摘要： A method is provided of performing a handover with Single Radio Voice Call Continuity, SRVCC, of a telecommunications session from a User Equipment, UE accessing an IP Multimedia Subsystem, IMS, network via a Circuit Switched, CS, access network to a target Packet Switched, PS, access network. The method includes receiving a handover request from the CS access network to transfer the session and determining that the telecommunications session comprises data media in addition to, or without, any audio media. The ability to perform the handover with SRVCC for the data media is determined. Bearer resources for the session when handed over to the PS access network are allocated, including a data media bearer and, if there is any audio media in the session an audio media bearer. The session is transferred from the CS to the target PS access network.

摘要： A method is provided for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network. 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. A message is received (S5) at a gating function from its associated controlling function indicating that an update of the gating at the gating function is required. The gating function arranges (S6) for a new gating, appropriate for the new or updated media path, to be opened while keeping the old gating, appropriate for the old or previous or existing media path, open (S8). The gating function determines (S7) when the media has been switched, or at least is likely to have been switched, to the new path. When it is so determined, the gating function arranges for the old gating to be closed (S9).

摘要： A system, method, and nodes for managing shared security keys between a User Equipment, UE, an authentication node such as an SCF/NAF, and a service node such as a BM-SC or AS. The SCF/NAF allocates to each BM-SC, a different SCF/NAF identifier such as a fully qualified domain name, FQDN, from the FQDN space the SCF/NAF administers. The SCF/NAF then locally associates these allocated FQDNs with the connected BM-SCs and with different services. The network sends the correct FQDN to the UE in a service description for a desired service, and the UE is able to derive a security key using the FQDN. When the UE requests the desired service, the SCF/NAF is able to associate the service identifier with the correct FQDN and an associated BM-SC. The SCF/NAF uses the FQDN to obtain the security key from a bootstrapping server and sends it to the associated BM-SC.As a result, the UE and the associated BM-SC share a specific security key.

摘要： The invention relates to a method of changing allocation of Serving-Call Session Control Functions (S-CSCFs) to a user of an IMS network. The user is being provided with services via a first S-CSCF allocated to the user. The method includes implementing a re-allocation instruction at the first S-CSCF. The reallocation instruction includes criteria for de-allocation of the user from the first S-CSCF. The S-CSCF determines if the criteria are met; and if the criteria are met, de-allocates the user.

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 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 and apparatus for maintaining service continuity for User Equipment accessing an IP Multimedia Subsystem communication network. A routing identifier is established that identifies a Service Centralization and Continuity Application Server allocated to the User Equipment. The routing identifier is sent to the User Equipment. In the event of disruption to the service between the User Equipment and the Service Centralization and Continuity Application Server, a handover message is sent from the User Equipment via a Circuit Switched access network. The handover message includes the routing identifier, and is then forwarded to the identified Service Centralization and Continuity Application Server. This allows the same Service Centralization and Continuity Application Server to be used after the handover as was used before the handover, thereby providing service continuity.
