摘要： A method is provided for facilitating recovery from the failure of a Serving Call Session Control Function (S-CSCF) within an IP Multimedia Subsystem (IMS) network. The method comprises receiving at a Proxy Call Session Control Function (P-CSCF) a SIP request sent by a User Equipment (UE) possessing an identity previously registered with the IMS network and for which a given S-CSCF was selected. At said P-CSCF it is determined if said given S-CSCF has failed or is otherwise unreachable. If the S-CSCF has failed or is otherwise unreachable, a reregistration message is sent from the P-CSCF to said UE, receipt of said reregistration message at the UE forcing the UE to perform an IMS registration procedure with the IMS network.

摘要： A method, by a first node (111), for handling provision of an IMS service. A communications network (10) comprises a first slice handling a first IMS service, and a 5second slice handling a second IMS service. The first node (111) obtains (202), from a second node (112) at least one of a first and a second indication. The first indication is of a first routing service instance for a third node (113) handling the first service in the first slice. The second indication is of a second routing service instance for a fourth node (114) handling the second service in the second slice. The first node (111) then routes 10(204) a request, to one of the nodes. With the proviso that the request is for the first service, the routing (204) is based on the first indication. With the proviso that the request is for the second service, the routing (204) is based on the second indication.

摘要： A method of evaluating Initial Filter Criteria at a terminating Call Session Control Function in an IP Multimedia Subsystem network. A Session Initiation Protocol comprising a destination Uniform Resource Identifier is received. As a result of applying an Initial Filter Criterion to the message, the message is sent to an Application Server evaluation of further Initial Filter Criteria is suspended. The returned message is received from the Application Server, and a determination is made of whether the Uniform Resource Identifier has been changed by the Application Server. If the Uniform Resource Identifier has been changed by the Application Server, then a determination of whether to resume evaluation of Initial Filter Criteria is made, and if the Uniform Resource Identifier has not been changed by the Application Server, then resuming evaluation of Initial Filter Criteria.

摘要： A method is provided of registering a mobile node (4), such as a User Equipment (UE), 5 of a telecommunications network, such as a Universal Mobile Telecommunications System (UMTS), to a subsystem of the network, such as an IP Multimedia Subsystem (IMS). The network has at least one node (13-1, 13-2), such as a Policy and Charging Rules Function (PCRF), for maintaining or having access to policy and charging rules for users of the network. The network also has at least one node (10), such as a 10 Gateway GPRS Support Node (GGSN), for enforcement of the policy and charging rules to traffic flows. A registration request message, such as a Session Initiation Protocol (SIP) REGISTER message, is received from the mobile node (4) at a proxy node (12), such as a Proxy Call Session Control Function (P-CSCF), of the network. In response, a candidate policy and charging rules node (13-2) is selected for the mobile 15 node (4), and it is determined whether the candidate policy and charging rules node (13- 2) has already been selected by a policy and charging rules enforcement node (10) to serve the mobile node (4). Subsequent steps of the registration procedure are performed in dependence on the determination.

摘要： Embodiments herein relate to a method performed by an IMS node (15) for handling data of a UE (10), in a communication network (1), wherein the communication network (1) comprises partitioned sets of functionalities of one or more core networks wherein each set of functionalities belongs to a network slice. The IMS node (15) receives, from the UE (10), a message for registering the UE (10) to the IMS node (15), wherein the message comprises a slice indication indicating a network slice identity and a UE indication identifying the UE (10). The IMS node (15) stores a registration of the UE (10) in the IMS node (15), in addition to a previously stored registration of the UE (10), with the proviso that the indicated network slice identity differs from a previous network slice identity of the previously stored registration of the UE (10) and thereby allowing parallel active communications using the registration and the previously stored registration.

摘要： A method is provided for facilitating recovery from the failure of a P-CSCF (13) within an IP multimedia Subsystem network. A gateway (11), such as a GGSN, monitors signals arriving at the gateway from the P-CSCF and provides an indication if the monitored signals become unacceptable, for example because of an interruption in the signals. The gateway (11) responds by signalling the unavailability of the P-CSCF (13) to user equipment (10), which was associated with the P-CSCF during a previous registration with the IMS network. In response, for example, the user equipment affected by the failure may request re-registration with the IMS network using a different available P-CSCF.

摘要： Method and apparatuses for collecting user activity information in a telecommunications system. A first telecommunications node (120) handling signaling of the terminal of a user sends a message (516) notifying a registration event (515) of the user to a second node (130) handling registration information of said user. The message comprises an information element (ACT) indicating whether the user has been involved in a service provided during a registration period comprised between a previous registration event (501) of said user and said notified registration event. At reception of the message, the second node updates registration information (430) and activity information (440) of the user. By including service usage information in registration notification messages, the operator of the telecommunications system can obtain information about the rate of service usage in the system without requiring implementation of neither new nodes nor new messages to be exchanged by new or existing nodes.

摘要： A method is provided for use in an IP Multimedia Subsystem, IMS, in which a Serving 5 Call Session Control Function, S-CSCF, of the IMS cooperates with a Home Subscriber Server, HSS, of the IMS, to lock a user following a predetermined number of failed authentications of the user at the S-CSCF and/or to unlock that user thereafter, with any request received from the user at a node of the IMS where the lock is in effect and requiring an authentication challenge being caused by the node to be rejected. In one example, a locking signal is sent from the S-CSCF to the HSS, following the predetermined number of failed authentications, to indicate to the HSS that the user should be locked at the HSS. The locking signal could be carried by a Server Assignment Request, SAR, message. In another example, the user is unlocked at the S-CSCF in response to receipt of an unlock signal sent from the HSS to the S-CSCF. The unlock signal could be carried by a Registration Termination Request, RTR, message.
摘要翻译：提供了一种在IP多媒体子系统IMS中使用的方法，其中IMS的服务5呼叫会话控制功能S-CSCF与IMS的归属订户服务器HSS协作，以锁定用户跟随在S-CSCF处的用户的预定数量的失败的认证和/或以后解锁该用户，在IMS的一个节点处从用户接收到的任何请求被锁定，并且需要认证挑战是由节点被拒绝。在一个示例中，锁定信号从S-CSCF发送到HSS，遵循预定数量的失败认证，以向HSS指示用户应该被锁定在HSS。锁定信号可以由服务器分配请求（SAR）发送。在另一示例中，响应于从HSS发送到S-CSCF的解锁信号的接收，用户在S-CSCF处被解锁。解锁信号可以通过注册终止请求RTR来传送。

摘要： A method of handling SIP requests received by an IP Multimedia Subsystem network. The method comprises determining whether or not the SIP destination identity is within a range of identities owned by an operator of the network but is currently unallocated to a subscriber or service of the network and, if yes, routing the message to one or more SIP application servers within the network and implementing service logic at the application server(s) specific to a network owned but unallocated SIP identity.
