Abstract

PURPOSE:To prevent effectively a malicious call and a call from an undesired caller by setting a pass word in addition to a subscriber telephone number and confirming the pass word so as to exclude automatically a call from a person other than those knowing the pass word. CONSTITUTION:When a call takes place to a line 1 to a subscriber of a telephone set 3, a control section 28 responds to it, connects a voice response section 23 to the line and requests the transmission of a number being the pass word to the caller in voice. The pass word of the number by a voice transmitted from the caller is received by the voice response section 23, the pass word of the number in voice is converted into a digital signal, stored in a register 101 of the control section 28, compared with the pass word stored in a register 102 so as to check whether they are coincident with each other or not. When it is confirmed that they are coincident as the result of pass word check, a line control section 24 is activated and a call signal is transmitted to the telephone set 3.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a telephone device, and more particularly, to a telephone device that prevents a caller from receiving a call from an undesired party.

(Prior Art) Telephones currently in common use allow an unspecified number of people to call a subscriber using the telephone number of the telephone. This is a big advantage.

However, with such telephones, it is necessary to take some measures to cut out unwanted calls from the perspective of the recipient, such as when it is desired to permit only prank calls or calls from a certain limited number of people.

Conventionally, such requests have been responded to by not listing the phone number in the phone book or setting a secret phone number, but once the phone number is known, measures such as changing the phone number are taken. The disadvantage is that it is necessary and difficult to change.

(Object of the Invention) The object of the present invention is to add a specific code (hereinafter referred to as a password) in addition to a normal telephone number, and to make it possible to easily change the specific code. To provide a telephone device that can effectively prevent prank calls and calls from parties that one does not want to receive.

(Structure of the Invention) The device of the present invention includes a specific code setting means for setting a specific code that identifies a telephone corresponding to the telephone number in addition to the telephone number, and a device that instructs the caller to send the specific code after receiving a call. a specific code transmission requesting means for requesting, and a code comparing means for comparing the supplied code supplied from the sender in response to the request of the specific code transmission requesting means and the specific fixed code, and generating a match signal when they match. and connecting means for connecting the telephone and the caller's telephone in response to the supply of the matching 4M number.

(Embodiment) Next, an embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a book diagram showing one embodiment of the present invention. The telephone device shown in FIG. 1 is composed of a reception control device 2 and a telephone set 3. The telephone device shown in FIG. The telephone 3 is a normal telephone, and the reception control device 2 receives input from the line 1 between the telephone 3 and the line control unit 2.
A branch circuit 21 which branches into 4 and connects the output of the telephone 3 and the output of the line control unit 24 to the line IK, and Ml: a line control unit connected to the stain removal machine 3 connected to the line control unit 24. 24, a voice response unit 23 for requesting a password by voice from the sender or converting the password received as an audio signal into a digital signal, a switch 22 for switching the connection of the telephone 3, and a password input unit for inputting the password. 25, an 0N10FF circuit 26 for enabling or disabling the reception control device 2, a function key portion 27 for specifying the operational function of the reception control device 2, a line control section 24, and a voice response section 23. ．． Password input section 25゜0
N10F-F circuit 26 and function key part 27
The control unit 28 is connected to the control unit 28 to control the reception control device 2 and verify passwords.

Next, the operation of this embodiment will be explained.

In the initial state, the 0N10FF circuit 26 is in the ON state, and the reception control device 2 is in the operating state. Further, numbers determined in advance as a password are inputted from the password input section 25 and stored in the register 102 of the control section 28. Further, the telephone 3 is connected to the line control section 2 by the switch 22.
Connected to 4.

When a call is generated on the line 1 to the subscriber of the telephone set 3, the call is supplied to the line control section 24 via the branch circuit 21 of the reception control device 2. The line control unit 24 detects this call and notifies the control unit 28 of the call detection.

In response, the control section 28 sends a voice request to the voice response section 23 to request the caller to send a number as a password. do.

The voiced numerical password sent from the caller is received by the voice response unit 23, and the voiced numerical password is converted into a digital signal and sent to the register 1 of the control unit 28.
It is stored in 01. Here, the control unit 28 compares the password stored in the preset register 102 and the received password stored in the register 101 to check whether they are the same.

If it is confirmed that the passwords are the same as a result of the password check by the control unit 28, the control unit 28 transmits the passwords to the line control unit 24.
The telephone 3 is activated to send a calling signal to the telephone 3, and when the handset is disconnected, the line control section 24 operates the switch 22 to connect the telephone 3 to the x4C line and make a call possible. At the end of the call, the switch 22 switches the telephone 3 to the line controller 2.
411? :Connecting.

If the passwords do not match in the password check by the control section 28, the control section 28 instructs the voice response section 23 to send a message requesting retransmission of the password. The control section 28 instructs the line control section 24 to disconnect the call connection when the password is retransmitted a predetermined number of times or more or when no match is found in the password check within a certain period of time.

In the case of a call from telephone 3, switch 22 switches telephone 3 to connect to line 1, allowing it to operate as a normal telephone. The entire reception control device 2 is a 0N10FF circuit 26
J) If it is OFF, the switch 22 will switch to the telephone 3.
Connect to line l.

The key operation for function key part 27 is performed by the reception control device 2.
For example, the operation time and end time of the reception control device 2 are specified.

If the password that has been set becomes known to someone other than the designated person and it becomes necessary to change the password, all that is required is to input the new password from the password input section 25 and notify the person concerned. You can change your password.

As described above, in this embodiment, calls from anyone other than those who know the password can be automatically excluded.

(Effects of the Invention) The present invention has the ability to automatically eliminate calls from anyone other than those who know the password by setting a password in addition to the subscriber's telephone number and confirming the password. This has the effect of effectively preventing calls from individuals.
