CONNECTION CUTTING METHOD AND ASSOCIATED LINK CUT REPORTING METHOD

摘要

A gateway server 140 immediately releases a TCP connection A from a portable phone 110 in a case of receiving, from a base station 120 or a gateway switching station 130, a disconnection notifying signal designating that a wireless link between portable phone 110 and base station 120 or a wired link between base station 120 and gateway server 140 has been disconnected, while relaying HTTP communication between portable phone 110 and content server 160.
