Abstract

PURPOSE:To surely prevent annoying calls or the like by providing a means which compares calling subscriber information with terminal information and raises a ringing tone of a terminal equipment in case of coincidence. CONSTITUTION:When calling subscriber information is transmitted from a transmission terminal, this information is inputted to a comparing circuit 14. This circuit 14 compares terminal information stored in the storage circuit 13 and calling subscriber information with each other. If they coincide with each other, a call signal generating circuit 10 and a buzzer or bell 11 are connected by a call control circuit 15 to transmit the ringing tone. If they do not coincide with each other, the call signal generating circuit 10 and the buzzer or bell 11 are not connected.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention prevents prank calls, etc. by selectively ringing a receiving terminal based on caller information sent along with an incoming call signal from a caller. This invention relates to a terminal calling method that prevents

[Conventional technology]

FIG. 3 is a block diagram showing a communication system based on a conventional paging method. In the figure, ■ is a switch network, and 2 is this switch.

3 is a common control device that controls the switch network 1 and the subscriber circuit 2; 4 is a digital telephone that is accommodated in the switch network l via the subscriber circuit 2; A signal transmission circuit that transmits a signal to the subscriber circuit 2; 6 is the subscriber circuit 2;
7 is an on-hook/off-hook detection circuit for the handset 8; 9 is a digital telephone control circuit for controlling the digital telephone 4 based on the signals from the signal reception circuit 6 and the on-hook/off-hook detection circuit 7; 10 is a ringing signal generating circuit that generates a ringing signal based on a signal from this digital telephone control circuit; 11 is a buzzer or bell that generates a ringing sound based on a signal from this ringing signal generating circuit; 12 is a ringing signal generating circuit from the ringing signal generating circuit IO; This is an incoming call indicator lamp that indicates an incoming call based on a signal, or an incoming call display that displays incoming call information.

Next, the operation of the calling method in the conventional communication system shown in FIG.

The common control device 3, which has learned of the incoming call to the digital telephone 4, notifies the signal receiving circuit 6 of the incoming call via the subscriber circuit 2.

Based on the signal transmitted to the digital telephone control circuit 9 via the signal receiving circuit 6, the digital telephone control circuit 9
Then, the caller information is transmitted to the calling signal generation circuit 10 along with the incoming call signal sent from the calling terminal.

Based on this signal, the calling signal generating circuit 10 produces a ringing sound using a buzzer or a bell 11, and also causes an incoming call indicator lamp or an incoming call display 12 to flash a lamp or display caller information. Next, when the on-hook/off-footer detection circuit 7 detects the off-footer of the handset 8, the digital telephone control circuit 9
Instructs the calling signal generation circuit 10 to stop generating the calling signal, and at the same time, the signal transmitting circuit 5. The off-hook status is notified to the common control device 3 via the subscriber circuit 2.

The common control device 3 controls the switch network 1 based on this signal to set up a communication path between the calling terminal and the digital telephone 4.

[Problem that the invention seeks to solve]

In the conventional calling system as described above, a ringing tone is issued uniformly when a call arrives. For this reason, there is a problem in that even when a call arrives that the receiver wishes to reject, a ringing tone is emitted regardless of the receiver's convenience or situation. This invention was made in order to solve this problem, and aims to provide a terminal calling method that selectively produces a ringing tone based on caller information sent from a calling terminal. .

[Means for solving problems]

Therefore, in the terminal calling method according to the present invention, when the calling party information is sent from the calling terminal to the terminal device along with the incoming call signal, the comparing circuit compares the calling party information and the terminal information, If this happens, the terminal device will ring.

[Effect]

The comparison circuit provided in the terminal device according to the present invention is
When calling party information is sent from a calling terminal along with an incoming call signal, the terminal information stored in the memory circuit provided in the terminal device is searched and the calling party information and terminal information are combined. Make a comparison. If the calling party information and the terminal information match, the terminal device rings.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a block configuration diagram showing a communication system that performs a terminal calling method, which is an embodiment of the present invention.
.about.12 are the same as the conventional device described above. 13 is a storage circuit that stores terminal information such as a telephone number; 14 is a comparison circuit that inputs and compares the terminal information stored in the storage circuit 13 and caller information from the digital telephone control circuit 9; 15; is a calling signal control circuit that performs control using the output signal of this comparison circuit 14.

Next, the operation of an embodiment of the present invention configured as described above will be explained with reference to FIG.

First, when calling party information is sent from a calling terminal, the calling party information is manually entered into the comparison circuit 14 (step SI).

This comparison circuit 14 compares the terminal information stored in the storage circuit 13 with the calling party information sent from the calling terminal (step S2).

If the terminal information and the caller information match, the call control circuit 15 connects the call signal generation circuit 10 and the buzzer or bell 11 to produce a ring tone (step S). Further, if the terminal information and the calling party information do not match, the calling signal generation circuit 1 by the calling control circuit 15
0 and the buzzer or bell 11 are not connected, thereby preventing the ringing sound from being emitted (step S4).

In the above embodiment, a digital telephone was taken as an example, but similar effects can be achieved with other terminals such as data terminals.

〔Effect of the invention〕

As described above, in the present invention, when calling party information is sent from a calling terminal to a terminal device, a comparing circuit compares the calling party information and pre-stored terminal information, and if they match, Since the terminal device is configured to ring, you can stop ringing for calls other than important calls at night.
This provides an excellent effect in that nuisance calls can be prevented extremely reliably and stably.
