摘要： A method of informing a control node in a serving communication network of address information about a session anchor node in the serving communication network is described. The control node is accessible by a terminal via a circuit switched access of the serving communication network. The serving communication network of the terminal is different from an internet protocol based home communication network of the terminal. The method is executed by a session anchor node in the home communication network. The method includes receiving an update request for the control node being updated of address information about the session anchor node in the serving communication network, receiving address information about the session anchor node in the serving communication network, and sending the received address information based on the received update request.

摘要： A subscriber server routes a terminating call in a network that includes a circuit switched (CS) network, a packet switched (PS) network, and an IP Multimedia Subsystem (IMS). The server receives a request for routing information in relation to the terminating call from a CS node in the CS network. A determination is made at server based on whether a UE associated with the terminating call is registered in the IMS and the UE has access to the PS network. The server instructs the CS node to route the terminating call in the CS network when the UE is not registered in the IMS or when the UE does not have access to the PS network. The server instructs the CS node to send the terminating call to the IMS for handling when the UE is registered in the IMS and when the UE has access to the PS network.

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.

摘要： A method is provided of handing over a priority call with Single Radio Voice Call Continuity, SRVCC. The priority call is handed over 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 thereby establishing a priority IMS session. The priority call has a specified CS priority level. The method includes sending a handover request from the CS access network towards the PS access network and the IMS network to transfer the priority call. A PS priority level for the session in the PS network is determined based on the specified CS priority level. Bearer resources for the IMS session are allocated. The bearer resources are based, at least in part, on the PS priority level. The call is transferred to the IMS session over the PS access network.

摘要： A method is provided of performing a handover with SRVCC to a target PS access network of an emergency call to a PSAP from a UE accessing a CS access network. The method includes sending a handover request from the CS access network towards an IMS network to transfer the emergency call. A CS to PS emergency handover command is sent to the UE, including an emergency STN identifying an access transfer control function. The UE sends a SIP INVITE to establish an emergency IMS session over the PS access network. The SIP INVITE includes the emergency STN so that the INVITE is routed to the access transfer control function. The emergency call sent over the CS access network with the emergency IMS session are correlated and the emergency call is switched to the emergency IMS session over the PS access network to complete the handover.

摘要： A method and apparatus for enabling delivery of a message in a communication system comprising an IMS domain and a circuit switched domain. Upon receiving a registration message in the IMS domain from a user equipment operated by a user, wherein the message comprises an Equipment Identifier valid for the user equipment and an IMPI valid for the user, the Equipment Identifier and the IMPI are extracted from the received message. Then a creation or an update of a mapping of the Equipment Identifier to the IMPI and a C-MSISDN is initiated. Upon receiving a message, relating to the user, which is to be communicate between the IMS and circuit switched domains in the communication system, a use of the mapping for translating between the Equipment Identifier, IMPI and the C-MSISDN is initiated.

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.
