無線通信システム、チャネル選択装置、基地局及びチャネル選択方法
Document Type and Number:
Japanese Patent JP6500415
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication system for selectively notifying a frequency channel that does not fall into an incommunicable state by repeating the detection of interfering foreign waves and switching of frequency channels to a plurality of base stations for using a prescribed frequency channel mounted on a mobile object to wirelessly communicate with a radio terminal, a channel selection device and a plurality of base stations, and a channel selection method for selecting a frequency channel that does not fall into an incommunicable state by repeating the detection of foreign waves interfering the plurality of base stations and switching of frequency channels.SOLUTION: When receiving information of channel interference from a base station, a channel selection device records correspondence among foreign waves, an interfered frequency channel and an area showing a position of a mobile object at that time, and selectively notifies a frequency channel that does not interfere with the foreign waves on the basis of the position of the mobile object to the base station which transmits the information of channel interference.SELECTED DRAWING: Figure 1
