Abstract

PURPOSE:To discriminate an incoming call from a specific caller in a sound only and to implement notice to a slave set as a usual call or a specific caller. CONSTITUTION:A telephone number of a registration request from registration circuits 14, 21 is stored in a memory 13, and a telephone number of a caller and a telephone number stored in the memory 13 are compared by a control circuit 12 at the arrival of a call. When a relevant telephone number is in existence, a speaker 15 or 22 of any of a master set 11, slave sets 20, 23 to n only sounds a call tone different from that of a usual call tone, and the other master set 11, the slave sets (20, 23 to n) sound a call tone the same as that the case with no relevant telephone number.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a parent-child telephone device that utilizes an ISDN caller telephone number notification additional service.
In particular, the base unit or slave unit identifies the phone number registered in the base unit and the telephone number of the other party when an incoming call is made, selects the corresponding base unit or slave unit, and changes the ring tone and makes the sound ring. , relates to a parent-child telephone device that identifies calls from specific parties.

0002

2. Description of the Related Art Conventionally, telephones connected to ISDN have been able to utilize an additional service that notifies the caller's number.

[0003] In such telephones, the caller number at the time of an incoming call is displayed on a display device such as an LCD provided in the telephone, and the receiver visually confirms the displayed caller number.

0004

[Problems to be Solved by the Invention] However, in the above-mentioned conventional ISDN telephone, it is difficult for the user (receiver) to identify whether or not the call is from a specific party that is important to him/her by using a display device installed on the telephone. The user visually checks the caller ID displayed on the screen and makes a decision based on his or her memory. in this case,
There were disadvantages such as having to interrupt work.

[0005]Furthermore, a parent-child telephone set in which a plurality of handsets are connected to a base phone has the disadvantage that the caller number cannot be reported to the handsets.

[0006] The present invention solves these conventional problems, and allows an incoming call from a specific destination to be easily identified by sound alone. The purpose of the present invention is to provide an excellent parent-child telephone device capable of sending notifications.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a registration means for registering a telephone number in the base unit, and a ring tone with a different sound quality than the normal time. In addition to providing a calling means for making a sound, a registration means for registering a telephone number in the base unit, a storage means for storing a telephone number instructed to be registered from the slave unit, a normal time, and a call with a different sound quality from the normal time. A calling means that makes a sound compares the telephone number at the time of the incoming call with the telephone number registered in the storage means, and if they are the same, selects and selects the base unit or slave unit in which the corresponding telephone number is registered. and a control means for controlling the sound quality of the base unit or the slave unit to be played in a different tone from the normal one.

[0008]

[Operations] The present invention has the following functions due to the above structure. In other words, when the recipient of an incoming call is a registered phone number, the corresponding base unit or handset is selected and the ringtone is changed and the ringtone is changed, so the user can receive an incoming call from a specific recipient. can be easily determined from the sound alone. It is also possible to send caller notifications to the handset, either normally or by specific caller.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 10 is an ISDN line network, 11 is a base unit, and 20, 23, . . . n are slave units.

[0011] The ISDN line network 10 is connected to a base unit 11. The base unit 11 has a control circuit 12, which stores the telephone number requested for registration in the memory 13, reads the stored telephone number, and also reads the telephone number transmitted from the ISDN network 10. Identify the phone number that comes from the phone. Furthermore, the control circuit 12 controls the handset 20, 23...n.
Control is performed to play the ringing tone during normal times and with different sound quality separately from the normal times. The base unit 11 also includes a registration circuit 14 equipped with a numeric keypad or the like for requesting registration of a telephone number, and a speaker 15 for transmitting a ring tone.

[0012] Handsets 20, 23...n connected to the base unit 11
are each provided with a registration circuit 21 for requesting the memory 13 in the base unit 11 to register a telephone number, and a speaker 22 for transmitting an incoming ring tone.

Next, the operation of the above embodiment will be explained. When there is a request to register a telephone number from the registration circuit 14 of the base unit 11 or the registration circuit 21 of the slave units 20, 23...n, the control circuit 12 sends the base unit 11 or the slave units 20 in the memory 13,
23...n stores the telephone number requested for registration in each storage area.

[0014] After this, from the ISDN line network 10 to the base unit 11
When there is an incoming call, base unit 11 compares the caller's telephone number with the telephone number stored in memory 13 and determines whether the corresponding telephone number exists or not.

If there is no corresponding telephone number, the control circuit 12 controls the speaker 15 of the base unit 11 and the slave unit 20.
, 23, .

[0016] Furthermore, if there is a corresponding telephone number, the base unit 11, handset 20, 23, etc. that requested the registration of the telephone number...
n only, speaker 15 or speaker 22
is blown with a normal tone quality, and the other base unit 11 and slave units (20, 23...n) are blared at the same time with normal tone quality.

As described above, according to the above embodiment, the telephone numbers of the parties important to the user are transmitted to the slave units 20, 23...n.
If the number is registered in the memory 13 of the base unit 11, the tone quality of the ring tone of the handset (20, 23, . . . n) can be changed from normal when the telephone number is called.

[0018] Therefore, it is possible to send a caller notification to the handsets 20, 23, .

Furthermore, in the base unit 11, it is possible to quickly understand that the call is from a specific and important party just by the sound without visually checking the display device provided on the base unit 11. In this case, the work is not interrupted and there is no need to rely on memory, making it less likely that mistakes will occur.

In the above embodiment, the memory 13 includes:
Although only one telephone number can be stored for each handset 20, 23...n, the memory 13 can store only one phone number for each handset 20, 23...n.
A plurality of telephone numbers may be stored for each n.

[0021]Also, in the above embodiment, the registered telephone numbers are different for the base unit 11, the slave units 20, 23...n, but the same telephone number may be registered between two slave units, for example. (20, 23...n) may be registered. Also, base unit 1
The same telephone number may be registered for the mobile device 1 and the handset (20, 23...n). In this case, for example, if the same telephone number is registered from the base unit 11 and the handset 20, then if the registered telephone number receives a call,
A speaker 15 of a master device 11 and a speaker 22 of a slave device 20 simultaneously emit sound with different sound quality than usual. At the same time, handset 23
.

[0022]

[Effects of the Invention] As is clear from the above-mentioned embodiments, the present invention selects the corresponding base unit or slave unit and changes the ringing tone when the other party at the time of an incoming call is a registered telephone number. This has the effect that an individual user can easily determine an incoming call from a specific important party based on the sound alone, without having to visually see the call.

[0023] It also has the effect of being able to send caller notifications to slave units, either normally or by specific recipients.
