Claim:
A wireless communication system comprising multiple wireless access apparatuses equipped with a wireless communication function and a monitoring apparatus monitoring the wireless access apparatuses, wherein the monitoring apparatus judges whether communication with the multiple wireless access apparatuses is possible, stores apparatus identification information, that has been given to the wireless access apparatuses, so that wireless access apparatuses with which communication is judged to be possible can be identified, into a neighborhood database, if there is apparatus identification information that is not stored in the neighborhood database, among apparatus identification information stored in a registration database in which apparatus identification information has been given to wireless access apparatuses so that wireless access apparatuses registered as monitoring targets of the monitoring apparatus can be identified, performs the judgment again for a wireless access apparatus to which the identification information is given, after a predetermined time elapses, and, if there is no apparatus identification information that is not stored in the neighborhood database among apparatus identification information stored in the registration database or if the judgment is performed again for a predetermined number of times, copies the apparatus identification information stored in the neighborhood database to the registration database and stores the apparatus identification information in the registration database, and the monitoring apparatus requests that the apparatus identification information be given wireless access apparatuses which are adjacently connected to the multiple wireless access apparatuses, from the multiple wireless access apparatuses and, when the apparatus identification information is transmitted from the wireless access apparatuses in response to the request, judges that communication with the wireless access apparatuses to which the apparatus identification information is given is possible, and when the request is issued, the wireless access apparatuses transmit the apparatus identification information that has been given to the wireless access apparatuses which are adjacently connected to the wireless access apparatuses, to the monitoring apparatus.
