    Abstract: 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.

    Abstract: Techniques for inter-user equipment (UE) transfer (IUT) are disclosed. An application server may receive an IUT request for transfer of a media session toward at least one initial UE such that the media session is to be played by at least two target UEs. The server may determine eligibility for IUT with group synchronization based on the request. The server may send a message to the initial UE that IUT with group synchronization is not allowed on a condition that IUT with group synchronization is not allowed. Further, the server may trigger inter-destination media synchronization (IDMS) for group synchronization of media sessions among the UEs on a condition that IUT with group synchronization is allowed. The media sessions may include a first media session and second media session. The media stream may be played by at least two UEs that are geographically separated after the transfer.

    Abstract translation: 公开了用于用户间设备（UE）传送（IUT）的技术。 应用服务器可以接收针对至少一个初始UE传输媒体会话的IUT请求，使得媒体会话将被至少两个目标UE播放。 服务器可以根据请求确定具有组同步的IUT的资格。 服务器可以向初始UE发送消息，在不允许具有组同步的IUT的条件下，不允许具有组同步的IUT。 此外，在允许具有组同步的IUT的条件下，服务器可以触发用于UE之间的媒体会话的组同步的目的地间媒体同步（IDMS）。 媒体会话可以包括第一媒体会话和第二媒体会话。 媒体流可以由传输之后的地理上分离的至少两个UE播放。

    Abstract: 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.

    Abstract: 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. The content storage subsystems store local copies of content to facilitate the delivery and distribution of the content to wireless transmit/receive units, WTRUs. The network, which is equipped with a proxy server and an entry server, receives requests for content or general-purpose data referencing content and determines whether the content is stored in the storage subsystems. In addition, the network also performs content ingestion in order to store copies of the content in the storage subsystems and content modification in order to move content from one storage location to another to achieve optimal content storage and distribution.

    Abstract: Systems, methods, and instrumentalities are provided to implement content caching. An entity running an external application (EA) may establish a connection between the EA and a centralized cloud controller (CCC) to access a service on the CCC. The EA may receive credentials for access to the service. The connection between the EA and the CCC may be established over a first interface. The EA may send to the service on the CES a query for an available small cell network (SCN) storage. The EA may receive from the service on the CES reply comprising a link to an allocated SCN storage. The EA may ingest one or more contents using the link in the allocated SCN storage. A wireless transmit/receive unit (WTRU) may receive the cached content from an edge server in a small cell network.

    Abstract: 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.
