摘要： A technique for coordinating the registration of a terminal (UE) in circuit-switched (CS) and packet-switched (PS) domains of a multi-operator core network (MOCN) with multiple core networks (CN) is described. According to a method approach, a notification message indicating the necessity of coordinated CS and PS registrations for a terminal (UE) is received from a first core network (CN). In a next step, and based on a global permanent identity (IMSI) associated with the terminal (UE), a second core network (CN) responsible for CS and PS registrations is determined. A registration message for coordinated CS and PS registrations is then sent to the second core network (CN) that has been determined based on the global permanent identity (IMSI).

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 of providing in a packet switched telecommunications network, for a communications session involving a user of said packet switched telecommunications network a value added service associated with a circuit switched telecommunication network. The method comprises the steps of establishing a first signaling data stream of a first basic call state model of a packet switched dedicated protocol type between the packet switched telecommunications network and a service interface adapter unit, and establishing a second signaling data stream of a second basic call state model of a circuit switched dedicated protocol type between the service interface adapter unit and the circuit switched telecommunications network, based on information from the first signaling data stream, for providing the value added service from the circuit switched telecommunications network. The information is augmented with further information for establishing the second signaling data stream, and for exchanging data between the first and second signaling data stream for providing the value added service to the user through the packet switched telecommunications network.

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.
