<P>PROBLEM TO BE SOLVED: To provide a configuration of a relay server used for a relay communication system constituted by a plurality of relay servers, the configuration enabling a continuous operation of the relay communication system without changing the setting of a relay server to be managed even when the relay server on a management side stops. <P>SOLUTION: A center backup terminal (relay server) 6 stores management information and is switchable between states where the center backup terminal 6 operates as a master and as a backup. When operating as the master, the center backup terminal 6 registers network information of itself and master-identification information in an external server. When operating as a backup, the center backup terminal 6 registers the network information of itself and backup-identification information in the external server. When the state in which the center backup terminal 6 operates as the master is switched to the state in which the center backup terminal 6 operates as the backup, the center backup terminal 6 transmits the management information to a center terminal 5 which operates as the master. <P>COPYRIGHT: (C)2013,JPO&INPIT |
