PROBLEM TO BE SOLVED: To obtain a channel switching method and channel switching system reduced in the time necessary for channel switching and processing amount. SOLUTION: Base stations 11 to 14 for forming radio zone by radiating plural narrow beam has a switching management table in which a switching candidate base station to be an object of channel switching for each beam and a switching candidate beam is stored along with a switching priority order, and a switching candidate base station and a switching candidate beam are selected using this switching management table. If there is a channel available for the selected switching candidate base station and switching candidate beam, a moving station 15 switches the using channel. Then, the switching priority order of the switching management tables had by the base stations 11 to 14 is updated depending on success or failure of the channel switching. |
