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： An IMS system includes an IMS initiator user entity. The system includes an IMS responder user entity that is called by the initiator user entity. The system includes a calling side S-CSCF in communication with the caller entity which receives an INVITE having a first protection offer and parameters for key establishment from the caller entity, removes the first protection offer from the INVITE and forwards the INVITE without the first protection offer. The system includes a receiving end S-CSCF in communication with the responder user entity and the calling side S-CSCF which receives the INVITE without the first protection offer and checks that the responder user entity supports the protection, inserts a second protection offer into the INVITE and forwards the INVITE to the responder user entity, wherein the responder user entity accepts the INVITE including the second protection offer and answers with an acknowledgment having a first protection accept.

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 sending protected data from a sender unit to a receiver unit via an intermediate unit. The intermediate unit stores information associated with a certificate belonging to the receiver unit, and information associated with a certificate belonging to the intermediate unit, which has previously been signed by the receiver unit. The intermediate unit receives a request from the sender unit to send protected data to the receiver unit, and so it sends a response to the sender unit. The response includes the information associated with the certificate belonging to the receiver unit, which allows the sender unit to verify that the intermediate unit is authorised to receive data on behalf of the receiver unit. The intermediate unit then receives data from the sender unit that is protected using the information associated with the certificate belonging to the receiver unit for subsequent forwarding to the receiver unit. Having the receiver unit sign the intermediate unit's certificate allows the exchange of credentials to allow a sender unit to send protected data to a receiver unit via an intermediate unit.

摘要： In a mobile network with a plurality of access networks (210, 220), a control node (110) which is controlling access of a user equipment (300) to that one of the access networks (210, 220) which is currently used by the user equipment (300) determines an access capability of the user equipment (300) in said access network (210, 220), e.g. support of voice communication over packet switched access. The control node (110) provides an indication of the determined access capability to a subscriber database (150) associated with the user equipment (300). The indication may then be retrieved from the subscriber database (150) and be used to control termination of a connection to the user equipment (300).

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.
