。[Problem to be Solved by the Invention] In a system using a conventional procedure conversion device, the number of lines required on the information processing device side varies depending on the nature of the call on the terminal side, but the number of lines required for a specific information processing device depends on the time of day. When the number of terminals is concentrated, each information processing device needs to have a sufficient number to process requests from all terminals.

問題であった。For example, from 9:00 to 10:00, requests are concentrated on the information processing device 1, and the number of lines required for processing is n1.
From 11:00 to 13:00, requests are concentrated on information processing device 2, and the number of lines required for processing is n2, from 13:00 to 17:00.
Until then, requests were concentrated on the information processing device 3, and if the number of lines required for processing was n3, the number of lines required on the information processing device side was n1 + n2 + n3 (lines), which was a problem.There was a problem that there was a lot of waste. .

なるようにして構成される。[Means for Solving the Problems] A terminal connection procedure converting device of the present invention is capable of transmitting an error message between any one of two or more information processing devices and a terminal connected via an exchange. In a terminal connection procedure conversion device used in a system that sends and receives messages in a combined format, a message received immediately after connection with a terminal is used as an instruction for route selection to the terminal connection procedure conversion device, and the Decide which of the two or more information processing devices connected to the terminal connection procedure conversion device should be connected, and thereafter send messages received from the terminal to the information processing device until the connection with the terminal is terminated. Then, the message received from the information processing device is transmitted to the terminal, and information processing devices that are not selected are configured to have no data to send.

One is the mode from when a terminal connects until one message is received, and the flag value is 0. The other mode is the mode after receiving one message from the terminal, and the value of the flag is set to 1. When disconnecting the terminal, change the flag value to 0 and then turn off the power.

処理装置３を指定したメッセージとする。[0009] The first message after the terminal is connected is a message specifying which information processing device to send to, and there are three types as follows. That is, message 1 is a message that specifies information processing device 1, message 2 is a message that specifies information processing device 2, and message 3 is a message that specifies information processing device 3.

Further, if a message is received from the information processing device 2, this message is transmitted to the terminal 51. Furthermore, if a transmission invitation is received from an information processing device other than the information processing device 2, a response with no transmission data is returned.

い。Effects of the Invention As explained above, even when requests are concentrated on a specific information processing device depending on the time of day, the present invention does not require a line sufficient to process the requests for each information processing device, and can be applied at the time of greatest concentration. All you need is a line that can handle calls.

回線数削減の効果を有する。For example, from 9:00 to 10:00, requests are concentrated on the information processing device 1, which requires n1 lines for processing, and from 11:00 to 13:00, requests are concentrated on the information processing device 2. The number of lines required for processing is n2, and requests are concentrated on the information processing device 3 from 13:00 to 17:00, and the number of lines required for processing is n3, then the number of lines required on the information processing device side is n2. The largest value among n1, n2, n3 is sufficient,
This has the effect of reducing the number of lines.
