摘要： Two methods in an IP Multimedia Subsystem, IMS, network. In the first method, a first function sends a SIP request other than a SIP INVITE towards a destination node (B4). If no response to the SIP request is received (B7), the first function sends a signal addressed to a second function on route to the destination node (B8). If no response to the SIP request or the signal is received (B10), the first function assumes that the second function has failed and determines whether to initiate reselection of a replacement function. If a response to the SIP request or signal is received, the first function assumes that the second function has not failed. In the second method, a first function detects a failure of a second function during an attempt to send a Session Initiation Protocol, SIP, request. The first function then determines whether conditions for reselection of a replacement function are fulfilled (B13), and only if the conditions for reselection are fulfilled, performs a reselection procedure (B14). The two methods may be used together or separately.

摘要： There is provided a method of processing an IMS session originated by a UE after restart of a S-CSCF that was previously assigned to a user of the UE during registration with the IMS, when a further S-CSCF is currently assigned to the user. The method comprises, at a HSS, receiving a request to register a user identity of the user from the previously assigned S-CSCF, determining that the previously assigned S-CSCF is not the same as a S-CSCF currently assigned to the user, determining if IMS restoration procedures are supported for the UE, and, if IMS restoration procedures are not supported for the UE, sending a response to the previously assigned S-CSCF, the response identifying the further S-CSCF currently assigned to the user.
摘要翻译：提供了一种在当向用户当前分配进一步S-CSCF时，在重新启动先前在向IMS注册期间分配给UE的用户的S-CSCF之后处理由UE发起的IMS会话的方法。该方法包括：在HSS处从先前分配的S-CSCF接收注册用户的用户身份的请求，确定先前分配的S-CSCF与当前分配给用户的S-CSCF不相同，确定是否支持UE的IMS恢复过程，并且如果UE不支持IMS恢复过程，则向先前分配的S-CSCF发送响应，该响应标识当前分配给用户的另一S-CSCF。

摘要： The present invention relates to a method and a node for storing subscription-related information as well as a method carried out in a node including a call session control function or applications server function and a corresponding node. There is a need to diminish signaling load in an IMS and/or shorten signaling time, particularly when updating user profiles in respect to service profiles. This is addressed by a method comprising the steps of receiving a request message identifying a user; determining whether the received request message comprises an indication of support of a user type associated with the user, the user type indicating that the user shares a certain user profile with other users; and storing for the user an attribute associated with the user type, which attribute is common for a plurality of users all associated with the same user type, if the received request message comprises the indication of support of the user type.
摘要翻译：本发明涉及用于存储订阅相关信息的方法和节点以及在包括呼叫会话控制功能或应用服务器功能和对应节点的节点中执行的方法。需要减少IMS中的信令负载和/或缩短信令时间，特别是在更新关于服务简档的用户简档时。这通过一种方法来解决，该方法包括以下步骤：接收标识用户的请求消息; 确定所接收的请求消息是否包括与用户相关联的用户类型的支持指示，指示用户与其他用户共享特定用户简档的用户类型; 以及如果所接收的请求消息包括所述用户类型的支持的指示，则为用户存储与所述用户类型相关联的属性，所述属性对于与所述相同用户类型相关联的多个用户是共同的。

摘要： The present invention faces the issue of UE enabled to communicate with an IP Multimedia Subsystem following protocol versions older than Release 9, and provides for an alternative P-CSCF restoration procedure. In this alternative P-CSCF restoration procedure, the UE submits to the IMS network UE capability information indicating that the UE is enabled to receive a list with one or more further available P-CSCF entities and to re-register in the IMS network with one of them; at least one entity of the IMS network stores this UE capability information; upon detecting unavailability of the P-CSCF entity to handle a terminating request towards the UE, the UE capability information is provided towards and access network entity; the access network entity determines based on the received UE capability information that the UE is enabled to receive a list with one or more further available P-CSCF entities, obtains the list with further available P-CSCF entities and submits said list to the UE; and the UE reregisters to a further P-CSCF entity selected from the list.
摘要翻译：本发明面向能够在比版本9更早的协议版本之后与IP多媒体子系统进行通信的UE的问题，并提供替代的P-CSCF恢复过程。在该替代的P-CSCF恢复过程中，UE向IMS网络UE提交表明UE能够使用一个或多个其他可用P-CSCF实体接收列表的能力信息，并且在IMS网络中重新注册一个的; IMS网络的至少一个实体存储该UE能力信息; 在检测到P-CSCF实体处理向UE的终止请求的不可用性时，向接入网实体提供UE能力信息; 所述接入网络实体基于所接收的UE能力信息来确定所述UE是否能够使用一个或多个另外可用的P-CSCF实体接收列表，使用其他可用P-CSCF实体获得所述列表并将所述列表提交给所述UE; 并且UE重新注册到从列表中选择的另外的P-CSCF实体。

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）。
