IPC: H04W12/06
Filed: 2002-11-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a terminal unit for radio communication that easily joins a network, even if identification information of a radio access point, with which the unit desires to communicate with, is changed.  <P>SOLUTION: When a radio station terminal STA1 sends an authentication requesting message by using SS-ID "11111", a radio access point AP1 holding "11111" conducts authentication processing between the terminal STA1 and the point. However, since the WEP keys, respectively set to the terminal and the point, are different from each other, an authentication-denying message is returned. Then, the terminal STA1 receives beacon signals sent from a plurality of radio access points AP, keeps SS-IDs and receiving electric field intensities contained in the signals in a data base 801, and selects the SS-ID having the strongest receiving electric field strength among the SS-IDs except erroneously authenticated SS-IDs as a new SS-ID. In addition, the terminal makes an authentication request, using the newly set SS-ID.  <P>COPYRIGHT: (C)2004,JPO
