摘要： A technique for operating a network node during a Mobile Terminating Roaming Forwarding (MTRF) procedure is described. The MTRF procedure involves a first MSC paging a Mobile Subscriber (MS) and a second MSC where the MS is performing a location update. A method implementation of the technique performed by the first MSC includes receiving an information request message, receiving from the second MSC, a Mobile Subscriber Roaming Number (MSRN) associated with the call to the MS, and sending, in response to the information request message, the MSRN towards a Gateway MSC.

摘要： In a mobile network with a plurality of access networks (210, 220), a control node (110) which is controlling access of a user equipment (300) to that one of the access networks (210, 220) which is currently used by the user equipment (300) determines an access capability of the user equipment (300) in said access network (210, 220), e.g. support of voice communication over packet switched access. The control node (110) provides an indication of the determined access capability to a subscriber database (150) associated with the user equipment (300). The indication may then be retrieved from the subscriber database (150) and be used to control termination of a connection to the user equipment (300).

摘要： Exemplary methods for establishing an emergency call and an emergency call-back for a first User Equipment (UE) communicatively coupled to a visited Internet Protocol Multimedia Subsystem (IMS) network includes establishing an emergency call by the first UE sending an emergency call request to a Proxy Call Session Control Function (P-CSCF) in the visited IMS network. The methods further include providing, from the P-CSCF to a Serving CSCF (S-CSCF) in a home IMS network for the first UE, information comprising an indication that the emergency call has been performed and an equipment identifier of the first UE. The methods further include receiving, in the S-CSCF, an emergency call-back request from an emergency call-center, and using, in the S-CSCF, information comprised in the received emergency call-back and the information provided by the P-CSCF, to route the emergency call-back to the first UE and/or to a second UE.

摘要： A method of selecting a target core network of a communication network for handing over a voice session of a terminal from a packet switched source radio access network (RAN) to a target RAN. The voice session is anchored in an Internet Protocol Multimedia Subsystem, and the selected target core network includes a circuit switched domain which is associated with the target RAN and supports voice session continuity to hand over the voice session from the source RAN to the target RAN. The target RAN is associated with a network identification of the target core network. The method is executed by a node and includes receiving a network identification of at least one target core network associated with at least one target RAN. The target core network is selected based on an indicated support of voice session continuity by the network identification.

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 mechanism is presented for performing a session transfer with Single Radio Voice Call Continuity, SRVCC, from a Packet Switched, PS, access to a Circuit Switched, CS, access of a telecommunications session that has been established over the PS access via an IP Multimedia Subsystem, IMS, network. The method includes receiving a request for the transfer of the session to the CS access. An indication of an already-seized media gateway, MGW, that has been established for use in one or more other sessions over the CS access is obtained from the IMS network. A MGW is selected as a Mobile-Media Gateway, M-MGW, for the session based on the obtained indication. Allocation of resources for the session in the CS access network is initiated, including specifying the MGW to be used as the Mobile-Media Gateway, M-MGW. Transfer of the session to the CS access is then initiated.

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.
