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 emergency call access transfer function, EATF, node (138a) is described for use when hand over of a user equipment, UE, (108) from a first to a second access network (104 to 106) to is performed during an emergency call session, ECS. The EATF node (138a) receives a request for transferring the ECS from the first access network (104) to the second access network (106). The EATF node (138a) transfers the ECS of the UE (108) from the first access network (104) to the second access network (106) when the ECS is known to the EATF node (138a). The EATF node (138a) will select a second EATF node (138b) from a set of one or more EATF nodes when the ECS is unknown or not anchored with the EATF node (138a), and forwards the request for transferring the ECS to the second EATF node (138b). The EATF node (138a) may be in a first network region and the second EATF node (138b) may be in the first or a second network region. In this way, an efficient hand over or transfer mechanism for ECSs can be performed when distributing ECS network load over multiple EATF nodes (138a, 138b) within the same or different network regions, and without requiring other network nodes to maintain knowledge of the EATF nodes (138a, 138b) anchoring the ECS of UE (108).
摘要翻译：描述紧急呼叫接入传递功能EATF节点（138a），用于当用户设备UE（108）从第一到第二接入网络（104至106）切换时在紧急呼叫期间执行会议，ECS。 EATF节点（138a）接收从第一接入网络（104）向第二接入网络（106）传送ECS的请求。当ECAT对于EATF节点（138a）是已知的时，EATF节点（138a）将UE（108）的ECS从第一接入网络（104）传送到第二接入网络（106）。当ECS未知或不与EATF节点（138a）一起固定时，EATF节点（138a）将从一个或多个EATF节点的集合中选择第二EATF节点（138b），并将用于将ECS传送到第二EATF节点（138b）。 EATF节点（138a）可以在第一网络区域中，并且第二EATF节点（138b）可以在第一或第二网络区域中。以这种方式，当在相同或不同网络区域内的多个EATF节点（138a，138b）上分发ECS网络负载时，可以执行用于ECS的有效的切换或传送机制，并且不需要其他网络节点来维护EATF的知识锚定UE（EC）的节点（138a，138b）。

摘要： A method performs a Single Radio Voice Call Continuity, SRVCC, Packet Switched, PS, to Circuit Switched, CS, handover of an emergency call that is routed over an IP Multimedia Subsystem, IMS, network. The emergency call is first transferred from an access in a first region served by a first Mobility Management Entity, MME, to a second region served by a second MME. The method includes sending a first handover request from the first MME to the second MME to transfer the call to the second region. The first handover request includes an Emergency Session Transfer Number for SRVCC, E-STN-SR, identifying an Emergency Access Transfer Function, EATF, in the first region. A second handover request for handover to a CS access is sent to a target Mobile Switching Centre, MSC, and includes the E-STN-SR. The emergency call is handed over to the CS access using the E-STN-SR to route the call via the EATF in the first region.

摘要： A method is provided of performing a handover with Single Radio Voice Call Continuity, SRVCC, of a telecommunications session 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. The method includes receiving a handover request from the CS access network to transfer the session and determining that the telecommunications session comprises data media in addition to, or without, any audio media. The ability to perform the handover with SRVCC for the data media is determined. Bearer resources for the session when handed over to the PS access network are allocated, including a data media bearer and, if there is any audio media in the session an audio media bearer. The session is transferred from the CS to the target PS access network.

摘要： A method is provided for updating or handling the update of a media path between a first user terminal and a second user terminal in a telecommunications network. The media path includes one or more gateway nodes. Each gateway node includes a gating function for gating media packets. Each gating function has an associated controlling function for controlling the gating function. A message is received (S5) at a gating function from its associated controlling function indicating that an update of the gating at the gating function is required. The gating function arranges (S6) for a new gating, appropriate for the new or updated media path, to be opened while keeping the old gating, appropriate for the old or previous or existing media path, open (S8). The gating function determines (S7) when the media has been switched, or at least is likely to have been switched, to the new path. When it is so determined, the gating function arranges for the old gating to be closed (S9).

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 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.
