Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a network operation system comprising an operation center that maintains, operates, and manages a communication network, and an operation target that is maintained, operated, and managed by the operation center. Regarding.

[Conventional technology] There is a growing trend for conventional network operation systems to centrally maintain, operate, and manage the devices that make up the network at an operation center in order to save labor and speed up and accurately respond. Among them, for example, as shown in "Network Management System" in "Hitachi Hyoron" Vol. 69, No. 9 (September 1987), pages 61 to 69, various commands possessed by the operation target equipment and target system. There is a method in which operation information specific to the target equipment or system is posted to the operation center and the operation information is directly performed by the operation center, such as inputting information from a remote center or collecting various messages at the remote center. I was picking.

[Problems to be Solved by the Invention] The above-mentioned conventional technology has problems in controlling controllability of operation information such as command types and response types from the operation center when different target devices and target systems are managed by the same operation center. No consideration has been given to the controllability of the processing contents of operation information from the operation center, and when an operation is attempted at the operation center, the operation center has operation information corresponding to the target equipment and target system.
There is a problem in that the operation information from the target device or the target system must be reprocessed on the operation side depending on the processing content on the operation center side.

SUMMARY OF THE INVENTION An object of the present invention is to provide a network operation system in which the operation procedure and operation information transmission/reception interface on the operation center side can be controlled.

Another object of the present invention is to provide a means for smooth operation between an operation center having a single operation procedure and an interface for transmitting and receiving operation information, and target equipment/systems having operation information specific to the model or region. The objective is to provide a network operation system with

Still another object of the present invention is to provide a network operation system that can perform effective operations even when an operation center fails.

[Means for Solving the Problems] In order to achieve the above object, the network operation system according to the present invention provides a network operation system that allows an operation center to perform an operation on a target device/system that corresponds to operation information consisting of a single procedure.・Memorize and manage the correspondence of operation procedure signals of the target system,
An operation information/operation signal conversion/management section and an operation parameter change/management section are provided for converting between operation information and operation procedure signals.

In addition, in order to achieve other purposes, operation information specific to the target equipment/system is managed between the operation center and the target equipment/system, and information is sent and received between the operation center and the target equipment/system. An intermediate center is provided that has means for adding to and deleting operation information.

In addition, in order to achieve other objectives, in particular, as operating parameters, the operation information transmission from the target device/system to the upper operation center or intermediate center. I decided to keep it that way.

[Operation] In the above network operation system, the operation information/operation signal conversion/management section of the target device/system to be operated converts the unified operation information between the operation center and the target device/system into operational parameters. Since the signal is converted into an operation signal for the target device/system according to the operation parameters of the change/management unit, operations at the operation center can be executed in a single procedure.

Further, since the intermediate center between the operation center and the target device/system adds/deletes operation information specific to the target device/system, operations at the operation center can be easily performed in a single procedure.

In addition, as operating parameters, in particular, the actions to be taken in the event of an operational information error or alternative destinations are transferred to the target device/system in advance, so that even if the operation center or intermediate center becomes abnormal, the operating system will continue to operate normally. becomes possible.

[Example] Examples of the present invention will be described below with reference to FIGS. 1 to 7.

FIG. 1 is a block diagram showing an embodiment of a network operation system according to the present invention. This network operation system includes an operation center 10 that maintains, operates, and manages a communication network, and a target device or target system 100 to be operated, which is the target of maintenance, operation, and management of the operation center 10. ..., NO

The operation center IO communicates with target devices/target systems 100, . . . , N00 through communication path 1 and communication path interfaces 12, 120, . ..., N20
It has an operation information processing section 11 that processes, processes, and edits common operation information sent and received via the operation information according to the operation content. Target equipment/system 100 for operation. ..., N00 has a function of converting the common operation information sent and received with the operation center 10 into a signal for operating its own device or its own system, and manages the correspondence between the operation information and the operation signal. Operation information/operation signal conversion/management section 110°..., NIO,

In addition, there are man-machine interfaces (not shown) in the operation center 10 for instructing operation execution and displaying operation results.
0°..., there are devices (not shown) to be operated on in the NOO. Next, a typical operation example of the operation of the system shown in FIG. 1 will be explained. When an operation operation is executed from the operation center 10 to the target device/system 100 to be operated, in practice, for example, the bit error rate of a specific line is measured, or a failure detected in the target device/system 100 is measured. In some cases, we may notify detailed information regarding a specific device, or conduct continuity tests between terminals of specific equipment.

