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

Notifying the HSS of failure of connectivity request for a packet data session

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

Service aware overload handling in a communication network

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.

End user controlled multi-service device priority setting

A report message () is transmitted between a control node () of a first network and a subscriber server node (). The report message () indicates granted or failed authorization of a subscriber to establish a packet data session with a second network via an access point node.

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.

Home communication network determination

A service indication mechanism is described for use by IP Multimedia Subsystem, IMS, codes () of an IMS network () in routing a terminating call in a network comprising a circuit switched, CS, network () and an IMS network (). On receipt of a Service Initiation Protocol, SIP, message from a second IMS node (), the SIP message including a called user number associated with the call (A), a SIP Uniform Resource Identifier, URI, and the call services for the called user from a user profile database is retrieved (A). 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 (A), the SIP message is transmitted with the second SIP-URI to a third IMS node (). On receiving the transmitted SIP message, the third IMS node () 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 () and whether to suppress insertion of a prefix to a CS routing number of the called user. The third IMS node () transmits to a CS node () 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 (B).
