Abstract

PROBLEM TO BE SOLVED: To protect the privacy of the user by registering telephone numbers of callers which are undesirous to display depend upon circumstances or conditions of the user in a telephone system capable of displaying the telephone number of a caller. SOLUTION: When data representing a telephone number of a caller in an incoming call through a public line are detected, a decoder 12 demodulates the data. The demodulated data are sent to a CMS control circuit 13 and once stored. Then a control circuit 22 discriminates whether or not the received telephone number of the caller is the telephone number registered in a memory 15 and set not to be displayed. When the telephone number of the caller is the telephone number registered in advance in the memory 15, the displayed telephone number is replaced with a camouflage telephone number registered in the memory 15. Then the telephone number of the caller or the telephone number data registered in the memory 15 for replacement are sent to a slave set 20.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device, and more particularly to a telephone device that uses a service for notifying a caller's telephone number.

[0002]

2. Description of the Related Art In recent years, a caller telephone number notification service for notifying a caller's telephone number to a partner terminal has been used. In Japan, a digital telephone using an ISDN line, a digital mobile phone such as PHS, PDC, etc. It can be used by phone.

Also, some telephone companies in the United States and Canada have 120 seconds per second during the first and second ringing pauses.
The CALL-ID service that transmits the caller's telephone number and name at a communication speed of 0 bit is implemented, and in response to this service, the received caller's telephone number is displayed on the display device provided in the telephone device. Display the CMS (Call Managim
A telephone device having an ent system) function has been developed.

For example, as described in Japanese Patent Application Laid-Open No. 3-96159 (H04M3 / 42), the name of the other party corresponding to the telephone number and other information are held as a table and received when an incoming call is received. There is also proposed a telephone device configured to display the name and other information held in the table based on the telephone number of the other party.

[0005]

By the way, in the telephone device having the CMS function corresponding to such a CALL-ID service or the telephone device disclosed in the above-mentioned publication, depending on the situation and the convenience of the called party, Even if you do not want to display the telephone number of the other party, there is a problem that all the telephone numbers sent from the caller are displayed. Therefore, the present invention allows the user to select whether or not to display the telephone number.

[0006]

In order to improve the above-mentioned prior art, the present invention is a telephone device having an indicator for displaying the telephone number of a caller sent through a line. Memory means for registering, means for judging whether or not the sent telephone number is stored in the memory means, and control for controlling display of the sender number according to the judgment result of the judging means. It is characterized by having means.

According to the present invention, the telephone number which is not desired to be displayed is stored in the memory means together with another telephone number to be displayed in place of the telephone number, and the caller number is stored in the memory means. In this case, the other telephone number is displayed.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration when the present invention is used in a cordless telephone device with a CMS function. In the figure, reference numeral 10 is a master unit, and 20 is a slave unit. Base unit 1
0 is connected to a public line, and wirelessly communicates with the child device 20 to make a call.

Reference numeral 11 is a line control circuit for controlling the disconnection and connection of the line, 12 is a decoder for demodulating an FSK-modulated signal indicating the telephone number of the caller sent through the line, and 13 is a demodulated telephone. A CMS control circuit for processing numbers and controlling CMS functions, 14 a control circuit for controlling the entire base unit 10, 15 a memory for storing data of telephone numbers that the user does not want to display, and 16 a handset 20 Reference numeral 17 denotes a radio circuit for performing radio communication with and.

Further, 21 is a wireless circuit for performing wireless communication with the master device 10, 22 is a control circuit for controlling the entire slave device 20, 23 is display means for displaying various information, and 24 is a ten-key pad or the like. Is an operation button, 25 is a receiving speaker, 26 is a transmitting microphone, and 27 is an antenna.

In the memory 15 of the master device 10, the slave device 2 is stored.
By operating the operation button 24 of 0, the telephone number which is not desired to be displayed and the telephone number for the camouflage which is desired to be displayed instead are registered.

Next, the operation of the present invention will be described with reference to the flow chart shown in FIG. When the processing is started, first, at step 100, when it is detected that the CALL-ID data representing the caller's telephone number is transmitted along with the incoming call through the public line, the decoder 12 demodulates the FSK-modulated data. (Steps 101 and 102). The demodulated data is sent to the CMS control circuit 1 in step 103.
3 and is temporarily stored.

Next, in step 104, the telephone number of the caller sent through the line is stored in the memory 1 by the user.
The control circuit 22 determines whether the telephone number registered in No. 5 is set not to be displayed. Step 104
Then, the sender's telephone number is recorded in advance by the user.
If it is the telephone number registered in, the telephone number data for camouflage registered in the memory 15 is replaced in step 105.

Then, in step 106, the telephone number data of the caller or the memory 15 is sent to the child device 20.
The telephone number data for replacement registered in the device is transmitted, and in step 107, the display device 2 is operated based on the data.
3 is displayed.

As described above, in the telephone device according to the present invention,
It is determined whether the caller's telephone number is a telephone number registered in advance by the user, and the telephone number is displayed as it is or an alternative telephone number is displayed.

In this embodiment, the case where the present invention is applied to the cordless telephone having the CMS function corresponding to the CALL-ID service which is provided in North America has been described, but the present invention is not limited to the cordless telephone. , And any telephone device capable of receiving telephone service in which the caller's telephone number is notified, such as ISDN
