Abstract
A server 3b for controlling a gateway 2 connecting a transport layer and an IP network has the function of accessing a service control point (SCP) 4 via a service control gateway 1a. A server 3 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 11 managed by the server 3a, 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.
