摘要： A method and network node for terminating an IP Multimedia Subsystem (IMS)-enabled communication service involving a user terminal, which has been allocated an IP address by an access network used by the terminal to access the communication service. Upon determining that the IP address is no longer allocated to the user by the access network, the node terminates the IMS communication service.

摘要： A method and system for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network is provided. According to an embodiment of the present invention, the media path includes one or more gateway nodes. Each gateway node includes a gating function for gating media packets. Each gating function has an associated controlling function for controlling the gating function. Responsive to a message indicating at an update of the gating at the gating function is required, the gating function arranges for a new gating to be opened while keeping the old gating open. The gating function determines when the media has been switched to the new path. Responsive to the determination, the gating function arranges for the old gating to be closed.

摘要： Methods and apparatuses for updating policy and charging rules relating to early dialogs in session initiation protocol forking in a telecommunications network. A node comprises a receiver (304), configured to receive a plurality of preliminary responses originating from a plurality of terminating end points as part of Session Initiation Protocol, SIP, forking. The node comprises an early dialog controller (314), configured, for each received preliminary response, to determine a unique identifier and to control a transmitting means, which may be a transmitter (302), to transmit a corresponding preliminary message comprising the unique identifier to a further node (400) for use as a Policy and Charging Rules Function, PCRF (200), for creating an early dialog by the further node. The receiver is further configured to receive updated data for at least one of the preliminary responses. The node further comprises an updated dialog controller (316) configured to retrieve the unique identifier corresponding to the at least one preliminary response and control the transmitter to transmit an updating message based on the updated data and comprising the retrieved unique identifier to the further node for updating the corresponding early dialog.

摘要： A method and apparatus for establishing a communication session in an IMS Centralized Services communication network. A Service Centralization and Continuity Application Server (SCC AS) receives a request from an originating device to establish a session with a target device. The request includes a plurality of codec identifiers that could be used by the originating device. The SCC AS sends a second request to establish the session to the target device. The SCC AS subsequently receives, from an intermediate node between the SCC AS and the target device, an invite message. The invite message includes an indication that a codec identifier has been selected from the plurality of codec identifiers. The SCC AS then sends a message to the intermediate node instructing the intermediate node to establish the session.

摘要： A method of synchronising streaming media between a plurality of UEs connected to a communications network, wherein the UEs are involved in a SIP-enabled voice session over said communications network. A timestamp is provided to each of the UEs. Each of the UEs then sends a request for streamed media to an IPTV service, receives streamed media from the IPTV service, and commences playout of the streamed media in dependence upon the timestamp.

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 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 key. 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 in their respective leg to said intermediary.
