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： An IMS system includes an IMS initiator user entity. The system includes an IMS responder user entity that is called by the initiator user entity. The system includes a calling side S-CSCF in communication with the caller entity which receives an INVITE having a first protection offer and parameters for key establishment from the caller entity, removes the first protection offer from the INVITE and forwards the INVITE without the first protection offer. The system includes a receiving end S-CSCF in communication with the responder user entity and the calling side S-CSCF which receives the INVITE without the first protection offer and checks that the responder user entity supports the protection, inserts a second protection offer into the INVITE and forwards the INVITE to the responder user entity, wherein the responder user entity accepts the INVITE including the second protection offer and answers with an acknowledgment having a first protection accept. A method for supporting a call by a telecommunications node.

摘要： A system for generation of processed data for use in third party relationship monitoring is described. The system includes a communications system providing services to subscribing users. The communications system includes a rules database for storing rules, a data mining agent for mining and storing data relating to subscribing users, a content generator for generating protected user-related data from the mined data and communicating said user-related data over an interface, and a rights object generator for generating a usage rights object in response to the rules stored in the rules database and communicating said usage rights object over the interface. A tamper proof processing arrangement is connected to the interface. The tamper proof processing arrangement receives the user-related data and usage rights object from the communications system and processes the user-related data under control of the usage rights object. A signal output generator generates an output signal representative of processed data received from the processing arrangement.

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 means by which a list of service options may be used as capability configuration parameters to specify a card application toolkit call setup command, such as from R-UIM applications, is provided. For example, when the R-UIM application sends a call setup command to a mobile communication station, the R-UIM application may also send a list of service options that may be used by the mobile communication station to negotiate with the network. During the service negotiation process of setting up the call, the mobile communication station will only use or accept a service option that is in the service option list.
