Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of switching a driving operation mode for operating a control processing device having a duplex structure as a single duplex system under a certain condition, and further to a duplex control process. If the device contains multiple controlled devices,
The present invention relates to a control processing method by a duplex control processing device for a plurality of controlled devices, in which the controlled devices are subjected to distributed control processing by each control processing device that constitutes the duplex control processing device. ..

[0002]

2. Description of the Related Art In general, when some kind of system is constructed, a control processing unit as a general control unit of the whole system is constructed as a redundant system in order to improve its reliability. .. Control processor is often 2
Although it is configured as a redundant configuration, if the active system control processing device goes down due to some failure due to this, the standby system control processing device that was in the standby state until then is By functioning as a new active system control processing device, it is possible to prevent the entire system from going down. By the way, as the one relating to the redundancy of the control system device, there is, for example, "Revised digital exchange system" (August 10, 1989, published by The Institute of Electronics, Information and Communication Engineers, page 130).

[0003]

As described above, it is effective to configure the control processing device as a redundant one to the occurrence of a failure in the active control processing device. It is the processing capacity of the active system control processor itself. If the load on the control processing is almost constant at all times, the control processing device having the processing capacity corresponding to the load may be simply configured as a duplicate, but the load is expected to be temporary. If the above occurs intensively,
It is impossible to deal with an unexpected situation such as a part of control processing being discarded or a large delay in control processing.

A first object of the present invention is to provide a method for switching operation mode of a duplex control processing apparatus, which allows a control processing apparatus having a duplex configuration to be operated as a duplex type under a certain condition. To serve. A second object of the present invention is, when a plurality of controlled devices are accommodated in the duplex control processing device,
A control processing method for a plurality of controlled devices by a dual control processing device capable of performing a distributed control process on a plurality of controlled devices under a certain condition by using a duplexed control processing device as a single duplex type. To serve.

[0005]

A first object of the present invention is to operate a control processing device having a duplex configuration, which is in a duplex operation configuration, under a certain condition as a duplex operation configuration. It is achieved by merging. The above-mentioned second object is achieved by allowing a plurality of controlled devices to perform distributed control processing under a certain condition by using a control processing device having a duplex configuration as a single duplex type.

[0006]

The point is to make the control processing device of the duplex configuration, which is in the operating state of the dual duplex system, operate normally as the dual duplex system under certain conditions. It is a thing. As a result, the processing capacity of the control processing device having the dual structure is doubled in the normal state, and it is possible to easily deal with an unexpected load concentration. Therefore, when a plurality of controlled devices are accommodated in the control processing device having the duplex configuration and the load is temporarily concentrated, those controlled devices are controlled by two control processing devices. Since each can be distributedly controlled, the load on the load processing can be reduced as compared with the case where the control processing device is a duplicated set.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.
It will be described with reference to FIG. FIG. 3 shows a schematic configuration of an example of an exchange system to which the present invention is applicable. In this case, the subscribers 2 and 6 are connected via the concentrator 3, the communication path device 4, and the concentrator 5, and when a call is made, the control for enabling the call is (control). It is performed by the processing device 1. Incidentally, the signal device 7 is for generating an audible sound such as a ringing tone, and together with the concentrator 3, the communication path device 4 and the concentrator 5, each of them is a so-called communication path system device. is there. Thus, the processing device 1
The entire switching system is controlled by
Since the occurrence of a failure there leads to a system down of the entire immediate exchange system, the processing device 1 needs to be configured with redundancy (for example, a dual configuration).

However, it is effective to configure the processing processor 1 as a redundant one against the occurrence of a failure in the active (control) processing device, but the problem here is that the processing device 1 itself. Processing capacity (this processing capacity is the same as that for one processing apparatus). If the load on the control processing is almost constant at all times, it is sufficient to simply configure a processing device having a processing capacity corresponding to the load as a duplicated one, but even temporarily, the load is higher than expected. If it occurs intensively, some of the processing may be discarded, or the control processing may be delayed significantly. In order to cope with such an unforeseen situation, in the present invention, when the load unexpectedly concentrates or when the time zone during which the load concentrates is empirically known in advance, The idea is to distribute the load among the constituent processing devices.

