摘要： A solution is presented that includes a method of performing a Single Radio Voice Call Continuity, SRVCC, handover of a telecommunications call established by a User Equipment, UE accessing a serving network using a Packet Switched, PS, access. The serving network includes a serving IMS network and the call is a UE-undetected emergency call anchored in the serving IMS network. The method includes receiving an indication from the serving network that the established call is a UE-undetected emergency call anchored in the serving IMS network. A SRVCC handover request to hand over the call from the PS access to a Circuit Switched, CS, access is received. Handover of the call is initiated so that an Emergency Session Transfer Number-Single Radio, E-STN-SR, is used and the call continues to be routed through the IMS network in which it is anchored.

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 subscriber database maintains a data record related to a user equipment. The subscriber database receives an indication from a control node which is responsible for controlling a plurality of packet switched network accesses, The indication indicates whether voice communication with the user equipment over circuit switched access is supported or unsupported homogeneously for all the network accesses controlled by the control node. The subscriber database stores the indication in the data record. If the subscriber database receives a request from a termination control node which is responsible for controlling termination of a voice session with the user equipment, it processes the request depending on the stored indication. In some cases, if the indication indicates that voice communication with the user equipment over circuit switched access is unsupported homogeneously, the subscriber database may reject the request without further interaction with other nodes.

摘要： A method and apparatus for transferring a session from a packet switched access network to a circuit switched access network. A Mobility Management Entity receives a service type indicator from a gateway node. The service type indicator indicates a type of service for the session, and is associated with bearers used for the session. The Mobility Management Entity subsequently receives, from an eNodeB, an indication that the session is to be transferred from the packet switched network to the circuit switched access network. The Mobility Management Entity determines the bearers associated with the session using the service type indicator, and initiates transfer of the session using those bearers. This ensures that the correct bearers are transferred regardless of whether or not identifiers such as QCI values have been ascribed to other types of service.

摘要： A method of routing a session from a calling party in a serving communication network of the calling party to a called party is described. The serving communication network of the calling party is distinct from a home communication network of the calling party. The method is executed by a session routing node in the serving communication network of the calling party. In order to optimize a session routing path of signaling data of the session, the method comprises receiving from the home communication network of the calling party a session routing request requesting routing the signaling data of the session to the called party via the serving communication network of the calling party, and routing the signaling data of the session to the called party via the serving communication network of the calling party based on the received session routing request.
