PROBLEM TO BE SOLVED: To quickly evade the interference and to carry on the communication without changing the radio frequency of plural transceivers against occurrence of the interference. SOLUTION: A radio base station 500 periodically retrieves the fresh interference evading destination radio frequency after sensing a carrier via a receiving circuit 503c and stores these retrieved radio frequency in a storage means 502c. The station 500 also reports and stores the fresh evading destination radio frequency which are periodically retrieved by the report signals to its follower radio mobile station. When the station 500 or the follower mobile station detects an interference disturbance, both stations quickly switch the operating radio frequency to the interference evading destination radio frequency to evade the interference without switching a transceiver unit TRX. |
