And a keyboard input control unit 103 for providing the session control unit with a timer 104a, which is a time counting unit that updates the elapsed time during which the session control unit 102 continuously establishes the session each time the session is established, The arrival of data from the host device and the input state of data to the keyboard input control unit 103 are monitored, and when the time measuring means measures the preset time, there is no data from the host device and data is input from the keyboard 106. When the state that there is no input is detected, the line control unit 101 is instructed to disconnect the public line. And a line disconnection control section 104..

Next, the operation of the above system will be described with reference to the drawings.

FIG. 13 is a diagram for explaining the operation of the conventional system.

Specifically, when the effective time which is the characteristic of the conventional system is not transmitted / received, when the time preset by the time measuring means is timed, there is no arrival of data from the host device and the keyboard. FIG. 6 is a diagram when a public line disconnection command is given to the line control unit to disconnect the public line when a state where there is no input from is detected.

In FIG. 12 and FIG. 13, when the user of the terminal does not perform the operation of transmitting the logoff command for ending the session with the host device,
Since the session control unit 102 does not receive data from the host device and does not accept input from the keyboard 106, the timer 104a of the line disconnection control unit 104 continues counting down. When the timer 104a becomes “0”, the line disconnection control unit 104 requests the session control unit 102 to transmit a logoff command. Session control unit 1
02 generates a logoff command, transmits it to the host device, and when receiving a session end command from the host device, notifies the line disconnection control unit 104 that the session has ended. When the line disconnection command is received after the session ends, the line control unit 101 turns off the ER signal of the modem 105 and notifies the line disconnection control unit 104 that the line has been disconnected.

[0011]

In the above-mentioned conventional system, when the terminal user connects to the computer and leaves the terminal to start another work in the middle of performing the work, the computer will be operated at the preset time. However, when the terminal user finished the other work and tried to use the computer from the terminal, there was a problem that the connection with the computer was cut off and the work could not be performed.

This operation will be described separately as "connection request" and "job start request" with reference to the drawings.

FIG. 4 shows the operation when a "connection request" is sent from the terminal 90 to the computer 10.

When a connection request is sent from the terminal 90 to the computer 10, the connection terminal monitoring means 20 receives a notification of the terminal name from the communication controller 80. Upon receiving the notification, the connected terminal monitoring means 20 registers the terminal name of the terminal 90 in the session management table 50 by the table registration means 30. At this time, the table registration means 30 sends the warning time to the terminal name of the terminal 90 based on the current time obtained by the current time acquisition means 40 and the maximum non-communication interval stored in the program data area 11 (current time + maximum no time). The communication interval) is calculated and registered in the session management table 50.

In this embodiment, the terminal name is TERM01 and the time when the terminal and the computer are connected is 00:00.

FIG. 5 shows the operation when a “job start request” is sent from the terminal 90 to the computer 10, and FIG.
Indicates the operation of the computer 10 at the end of the job.

In FIGS. 5 and 6, when a “job start request” is received from the terminal 90 to the computer 10, the job monitoring means 70 receives a “job start” notification from the communication control unit 80, and a “terminal name” is displayed. The job of (TERM01) is being executed ”. The connection terminal monitoring means 20 that has received the notification is the table registration means 30.
Then, the value indicating that the warning time is invalid is registered at the warning transmission time of the terminal name (TERM01) registered in the session management table 50.

When the job is completed, the job monitoring means 7
0 means "the job of the terminal name (TERM01) has finished"
To the connection terminal monitoring means 20. Upon receiving the notification, the connected terminal monitoring unit 20 receives the terminal name (TE) registered in the session management table 50 by the table registration unit 30.

Current time obtained by 0 and program data area 1
The warning transmission time (current time + maximum non-communication interval) is calculated from the maximum non-communication interval stored in 1 and updated.

In this embodiment, the terminal 90 (TERM01)
Requests the computer 10 to execute the job at 00:03, and the job ends at 00:10.

(Step 3): <Monitoring of connected terminal> In step 3, the connected terminal monitoring means 20 monitors the connected terminal. This operation will be described with reference to FIG.

The present time obtained by the present time acquisition means 40 and the warning transmission time to the terminal name of the session management table 50 are expressed by conditional expression 1 (whether the warning transmission time shows a valid value) and conditional expression 2 ( Check if there is a terminal whose warning transmission time has passed). During the comparison, the "warning is not transmitted" and the "warning is transmitted" can be found. An example of the "warning is not transmitted" will be described as a pattern with reference to FIGS.

Pattern: The terminal 90 connected to the computer 10 does not exceed the maximum non-communication interval determined by the administrator by the terminal user (the warning transmission time has not passed).

Pattern: A terminal 90 connected to the computer 10 issues a job execution request to the computer 10 and when this job is being executed on the computer 10 (a value indicating that the warning transmission time is invalid is shown. ).

In the example of the pattern, the terminal 90 is 00:00.
After connecting to computer 10 at 0, the current time is 00:
A case where the operation comes to step 3 as 05 will be described.

The connected terminal monitoring means 20 sets the warning transmission time (00:10) to the terminal name (TERM01) in the session management table 50 and the current time (00:05) obtained by the current time acquisition means 40. By comparison, it is recognized that the warning transmission time does not exceed the current time, so no warning is transmitted.

In the example of the pattern, the terminal 90 is 00:00.
After connecting to the computer 10 at 0, the execution of the job is requested at (00:03), the job is being executed, and the current time is 00:05, and the process will come to step 3.

The terminal 90 connected to the computer 10
When a job execution request is issued to the computer 10, invalid is registered as the warning transmission time to the terminal name (TERM01) in the session management table 50 in step 2. Therefore, while this job is being executed on the computer 10, the connected terminal monitoring means 20 recognizes that the warning transmission time to the terminal name (TERM01) in the session management table 50 is not a valid value, and the warning is not issued.

Next, an example of the "warning transmission pattern" will be described as a pattern with reference to FIGS.

Pattern: A terminal connected to a computer is in a non-communication state (a job execution request is not issued) over the maximum non-communication interval determined by the administrator.

Pattern: In the non-communication state, the maximum non-communication interval is exceeded after the pattern job is completed.

In the example of the pattern, the terminal 90 is 00:00.
The case where the current time is 00:11 and the operation comes to step 3 in the non-communication state after connecting to the computer 10 at 0 will be described.

The connected terminal monitoring means 20 compares the warning transmission time (00:10) to the terminal name (TERM01) in the session management table 50 with the current time (00:11) obtained by the current time acquisition means 40. However, it is recognized that the warning sending time exceeds the present time, and the warning sending means 6
When 0, the terminal name is notified to the communication control unit 80 and a warning is issued to the terminal 90.

In the example of the pattern, the terminal 90 is 00:00.
After connecting to the computer 10 at 0, the execution of the job is requested at (00:03), and the job is completed at 00:10. After that, when the current time is 00:21 and the process comes to step 3 in a non-communication state between the terminal 90 and the computer 10, it will be described.

The warning transmission time (00:20) to the terminal name (TERM01) in the session management table 50 by the connection terminal monitoring means 20 is compared with the current time (00:21) obtained by the current time acquisition means 40. However, it is recognized that the warning sending time exceeds the present time, and the warning sending means 6
When 0, the terminal name is notified to the communication control unit 80 and a warning is issued to the terminal 90.
