Abstract

PURPOSE:To evade a faulty processing at the maintenance operation control means by identifying automatically the presence of a corresponding response after the transmission of a command so as to synchronize communication of an electronic switching system with that of the maintenance operation control means. CONSTITUTION:A personal computer 2 identifies the type of a command in sending the command to an electronic switching system 1, stores a recognition code (reference command identifier CiD0) tentatively and compares a reference command identifier CiD0 with a command identifier CiD attached to the response in receiving the response from the electronic switching system 1 to apply detailed processing depending on the message identifier and the content of the response. In case of dissidence, till the response signal of the command signal is returned, the maintenance and operation processing corresponding to the said command is not applied. Thus, the communication between the electronic switching system 1 and the personal computer 2 is synchronized and abnormal processing by the content of message is evaded.

The purpose of this system is to automatically identify the response that corresponds to the command after it is sent, and to enable efficient maintenance and operation of the electronic switching system.

A reference command identifier corresponding to the command signal is stored in the maintenance operation control means when the command signal is sent, and upon receiving the command signal, a command corresponding to the command signal is sent from the electronic exchange system. When the response signal containing the identifier is received by the control means, the maintenance and operation control means compares the reference command identifier and the command identifier included in the response signal, and if the comparison results match. If so, the system is configured to allow execution of maintenance and operation processing based on the command signal.

[Example] The present invention will be described in detail below with reference to one drawing.

FIG. 2 is a block diagram showing one embodiment of the present invention.

In FIG. 2, 1 is an electronic switching system, and 2 is a personal computer constituting a maintenance operation control means. The personal computer 2 is externally connected to the electronic switching system 1 via a communication line.

In the case of this embodiment as well, the personal computer 2 sends a command signal to the electronic switching system 1 during maintenance and operation of the electronic switching system 1, and after the personal computer 2 receives a response signal corresponding to the command signal from the electronic switching system 1, , the maintenance operation process corresponding to the command signal is executed.

Then, before sending the command signal to the electronic exchange system 1, the personal computer 2 performs the following steps al, a2-1. a2-2. Processing a3 is performed.

Here, step a1 is a step of inputting a sending command through the keyboard, and step a2-1 is a step of finding and recognizing a reference command identifier CiD corresponding to the sending command from a conversion table held by the personal computer 2. Reference command identifier Ci
D is represented by three characters, for example rloOJ.

Further, step a2-2 is a step of storing the reference command identifier CiD recognized in step a2-1 in the storage area M1 of the memory in the personal computer 2;
Step a3 is a step of sending a command signal.

Next, before the electronic exchange system 1 sends the response signal to the personal computer 2, the next steps bl and b2 are performed on the electronic exchange system 1 side.

Here, step b1 is a step of receiving a command signal, and step b2 is a step of sending a response signal including a command identifier CiD corresponding to the command signal* a message identifier M i D indicating the contents of the message, processing contents, etc. In step, the command identifier CiD is
Three characters in the response signal are assigned, and one character is assigned to the message identifier MiD.

Note that the message identifier M i D indicates what the operational processing content that comes after this message identifier M i D in the response signal represents. For example, "1" is a title, "2" is a blank, r3J is the content.

"4" represents the end.

In addition, the personal computer 2 is connected to the electronic switching system 1.
After receiving the response signal corresponding to the command signal from , and before executing the maintenance operation process corresponding to the command signal, the following step a4-1. a4-2. a5. a
6-1. a6-2゜a6-3. The process a7 is performed.

Here, step a4-1 is a step of receiving a response signal, and step a4-2 is a step of receiving a command identifier Ci D of the response signal received in step a4-1.
In step a5, the reference command identifier CiD stored in the storage area M1 is stored in the storage area (response receiving area) M2 of the memory in the personal computer 2.

Step a6-1 is a step of comparing the command identifier CiD of the response reception area M2 with the message identifier CiD (title, blank, content, end).
Step a6-2 is a step of performing processing for each message identifier M i D. Step a6-3 is a step of determining whether it is finished. Step a7 is a step of determining whether the reference command identifier Ci Do and the command This is a step of performing another process (doing nothing or displaying a message to that effect on the monitor or printer) if the identifier CiD does not match.

With the above configuration, first, in step a1 of FIG. 1, when a send command is entered through the keyboard, in step a2-1, the reference command identifier CiD corresponding to the send command is found from the conversion table held by the personal computer 2. and take it out, step a2-2
, the reference command identifier Ci corresponding to the sending command
D, is stored in the storage area M1 of the personal computer 2, and then in step a3 a command signal is sent to the electronic switching system 1 through the communication line.

On the other hand, on the electronic exchange system 1 side, in step b1, the command signal is received, and in step b2, a response signal containing the command identifier CiD, message identifier M i D, processing details, etc. is sent to the personal computer 2 via the same communication line. Send via.

Next, on the personal computer 2 side, step a
When the response signal is received in step 4-1, step a4
-2, the command identifier Ci_D of the response signal received in step a4-1 is stored in the storage area (response receiving area) M2 of the memory within the personal computer 2. Next, in step a5, the reference command identifier CiD stored in the storage area M1 and the command identifier CiD in the response receiving area M2 are compared, and in step a6-1, the meaning (title, blank, etc.) of the message identifier MiD is compared. content, end) and step a6-2.
Then, processing is performed for each message identifier M i D. Then, in step a6-3, if the process is finished, the above process is finished.

On the other hand, if the reference command identifier CjD0 and the command identifier CiD do not match in step a5, step a5
In step 7, another process (receiving but not doing anything, or displaying a message to that effect on the monitor or printer) is performed, and the maintenance operation process corresponding to the command is performed until the response signal for this command signal is returned. will not be carried out.

In this way, when sending a command to the electronic exchange system 1, the command type is recognized, the recognition code (reference command identifier Ci D,) is stored for - hours, and when a response from the electronic exchange system 1 is received, , the reference command identifier CiD is compared with the command identifier CiD attached to the response, and it is determined whether it is a response to the forwarded command. If it is determined that it is, then the response message is further transmitted. While more detailed processing is performed depending on the identifier and content, if the reference command identifier CiD and the command identifier CiD do not match, separate processing (receiving but doing nothing, or displaying a message to that effect on the monitor or printer) Since the maintenance operation process corresponding to the command is not performed until the response signal for this command signal is sent back after the command signal has been executed, the communication between the electronic switching system 1 and the personal computer 2 can be synchronized, and the message Therefore, abnormal processing due to the contents of is avoided.

And especially when it comes to electronic exchange systems.

Since the usage rate, failure messages, etc. are output periodically or randomly, this is effective in avoiding abnormal processing on the personal computer 2 side.

Note that since the message identifier M i D also includes processing completion message information, step a6-3 is performed as follows.
This step a6-3 may be omitted since it can be performed simultaneously with the process of step a6-2.

Also, as shown in parentheses under step a4-2 in FIG. 1, only the command identifier CiD is included in the response signal, and the message identifier M
Even if the ID is omitted, the present invention can be implemented.

[Effects of the Invention] As detailed above, according to the command response identification method during maintenance and operation of the electronic exchange system of the present invention, after sending a command, it is automatically identified that the response corresponds to the command, and the electronic Since it is possible to synchronize communication between the exchange system and the maintenance operation control means, it is possible to easily handle abnormalities on the maintenance operation control means side, thereby reducing the maintenance and operation work of the electronic exchange system. It has the advantage of being able to do this efficiently.
