摘要： A technique for handling mobile terminating connection attempts for a mobile terminal for which a change of an association from a first routing node to a second routing node is accompanied by a Circuit Switched (CS) fallback is described. A method implementation of this technique comprises the following steps carried out by the first routing node: receiving a first mobile terminating connection attempt to the mobile terminal, in response to receipt of the first mobile terminating connection attempt, determining that the mobile terminal cannot be reached by the first routing node, determining an identity of the second routing node, and transmitting, to the second routing node, a second mobile terminating connection attempt for a CS connection to the mobile terminal.

摘要： A method and application server for supporting a communication established between a first mobile terminal towards a telecommunications network that includes first and second radio access networks. When a session setup is initiated with respect to the first mobile terminal, the application server receives a session identifier. The application server enters the identifier into an identifier list comprising one or more identifiers for identifying sessions with respect to the first mobile terminal. If the application server receives an indication of a session transfer from the first radio access network to the second radio access network, the application server provides the identifier list to the second radio access network in response to the indication.

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 for routing a terminating call to a user equipment via a first control node for controlling the call, wherein the user equipment is attached to a second control node which is adapted to provide routing information. The method comprises determining, by the second control node, if the user equipment is attached to the second control node over a third control node, wherein the attachment over the third control node indicates that call control shall be performed by a specific service domain. Based on the determining, the provided routing information is selected by the second control node, wherein the routing information indicates to the first control node if the further call establishment to the user equipment is controlled either by the second control node or by the third control node. The call is then routed, by the first control node, according to the selected routing information.
