a portion of the one or more OIDs. Furthermore, hash functions may be applied to network node identities to determine location resolver nodes associated with content.

    摘要： A method and apparatus for distribution and reception of content are disclosed. A quality function for a content object may be sent to intermediate cache proxy servers and/or a receiver(s). The quality function provides a functional relationship between at least two quality metrics for the content object so that a perceivable quality of the content object at a receiver may be estimated based on the quality function. The quality function may be represented by a polynomial series and/or a set of mean and standard deviation values. The quality function may be included in media presentation description (MPD) for Dynamic Adaptive Streaming over HTTP (DASH) streaming, or a session description protocol (SDP) message or a Real Time Control Protocol (RTCP) sender report for Real Time Streaming Protocol (RTSP) streaming.

    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.
