An apparatus is provided that includes a processor configured to maintain a first implicit registration set for a first apparatus, where the first implicit registration set includes a first identity unique to the first apparatus and a shared identity. The processor is also configured to maintain a second implicit registration set for a second apparatus, where the second implicit registration set includes a second identity unique to the second apparatus and the shared identity. In this regard, the first and second implicit registration sets may be maintained to enable registration of the first and second apparatuses with a network such that each of the first and second apparatuses are configured to receive communication requests to the respective first and second identities, and such that both of the first and second apparatuses are configured to receive communication requests to the shared identity.

Apparatus, method and computer-readable storage medium for registering user identities

A method, system and network device routes a message to a temporarily unavailable network user, wherein a subscription to a registration state of the network user is initiated if the network user is indicated as being unavailable. Then, a notification is generated, when the registration state of the network user is changed to indicate a state when the network user is available again or when the network user is registered again, and the message is routed to the network user in response to receiving the notification. Thereby, network elements or servers generating messages can be informed about the connection state of the network user.

Method, system and network device for routing a message to a temporarily unavailable network user

The invention is a system and method of controlling an access of a subscriber to a network. The method includes sending an identification of the subscriber and a level of access to be provided to the subscriber from a visited network of a plurality of networks () connected to a home network (); in response to the identification of the subscriber and a level of access to be provided to the subscriber, storing a subscriber profile of the authorized of access to be provided to the subscriber; and controlling access of the subscriber to any network dependent upon a comparison of access to be provided to the subscriber and the stored subscriber profile.

System and method of controlling application level access of subscriber to a network

The invention relates to a communication system and method wherein a user equipment contains, or is provided with, a list of items of service-related information. The list of service-related information represents a list of service provider names, services and/or service types or the like. When intending to establish or modify a session or connection or use a service, the user equipment selects, in one of the embodiments, an item from the list and performs a DNS query to resolve the name of the selected item to an IP address which then is used for set-up. The list may be provided by an DHCP server or in a PDP context message. The list may comprise one or more service provider default names, in particular for visited and home networks.

Communication system and method for establishing a connection to a serving network element

The invention relates to a service provisioning method in a communication system. In the method information regarding a communication control entity capable of servicing a user of the communication system is received at a first entity associated with the communication system from a storage entity. Based on said information, an originating request is then signalled from the first entity to the communication control entity.

Service provisioning in a communication system

Methods and apparatus, including computer program products, are provided for emergency call support. In one aspect there is provided a method. The method may include a home subscriber server receiving a first message comprising a generated value representing a session transfer number. The session transfer number may relate to a transfer of an emergency session from a first network to a second network. The method may further comprise a home subscriber server updating a user profile with the generated value representing the session transfer number for the emergency session. The user profile may be stored in the home subscriber server. The method may further comprise a home subscriber server sending a second message comprising the generated value representing the session transfer number. Related apparatus, systems, methods, and articles are also described.

Method for SRVCC emergency call support

A service control element stores a user filter criterion. When it receives a session request identifying the user, it checks whether the session request matches the user filter criterion, and outputs the session request to a defined service platform when the session request matches the user filter criterion. The element is arranged to retrieve, before forwarding the request to the service platform, a capability information element that indicates the dynamic capability of a user to utilize the service provided by the service platform. If the information element indicates that the user is not capable to utilize the service provided by the service platform, the session is terminated. Incoming messages can be appropriately managed already in the network element responsible for service control, and thus additional load and unnecessary charging considerations can be avoided.

Method and element for service control

Embodiments provide a method and apparatus wherein a proxy control function may forward an emergency session to a serving control function, the serving control function forwarding the session to a default emergency control function. The default emergency control function may return an address or identity of an emergency control function or may forward the session to an emergency control function.

Call routing

The invention provides a method and system for routing a message or a set of messages or a session from a first equipment connected or registered to a first network, to a second equipment connected or registered to a second network. The first network includes a network entity which checks requirements of the message or set of messages or session, and decides on the routing depending on the check result. The checked requirements may include media requirements of the message or set of messages or requested session. The checked requirements can also include QoS requirements of the message or set of messages or requested session.

Optimized routing between communication networks

The present invention is directed to a method and system for authorizing access to information of a user. The system includes a first network entity and a second network entity. The first network entity sends a request for information of a user to the second network entity. The second network entity receives the request for information of the user, verifies that the first network entity is authorized to receive the requested information, and generates a response authorizing the request if the first network entity is authorized to receive the information. The verifying may include comparing the first network entity against all non-barred public user identities of the user, comparing the first network entity against all network entities identified in a previous request, and comparing the first network entity against all application servers not belonging to third-party providers outside a network to which the user is connected.

Method and system for authorizing access to user information in a network

According to one aspect, a communication network system comprising at least one first network and at least one second network providing application services over the first network is described. The system comprises first network means (GGSN) for receiving a message associated with an IP address allocated by the first network from the second network, for detecting that there is no active communication channel for this IP address which is allocated to a user equipment, and for sending an indication that the user equipment is not reachable through this IP address to the second network. The system further comprises second network means (P-CSCF/PCF) for receiving this indication.
