DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a status management system for a communication device, and more particularly to a status management system for managing a hierarchical upper communication device, a number of middle communication devices and a number of lower communication devices by a status monitoring device. The present invention relates to a status information system of a communication device in which status information from a higher-level communication device to a status monitoring device is simplified and a processing speed is improved.

2. Description of the Related Art Generally, as shown in FIG. 4, a hierarchical communication system has a structure of a middle communication device group including a higher communication device 1 and middle communication devices 2A to 2K belonging to the higher communication device 1. 2, lower communication devices 3A, 3M and lower communication devices 3B, 3N belonging to the respective middle communication devices 2A, 2K.
And a lower communication device group 3 composed of Here, the upper communication device 1 receives the status information of the middle communication device group 2 and the lower communication device group 3 and sends out the status information of all the communication devices to the status monitoring device 4 in the middle and lower order.

Conventionally, in this type of hierarchical communication device status management system, as shown in the flow chart of FIG. 3, the upper communication device 1 updates the status of a subordinate middle communication device such as a failure or maintenance status. When the change is recognized, the middle-level communication device status data creation process (step S11) is performed, and the status data is sent to the status monitoring device 4 by the created status data transmission process (step S12). Next, lower communication device status data creation processing (step S13) is performed for all of the lower communication devices belonging to the middle communication device.
The created data is transmitted to the status monitoring device 4 by the status data transmission process (step S14). Finally, it is confirmed whether or not transmission processing has been performed for all lower devices (step S15),
If YES, transmission of status data from the upper communication device 1 to the status monitoring device 4 has been completed.

[0004]

In the conventional hierarchical communication device status management system, the upper communication device separately stores the status data of the middle communication device and the status data of all lower communication devices under the middle communication device. It was a method of sending to the status monitoring device. Therefore, when the status of the middle-level communication device is updated, there is a disadvantage that status data of all subordinate lower-level communication devices must be sent. Therefore, the host communication device has a disadvantage that a large amount of data is sent to the status monitoring device, and the processing speed is reduced, and in the worst case, the control is temporarily disabled due to an increase in the line usage rate.

[0005]

A status management system for a communication device according to the present invention comprises an upper communication device, a number of middle communication devices under the communication device, and a number of lower communication devices under the medium communication device. A status management system for transmitting status management information of a hierarchical communication device from the higher-level communication device to a status monitoring device, wherein when the status of the middle-level communication device is updated, the middle-level communication device The creation of status data of all lower-level communication devices under its control, it is determined whether or not it is necessary to change the update, and if there is no need to change, only the status information of the middle-level communication device is transmitted from the higher-level communication device to the status. Transmit to monitoring device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a flowchart showing the operation procedure of one embodiment of the present invention. FIG. 2 shows a status data format sent to the status monitor 4. The configuration of the layered communication device is the same as the configuration of the conventional example shown in FIG.

In FIG. 1, when the upper-level communication device recognizes a change in the status of the subordinate intermediate-level communication device, in step 1, the number of the intermediate-level communication device and the new status of the intermediate-level communication device are set. Next, in step 2, if it is necessary to change all the subordinate lower-level devices according to the status of the middle-level device, the process proceeds to Yes, and the status data of the lower-level communication device subordinate to the middle-level communication device whose status has changed in step 3 is transmitted. It is created based on the status of the middle-level communication device, and is set in the lower-level communication device group status section in the format shown in FIG. (For example, fixed data such as a failure in the lower level when the middle level is in the failure state and a maintenance state in the lower level if the middle level is in the maintenance state). If it is not necessary in step 3 to update the status of the subordinate devices, the process proceeds to No. In step 6, only the middle device in the data format shown in FIG. 2 is set, and in step 5, the data is transmitted to the status monitoring device. In step 4, it is determined whether or not the processing has been performed for all the lower communication devices under the middle rank.
If the number is not enough, proceed to No and set the status data of the next lower communication device. If the status data for the subordinate device has been created, the process proceeds to Yes, and the data is transmitted to the status monitoring device 4 in step 5.

That is, the difference between the present embodiment and the conventional system is that when the status of the subordinate device must be changed in response to the change of the status of the middle device, in the case of the conventional system, After transmitting the status data of the device, it is necessary to transmit the status data of the lower-level communication device for the number of devices, which places a load on the line. In this embodiment, when the status of the lower-level device changes, the status of all the lower-level devices is changed. Since a flow that does not create data is also provided, the number of transmissions can be reduced (once), and the load on the line can be reduced. In particular, when the middle-level device is in failure, the status of the subordinate device cannot be determined, and when the middle-level device is in failure, nothing can be done as a lower-level device, so that it is regarded as a failure and status data is created.

[0009]

As described above, according to the present invention, the status information of the middle communication device is updated in the hierarchical network system by improving the status information processing procedure from the upper communication device to the status monitoring device. In this case, only the processing of the middle communication device can be performed without performing the status processing of all lower communication devices under the middle communication device. Therefore, since the status data to be sent to the status monitoring device is sent once, there is an effect that the processing speed can be improved and the line utilization rate can be made more efficient.
