摘要： A method is provided of performing a handover with SRVCC to a target PS access network of an emergency call to a PSAP from a UE accessing a CS access network. The method includes sending a handover request from the CS access network towards an I MS network to transfer the emergency call. A CS to PS emergency handover command is sent to the UE, including an emergency STN identifying an access transfer control function. The UE sends a SIP INVITE to establish an emergency IMS session over the PS access network. The SIP INVITE includes the emergency STN so that the INVITE is routed to the access transfer control function. The emergency call sent over the CS access network with the emergency I MS session are correlated and the emergency call is switched to the emergency IMS session over the PS access network to complete the handover.

摘要： A subscriber server (154) is described that routes a terminating call in a network (150) that includes a circuit switched (CS) network (104), a packet switched (PS) network (105), and an IP Multimedia Subsystem (IMS) (108). The server (154) receives a request for routing information in relation to the terminating call from a CS node (152) in the CS network (104). A determination is made at server 154 based on whether a UE (115) associated with the terminating call is registered in the IMS (108) and whether the UE (115) has access to the PS network (105). The server (154) instructs the CS node (152) to route (158) the terminating call in the CS network (104) when the UE (115) is not registered in the IMS (108) or when the UE (115) does not have access to the PS network (105). Alternatively, the server (154) instructs the CS node (152) to send the terminating call to the IMS (108) for handling (156) when the UE (115) is registered in the IMS (108) and when the UE (115) has access to the PS network (105). In this way, a terminating call is prevented from being unnecessarily routed or handled by the IMS (108).
摘要翻译：描述了在包括电路交换（CS）网络（104），分组交换（PS）网络（105）和IP多媒体子系统（IMS）的网络（150）中路由终止呼叫的订户服务器（154）（108）。服务器（154）从CS网络（104）中的CS节点（152）接收关于终止呼叫的路由信息的请求。基于在终端呼叫中关联的UE（115）是否登记在IMS（108）中以及UE（115）是否可以访问PS网络（105），确定服务器154。当UE（115）没有在IMS（108）中注册时，或者当UE（115）执行的时候，服务器（154）指示CS节点（152）将终止呼叫路由（158）到CS网络（104）无法访问PS网络（105）。或者，当UE（115）注册到IMS（108）中时，服务器（154）指示CS节点（152）向IMS（108）发送终止呼叫以进行处理（156），并且当UE（115））可访问PS网络（105）。以这种方式，防止终止呼叫被IMS不必要地路由或处理（108）。

摘要： A method is provided of 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. A request for the transfer of the session is received. An indication of a voice codec that is currently being used for the session is obtained from the IMS network. Allocation of resources for the session in the CS access network is initiated, including specifying the voice codec to be used based on the obtained codec indication. Transfer of the session to the CS access is initiated so that the session continues with use of the specified voice codec.

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 hand over 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 and apparatus for handling a call transfer from a circuit switched access network to a packet switched access network. A Mobile Switching Centre Server receives a notification that a call for a terminal requires handover from a circuit switched access network to a packet switched access network. The MSC Server determines whether the terminal is currently registered in an IMS network and/or whether the MSC Server is registered such that it can perform handover from the circuit switched access network to the packet switched access network. If so, then return Single Radio Voice Call Continuity is invoked to perform a handover of the call from the circuit switched access network to the packet switched access network. If not then the MSC Server invokes error handling procedures.

摘要： A method for moving a user equipment (UE), from a circuit-switched (CS), communication network to a preferred packet switched (PS), communication network. The UE is attached via a radio access network (RAN), node to the CS network for executing a CS service. The method comprises the step of providing, by a core network control node of the preferred PS network, a fast-return-preference (FRP), indicator which is associated to the UE, to a core network control node of the CS network. Further the method comprises the steps of forwarding, by the core network control node of the CS network, the FRP indicator to the RAN node and initiating, by the RAN node, a move of the UE to the preferred PS network, based on the FRP indicator, if the UE can be connected to the preferred PS network and the provisioning of the CS service in the CS network is stopped.

摘要： A method of informing a control node (110) in a serving communication network (106) of address information about a session anchor node in the serving communication network (106) is described. The control node (110) is accessible by a terminal (104) via a circuit switched access of the serving communication network (106). The serving communication network (106) of the terminal (104) is different from an internet protocol based home communication network (102) of the terminal (104). The method is executed by a session anchor node (108) in the home communication network (102). The method comprises receiving (120) an update request for the control node (110) being updated of address information about the session anchor node in the serving communication network (106), receiving (120) address information about the session anchor node in the serving communication network (106), and sending (130) the received address information based on the received update request. The latter may enable the control node (110) to route a session of the terminal (104) via the session anchor node in the serving communication network (106).

摘要： The invention related to handling core network entities of a radio core communications network comprising a first network entity and a second network entity. The said second network entity differs from the first network entity in that it is capable of processing inter-working between messages exchanged with said radio core communications network and messages exchanged with an IP multimedia subsystem. In other words, one network entity is capable of performing inter- working while the other one not. The first and/or second network entities are provided (S200) with configuration information indicating a relationship between the two network entities. The invention then foreseen routing (S300) messages relating to calls established between the at least one user terminal attached to the entity non capable of inter-working and a further user terminal attached to said IP multimedia subsystem according to said configuration information.
