Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a call termination schedule notification system for an automatic exchange.

(Prior Art) The conventional technology will be explained using the relay system diagram of an automatic exchange shown in FIG.

When the multifunction telephone 25 to be called is busy, the operator
Press the callback button 28 in the multifunction telephone 24,
Next, the user dials the telephone number of the multifunction telephone 25 that is currently on the call. This information is converted into a digit code 29 and sent via an interface 30 and a line circuit 26 to the central control bag@22. The central control unit 22 decodes this information, recognizes that the callback is to the multifunction telephone 25, and stores in the main storage device 23 the number of the telephone 25 necessary for the callback. The central control unit 22 monitors the multifunction telephone @25, and when the end of the call is confirmed, sends a ring tone to the multifunction telephone 24. When the operator of the multifunction telephone 24 answers this call, the multifunction telephone 2
A ring tone is also sent to 5.

When the operator of the multifunction telephone 25 answers, the switch 21
t-control to form a communication path between line circuits 26 and 27, allowing multifunction telephones 24 and 25 to communicate.

(Problems to be Solved by the Invention) In the above system, if the called party is busy, the calling party must call back and wait for the end of the call.

As a result, it was difficult to predict whether a callback would occur, which was inconvenient.

The purpose of the present invention is to
To provide a call termination schedule notification method that allows a called party to be notified of the scheduled call termination time by a display device.

(Means for Solving All the Problems) In order to achieve the above-mentioned object, the call termination schedule notification method of the automatic exchange according to the present invention has the following features:
In an exchange accommodating a multifunction telephone that supports a control signal channel independent of an information channel, the exchange further comprises: an input device for inputting a notification request for a call end time and an estimated call end time amount to the multifunction telephone; and a display device for displaying information from the caller, and if the caller encounters the called party talking after dialing the exchange, the caller terminates the call from the input device of the calling party's multifunction telephone. When control information requesting time notification is input, the calling party number is displayed on the display device of the called party's multifunction telephone, and in response, the called party exits from the input device of the called party's multifunction telephone. The present invention is constructed by providing a control means for controlling the display device of one caller's multifunction telephone to display the scheduled call end time when the scheduled time is input.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of a call termination schedule notification method according to the present invention.

The multifunction telephones 4.5 are of the same configuration, each connected to the switch 1 via a line circuit 6.7. The multifunction telephone 4 is connected to the line circuit 6 by the interface 10.
It is connected to the input device 9 and the display device f18'kN.

Similarly, the multifunction telephone 5 also has a display device 11. It has an input device 12 and an interface 13.

The line circuit 6.7, the switch lb and the main memory 3 are controlled by the central controller 20.

Here, the telephone numbers of multifunction telephones 4 and 5 are respectively 4100.4200.

t of the multi-function telephone 5 where the caller of the multi-function telephone 4 is talking
If you dial r& number 4200t.

The information is sent to the central control unit 2 through the line circuit 6t-valve.

The central control unit 2 clears this message and sends it to the multifunction telephone 5 via the caller's T track number 4100'i line circuit 7, and displays the caller's T track number 4100 on its display [11]. Number 4100
iDisplay. As a result, the called party of the multifunction phone a5,
It is possible to know that there is a request for a call termination schedule notification from the caller of the multi-function telephone 4.

FIG. 2(a) shows a state in which the calling party's telephone number is displayed on the multifunction telephone internal display device 11 of the called party during a telephone conversation.

After the called party on the multifunction telephone 5 confirms the displayed telephone number, he operates the input device 12t to input the call end time, and the information is sent to the central control device 2 via the line circuit 7. The central control device 2 receives a request to notify the caller of the call end time, and causes the display device 8 in the multifunction telephone 4 to display the call end time notified from the multifunction telephone 5.

FIG. 2(b) shows a state in which the scheduled call end time of the called party during the call is displayed on the caller's internal display device of the multifunction telephone.

If the call of the called party on the multi-function telephone 5 is completed by the displayed time, the operators of the multi-function telephones 4 and 5 are enabled to talk.

(Effects of the Invention) As explained above, the present invention is configured to be able to notify the caller of the expected time when the called party's call will end during a call. be.
