PROBLEM TO BE SOLVED: To provide a radio communication system which can enhance reliability of a system as a whole, and can enhance efficiency of maintenance work by a method where a solution is given, in that an unconditional change during usage is a source of troubles at parameter setting change as the problem in prior art, and as the change is simply given up when in usage, maintenance work efficiency is poor, and then the setting change is carried out, in correspondence with a usage state of parameters. SOLUTION: In a radio communication system, when change designation of operational parameter is received by a united controller 4, the controller 4 determines whether such parameter is in usage, and if it is in usage, an alarm message is notified to a maintenance terminal 5, and the controller 4 monitors a usage termination of the operational parameter, and at the time of termination, the operational parameter of an operational parameter memory part 41 is changed. |
