Abstract

PURPOSE:To use a public line from an optional non-protocol terminal equipment immediately after a line interrupt request from the non-protocol terminal equipment by releasing the connection between a communication processing unit and a public line with a line interrupt request from the non-protocol terminal equipment connecting to the public line. CONSTITUTION:This system is provided with a transmission means 121 in a communication processing unit 12 sending a text to a non-protocol terminal equipment 15 connecting to a public line 14 from a job program 111 in a host computer system 11, a reception means 122 in the communication processing unit 12 receiving a text from the non-protocol terminal equipment 15 connecting to the public line 14 to the host computer system 11 and a line interrupt means 123 in the communication processing unit 12 interrupting the line by a line interrupt command from the non-protocol terminal equipment 15. The line is available of use immediately by releasing the connection between the communication processing unit 12 and the public line 14 with the line interrupt request from the non-protocol terminal equipment 15 in this way thereby improving the line efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a non-procedural line control system, and more particularly to a non-procedural line control system for controlling a non-procedural terminal connected to a public line.

[Conventional technology]

In the conventional non-procedural line control method for non-procedural terminals connected to public lines, there is no way to notify the host computer system of a line disconnection request from the non-procedural terminal, so the public line is disconnected on the non-procedural terminal side. After that, the disconnected public line remains unusable until the line is disconnected due to non-communication monitoring by the communication processing device.

[Problem to be solved by the invention]

In the conventional non-procedural line control method for a non-procedural terminal connected to a public line, as described above, there is no means to communicate a line disconnection request from the non-procedural terminal to the host computer system. After the disconnection, the disconnected public line becomes unusable until the line is disconnected due to non-communication monitoring by the communication processing device.

[Means to solve the problem]

The non-procedural line control system of the present invention is a non-procedural line control system in which a business program in a host computer system performs data communication to a non-procedural terminal connected to a public line via a communication processing device. a transmitting means within the communication processing device for transmitting a message from a business program in the computer system to the nine non-procedural terminals connected to the public line; and a message from the non-procedural terminal connected to the public line to the host computer system. and a line disconnection means within the communication processing apparatus that disconnects the line in response to a line disconnection instruction from the non-procedural terminal.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of the non-procedural line control system of the present invention.

Referring to FIG. 1, this embodiment is comprised of a host computer system 11, a communication processing device 12, a communication path 13, a public line 14, and a non-procedural terminal 15. The host computer system 11 also has a business program 111.
The communication processing device 12 includes a transmitting means 121, a receiving means 122, and a line disconnecting means 123.

FIG. 2j is a flowchart showing the processing flow of the receiving means 122 of this embodiment.

As shown in FIG. 2, the receiving means 122 includes an upstream message analysis process 21, a line disconnection request notification process 22, and an upstream message communication process 23.

FIG. 3 is a flowchart showing the processing flow of the line disconnection means 123 of this embodiment.

The line disconnection means 123 includes a single line disconnection request reception process 31, a line disconnection process 32, and a line disconnection notification process 33, as shown in FIG.

Next, the operation of this embodiment will be explained with reference to the drawings.

The communication processing device 12 is coupled to the host computer system 11 via a communication path 13, and a non-procedural terminal 15 is connected to the communication processing device 12 via a public line 14.

It is assumed that a session is currently established between the business program 111 and the non-procedural terminal 15.

The uplink message from the non-procedural terminal 15 is notified to the receiving means 122, and in the upstream message analysis process 21 of the receiving means 122,
If a session is established between the business program 111 and the non-procedural terminal 15, all upstream messages are notified to the business program 111 as normal messages by the upstream message notification process 23.

It is assumed that the work has been completed and the session between the work program 111 and the terminal 15 has been released.

When the non-procedural terminal 15 releases the connection to the public line 14 without notifying the communication processing device 12, the communication processing device 12 issues a line disconnection request to the host computer system 11. Otherwise, it cannot be used from any non-procedural terminal via the public line 14 unless the connection to the public line 14 is once disconnected from the wireless communication monitoring function button of the communication processing device 12.

Therefore, the non-procedural terminal 15 requests the communication processing device 12 to disconnect the line.

When the communication processing device 12 receives the uplink message from the non-procedural terminal 15, it processes the business program 111 and the non-procedural terminal 1.
If no security connection has been established with 21.5, the uplink message analysis process 21. Line cutting In the line cutting means 123,
A line disconnection process 32 releases the connection to the public line 14, and a line disconnection notification process 33 notifies the host computer system 11 of disconnection.

In this way, in response to a line disconnection request from the non-procedural terminal 15, the line becomes usable immediately, especially when the connection between the communication processing device 12 and the public line 14 is released.

〔Effect of the invention〕

As explained above, the non-procedural line control method of the present invention is
A communication processing device connected to a host computer system via a communication path can disconnect from a non-protocol terminal by releasing the connection between the communication processing device and the public line in response to a line disconnection request from a non-protocol terminal connected to a public line. This has the advantage that it can be used immediately from any non-procedure terminal through the public line after a line disconnection request is made.
