COMMUNICATION SYSTEM, WIRED COMMUNICATION DEVICE, CONTROL METHOD, AND CONTROL PROGRAM

摘要

An AP (10A) regularly outputs a beacon. A wireless communication terminal (20A) receives the beacon and then uses a GPS or the like to specify the location of said terminal. The wireless communication terminal (20A) estimates the location of the AP on the basis of the field intensity of the received beacon and on the basis of the location information of said terminal. The wireless communication terminal (20A) then associates the estimated AP location information with AP identification information that is included in the beacon, outputs the associated information as a location information table to a database (50), and registers the associated information in the database. Meanwhile, a router (13A) acquires identification information for APs connected to said terminal. The router (13A) uses the acquired identification information for each of the APs to consult the location information table in the database (50) and acquires (S305) associated location information for each of the APs. The router (13A) then acquires the location information of said terminal on the basis of the acquired location information for each of the APs and transmits the location information of said terminal to a router (1).
