It is equipped with a panel control table (PCT) that stores status information such as maintenance information, ALM information, and blockage information. As shown in FIG. 7, the mounting position is divided in units of shelves and by the slot number in each shelf. As shown in FIGS. 8, 9, and 10, status information is stored in each panel.

Next, the operation will be described. The software of the base station supervisory controller uses the real-time monitor of the operating system to perform multi-CPU call processing, supervisory control of the inside of the device and the base station, regulation of traffic, calling, etc., system restart, program data transfer. Etc. are configured to execute driving processing.

The load module is set in the program load area of the local memory 31-1 (31-2) shown in FIG. 11 of the semi-fixed memory panel (SDM) 30-1 (30-2). Is a RAM of the main memories 11-1 to 11-4 shown in FIG. 5 of each central control panel (CPU) 10-1 to 10-4 when the respective central control panels (CPU) 10-1 to 10-4 are started up. The regions are loaded simultaneously.

In this state, the common memory panel (GM) 60-1 stores call information for making a call connection from the base station to the mobile station and control information for monitoring and controlling the base station.
When an interrupt from (60-2) for activating a process that needs to be constantly performed when the timer times out, an interrupt at the time of a status change from the monitor control panel (SOP) 50, etc. occur, this is used as a trigger for central control. Panel (CPU)
The interrupt process to 10-1 to 10-4 is started, the function task corresponding to the interrupt factor is dispatched, and the predetermined task process is executed. The central control panel (CP
U) 10-1 to 10-4 are normally in an interrupt waiting state (idle state).

The supervisory control panel (SOP) 50 continuously searches the global memory 61-1 (61-2) of the common memory panel (GM) 60-1 (60-2) to obtain the status information of each constituent panel. Is stored in the panel control table (PCT) of the global memory 61-1 (61-2) shown in FIG. 7, and the latest state change information of each panel mounted on the shelf is read out, 21 compares the corresponding shelf number and the old state information of the panel number from the old state table of its own local memory 51, and if there is a change, its own local memory 5

-4, for example, when receiving an interrupt from the supervisory control panel (SOP) 50, judges from the vector number shown in FIG. 2 and activates the supervisory control task. The supervisory control task searches the busy bit (B) column of the status change table of the local memory 51 of the supervisory control panel (SOP) 50 shown in FIG. 21, and when it is “1”, the old state information in the old state column is used. The shelf number designated by the interrupt from the supervisory control panel (SOP) 50 is compared again with the latest state information corresponding to the slot number to determine the state change.

For example, the debug panel (D
B) When the "ALM" information of 20 is detected, the global memory 61-1 of the common memory panel (GM) 60-1 (60-2) shown in FIG. 7 is reset to reset the debug panel (DB) 20. The slot number of the shelf in which the debug panel (DB) 20 is mounted is searched from (61-2), and the control monitoring panel (SOP) 50 shown in FIG. 21 is searched.
"$ 0" indicating that the debug panel (DB) 20 is reset in the busy bit (B) column of the local memory 51 of
The debug panel (DB) 20 is reset by writing "0" (see FIG. 8). At this time, the status change report (signal contents, debug panel number,
ALM information) is transmitted.

Thus, the central control panel (CPU) 10
As shown in FIG. 20, each of -1 to 10-4 is configured to perform an interrupt process from each panel in one hand.

[0021]

As described above, according to the prior art, the central control panel (CPU) executes all interrupts from all the configuration panels as in the module configuration shown in FIG. Due to the increase in the traffic of call processing tasks accompanying the increase in the number of transmissions and receptions with other devices via the base station due to the rapid increase in the number of subscribers, and the increase in the traffic of monitoring tasks accompanying the expansion of base stations, the CPU is busy during the high traffic hours. The processing capacity of is close to the limit.

For example, as shown in FIG.
When the power to another shelf (not shown) having the same configuration as the shelf 4 shown in FIG. 4 is cut off, a maximum of 28 panels (4 Bch data channel relay panels, 24 Rch data channel relay panels) are not mounted. The status change interrupts are simultaneously applied to the central control panels (CPUs) 10-1 to 10-4, and in the worst case, the processing capacity may be exceeded and a system down may occur.

Further, since the supervisory control task usually has a higher processing priority than the call processing task, the processing of the call processing task is delayed, and the Bch data channel relay panel (BDU) and the Rch data channel relay panel (RDU). The transmission / reception buffer (not shown) included in the device overflows and the transmission / reception signal is discarded, so that the call loss rate becomes high.

Further, when a base station whose monitoring type monitored by the base station control device is different from the conventional one is added or when abnormal processing in the operation management system task is added, the semi-fixed memory panel shown in FIG. Since the program area of the local memory 31-1 (31-2) of the 30-1 (30-2) is insufficient, there is a high possibility that it will be difficult to add a function.

The object of the present invention is to increase the traffic of call processing tasks by dividing the various supervisory control processes for mobile stations and the various supervisory control processes inside the base station supervisory control device by different CPUs. , It is possible to sufficiently cope with the increase in the traffic of the monitoring task accompanying the expansion of the base station, and by executing the monitoring control task processing according to a predetermined priority, it is possible to suppress the call loss rate due to the delay of the call processing task processing. To provide a device.

When the status change report information is edited and set in the information section column of the maintenance monitoring terminal transmission buffer and the status change report information “present” is set in the busy bit section, and when there is no difference, from the state change report information "Reported" is set in the status change report column of the report sequence management table corresponding to the slot number of the extracted shelf number, and the control instruction information extracted from the maintenance monitoring terminal reception buffer is other than the status change report response information. Then, it is determined whether or not it is the automatic control report response information, and when the determination result is the automatic control report response information, the shelf number and the slot number are extracted from this automatic control report response information. “Not controlling” in the control status column and priority in the priority column of the control sequence management table corresponding to the shelf number and slot number. It is characterized in that the control instruction information receiving task process is executed by setting a tee “none”.

The second CPU extracts the setting contents of the shelf number column, the slot number column and the control information column corresponding to the priority and panel number designated by the loop counter from the control information table and extracts the setting contents. The presence or absence of the control information setting in the control information column is determined, and when the determination result is the control information setting “present”, the content of the control information is identified,
It is determined whether or not this control content is controllable, and when the determination result is uncontrollable, the panel control response disable information is edited and set in the information section of any free buffer of the maintenance monitoring terminal transmission buffer. Set the control response disabling information “present” in the busy bit column, clear the shelf number column, slot number column and control information column of the control information table, and specify with the loop counter when the control content is controllable After setting the control contents extracted from the control information table in the panel status information column of the panel control table corresponding to the shelf number and slot number, the panel control response enable information is edited and the maintenance monitoring terminal is transmitted.
