PROBLEM TO BE SOLVED: To reduce the number of times of radio channel switching, and to improve throughput by detecting an interfering wave from the other radio communication equipment, holding the switching of a radio channel since the interfering wave is detected until a prescribed time passes, and switching the radio channel to the other radio channel when the interfering wave is still detected even after the lapse of the prescribed time. SOLUTION: Electric field strength on a radio channel for operating connectionless communication by a receiver 11 and a transmitter 12 is measured by an envelope detector 13. When it is judged that the electric field strength is beyond a reference value by a comparator 14, and a signal transmitted to another radio base station 11 is received by the receiver 11, it is judged that interference is generated, and count is started by a counter 100. When it is judged that interference is still generated even after a holding time in which the count value of a time is set, a message signal is generated by a message generating circuit 15, and transmitted to another mobile station 2, and the radio channel is switched by a channel control circuit 16. |
