PROBLEM TO BE SOLVED: To provide a dynamic channel mobile communication system with which priority for selecting channels is hardly disordered by the influence of inter-channel interference. SOLUTION: When a speaking request is generated, according to the previously decided selection priority, a channel selection circuit 26 retrieves any idle channel with which the power ratio of desired wave/interference wave gets higher than a prescribed value. The order of selection is previously decided from the channel with least inter-channel interference. Thus, in comparison with the case that the order of selection is decided at random without considering the inter-channel interference, the order of selection is more hardly disordered by the inter-channel interference. Thus, the conditions of improving the utilization efficiency of frequency can be formed for frequently repeatedly using the channel at the high rank of selection for a mobile station closer to the base station.
