  • Patent number: 10003933
    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.

  • Patent number: 9854009
    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 synchronized by a first wireless transmit/receive unit (WTRU) creating a networked bookmark for a media program at a bookmark-created time; the first WTRU presenting the media program at a bookmark-presentation time, wherein the first WTRU includes in the networked bookmark a suggested presentation offset that indicates an offset in time from the bookmark-created time to the bookmark-presentation time; and the first WTRU transmitting the networked bookmark, including the suggested presentation offset, to an Internet Protocol (IP) Multimedia Subsystem (IMS) network for use by a second WTRU in replicating, at the second WTRU, the presentation of the media program at the first WTRU.

  • Patent number: 9838473
    Abstract: Disclosed herein are methods and systems for integrating peer-to-peer (P2P) networks with content delivery networks (CDNs). In an embodiment, a method for use in a network storage control peer (NSCP) supporting P2P operation includes receiving swarm stats from a tracker; determining, based on the received swarm stats, a P2P rarity associated with a content piece; and responsive to the determined P2P rarity, transmitting an upload request message to an ingestion gateway, wherein the upload request message indicates that the content piece is to be uploaded to a CDN.

  • Patent number: 9661029
    Abstract: A method and apparatus for generating a topology for wireless peer-to-peer (P2P) networks. A network architecture comprises a traffic optimization service including a traffic optimization server and an adaptor to effect bi-directional translation of a request-response protocol of the traffic optimization service and a signaling protocol of a multimedia network. The traffic optimization server stores information related to wireless communication systems comprising user/location id information including cache proxies, media gateways, and network peers of multiple access networks and cost metric information including maximum bit rate, guaranteed bit rate, storage capacity, CPU capabilities, number of clients serving, battery capabilities, reliability of path, and supported video/audio codec.

  • Patent number: 9621537
    Abstract: An application server receives a request for service from a wireless transmit/receive unit (WTRU) associated with a home network that includes a home subscriber server (HSS) and a bootstrapping server function (BSF) coupled via a Zh reference point. The application server authenticates the WTRU at least in part by (i) redirecting the WTRU to an identity provider co-located with a network application function (IDP/NAF) and coupled to the BSF via a Zn reference point and (ii) receiving an assertion from the WTRU that the IDP/NAF has authenticated the WTRU based on user security settings retrieved from the BSF by the IDP/NAF over the Zn reference point. After authenticating the WTRU, the application server (i) retrieves user-specific Sh-reference-point-type data from the HSS via the IDP/NAF over the Zn and Zh reference points and (ii) provides the service to the WTRU based on the retrieved user-specific Sh-reference-point-type data.

  • Patent number: 9560088
    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.

  • Patent number: 9497627
    Abstract: 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.
