摘要： A communication network comprises a packet switched domain associated with a packet switched capable radio access network and supports an Internet Protocol Multimedia Subsystem voice session via the packet switched capable radio access network. The terminal supports an Internet Protocol Multimedia Subsystem voice session via the packet switched capable radio access network and an Internet Protocol Multimedia Subsystem emergency voice session via the packet switched capable radio access network. A method is executed by a control node of the packet switched domain and comprises sending instruction information to the terminal. The instruction information instructs the terminal to execute an Internet Protocol Multimedia Subsystem voice session via the packet switched capable radio access network without regard to whether the communication network has indicated support of an emergency session related data transmission via the packet switched capable radio access network and the packet switched domain.

摘要： A method of and equipment for subscriber mobility registration update in a Home Location Register, HLR, (14) of a Global System for Mobile communications, GSM, or a Universal Mobile Telecommunications System, UMTS, mobile telecommunications network. The HLR (14) receives and stores subscriber mobility registration information from at least one Mobile Switching Centre, MSC, (11, 12) of the telecommunications network. The HLR (14) instructs (21; 61) an MSC (11, 12) to forward intermediate subscriber mobility registration update messages (23; 31; 41; 51; 63) to the HLR (14) for specific mobility events of a subscriber (1). The HLR (14) receives an intermediate subscriber mobility registration update message (23; 31; 41; 51; 63) of the MSC (11, 12) when such a specific mobility event occurs, and the subscriber mobility registration in the HLR (14) is updated on the basis of a received intermediate subscriber mobility registration update message (23; 31; 41; 51; 63) by the HLR (14). The method is especially applicable for IP Multimedia Subsystem Centralised Services, ICS.

摘要： The basic concept of the invention is to expand the capabilities of the MSC Server enhanced for SR-VCC and of the SCC AS to support a "session transfer revocation" procedure. To allow for such procedure it is envisaged that a MSC-Server enhanced for SR-VCC being involved in a Handover procedure for a call from a source RAN, e.g. E-UTRAN/UTRAN HSPA, to a target RAN, e.g. GERAN/UTRAN CS, sends an indication that a session transfer for said call should be performed towards the target RAN. Once the MSC-Server receives from a mobility management entity, such as MME or SGSN, of the source RAN an indication that a relocation request having initiated the session transfer indication is canceled, the MSC-Server may send an indication that the session transfer should be cancelled towards the SCC AS in the IMS which has performed the session transfer.
摘要翻译：本发明的基本概念是扩展为SR-VCC和SCC AS增强的MSC服务器的能力以支持“会话转移撤销”过程。为了允许这样的过程，设想为SR-VCC增强的MSC-服务器参与来自源RAN的呼叫的切换过程，例如， E-UTRAN / UTRAN HSPA到目标RAN，例如， GERAN / UTRAN CS发送应该向目标RAN执行所述呼叫的会话转移的指示。一旦MSC-服务器从源RAN的移动性管理实体（例如MME或SGSN）接收到已经发起已经发起会话转移指示的重定位请求的指示被取消，则MSC-服务器可以发送关于会话转移应该在已经执行会话转移的IMS中向SCC AS取消。

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 comprises 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： A method is provided of handing over a priority call with Single Radio Voice Call Continuity, SRVCC. The priority call is handed over from a User Equipment, UE, accessing an IP Multimedia Subsystem, IMS, network via a Circuit Switched, CS, access network to a target Packet Switched, PS, access network thereby establishing a priority IMS session. The priority call has a specified CS priority level. The method includes sending a handover request from the CS access network towards the PS access network and the IMS network to transfer the priority call. A PS priority level for the session in the PS network is determined based on the specified CS priority level. Bearer resources for the IMS session are allocated. The bearer resources are based, at least in part, on the PS priority level. The call is transferred to the IMS session over the PS access network.

摘要： A method of selecting a target core network (110) of a communication network (100) for handing over a voice session of a terminal (118) from a packet switched source radio access network (104) of the communication network (100) to a target radio access network of the communication network (100) is described. The voice session is anchored in an Internet Protocol Multimedia Subsystem of the communication network (100), and the selected target core network (110) comprises a circuit switched domain which is associated with the target radio access network and supports voice session continuity allowing to hand over the voice session from the packet switched source radio access network (104) to the target radio access network. The target radio access network is associated with a network identification of the target core network (110). The method is executed by a node (112) of the source radio access network (104). The method comprises receiving (126) a network identification of at least one target core network (110) associated with at least one target radio access network. The network identification indicates support for voice session continuity. The method comprises selecting (138) the target core network (110) based on the indicated support of voice session continuity indicated by the received network identification. Thus, a successful handover of the terminal (118) from the packet switched source radio access network (104) to the target radio access network employing voice session continuity may be accomplished.
