Abstract

PURPOSE:To display a total call charge while and after speaking in a key telephone system on an call incoming side. CONSTITUTION:When a call incomes from a public line to a trunk line interface 14, CPU 15 makes the call to income to a telephone set 13 with a display through a telephone set interface 12 and makes a calling side telephone number storage part 17 to store a telephone numbers on a calling side, which is sent from the public line, at the same time. CPU 15 makes a call charge calculation part 19 to calculate the call charge from the start of speaking to now by referring to area charge information stored in an area charge information storage part 18 and using its own telephone number which is previously registered in a self telephone number storage part 16 and the calling side telephone number stored in the calling side telephone number storage part 17. The total call charge is sent to the telehone set 13 with the display by way of the telephone set interface 12 at each unit time by the control of CPU 15 and displayed on the not-illustrated display of the telephone set 13 with the display.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone device for displaying a total call charge during or after a call on a key telephone on the receiving side.

[0002]

2. Description of the Related Art FIG. 2 shows a schematic configuration of a conventional key telephone device. In FIG. 2, this example shows a main device 1 connected to a public line and a telephone 3 connected to the main device 1.
And have. The main device 1 has a telephone interface 2 connected to the telephone 3, a station line interface 4 connected to a public line, a central processing unit 5 for controlling the telephone interface 2 and the station line interface 4.

Next, the operation of this conventional configuration will be described. When a call is received from the public line to the office line interface 4, the central processing unit 5 causes the telephone 3 to receive the call through the telephone interface 2.

As described above, even a conventional key telephone device can receive a call from a caller and can make a call.

[0005]

However, the button telephone device of the above-mentioned conventional example has a drawback in that the call charge of a call received on the receiving side cannot be known.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide an excellent button telephone device capable of displaying a total call charge during a call or after a call on a key telephone on the receiving side.

[0007]

In order to achieve this object, the key telephone device of the present invention is notified by a storage means for storing charge information for each area corresponding to a telephone number and a telephone number of a calling side. The telephone number of the calling side that identifies the telephone number of the calling side when a call is received from the line, the call time counting means that counts the call time from the start of the call, and the telephone number identification means of the calling side identify The unit call time charge of the incoming call is obtained from the calling party's telephone number, its own telephone number, and the regional charge information stored in the storage means, and the current call is made from this unit call time fee and the call time counted by the call time counting means. It is configured to include a call charge calculation means for calculating a charge and a call charge display means for displaying the call charge calculated by the call charge calculation means on the screen during and after the call.

In addition to this configuration, a call charge voice output means for displaying the call charge during and after the call on the call charge display means as an image and selectively outputting voice by voice synthesis is provided.

[0009]

In the button telephone device of the present invention having such a configuration, the unit call time charge of the incoming call is obtained from the identified calling side telephone number, the own telephone number, and the stored charge information for each area, and the unit call time is calculated. Since the current call charge is calculated from the charge and the counted call time, the total call charge during or after the call can be displayed on the key telephone on the receiving side.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a key telephone device according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a key telephone device of the present invention. In FIG. 1, the key telephone device is a main device 11 connected to a public line.
And a telephone 13 with a display connected to the main unit 11.
And have. The main device 11 is a telephone 13 with a display.
It has a telephone interface 12 connected to a public line and a station line interface 14 connected to a public line. Further, the central processing unit 15, the own telephone number storage unit 16 for storing the own telephone number in advance, and the calling side telephone number storage unit 1
7, a regional charge information storage unit 18 that stores charge information in which distances and regions are related in advance, and a call charge calculation unit 19.

The central processing unit 15 controls the telephone interface 12, office line interface 14, own telephone number storage unit 16, calling side telephone number storage unit 17, regional charge information storage unit 18, and call charge calculation unit 19. ing.

Next, the operation of the configuration of this embodiment will be described. When there is an incoming call from the public line to the office line interface 14, the central processing unit 15 causes the telephone set with display 13 to receive an incoming call through the telephone interface 12.

At the same time, the telephone number of the calling side sent from the public line is identified by the central processing unit 15 and stored in the telephone number storing section 17 of the calling side. The central processing unit 15 refers to the area-based charge information stored in the area-based charge information storage unit 18, and stores the own telephone number previously registered in the own telephone number storage unit 16 and the calling side telephone number storage unit. Using the calling party telephone number stored in 17, the call charge calculator 19 calculates the call charge from the start of the call to the present. That is,
The call charge per unit time is obtained from the charge information of the distance and the call time zone, and the call charge is added for each unit time of this call to calculate the total call charge.

Then, the total call charge is sent to the telephone 13 with a display unit through the telephone interface 12 under the control of the central processing unit 15 every unit time, and the telephones with a display 13 (not shown) are sequentially displayed. . Alternatively, a voice synthesizing device (not shown) of the telephone set 13 is used to voice-synthesize the call charge and output the voice after the call ends.

As described above, according to the above-described embodiment, the total call charge can be displayed even during a call, so that the call charge borne by the caller should be taken into consideration and long-term phone call prevention and call reception from the callee side. You will be able to encourage another call.

[0017]

As is apparent from the above description, the key telephone device of the present invention determines the unit call time charge for an incoming call from the identified calling side telephone number, own telephone number, and stored regional charge information. Since the present call charge is calculated from this unit call time charge and the counted call time, there is an effect that the total call charge during or after the call can be displayed on the key telephone on the receiving side.