FIG. 2 is a flow chart of an example of the operation of the operation center 10 of FIG. When an operation execution command is input from the man-machine interface (not shown) for instructing the operation execution of the operation center 10 in FIG. The information processing unit 11 edits operation information according to the content of the operation,
The operation information is sent to the communication path 1 via the communication path interface 12 as an operation request signal 14
4. When the operation request signal is received by the target device/target system 100, a response signal is sent back via the communication path 1. In step A2, when the response signal is received, the response signal is confirmed, and the operation result signal that is returned following the response signal is received as operation information, and after the reception is completed, the received signal is transferred to the target device.
Send it to the target system 100. Thereafter, in step 83, the operation center 10 processes the operation information of the operation result signal according to the content of the operation, and sends an operation result signal etc. to the man-machine interface. As described above, in the operation center 10, the operation information that has been standardized based on the flowchart of FIG.・
..., all you have to do is send/receive it to/from NOO. Target equipment/target system 100. ..., NOO differences are handled as follows: Target device/target system 100. ..., NOO
Do it on the side.

FIG. 3 is a flowchart of an example of the operation of the target device/target system 100 shown in FIG. When the common operation request signal (step Al) sent from the operation center 10 is received as operation information in step B1, it is determined whether the operation request signal is a request signal for the own device or the own system, If it is a request signal to its own device/system, it transitions to the next state. In step B2, a response signal is sent back.

In step B3, operation information, operation signal conversion,
The management unit 110 converts the shared operation information into an operation signal for its own device/system. In addition, if there are operating parameters for operating the own device/system, in the first step B4, the operating parameter management unit 111 is referred to to determine whether or not the operating parameters need to be changed, and if a change is necessary. In step B5, the operation parameters are changed, and then in step B6, the operation execution control unit 112 executes the operation and collects and edits the operation results.

Furthermore, in step B7, the operation information/motion signal conversion/management section 110 converts the operation result into operation information.

After that, in step B8, the operation information is sent to the communication path 1 as an operation result signal, and in the next step B9, when a reception signal from the operation center 10 is received, the reception signal is confirmed and the target equipment/system 100 side Finish the operation.

Target equipment/system 1 for the above operations
00. . . . As a more specific example of the operation of the NOO, for example, after receiving the shared operation information "Measure the bit error rate of the designated line" from the operation center 10, ``Status confirmation'', ``Specified line and bit error rate measuring device bus settings'', ``Sending out r8++1 regular pattern'', ``Receiving measurement pattern''.

After converting into a series of operation signals called "calculation of measurement results" and determining whether or not it is necessary to change the "measurement time" specified as an operation parameter, execute the bit error rate measurement of the specified line,
There is a case where the measurement result is returned as an operation result signal of "bit error rate 10" 11IJ. By providing the operation information/operation signal conversion/management unit 110 and the operation parameter management unit 111 in the target device/system 100 as described above, transmission and reception between the operation center 10 and the target device/system 100 is made common. For example, "
All you need to do is to measure the bit error rate of the specified line and the measurement time, and the operation on the operation center 10 side will depend on the target equipment and the measurement time.
Since it is no longer affected by the target system 100, etc., and the amount of information transferred between the operation center 10 and the target equipment/target system 100, etc. can be reduced compared to the case where operation signals are directly transmitted and received. The line occupancy rate is also reduced, allowing efficient use of network resources. Furthermore, since the above-mentioned operation information and especially the operating parameters that are likely to change frequently are transferred via the communication path 1, there is no need for a worker to go to the installation location of the target equipment or target system 100, etc. to replace the data. This makes it possible to improve work efficiency and save labor.

FIG. 4 is a block diagram showing another embodiment of the network operation system according to the present invention.

This network operation system includes an operation center IO shown in FIG. 1, and a target device/system 100 to be operated. ..., MOO.

By providing a self-management device/system-specific information management/addition unit 21゜31 with a function to add/delete information specific to the target device/target system aggregated by 0, the operations at the operation center 10 can be further unified. This is an example that can be easily realized. Then the fourth
The operation of the system shown in the figure will be explained using a specific example of operation. The target device/target system 100 to be operated from the operation center 10. . . . When the NOO is caused to perform an operation, there is, for example, an operation to restore the CPU usage rate from among the digital exchanges that constitute the network.

FIG. 5 is a flow chart of an example of the operation of the intermediate center 20 (30) of FIG. Target equipment/system 1 above
00t..., MOO(M, 10G,..., N0
For example, when performing an operation such as O) to restore the CPU usage rate from among the digital exchanges that make up the network, the operation center 10 uses the standardized operation information shown in the flowchart in FIG. It is sent to communication path 1 as a request signal (step Al). However, in this case, all target devices/target systems 100. ..., NOO
There is no need to send the operation request signal to the intermediate center 20, 30 instead. The intermediate center 20.30 receives the operation request signal from the operation center 10 as operation information in step C1 of the flowchart of FIG. 5, and determines whether the operation request signal is a request signal to its own management device/system. For example, the intermediate center 20 is the target device/target system 100. ..., in the case of an intermediate center that manages a digital exchange of MOO, when the intermediate center 20 receives an operation request signal for restoring the CPU usage rate of the digital exchange, the intermediate center 20 controls its own management device.
After determining that it is a request signal to the system, step C
At step 2, a response signal is sent back to the operation center 10.

