る。Referring to FIG. 3B, the central supervisory control unit 30 counts the traffic count counter 103 for counting the number of resources in use as a communication channel for each sector, and counts the number of times the traffic count is measured. Measurement counter 1 for traffic
04, and a continuous report counter for counting, for each sector, the number of continuous transmissions of an operation state notification message to be transmitted to the radio base station control station when the operation states do not match between the radio base station and the radio base station control station. 105 and the active SDM unit 91
In addition, the operation parameters pre-written in the standby SDM 92 are read, and the traffic measurement time and the maximum number of continuous reports are expanded in the working common memory unit 93 and the standby common memory unit 94 to register a traffic measurement timer. The parameter setting control unit 101 starts measuring the traffic based on the time-out notification of the timer, calculates the average value of the number of busy channels for each sector counted by the traffic calculation counter 103, and measures the traffic for all sectors. Traffic light measuring unit 102 and traffic light measuring unit 102
Each time the base station operation state is determined based on the measurement result, the traffic count counter 104 is counted up, and it is determined whether or not the traffic measurement for the measurement time developed in the common memory unit has been performed. If the condition is not satisfied, the measurement result is invalid. If the condition is satisfied, the measurement value is checked for each sector. If there is a sector with no traffic, the continuous report counter 105 is counted up and an operation status notification message is created. An operation status message notifying unit that creates and outputs an operation status notification message according to an instruction from the operation unit
And a wave stop instruction control unit 108 for instructing the wireless transceiver corresponding to the sector to stop transmitting radio waves when the operation state determination unit 106 determines that the operation state mismatch occurs. The working SDM unit 91 and the standby SDM 92 are provided for each wireless base station 10 so that the number of times of measurement of traffic and the number of continuous detections of inconsistency in operation status can be flexibly changed because the traffic volume differs depending on the installation location of the wireless base station 10.

The traffic measurement time and the maximum number of continuous reports are expanded, and the traffic measurement timer is registered (S403 to S405). When the traffic light measurement unit 102 receives the timer expiration notification of the traffic light measurement timer, the traffic light measurement unit 102 starts measuring the traffic light (S406 to S407). The traffic volume measurement unit 102
The number of resources being used as a traffic channel for each sector is counted up to the traffic calculation counter 103, and the average value of the number of busy channels counted for each sector is stored as a traffic measurement value of the corresponding sector. Is calculated (S501 to S506). The central monitoring control unit 30 has a timer function as hardware. The central monitoring control unit 30 includes a timer monitoring control unit (not shown) that supervises timers. The timer monitoring control unit performs all the control such as the timeout notification. Therefore, when the timer for the traffic measurement times out, the timer monitoring control unit notifies the traffic measurement unit 102 of the timeout, and the traffic measurement unit 102 receives the timeout notification of the traffic measurement timer from the timer monitoring control unit. Start measuring traffic.

３）。When the traffic volume for all the sectors has been obtained, the operation state determination unit 106 checks whether the operation state managed by the radio base station control station 2 and the operation state mismatch between the radio base stations 10 have occurred. Checking is started (S507). The traffic volume measured by the traffic volume measuring unit 102 cannot be determined from one measurement result because the interval of the measurement cycle is short. For this reason, each time the operation state mismatch monitoring process is executed, the traffic count counter 104 is counted up, compared with the traffic light measurement time value developed in the common memory unit, and indicated by the traffic light measurement time. Judge whether the traffic volume for the time was measured,
If the measurement time is not satisfied, it is determined that the measurement result information of the traffic light measurement value is invalid, and the operation status mismatch monitoring process is suspended until the measurement time is satisfied (S601 to S60).

The operation status notification flag to be turned on is turned on, the continuous report counter 105 of the corresponding sector is counted up, and operation status mismatch monitoring for all sectors is performed (S605).

Therefore, the operation status message notification unit 1
07 transmits an operation state notification message to the radio base station controller 2 to turn off the operation state notification flag (S40).
9-S411). After the transmission of the operation status notification message, if the value of the continuous report counter 105 managed for each sector exceeds the value of the maximum number of continuous reports developed in the common memory unit, the operation status of the radio base station 10 and the radio base station It is determined that a mismatch has occurred with the operation state managed by the control station 2 and that a call connection cannot be established for a long time, and the radio transmission / reception in charge of the corresponding frequency and the corresponding sector has been performed. For the machine 4n or 6n, the wave stop instruction control unit 108
Clears the counter of the corresponding sector of the continuous report counter 105 with the instruction to stop the wave (S412 to S415). When the radio transceiver 4n or 6n receives the stoppage instruction, the radio signal being transmitted is stopped, so that the control signal is not transmitted in the radio section (S416), and the mobile station is connected to another adjacent sector or another frequency.

きる。As described above, according to the present invention, the traffic is monitored in addition to the detection of a change in the operation state of the radio base station, so that there is a traffic even if the operation state does not change. If there is a mismatch between the operation status of the radio base station and the operation status managed by the radio base station control station, the operation status It is possible to shorten the time until the state mismatch is eliminated. In addition, when the state of no traffic continues for a long time, the mobile station stops the radio wave of the corresponding sector and the mobile station receives the control channel of the adjacent sector, so that the mobile station is connected to another adjacent sector. Alternatively, it can be shifted to another frequency.
