There are provided measures for enabling/realizing service continuity in a centralized service network system. Such measures exemplarily comprise detecting a deregistration request for deregistering a terminal with respect to a first switching entity from a registration in which the first switching entity is registered for the terminal as a contact point for centralized services, starting a waiting timer for waiting for a registration request for registering the terminal with respect to a second switching entity upon detection of said deregistration request, and re-registering the terminal in the registration such that the second switching entity is registered for the terminal as a contact point for centralized services upon detection of the registration request for registering the terminal with respect to the second switching entity before expiry of the waiting timer.

Service continuity in centralized service network system

The invention relates to an apparatus, method and a computer program product for establishing a request for a session by an application server, determining by an emergency related local service function that the session includes an emergency session, wherein the emergency related local service function is co-located at the application server, and, transmitting the request for the session to an emergency call state control function of the internet protocol multimedia subsystem based on the determination.

Emergency service in communication system

The present invention refers to a method, an apparatus and a computer program product for relaying CAMEL related messages in a telecommunication network, wherein received CAMEL related messages and corresponding subscriber data are analyzed (S), the received CAMEL related messages are translated (S) in non-Camel messages, the non-Camel messages are relayed (S) to a service delivery framework on the basis of the ana-lyzing result and non-CAMEL responses are received (S) from the service delivery framework. The non-CAMEL responses are re-translated into standard CAMEL operation responses (S), which are sent to initiator of the received CAMEL related message (S).
