摘要： Method and arrangements for performing domain resolution prior to dispatching a request. A request from an Application Server (AS) is received. The AS and the 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 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).

摘要： 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). On receiving the transmitted SIP message, the third IMS node (204) detects whether the service indicator is included in the SIP URI, and applies the service indicator to a plurality of policy rules for indicating whether the terminating call should be routed to the CS network (107) and whether to suppress insertion of a prefix to a CS routing number of the called user. The third IMS node (204) transmits to a CS node (206) a SIP message including the CS routing number without the prefix when a routing policy rule associated with the service indicator indicates suppression of the prefix (B5).

摘要： 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.

摘要： 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 re-quest 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.

摘要： 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).
