Patent ID: 7650162

Claim:
A mobile terminal for a wireless communication system including an access point communicating on a designated one of a plurality of frequency channels, wherein the mobile terminal communicates with said access point on the same received frequency channel by receiving radio waves transmitted by said access point and comprises: storage means storing relative priority data for a frequency channel search which is set respectively for said plurality of frequency channels, the mobile terminal generating, on the basis of the relative priority data stored in said storage means, frequency channel search sequence data set up so that the number of times of appearance becomes greater for frequency channels for which the relative priority data are set higher, the mobile terminal carrying out a search of the frequency channels with which communication is possible, following the frequency channel order of the same generated frequency channel search sequence data; and a positioning device acquiring information on its own position and an access point database consisting of position information on the position at which said access point is installed, searching said access point database on the basis of current position information obtained by means of said positioning device, obtaining the access point which is next to communicate and the frequency channels thereof, and updating said relative priority data on the basis of the obtained frequency channel information.
