摘要： A method (500) for routing a terminating call (102) to a user equipment (104) via a first control node (106) for controlling the call (102), wherein the user equipment (104) is attached to a second control node (108) which is adapted to provide routing information. The method (500) comprises determining (504), by the second control node (108), if the user equipment (104) is attached to the second control node (108) over a third control node (110), wherein the attachment over the third control node (110) indicates that call control shall be performed by a specific service domain (112). Based on the determining (504), the provided routing information is selected (506) by the second control node (108), wherein the routing information indicates to the first control node (106) if the further call establishment to the user equipment (104) is controlled either by the second control node (108) or by the third control node (110). The call is then routed (508), by the first control node (106), according to the selected routing information.

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： The invention relates to techniques for terminating a call to a user in a mobile telecommunication network having a circuit switched CS access and service execution centralized in IP Multimedia Subsystem IMS. It is proposed to send the IMSI number of the user to the IMS during a registering of the user in the IMS, preferably with the SIP REGISTER message. Further when a call terminating request is received in the IMS, a SIP INVITE is generated and the IMSI number is provided to the MSC Server. The MSC server contacts the VLR for the purpose of call termination and in case the user is not found in the VLR, a restoring procedure is performed by contacting a HLR using the IMSI number and by providing the user's data to the VLR. The restoring procedure may be performed by means of the MAP restore procedure.
