ABSTRACT:
Origination and incoming are regulated for each service in user units. An origination filter table stores contract service information indicating whether or not each service can be used and the maximum number of sessions that can be activated by the originator corresponding to each originator identifier (for example, SIP-URI). An incoming filter table stores incoming enable/refusal information and an originator identifier from which incoming is enabled or refused corresponding to each receiver identifier. A communication control section references the contract service information and the maximum number of sessions in the origination filter table based on the originator identifier in the message received from a communication terminal, determines whether or not the service indicated by service type information in the message can be used, and determines whether or not a new session can be established. The communication control section references the incoming enable/refusal information in the incoming filter table based on the receipt party and originator identifiers in the message and determines whether or not incoming is enabled.
