    Abstract: An apparatus and method are described for sponsoring service and preferential traffic handling, (i.e., data connectivity) by wireless transmit/receive units (WTRUs). A first WTRU may initiate user sponsoring of a second WTRU via an application server (AS). The first WTRU may receive a service trigger from the AS and forward the service trigger to the second WTRU. The second WTRU may then initiate a sponsored session with the AS using the service trigger in order to receive a service from the AS. The first WTRU may also request the AS to transfer a credit to the second WTRU. The AS may establish a direct communication link with a charging system including an online charging function (OCF) and a charging data function (CDF). The AS may send a request to a network to provide preferential traffic handling needed to deliver content to the second WTRU.

    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.

    Abstract: 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.

    Abstract: A multi-hypothesis rate adaptation technique may be performed for one or more wireless multimedia streaming scenarios. Managing a multi-media 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: 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.
