Abstract
A server for controlling a gateway connecting a transport layer and an IP network has the function of accessing a service control point (SCP) via a service control gateway . A server for controlling terminals on the IP network stores information of correspondence between telephone number of a terminal and the IP address. When a signal including number information which requires an access to the SCP is received from a terminal managed by the server , an interrogation request is multicasted to the other servers each having the function of accessing the SCP. A server which has sent a response signal accesses the SCP via the service control gateway to provide an IN service process.
