    摘要: An IMS-enabled control channel for an IPTV service is provided by receiving at a Serving Call/State Control Function (S-CSCF) a Session Initiation Protocol (SIP) REGISTER message, the SIP REGISTER message identifying the originating user, receiving at the originating user a response from the S-CSCF indicating that the originating user has been authorised, and sending a SIP INVITE message from the S-CSCF to establish an open channel connection with a selected IPTV Application Server (AS). This open channel connection can then be used for the transmission of control messages, such as for starting play, starting recording, stopping play, etc., between the STB and the IPTV applications server, as well as for the delivery of personalized content, such as advertisements, voting responses, personalized voting triggers and targeted interactive events. By maintaining an open control channel with the IPTV AS, this offers a substantial reduction in the setup delay times for different applications.

    摘要: Disclosed is a DRM device and method for providing secure linking to a user identity. A first request is sent to a subscriber identity module. A message is received from the subscriber identity module via a secure authenticated channel. The message comprises at least a a master key identifier, a random number, and a derived key. In response to the message, a second request is sent to a DRM server. The second request comprises at least a master key identifier, the device identifier, and a random number. Also disclosed is a DRM server and method for providing secure linking to a user identity. A first request is received from a DRM device. The first request comprises at least master key identifier, a device identifier, and a random number. The DRM device is authenticated. A second request for an application specific key is sent to a trusted key management server. The second request comprises at least a master key identifier. At least a key is received from the trusted key management server. A derived key is determined from the key received from the trusted key management server based at least on the device identifier and the random number. A challenge/response scheme is used to determine whether the derived key of the DRM server matches a derived key of the DRM device.

    摘要: Method and apparatus in a router (200) of an IP network, for providing a relevant and expected service level for a first subscriber (A) in a peer-to-peer session with a second subscriber (B). When a session setup message (PATH) sent from the first subscriber is received (2:2) at the router, a required service level is detected from a service level indicator in the received message, and a service level definition of an operator of the first subscriber is obtained (2:3) for interpreting the service level indicator. Communication resources required for data transmission during the session are determined (2:4) according to the detected service level as interpreted by the service level definition. The determined communication resources are then booked (2:4) in the router, and the session setup message is forwarded (2:7) to a next hop node in the transmission path towards the second subscriber.

    摘要: The present invention relates to methods and arrangements for providing caller information to a SIP enabled client (320), e.g. an IPTV client, in a communication network (10). The SIP enabled client (320) is connected to a SIP communication client (310), e.g. a VoIP client, in a home network (300). When another SIP communication client (100) in the communication network (10) calls the VoIP client (310) the call is forwarded to the VoIP client and forked to a caller ID application server (200). As the IPTV client has registered for a subscription to caller information on communication destined to the VoIP client in the home network, it receives caller information of the SIP communication client (100) from the caller ID application server (200) if the VoIP client has enabled the caller information functionality.

    摘要: Mobile communication network (301), mobility node (322) and method for selecting, as a user terminal (304) moves in the mobile communication network (301) from a first node (306) to a second node (311), a cache (308 or 312) that stores a desired content and is closest to the user terminal (304). The method includes receiving a request from the user terminal (304) for a segment of the desired content; querying a mobility functionality (300) run by the mobile communication network (301) about an internet protocol, IP, address of a cache that stores the segment of the desired content; based on a location at the first node (306) or the second node (311) of the user terminal that sent the request, determining the cache (308 or 312) that stores the segment of the desired content and has a location closest to the user terminal (304); and providing the user terminal (304) with an answer that includes the IP address of the closest cache that stores the segment of the desired content.

    摘要: A method of managing a unicast-based media session is disclosed. A user terminal having access to channel identifiers of media channels available at a media server compiles a SIP-based channel request comprising a channel identifier of one of the available media channels and a port identifier of at least one media input port of the terminal. This message is sent to a network node for initiating delivery of media data of selected media channel to the announced media input port. The SIP-based data signaling also allows switching between unicast-based media channels and switching between unicast-bast and multicast/broadcast-based media channels during the ongoing media session.

    摘要: A flexible and context-aware delivery scheme for uniform resource locators builds on a generic representation that can be used for whichever binary content is to be delivered to a client. It can also be applied to improve the network operations of a network operator, the user's perceived quality of experience, and the costs of a content provider that does not need to encode and support different codecs and transport mechanisms.
