<P>PROBLEM TO BE SOLVED: To prevent double registration of information generated at the time of a retry in a remote management system for managing a state of a remote management target device with a remote management device via a communications network. <P>SOLUTION: A remote management target device and a remote management device share a retry waiting interval table. The remote management target device transmits a retry count and a transmission time. The remote management device obtains the retry count and the transmission time, and an initial transmission time from a retry waiting interval corresponding to the retry count and a received time. When received data is already registered in a DB (a device management table), the remote management device compares the received data with registered data; checks the following points: whether a value in the received data is equal to that in the registered data, whether a retry count of the received data is smaller than that of the received data by at least one, and whether an initial transmission time of the received data is newer than that of the registered data; and registers the received data only when at least one of the above points is not applicable. <P>COPYRIGHT: (C)2012,JPO&INPIT |