Now, the present invention will be described in detail with reference to FIG.
FIG. 2 is a schematic configuration of an example of a switching system to which the present invention is applied, and FIG. 2 is a duplication control processing device operation / operation mode switching process according to the present invention, or a plurality of controlled devices (as described in this example. 2 is a flow chart of control processing by the duplexing control processing device for the communication path system device of FIG. As shown in FIG. 1, a processor equivalent to the above-described processing device 1 for comprehensively controlling the entire switching system is composed of two control processing devices 11 and 11 'of the same configuration in this example. While one of the control processors 11 and 11 'is operating as an active control processor, the other one is in a standby state as a standby control processor. There is. Here, the general operation of the control processing devices 11 and 11 'will be briefly described. For example, the control processing device 11 operates as the active control processing device, and the communication path system device 14 operates via the communication path system bus 12. In the case where all of the -1 to 14-n are controlled collectively, the control processing unit 11 'is in a standby state as a standby system control processing unit during that period. If some trouble occurs in the control processing device 11 in such a state, the control processing device 11 'which has been in the standby state until then operates as the active system control processing device, and the call A system in which all of the communication path system devices 14-1 to 14-n are comprehensively controlled through the road system bus 12 ', while the control processing device 11 is put in a standby state as a standby system control processing device. Is. At that time, the control processing device 11 in which a failure has occurred is promptly taken as a countermeasure for removing the failure, and is put in a standby state as a standby system control processing device.

When a failure occurs in the active control processor, the operation is generally as described above, but such an operation is not directly related to the present invention. In the present invention, assuming that no failure has occurred in any of the control processing devices 11 and 11 ', if a load is unexpectedly concentrated or a time zone during which the load is empirically concentrated Is known in advance, in order to perform distributed control processing on each of the communication path system devices 14-1 to 14-n,
Each of the control processing devices 11 and 11 'is intended to operate as the active control processing device. For example, when the control processing unit 11 is operating as the active control processing unit, unexpectedly, a concentrated load may occur.
If it is detected in the control processing device 11 '.
While the overload condition is detected, 2
The duplex / single duplex switching display signal 13 is sent from the control processing device 11 to each of the communication path devices 14-1 to 14-n. As a result, both the control processing unit 11 'and the control system operating unit are operated as the active system control processing unit. At this time, each of the communication path system units 14-1 to 14-n is controlled by any one of the control processing units 11 and 11'. In the case where it is set in advance, each of the communication path system devices 14-1 to 14-n can be decentralized and controlled by either the control processing device 11 or 11 ', so that an unexpected load is intensively generated. It can be easily dealt with. When the concentrated occurrence of the load is eventually stopped, the fact is notified to the control processing device 11 ',
The transmission of the duplex / single duplex switching display signal 13 to each of the communication path system devices 14-1 to 14-n is stopped. As a result, the control processing device 11 operates again as the original active control processing device, and controls all of the communication path system devices 14-1 to 14-n via the communication path system bus 12 as a whole. The device 11 'is placed in a standby state as a standby control processing device. Incidentally, in the above example, the distributed control for each of the communication path system devices 14-1 to 14-n is adopted only after the concentrated occurrence of the load is actually detected. It is clear that, even when is known in advance, similar distributed control may be adopted during the time period.

Here, the control processing device 1 will be delayed.

Thus, the distributed control processing for each of Nos. 1 to 14-n can be performed without any trouble. Also, the load detectors 11-4, 1
In each of 1'-4, the concentrated occurrence of the load is actually detected, and when the occurrence is detected, the duplex / single duplex switching display flip-flops 11-5, 11'-5 are both set. When the occurrence is stopped, the double / single switching switching display flip-flops 11-5 and 11'-5 are both in the reset state.
If the time zone when the load is concentrated is empirically known in advance, each of the load detection units 11-4 and 11'-4 may be configured as a timer.

FIG. 2 also shows a flow of the operation control mode switching processing of the duplex control processing apparatus according to the present invention or the control processing by the duplex control processing apparatus for a plurality of controlled devices. This is clear from the above description, so no particular description is necessary. However, if I add a note in particular, the "unused state of the communication channel device" in the flow is almost always in use, but it is as if it is in use at that moment. It means that there is.

Although the present invention has been schematically described above, the redundant configuration of the general control processing device is not limited to the duplication, and the present invention is generally applicable to the configuration of the duplication or more. ..
