<P>PROBLEM TO BE SOLVED: To provide: a communication system capable of preventing a mobile terminal from being connected to a fake access point even when the fake access point is installed in a wireless LAN; a mobile terminal of the system; and a center of the system. <P>SOLUTION: The mobile terminal 400 receives a beacon, acquires disclosed SSIDs, and transmits the acquired SSIDs to a wireless LAN center 500 with SMS communication (S11-S16). The wireless LAN center 500 receives them, and identifies a first AP 100 of a pair for a second SSID by referring to a pair AP table 52 (not shown) (S17). Determination of overlapping where SSIDs of a plurality of APs are identical to one another is carried out (S18). When the SSIDs overlap, the first SSID of the first AP 100 and change notification of a WEP key are transmitted to the first AP 100 and the mobile terminal 400 (S19-S22). The mobile terminal 400 performs connection to the first AP 100 by the first SSID and the WEP key after the change (S24). <P>COPYRIGHT: (C)2011,JPO&INPIT |