Next, in step C3, the self-managed device/system specific information management/addition unit 21 applies the received operation information to the self-managed target device/target system 100. ...MO
Adds additional information specific to O. For example, for A station, the digital exchange of A station is under construction, so rcpu
The operation information "Measure and transfer usage rate" is determined to be "not transferred", and for station B, the rCPU is used because unit C of the three digital exchanges a, b, and C is out of order. Measure and transmit the rate.”
For example, additional information such as ``C unit and B unit'' may be added to the operating information. After adding the unique additional information in this way, in step C4, the operation information is used as an operation request signal to the target device/target system 100. ..., transfer to the MOO target digital exchange.

Figure 6 shows the intermediate center 20 (30) in Figure 4 following Figure 5.
2 is a flowchart of an example of the operation. The above operation request signal (step C4) is sent to the target device/target system 1.
00. . . . When the target digital exchange of MOO receives the data, for example, C
After measuring the PU usage rate and converting the measurement result into operation information, it is then sent back to the intermediate center 20 as an operation result signal (step B8).The intermediate center 20 receives the operation result signal in step D1 of FIG. After receiving the information as operation information, the self-management device/
It is determined whether the result is from the system, and if the result is from the self-management device/system, in step D3, the self-management device/system-specific information management/addition unit 21 selects the target device or target from the received operation information. Additional information specific to the system is deleted and edited to information that matches the operation request signal from the operation center 10. For example, when deleting unique additional information, such as the CPU usage rate, the result returned from station B is
The additional information "of unit" and "b unit" are deleted. Next, in step D4, the operation information is transferred to the operation center as an operation result signal, and thereafter, as in FIG. 3 (step B9), when the intermediate center 20 receives the received signal from the operation center 10, it receives the received signal. Confirm and finish the process. As described above, according to this embodiment, the operation center 10 operates all the target devices/systems 100. ..., there is no need to manage operation information regarding N00, the configuration of the operation center 10 is simplified, and the operation center 10 and all target devices/systems 100°...N
It is not necessary to send and receive operation information to and from the OO, and the operation center 10 is connected to the intermediate center 20.
It is only necessary to send and receive operation information to and from 30, making it possible to effectively use the first-class communication channel resources.

FIG. 7 is another flowchart of an example of the operation when the operation center 10 or intermediate center 20, 30 of the target equipment/system 100 to NOO shown in FIG. 1 or 4 is abnormal. Target device/system 100 for this operation. . . , the flowchart of NOO includes operation information, especially target equipment/target system 100 . By transferring information that defines the operation of the NOO in advance, the operation system can operate normally even in the event of an abnormality in the operation center 1o or the intermediate centers 20, 30. For example, when information specifying an alternative transfer destination of operation information is given as information specifying the operation of the operation center 10 or the intermediate center 20.30 in the event of an abnormality, the target device/system 100. ..., NOO first steps B8
After transmitting the operation information as an operation result signal in (Fig. 3), in step E1, the reception monitoring state of the received signal is entered, and it is determined whether or not the received signal has been received, and if the signal is not received, In step E2, the operation parameter management unit 111 is referred to to determine the destination for retransmitting the operation information when the received signal is not received.
In step 3, the operation information is sent to the alternative transfer destination as an operation result signal. Thereafter, in step E4, as in FIG. 3 (step B9), when a received signal from the alternative transfer destination is received, the received signal is confirmed and the process is terminated. As described above, according to this embodiment, even in the event of an abnormality in the operation center 1o or intermediate center 20.30, the target equipment/target system 1 to be operated is
00. . . . Since N00 has operational information at the time of abnormality of the operation center 10 or the intermediate center 20.30, it is possible to continue normal operation as an operation system. For example, it is possible to continue normal operation as an operation system. If so, it is possible to prevent the operation result signal from being lost in the event of an abnormality in the operation center 10 or the intermediate center 20 or 30, and to reduce the number of operation result signal storage means on the operation target side.

[Effects of the Invention] According to the present invention, since the operation procedure of the operation center of the network operation system and the operation information transmission/reception interface between the operation center and the operation target can be unified, the operation center configuration can be simplified and This has the effect of making it possible to flexibly change and expand the functions of the operation center and operation targets.

Furthermore, since information specific to the operation object can be added or deleted at the intermediate center, there is an effect that the operation center does not need to manage all the operation objects.

Furthermore, since the operation target has operational information when the operation center or intermediate center is abnormal, there is an effect that the normal operation of the operation system can be continued even when the operation center or intermediate center is abnormal.
