PROBLEM TO BE SOLVED: To control communication of a connection type so as to suppress increase in traffic of a network and prevent wasteful occupancy of network resources. SOLUTION: A gateway server 140 relays HTTP communication between a mobile telephone 110 and a content server 160. During the relaying, if the gateway server 140 receives, from a base station 120 or a gateway exchange 130, a cut reporting signal representing that a radio link between the mobile telephone 110 and the base station 120 or a cable link from the base station 120 to the gateway server 140 is cut, the gateway server 140 cuts the TCP connection A to the mobile telephone 110.
