Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call control method for a telephone terminal connected to an analog communication line or the like so that a service for notifying the calling party number of the other party can be used when an external call arrives.

[0002]

2. Description of the Related Art Conventionally, as one of the telephone services, there is a service for transmitting and displaying the calling number of the other party on a display provided on the telephone terminal of the receiving side when an outside line is received. It is set to the communication line. According to this caller number notification service, the operator (called person) of the telephone terminal on the receiving side sees the caller number displayed on the display unit at the time of receiving a call, and thereby confirms the caller number. You can check. In addition, by checking the calling party number, it may be possible to identify whether the call is to be answered or is not necessary to answer, such as a wrong call or a prank call.

An example of such a conventional telephone device is shown in FIG. In this conventional telephone device, when a caller side telephone device 10 connected to an analog communication line makes a call (call), a called party is called through an analog communication circuit device (switch etc.) 11. The called party side telephone device 12 includes a control side device (hereinafter, main device) 13 connected to an analog communication line and a telephone terminal connected to the analog communication line via the main device 13. 14 (two telephone terminals 14-1 and 14-2 in the illustrated example). The main device 13 includes a 16HZ detection circuit 15, a centralized control circuit 16 and a data transmission circuit 1.
7, the telephone terminals 14-1 and 14-2 each include a data transmission circuit 18, a display 19 and the like.

The flow of a call at the time of implementing the caller number notification service in this conventional telephone device is as follows. First, when a call is made from the telephone device 10 on the calling side, a 16HZ signal is transmitted to the main device 13 of the telephone device 12 on the called side via the analog communication circuit device 11 to receive an incoming call. After the 16HZ signal is detected by the 16HZ detection circuit 15, the centralized control circuit 16 and the data transmission circuit 17
Is input to the data transmission circuit 18 of the telephone terminals 14-1 and 14-2, and the incoming call is sounded at the telephone terminals 14-1 and 14-2.

[0005]

In the above-mentioned conventional telephone device, the caller number notification service allows the caller number of the other party to be displayed on the display of the telephone terminal when an outside line is received. The calling party number sent by the calling party number notification service is not being effectively used for call reception control. For this reason, all telephone terminals connected to the main unit are set to ring the incoming call, and the called party must select and judge the response related to the incoming call depending on the presence or absence of the ringing tone. It is configured as a side priority incoming call control method. Therefore, the above-mentioned conventional telephone device is not an easy-to-use telephone device that gives priority to the called party.

The present invention has been made by paying attention to such a conventional problem, and effectively uses the calling party number information transmitted to the called side telephone device by the calling party number notification service. It is an object of the present invention to provide an incoming call control method for a telephone terminal that can perform various effective incoming call controls.

[0007]

To this end, an incoming call control method according to claim 1 of the present invention uses a main device through a main line to a telephone line which can use a service of notifying the calling party number of the other party when an outside line is received. When controlling the incoming call of a telephone terminal that is connected by a call, when an incoming call is made to the main device in response to a call from the other party, the caller number is detected and the detected caller number is registered in advance. A predetermined incoming call control to one or both of a telephone terminal previously associated with the calling party number and a telephone terminal not previously associated with the calling party number. To do.

In the above, when the detected caller number is a preregistered caller number, the incoming call control is
The control for selectively ringing a telephone terminal preliminarily associated with the calling party number is performed by not ringing the telephone terminal unrelated to the calling party, so that This is preferable in order to realize the incoming call control with priority on the called party side, in which only the telephone terminal corresponding to the calling party rings.

In the above, when the detected caller number is a caller number registered in advance, the call reception control is such that a predetermined call is received by a telephone terminal group previously associated with the caller number. Control to make an incoming call ringing selectively with a ringing sound, and if all the detected calling party numbers are not the registered calling party numbers, ringing sounds to all telephone terminals with an incoming ringing sound different from the ringing sound. That is, by distinguishing the ringing tone from the incoming call, the called party can roughly understand who is the incoming call and can determine who should answer. This is preferable for realizing the side-first priority incoming call control.

In the above, when the detected caller number is a preregistered caller number, the incoming call control is:
The control is such that only the telephone terminal previously associated with the calling party number does not ring the incoming call, but the telephone corresponding to the calling party as intended by the called party who does not want to answer the calling party. This is preferable in order to realize call control on the called party side, in which only the terminal is rejected.

In the above, the incoming call control is a control for switching the incoming call ringing sound depending on whether the detected caller number is a local area code or an area code. This is preferable in order to realize the incoming call control with priority on the called party side so that the called party can identify whether the incoming call is a local call or a long distance call.

In the above, when the detected caller number is a preregistered caller number, the incoming call control is
Instead of issuing a ringing tone, the control is to display the calling party number on the liquid crystal display of the telephone terminal with a liquid crystal display function that is associated in advance with the calling party number, and a general ringing tone is used. In order to realize the incoming call control with priority on the called party side, which enables the called party to detect the incoming call without the need to know the calling party from the display of the calling party number. preferable.

In the above, when the detected caller number is a caller number registered in advance, the incoming call control is:
The control that allows the telephone terminal with an answering machine function pre-associated with the calling party number to receive a call even when the answering machine mode is set is that the call is received from a person other than a specific caller who is setting the answering machine mode. Is preferable in order to realize the incoming call control with priority on the called party side, which is confirmed later by a message and the incoming call from a specific calling party can be answered immediately.

[0014]

According to the incoming call control method of claim 1 of the present invention, in the telephone device connected via the main device to the telephone line which can use the service of notifying the calling party number of the other party when the outside line is received, the other party When an incoming call is made to the main device in response to a call from, the caller number is detected, and depending on whether the detected caller number is a pre-registered caller number, Predetermined incoming call control is performed for one or both of a telephone terminal that is associated in advance and a telephone terminal that is not associated in advance.
