Abstract

PURPOSE:To prevent useless health checking by executing the health checking while communication is not executed at the section of an exchange processor, and executing the health checking in a communication procedure at the section of the exchange procedure. CONSTITUTION:In a health check processing, selecting and the response reception of the selecting are used, a man-machine interface device 20 executes the selecting before a signal transmission, and an other exchange processor 30 returns the response to the selecting, the man-machine interface device 20 receives the response to the selecting, and thus, the health check processing is completed. That is, the health checking is completed by executing the selecting, receiving the response and returning a completion. Thus, since the health checking is not executed while the command is transmitted and returned and an alarm is received, namely the communication is executed, the useless health checking can be avoided.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a health check method, and particularly to a health check method in a switching system configured of a switching processing device and a device having a man-machine interface function for switching processing. Regarding.

[Conventional technology]

In this type of exchange system, a health check is employed as a means for checking the operation of the exchange processing device.

Conventionally, this health check has been performed using health check signals, and a system has been adopted in which a device with a man-machine interface function with the exchange processing device transmits such health check signals at regular intervals. .

[Problem to be solved by the invention]

However, in the past, a device with a man-machine interface function with a switching processing device always sent health check signals at regular intervals even under high load. Since the health check signal was being sent even though the exchange processing device was receiving the Another drawback is that the health check during high loads amplifies the load.

In other words, the above-mentioned conventional technology has the disadvantage that a health check is performed, which is a wasteful process even though it is known that the exchange processing device is operating by receiving a command signal or an alarm signal. Also, since health checks are performed even under high load, the load is amplified.

In particular, when there are two or more target exchange processing devices, it is necessary to respond to high loads due to the occurrence of a large number of alarms. If this happens, there is a great possibility that an appropriate response to the above situation will not be taken.

SUMMARY OF THE INVENTION An object of the present invention is to provide a health check method that can perform a health check on a switching processing device while preventing unnecessary health checks and eliminating load amplification caused by conventional health checks during high loads. It is in.

[Means to solve the problem]

The present invention provides a switching system including a switching processing device and a device having a man-machine interface function with the switching processing device, in which a device having a health check method man-machine interface function communicates with the switching processing device. It is characterized in that a health check is performed when there is no communication between the two, and that the health check is performed during the communication procedure with the exchange processing device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, and is an example of a system configured with two exchange processing devices and a man-machine interface device.

Further, FIG. 2 is a sequence diagram of an example of a communication procedure performed between an exchange processing device and a man-machine interface device, and FIG. 3 is a sequence diagram of an example of a health check.

As shown in FIG. 1, this exchange system includes two exchange processing devices (CP 1 and CP2) 30, a man-machine interface device (MMI) 20 as a device with a man-machine interface function, and a maintenance terminal (TTY). )10
It is composed of:

The man-machine interface device 20 is connected to the maintenance terminal 10 and to each exchange processing device 30, and has a man-machine interface function with exchange processing.

Regarding health check processing, the man-machine interface device 2c does not use a separate health check signal as in the conventional method, and therefore adopts a method of transmitting a special health check signal at regular intervals. There is no man-machine interface device 20.
performs a health check on the exchange processing device 30 when it is not communicating with the exchange processing device 30, and the execution of the health check is performed during the communication procedure with the exchange processing device 30. It is designed to do this.

As described above, the health check method according to the present invention provides a man-machine interface as a device having a man-machine interface function in an exchange system configured of an exchange processing device 30 and a device having a man-machine interface function between the exchange processing device 30. The device 20 is the exchange processing device 3
0, the problems of the conventional method are solved by performing a health check only when there is no communication with the exchange processing device 30, and by performing a health check during the communication procedure with the exchange processing device 30. While doing so, we are also making it possible to perform health checks.

For this reason, in this embodiment, in an exchange system including an exchange processing apparatus 30 and a man-machine interface apparatus 20 having a man-machine interface function with the exchange process, the man-machine interface apparatus 20 monitors the communication state with the exchange process. and the man-machine interface device 20 performs selection prior to signal transmission, and the exchange processing device 30 returns a response to the selection; The man-machine interface device 20 has means for completing the health check process upon receiving the response to the selection.

A detailed explanation will be given below with reference to FIGS. 2 and 3.

The man-machine interface shown in Figure 2! 20 and the exchange processing device 30 in the communication procedure shown in FIG. 2(a).
2(b) shows a case where a signal is transmitted from the man-machine interface device 20 side, and FIG.
This is the case for the transmission of signals from the side.

For commands, command responses, and alarms (for the K transmission, selection is performed prior to signal transmission (
(■) in Figure 2), a selection response (■ in Figure 2) from the other device (exchange processing device 30 in the case of Figure 2 (a), man-machine interface device 20 in the case of Figure 2 (b))
), then send the signal (■ in Figure 2), and after receiving completion of reception (■ in Figure 2) from the other device, return completion (■ in Figure 2), indicating that the signal transmission is complete. Become.

In the health check process, the man-machine interface device 20 performs selection prior to signal transmission, using the above-described selection and reception of a response to the selection, and the partner exchange processing device 30 responds to the selection. The health check process is completed when the man-machine interface device 20 receives the response to the selection. In other words, the health check is not sent as a signal, but is performed by selecting as shown in Figure 3.
Upon receiving the response and returning completion, the process is complete.

Further, when the health check timing comes during the sequence shown in FIG. 2, the health check is not performed. In other words, in the conventional method, even though command responses and alarm signals are received from the exchange processing device,
In other words, even though it is known that the exchange processing device is operating, it causes a situation where a health check is performed, which is a wasteful process. Command response.

Since a health check is not performed while an alarm is being received, that is, while communication is being performed, unnecessary health checks can also be avoided.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to not perform a health check while transmitting a command, responding to a command, or receiving an alarm, and it is possible to prevent the health check from being performed while receiving a command, a command response, or an alarm. Since the health check can be completed at , there is an effect that unnecessary health checks are not performed, and there is also an effect that the load is not amplified by the health check even when the load is high due to the occurrence of a large number of alarms.
