COMMUNICATION CONTROL METHOD IN CONNECTION-TYPE COMMUNICATION, RELATED RELAY DEVICE, AND ACCOUNTING MANAGEMENT DEVICE

摘要

When a gateway server (40) detects disconnection of a TCP connection (A) from a mobile telephone device (10) to the gateway server (40) while relaying an HTTP communication between the mobile telephone device (10) and a content server (70), the gateway server (40) continues connection of a TCP connection (B1) from an accounting management server (50) to the gateway server (40) until the gateway server (40) receives accounting information for the HTTP communication until the TCP connection (A) is disconnected.
