摘要： Techniques for the secure generation of a set of encryption keys to be used for communication between a wireless terminal and an assisting base station in a dual-connectivity scenario. An example method includes generating (810) an assisting security key for the assisting base station, based on an anchor base station key. The generated assisting security key is sent (820) to the assisting base station, for use by the assisting base station in encrypting data traffic sent to the wireless terminal or in generating one or more additional assisting security keys for encrypting data traffic sent to the wireless terminal while the wireless terminal is dually connected to the anchor base station and the assisting base station. The anchor base station key, or a key derived from the anchor base station key, is used (830) for encrypting data sent to the wireless terminal by the anchor base station.

摘要： The present invention relates to a method and an operator network node for enabling a user-defined DRM domain of *SIMs hosted by *SIM-enabled devices. The operator network node is connectable to a *SIM based device and to a content provider node, and comprises means for establishing a secure channel between a *SIM-based device and an operator network node, means for creating a DRM domain defined by at least one user of *SIM-based devices, means for receiving at the operator network node a registration request from the *SIM-based device to register the *SIM of the *SIM-based device into the created user-defined DRM domain, means for registering at the operator network node the *SIM of the *SIM-based device into the registered user-defined DRM domain, and means for making the registered information associated with the user-defined DRM domain available to the content provider. The invention also relates to a further method and the content provider comprising means for accessing in the operator network node registered information associated with a registered user-defined DRM domain comprising *SIMs of a user, and means for establishing a content provider defined DRM domain comprising at least one of the *SIMs of the user-defined DRM domain.

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 authorized, 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。
