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.
摘要翻译：通过在服务呼叫/状态控制功能（S-CSCF）处接收会话发起协议（SIP）REGISTER消息，识别始发用户的SIP REGISTER消息，以始发方式接收来提供用于IPTV服务的启用IMS的控制信道用户从S-CSCF收到指示发起用户已被授权的响应，并从S-CSCF发送SIP INVITE消息，以建立与选定的IPTV应用服务器（AS）的开放信道连接。然后，该开放通道连接可以用于控制消息的传输，例如在STB和IPTV应用服务器之间的开始播放，开始记录，停止播放等，以及用于传送个性化内容，诸如作为广告，投票回复，个性化投票触发器和有针对性的交互式活动。通过与IPTV AS保持开放的控制信道，这大大减少了不同应用的建立延迟时间。

摘要： A method of establishing keys for at least partially securing media plane data exchanged between first and second end users via respective first and second media plane network nodes. The method comprises sending session set-up signalling from said first end point towards said second end point, said session set-up signalling including a session key generated by said first end point. The set-up signalling is intercepted at a first signalling plane network node and a determination made as to whether or not a signalling plane key has already been established for securing the signalling plane between said first end point and said first signalling plane network node. If a signalling plane key has already been established, then a media plane key is derived from that signalling plane key, and the media plane key sent to said first media plane network node for securing the media plane between said first end user and said first media plane network node. If a signalling plane key has not already been established, then an alternative media plane key is derived from said session key and sent to said first media plane network node for securing the media plane between said first end user and said first media plane network node.

摘要： A method and arrangement is disclosed for managing session keys for secure communication between a first and at least a second user device in a communications network. The method is characterized being independent of what type of credential each user device implements for security operations. A first user receives from a first key management server keying information and a voucher and generates a first session key. The voucher is forwarded to at least a responding user device that, with support from a second key management server communicating with the first key management server, resolves the voucher and determines a second session keys. First and second session keys are, thereafter, used for secure communication. In one embodiment the communication traverses an intermediary whereby first and second session keys protect communication with respective leg to intermediary.

摘要： A method and apparatus for sending a first secured media stream having a payload via an intermediate node. The intermediate node receives from a sender the first secured media stream. An end-to-end context identifier and a hop-by-hop context identifier are determined for the first secured media stream, where the hop-by-hop context identifier relates to the intermediate node and the end-to-end identifier relates to the sender. A second secured media stream is generated, which includes at least the payload of the first secured media stream and the context identifiers to identify the first secured media stream. The second secured media stream is sent to a receiving node, and the context identifiers are also sent to the receiving node. The context identifiers are usable by the receiving node to recover the first secured media stream.

摘要： A method and apparatus for sending protected media data from a data source node to a client node via an intermediate node. The data source node establishes a first hop- by-hop key to be shared with the intermediate node and an end-to-end key to be shared with the client node. A single security protocol instance is configured and used to transform data from a media stream into transformed data using the keys. The transformed data is then sent to the intermediate node. The intermediate node uses the first hop-by-hop key to apply a security processing to the transformed data, and establishes a second hop-by-hop key with the client node. A second transformation is performed on the transformed data using the second hop-by-hop key to produce further transformed media data, which is then sent to the client node. At the client node a single security protocol instance is configured with the second hop-by-hop key and the end-to-end key, which are used to apply further security processing to the transformed media data.

摘要： A method and arrangement in a multimedia gateway (300) connected to a multimedia service network (304), for providing access to multimedia services for communication devices (302) connected to a private network. In the multimedia gateway, a communication unit (308) receives a request from a device in the private network for a public identity associated with the multimedia gateway. An identity manager (310) then selects and allocates an associated public identity from a pool (314) of public identities associated with the multimedia gateway which have been predefined as valid in the multimedia service network. The communication unit then registers the device by activating the allocated associated public identity in the multimedia service network. Thereby, the multimedia gateway can establish a multimedia session on behalf of the device, using the allocated associated public identity.
