Claim:
A radio base station monitoring method for monitoring a radio base station, the method comprising: step A of causing a first radio base station to monitor common control channels of one or more second radio base stations which exist at a periphery of the first radio base station and to detect a second radio base station whose common control channel has been newly detected and a second radio base station whose common control channel has no longer been detected as a second radio base station with change; step B of causing the first radio base station to notify a network device of information on the second radio base station with change; and step C of causing the network device to stop an operation of at least one of the first radio base station and the second radio base stations by using information on the second radio base stations associated with the first radio base station and the thus-notified information on the second radio base station with change, wherein, in the step C, the network device compares the number of the second radio base stations with change with the number of a rest of the second radio base stations among the second radio base stations associated with the first radio base station, judges which of an installation location of the first radio base station and that of the second radio base station with change has been moved on the basis of a result of the comparison, and stops the operation of the radio base station having been judged that the installation location thereof has been moved.
