Abstract: A report message (304) is transmitted between a control node (107) of a first network and a subscriber service node (109). The report message (304) indicates granted or failed authorization of a subscriber to establish a packet data session with a second network via all access point node.

Abstract: A node (100) of a communication network receives a request (101) relating to one of multiple services. Further, the node (100) determines whether an overload with respect to the service is present. In response to determining absence of an overload with respect to the service, the node (100) forwards the request (101) for further processing. In response to determining presence of an overload with respect to the service, the node (100) responds to the request with a failure message (102) indicating that the request was not processed. The failure message (102) comprises an indication of a time window after which the request (101) may be retried and an identifier of the service to which the request (101) relates.

Abstract: A communication network allows an end user to dynamically select a user device among user devices associated with the user's subscription as the primary user device by defining a primary capability tag or attribute. Selection of a user device sets the primary capability tag of the selected user device, which is published towards an application server. The application server notifies all other user devices in the group of devices. If a previous user device in the group of user devices was set as the primary user device, then, in response to the notification, the previous user device performs a re-registration with the network removing the previous user device as the primary user device for the services associated with the user subscription. The selected user device also performs a re-registration/registration with the network so all incoming requests for services associated with the user subscription are sent to the selected user device.

Abstract: System, methods, nodes, and computer program for determining a home network of a UE roaming in a visited network are described. The UE sends a session invitation to a further UE. The method comprises receiving, by a control node in the home network, the session invitation. The method further comprises adding, by a control node in the home network, an indication of the home network identity and an indication for session invitation loopback routing, to the session invitation. The method further comprises sending, by a control node in the home network, the session invitation towards the visited network. The method further comprises receiving, by a control node in the visited network, a session invitation from the home network. The method further comprises determining, by the control node in the visited network, the home network based on the indication of the home network identity.

Abstract: A service indication mechanism is described for use by IP Multimedia Subsystem, IMS, codes (201, 204) of an IMS network (106) in routing a terminating call in a network comprising a circuit switched, CS, network (107) and an IMS network (105, 106). On receipt of a Service Initiation Protocol, SIP, message from a second IMS node (202), the SIP message including a called user number associated with the call (A1), a SIP Uniform Resource Identifier, URI, and the call services for the called user from a user profile database is retrieved (A2). A second SIP URI is generated by including a service indicator of the called user in the received SIP URI, the service indicator representing the call services of the called user (A3), the SIP message is transmitted with the second SIP-URI to a third IMS node (204).

Abstract: Methods and apparatus are provided for operating a network element in an Internet Protocol Multimedia Subsystem network including a plurality of application servers. The network element receives a user request associated with a user. The user request is applied to a collection of Initial Filter Criteria associated with the user. If an Initial filter Criteria fires, then normal processing of the user request continues. However, if none of the Initial Filter Criteria fires, then default triggering logic determines the session associated with the user request is not recognised or is unknown. The default triggering logic applies the user request to one or more default iFCs, which include selection criteria defining one or more rules or conditions associated with rejecting or processing the user request (e.g. forwarding to an application server or continuing processing the user request at the network element).

Abstract: Methods and apparatuses for performing domain resolution prior to dispatching a request. A request from an Application Server (AS) is received. The AS and a network node are present in a first network domain. At least one target network domain is determined based on at least one domain indicator in the request. The domain indicator being associated with at least a part of the request, wherein the target network domain is one of: the first network domain and a second network domain. Then, the at least part of the request is dispatched, to at least one subscriber server present in the determined target network domain(s).

Abstract: Methods and systems are provided to reduce service delays in wireless communications networks. A method for gathering information associated with a user equipment (UE) at a node which is a part of a mobile communication network, the method includes: receiving a message at the node; and prefetching information associated with the UE upon receipt of the message, wherein prefetching includes transmitting a request for the information associated with the UE and receiving a response to the request for the information associated with the UE.

Abstract: A method of securing a mobile wireless telecommunication device to restrict access to data stored in the device. The method including registering the device with a network-based server associated with a given user. In the event that the user wishes to restrict access to data stored on the device when the user does not have access to the device, but has access to an alternative communication device, the user is authenticated, via said alternative communication device, to an IP Multimedia Subsystem (IMS) network and, on the basis of such authentication, the user is allowed to access the server and send to the server an instruction to lock the mobile wireless telecommunication device.

Abstract: According to a first aspect of the present invention there is provided a method of routing a call from an IP Multimedia Subsystem network to a circuit switched network. The method comprises, at a circuit switched carrier select node of the IP Multimedia Subsystem network, receiving a session establishment request (S1), determining if the request includes a circuit switched carrier identifier (S2), and, if not, identifying a circuit switched carrier for the intended destination of the request (S4), identifying a gateway control node responsible for a gateway node connected to the circuit switched network of the identified circuit switched carrier (S5), including in the request a circuit switched carrier identifier for the identified circuit switched carrier (S6), and forwarding the request towards the gateway control node (S8).
