[2] Description of Operation The operation of the embodiment of the present invention will be described with reference to FIG. When an outgoing call or an incoming call of a telephone housed in the subscriber station device 3 is performed, the call processing control unit 11 sets the subscriber radio transmission path between the radio base station device 1 and the subscriber station device 3. In order to perform connection control and release control of, using the wireless channel allocated by the channel management unit 13,
A call connection process is performed between the wireless base station device 1 and the subscriber station device 3. The call connection information at this time is transmitted to the traffic monitoring unit 14.
Notify.

The traffic monitoring unit 14 includes the call processing control unit 1
The traffic is monitored based on the call connection information notified from No. 1 and a traffic value, which is the frequency of use of the communication radio channel, is calculated. Radio relay station device 2 and subscriber station device 3
In the status monitoring, the device monitoring unit 12 transmits a status request order to each device, receives a status information response sent from each device corresponding to the order, and transmits the information to the remote monitoring control device 4. By doing. At this time, a wireless channel assigned by the channel management unit 13 is used as a wireless channel for transmitting the information request order to each device.

The channel management unit 13 includes a call processing control unit 11
Allocates a wireless channel used for controlling a wireless channel. Further, the channel management unit 13 compares the traffic value calculated by the traffic monitoring unit 14 with the radio relay station device 2 and the subscriber station device 3 accommodated in the system.
And the state of the radio channel for communication managed by the channel management unit 13, the number of radio channels for communication to be allocated for state monitoring is determined. As an example of the determination method, a table for determining the number of communication radio channels to be used for status monitoring based on the traffic value and the number of devices in the system is provided in the memory of the radio base station device 1, and the status is determined according to this table. Determine the number of call radio channels to be assigned for monitoring. Then, according to the state of the call wireless channel managed by the channel management unit 13, the number of unused wireless call channels determined to be allocated for state monitoring is allocated as a state monitoring wireless channel.

The device monitoring unit 12 uses the state monitoring wireless channel allocated by the channel management unit 13 for the wireless relay station device 2 and the subscriber station device 3 and uses the wireless relay station device 2 and the subscriber station device 3. The status request order is sent to each device via the wireless signal transmission / reception unit 15 in order to monitor the status of the device. By providing, for example, a status monitoring flag in the status request order at this time, the status monitoring that the radio channel used when transmitting the status request order is used for status monitoring instead of the call processing radio channel for the call processing order is used. Indicates that this is a wireless channel. Upon receiving this order, the wireless relay station device 2 and the subscriber station device 3 determine the status monitoring flag and determine that the received wireless channel is a status monitoring wireless channel used for status monitoring. recognize. If the received order is the status request order, the status information of the device is transmitted as a response using the received wireless channel. The device monitoring unit 12 also monitors the status of the devices in the system by converting the status monitoring information received by the wireless signal transmission / reception unit 15 into a format for transmission to the remote monitoring control device 4 and transmitting the format.

[0018]

As described above, according to the present invention, the time required for the radio base station apparatus to detect a change in the state of the radio relay station apparatus or the subscriber station apparatus can be reduced, and the remote monitoring control apparatus can be immediately notified. It has the effect of being able to.

The reason is that the traffic monitoring means monitors the frequency of use of the communication radio channel to determine the traffic value, and when the usage of the communication radio channel is small (when the traffic is small), the channel management means is used. This is because a plurality of communication radio channels are allocated as status monitoring radio channels in accordance with the traffic value.
