[Operation] FIG. 1 is a block diagram of a telegram control method converter of the present invention.

Reference numeral 1 is a message reception processing unit for receiving a message received from one of the connected communication networks. Reference numerals 1a, 1b, 1c ... Are provided for communication systems having different message flows. It is a message reception processing module. Each of the message reception processing modules 1a, 1b, 1c ... Of the message reception processing unit 1 checks the format of the received message, returns the message from its own system, counts the number of received messages, logs the received message, etc. Message reception processing is performed.

Reference numeral 3 is a message control matrix table for setting the processing method for the message received this time. The message control matrix table 3 is a type of message received this time (hereinafter referred to as a new received message) and a message transmitted to the other communication network immediately before the reception of the new received message in the communication path where the new received message is received. For each combination with the type (hereinafter referred to as the immediately preceding transmission sentence), it has information on the processing to be performed when the event occurs.

Reference numeral 4 is a communication route management table which is set for each communication route and stores control information of each communication route. In addition, the communication path management table 4 has an area for storing at least one electronic message last transmitted to the other communication network using the communication path for each communication path.

Reference numeral 5 is a message transmission processing unit which performs a transmission process for a message transferred to the other connected communication network. The electronic message transmission processing unit 5 is composed of a plurality of electronic message transmission processing modules 5a, 5b, 5c, ... Which carry out each processing corresponding to the processing information set in the electronic message control matrix table 3. .

Reference numeral 2 is a table analyzer processing unit for analyzing and determining the processing method for the electronic message received this time. First, the table analyzer processing unit 2 receives a new received sentence from one communication network from the electronic message receiving processing unit 1. Thereafter, the electronic message control matrix table 3 is searched from the type of the new received sentence and the type of the immediately preceding transmitted sentence stored and stored in the communication route management table 4 regarding the communication route that received the new received sentence, A message transmission processing module 5 that determines a process for the current state and corresponds to the process
The received message is passed to a, 5b, 5c ... And the processing is started.

The telegram control system converter of the present invention has the following features.

When a communication system having a different message control system is connected by the conventional method of transferring a message transmitted from each communication system to the communication system of the other party by pass-through, various methods may occur due to a difference in time-out value or the like. Failure of.

For example, it is as follows.

(1) The time out time from the request transmission of one connected communication system (referred to as communication system A) to the reception of a response is ta, and the same communication time of the other communication system (referred to as communication system B). Assuming that the time-out time for processing is tb and ta <tb, if the response sent from the communication system A side does not receive a response within the time ta, a cancellation message for the request is sent. On the other hand, in the communication system B, the time-out time has not yet been reached, and the cancellation telegram sent from the communication system A shows a reaction that an abnormal telegram has been received (see FIG. 2).

(2) Continuation of (1), (tb-ta)
When the communication system B finishes processing the request within the time and sends the response to the communication system A, the communication system A already cancels the request and waits for a response to the cancellation. It shows the reaction that an abnormal message is received in response to the response message (Fig. 3
reference).

On the other hand, in the present invention, by having an area for storing and storing the telegram transmitted immediately before by the gateway system, the state of the telegram control of each communication system can be recognized, and the telegram control matrix is also provided. The table allows the processing method of the gateway system in that state to be defined, enabling data communication of communication systems having different message control methods as described above (see FIG. 4).

That is, it becomes as follows.

The request from the communication system A to the communication system B is received, and it is recognized from the electronic message that the communication system A is requesting the communication system B for processing.

The cancellation telegram from the communication system A recognizes that the communication system A has timed out. However, since the telegram transmitted immediately before is the request telegram from the communication system A to the communication system B, the communication system B side knows that it is still processing. In the processing of the gateway system in that state, the contents of the transmission message area are changed from the table to the received cancellation message, and it is determined that the message is discarded.

From the response message from the communication system B, the communication system B recognizes that the processing for the request is completed. However, the telegram transmitted immediately before has been updated to the cancellation telegram from the communication system A.
Indicates that the request has been canceled. The process of the gateway system in that state recognizes that the cancellation telegram is transmitted to the communication system B from the table and the transmission telegram is stored in the transmission telegram area.

Upon receiving the cancellation report from the communication system B, the communication system B recognizes that the processing for the request has been canceled. On the other hand, the communication system A side also knows that the cancellation processing is being performed from the stored cancellation telegram, and transfers the cancellation report to the communication system A by pass-through.

As described above, in the gateway system, although the contents of the message transmitted / received between the communication systems A and B are not conscious (only the kind of message is conscious), the message transmitted immediately before is transmitted. Or, by only saving one message of the discarded message, the system recognizes the status of the message control of the communication systems A and B, and responds to it so that the program of the gateway system is easy to understand and the development man-hour is reduced. You can

Moreover, in the present invention, the judgment of the processing for the received electronic message depends on the table, and the program to be developed does not need those judgment units, and only the description of the processing method for each processing is necessary. , More effective.
