Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic response system for an I5DI composite terminal device.

[Conventional technology]

With conventional ISDN terminals, as described in Japanese Patent Application Laid-Open No. 61-109358, when a call arrives when the communication mode set on the terminal is automatic response mode, a message is immediately sent back to the other party's terminal. .

[Problem to be solved by the invention]

In the conventional technology described above, when a call setup message without subaddress information is received on a line where multiple ISDN terminals are connected to the same in-house bus and are set to the same communication mode and are automatically answered, the network The terminal that first sent the response message becomes able to communicate. However, in this case, there is a problem in that it is not possible to specify the terminal to be able to communicate on the bus within the premises. The object of the present invention is to provide a function that can prioritize the terminals that respond to the arrival of a call setup message without a subaddress on a line connected to the terminal.

[Means to solve the problem]

The above object is to provide a means for notifying the user of the current response priority, a means for the user to set the response priority, and a means for storing the response priority set by the user. This is achieved by providing a table for determining the timer value for sending a response message to the network after receiving an incoming call, and providing means for sending the response message after the timer value has elapsed.

[Effect]

The response priority is displayed on the display device, and when the automatic response mode is set, the response priority that is input by the user as 0 is stored on the storage device. In the table for determining the timer value, a short timer value is set in advance when the response priority is high, and a long timer value is set when the response priority is low.

When the automatic response mode is set, when a call setup message is received, the response priority is read into the storage device, and based on the response priority, a timer value for delaying response message transmission is determined from the above table. A timer is activated to send a response message after a timeout, and terminals with higher response priority will send response messages as soon as possible.As a result, terminals with higher response priority will respond to incoming calls in order. 0 [Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.〇 Fig. 1 is an example of a system configuration of an ISDN composite terminal according to an embodiment of the present invention. This system includes a processing device 100 that controls each system process, a storage device 110 that stores control tables, etc., a display device 120 that displays dial numbers, etc.
a line interface circuit 160 that controls the telephone line;
It has a data terminal interface circuit 140 that controls the data terminal.

FIG. 2 shows the structure of the response priority control table according to the present invention. The 0 response priority control table is as follows:
This is a rounding table that determines the timing of sending a response message according to the response priority.Response priority 210
and the corresponding response delay timer value 22G, and is held on the storage device 140. The larger the response priority 210, the higher the priority, and the lowest priority is set at system startup. Furthermore, when the automatic response mode is set, the response priority set at that time is displayed, and the user can change this value if necessary. Furthermore, if the user does not change the priority, the previously set priority will be used. Corresponding to response delay timer value 220 and response priority 210,
When the response priority 210 is high, a short timer value is used, and when the response priority 210 is low, a long timer value is used.

FIG. 3 shows the configuration of a program that operates on the processing device 110. The program includes a line input/output control process 300 that controls the line interface circuit 150, a call control process 320 that implements a line-switched call procedure, a data communication control process 320 that controls the data terminal interface circuit 160, and a telephone function control process. The telephone operation control processing 530 is configured to perform telephone operation control processing, a response priority control processing 310 to control automatic responses for each terminal, and a timer processing 350 to start and stop a timer.

FIG. 4 is a processing flowchart in the response priority control processing unit 640.The present invention will be explained in detail below using this diagram.

When receiving a call setup message, the line input/output control processing unit 600
The response priority control processing section 540 recognizes the incoming call via the call control processing section 510. Response priority control processing unit 6
In step 40, it is first determined whether or not the own terminal is set to automatic response mode (400).

If the automatic response mode is not set, the process here ends (410). If automatic response mode is set, the response priority set at that time is 21.
0 is read (420) and the corresponding response delay timer value 220 is determined from the response priority.

Next, in order to delay the sending time of the response message to the call setup message, the timer section (550) is started at the timeout time of the response delay timer value 220.
), it enters a timeout waiting state from the timer section (45
0) o When receiving a timeout notification from the timer section, the response priority control processing section 640 terminates the processing and passes the processing to the call control processing section 310 for sending a response message.

FIG. 5 shows an example of ISDN home path connection in an embodiment according to the present invention, in which terminal A300, terminal B520, and terminal C550 are in automatic response mode and are ISDN terminals and terminals in the same communication mode. D540 is in automatic response mode and has a different communication mode than the other three terminals.
It consists of a terminal and a digital exchange 510. Also, at this time, the response priority of terminal B 520 is set higher than that of terminal C.

FIG. 6 shows a sequence diagram of the incoming call between the terminals in FIG. , the call control processing section 61Ω, the response priority control processing section 640, and the timer section 650.

The incoming call sequence when response priorities are added will be explained below using FIGS. 5 and 6. When the terminal B 520 and the terminal C 530 simultaneously receive the call setting message from the terminal A 300, the line input/output control unit 300 notifies the call control unit 510 of the reception of the call setting message (600).
8). The call control unit 310 uses the call setting message to
The communication modes are compared and the sub-addresses are compared, and when the communication modes match and there is no destination sub-address, the response priority control unit 540 is notified of reception of the call setting message (601
) (609). The response priority control unit 340 starts the timer unit 350 (6o
2) (+510) 1. , it enters a timeout waiting state. The timer section 350 starts a timer for delaying response message sending, and when the timer stops, notifies the response priority control section 340 of timeout (605) (61
1). Response priority control unit 34 that received the timeout
0 notifies the call control unit 310 of the response message (6
o4) (612). At this time, terminal B 520, which has a higher response priority, times out earlier than terminal C 530, which has a lower response priority (606) (611), so terminal B 520, which sends the response message first, cannot start communication (607). Terminal C5 that sends a response message from
50 are released (,5+4).

As described above, according to this embodiment, when the automatic response mode is set, the interval between receiving a call and sending a response message can be adjusted using the response priority. When multiple units are connected,
Even if a call arrives without specifying a terminal on the line, it becomes possible to determine the order in which terminals will respond to the call.

〔Effect of the invention〕

According to the present invention, in an ISDN composite terminal device, when there are multiple terminals on the same communication mode and set to automatic response mode on the same in-home bus, the user can input a response priority order. This has the advantage that the receiving terminals can be ranked.
