ROUTING OF CALL MADE TO SUBSCRIBER

摘要

A service associated with a call terminating at a subscriber can be triggered from a network node serving the subscriber when the subscriber is registered in the network and has a serving network node. In order to trigger the service also when the subscriber is not registered in the network, the network is provided with a service function which triggers the service for the subscriber that is not registered in the network; and the call terminating at the subscriber that is not registered in the network is routed (3-2, 3-3) to this service function.
