Service provision system

Abstract

A voice communications request from a calling party is received by the access reception unit of a gatekeeper and is transferred to an access management unit. The access management unit judges whether the utilization registration of the terminal of a called party is made by referring to an address conversion unit, a utilization registration management unit and a user profile information management unit, and if the utilization registration is not made, the access management unit makes a service selection unit select a service. The selected service is provided by a service start unit through an IP application service provision unit or a call control service provision unit, and the provision of the service is reported to the calling party by a service provision information notification unit. By this service, the called user can know that there has been an incoming call from the calling party in some way.
