DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for restoring exchange data when exchange data is destroyed in a system in which data registration in an exchange is transmitted from a computer system through a line.

[Conventional technology]

In the conventional recovery method for exchange data, when exchange data is destroyed, data is manually extracted for recovery based on transmission and reception information that has been automatically collected in advance. - We are re-registering the exchange data one by one.

[Problem that the invention sought to solve]

The conventional exchange data recovery method described above requires a large amount of manual work, and requires a great deal of effort and time to recover a large amount of data.

SUMMARY OF THE INVENTION An object of the present invention is to provide an exchange data recovery method that allows data recovery to be performed in a relatively short time without requiring a great deal of effort.

[Means to solve the problem]

In the exchange data recovery method according to the present invention, there is a transmission/reception information successive unit that reads transmission/reception information into a total of one system, a retransmission message creation unit that creates a retransmission message based on the transmission/reception information, and a retransmission message generation unit that creates a retransmission message based on the transmission/reception information. A retransmission message transmission unit that sends to the exchange system and an extraction condition input unit that inputs the conditions for extracting the transmitted and received information are provided, so that when exchange data is destroyed, recovery information is quickly extracted and created, and the exchange This means that it will be retransmitted to the system.

〔Example〕

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

FIG. 1 is a block diagram of a system according to an embodiment of the present invention. The input device 11 inputs extraction conditions for recovering exchange data to the extraction condition input section 12.

The extraction condition input section 12 transfers the extracted extraction conditions to the transmission/reception information reading section 13.The transmission/reception information reading section 13 transfers the extracted extraction conditions to the external storage device 14 which stores all the transmission/reception information thus far.
The necessary transmission/reception information is extracted based on the extraction conditions given by .

The extracted transmission/reception information is created into a telegram to be transmitted to the exchange system 19 by the retransmission telegram creation section 15.

The retransmission message creation section 15 passes the created retransmission message to the retransmission message transmission section 16.

The retransmission message transmitter 16 is connected to the exchange system 19 through a line, and retransmits the retransmission message to the exchange system 19, receives the retransmission result from the exchange system 19, and retransmits the retransmission result. The message is returned to the message creation section 15.

The retransmission message creation unit 15 outputs the previously created retransmission message and the retransmission result to the output device 17.

In this way, the extraction condition input section 12 is connected to the computer system 18.
, a transmission/reception information reading section 13, a retransmission message creation section 15, and a retransmission message transmission section 16 are provided to automatically recover exchange data.

Next, the contents of the exchange data recovery operation will be explained with reference to a processing flowchart of an embodiment in FIG. 2.

The processing flow shown in the processing flowchart of FIG. 2 can be executed in one or both of two ways: periodically or in the event of a fault in the exchange.

Further, each of the processing flows of the start of this processing flowchart, exchange data destruction 21, and exchange data backup 22 can be executed by either the computer system or the exchange system depending on how the system is constructed.

Here, the exchange data backup 22 stores data in a storage medium for a period determined by the system in preparation for a serious failure such as a system down (for example, 1
Dump the data up to that point every day at midnight) and load the saved data to recover the system in the event of a failure. However, depending on the degree of failure, this exchange data backup 22 may not be performed.

Here, the data storage medium for backing up exchange data is located in either the computer system or the exchange system, depending on how the system is constructed.

Next, a series of processing flows will be explained. There was a problem with the exchange system and the system went down.

The exchange system runs various failure search and recovery processing programs in order to search for the cause of the failure and restore it, one of which is the processing flow shown in FIG. 2 for exchange data recovery.

First, the presence or absence of exchange data destruction is determined by the exchange data destruction presence 21 of the branch process, and if there is no exchange data destruction, the program directly goes to the end and executes another failure search and recovery processing program or performs another process.

If yes, switchboard data backup 22 for the next process.
Execute. As in the previous example, the data in this exchange data backup was saved at 24:00 midnight of the previous day, so in order to have the data closest to the time when the system went down due to data destruction, it is necessary to start from 24:00 midnight of the previous day. All you have to do is add the data up to the time the system went down to the exchange data backup data.

Therefore, the exchange system passes the line to the computer system to execute the data recovery extraction condition 23 of the process,
Sends information that data from 24:00 on the previous day until the system went down will be retransmitted. There is also a method of manually inputting the data recovery extraction condition input 23 from the input device 11 instead of automatically.

The computer system uses the extraction conditions received by this data recovery extraction condition input 23 to process the necessary information on the data from 24:00 on the previous day until the system went down, based on the transmitted information stored in the external storage device 14. It is extracted in the transmission/reception information extraction 24.

A message to be retransmitted to the exchange system 19 is created from the extracted transmission information in a retransmission message creation step 25 of the process.

The created retransmission messages are retransmitted all at once to the exchange system 19 in a batch retransmission 26 to the processing exchange system, and the retransmission results are received from the exchange system 19.

Finally, the retransmission message and the retransmission result are sent to the output device 17. The retransmission message and the retransmission result are printed out 27.
Exchange system 1 by printing out
9 data recovery work is completed.

〔Effect of the invention〕

As explained above, in the case of data destruction in a switching system, the present invention reads transmission/reception information to the switching system that is automatically collected in advance by a computer system based on extraction conditions, and creates a retransmission message. Batch retransmission has the effect that data recovery in the exchange system can be performed automatically.
