Description

How to opt out of certain calls.

The present invention relates to a method for rejecting a specific call in a communication terminal device, and more particularly, to a method for storing a rejection number and automatically rejecting the call.

The communication terminal apparatus includes a telephone, a facsimile, and the like. The present invention will be described below by taking a telephone terminal connected to an exchange system for providing a calling party telephone number.

Conventionally, a telephone terminal has no choice but to answer an unnecessary call by generating a ring tone to answer a call even where a call comes from.

However, in the future, the exchange that provides the caller ID (CALLER ID) service that informs the caller's telephone number is expected to become practical, and thus the terminal receives the caller's telephone number from the exchange. Therefore, since the user can know the caller's telephone number, the user can be given a function of selecting a specific telephone number and refusing the reception.

Accordingly, an object of the present invention is to provide a method of storing specific rejected telephone numbers in a telephone terminal connected to an exchange system providing a calling party number and automatically rejecting corresponding numbers.

The communication terminal apparatus for achieving the above object, the process of storing the caller's telephone number for the call in the call mode in the caller information buffer, and selects the phone number while sequentially searching the caller information buffer in the rejection call registration mode Registering a rejected call list, and comparing the caller's telephone number corresponding to a call detected with the numbers registered in the rejected call list, and rejecting the reception when the call is identical.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a telephone terminal according to an embodiment of the present invention.

The control unit 10 controls the overall operation of the telephone terminal according to the program. The memory unit 20 built in the controller 10 stores a program for controlling the telephone terminal and temporarily stores data generated while the program is being executed. The operator panel 30 (hereinafter referred to as OPE) is composed of key metrics including a plurality of numeric keys and provides key data generated by key operation to the controller 10 and is operated by the control of the controller 10. Display the status. The circuit interface 40 is a device for receiving or transmitting a voice signal from a telephone line, and particularly includes a demodulator for converting an analog caller information signal into a digital signal. The call tone generator 50 may generate a call signal when a call signal is detected from the subscriber line under the control of the controller 10, and may be adjusted so as not to generate a call signal when the call is received by the subscriber. The voice signal generator 60 is a device for generating a voice signal to be sent to a rejection caller, and is configured as a player for recording and reproducing a voice of a howler or a talker.

2 is a flowchart illustrating a method for manually registering a phone number of a rejected phone list according to the present invention.

First, the control unit 10 checks whether the reject call registration mode key is input in step 211. In this case, when the rejected call registration mode key is input, the controller 10 displays a telephone number input request indication in OPE30 in step 213 and proceeds to step 215.

In step 215, the controller 10 displays the telephone number entered by the user in OPE30, and checks whether a registration key is input in step 217. If the registration key is not input in step 217, the control unit proceeds to step 221 and checks whether an end key is input. If the registration key is input, the controller proceeds to step 219.

Then, the controller 10 registers the registered telephone number in the rejected call list in step 219, and checks whether an end key is input in step 221. In this case, if the end key is not input, the controller returns to step 213 to execute the program again from step 211 to step 221, and if the end key is input, the program ends.

3 is a flowchart illustrating a method for automatically registering a phone number of a rejected call list according to the present invention.

First, the control unit 10 checks whether the reject call registration mode key is input in step 311. If the rejection call registration mode key is not input, the controller 10 proceeds to step 313 to perform the corresponding mode. If the rejection call registration mode key is input, the control unit 10 proceeds to step 315.

Then, the controller 10 sequentially displays the telephone numbers stored in the caller information buffer in the OPE30. In step 317, the controller 10 selects a phone number designated by the user. In step 319, the controller 10 checks whether a registration key is input. In this case, if the registration key is not input, the process returns to step 315 to search for the caller information buffer and selects the number again. If the registration key is input, the process proceeds to step 321.

The controller 10 registers the phone number in the rejected phone list in step 321 and proceeds to step 323. At this time, the control unit 10 checks whether the end key is input in step 323, if the end key is not input, returns to step 315 to execute the program again, and when the end key is input, the program ends.

4 is a flowchart illustrating an operation for rejecting a specific caller according to the present invention.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to FIG. 4.

First, when a call is received from the outside, the controller 10 detects the call in step 411 and detects the caller information signal by the demodulator in the line interface 40 in step 413. The detected caller information signal is analyzed according to the protocol of the exchange system providing the caller number, and the controller 10 displays the caller number on the OPE30 in step 415.

In this case, the controller 10 inquires the rejected telephone list in step 417 and checks whether the telephone number is the rejected telephone number in step 419. In this case, in step 421, the controller 10 operates the voice signal generator 60 to transmit a howling signal to the caller, or records and reproduces the caller's voice. On the other hand, in the case of a normal phone, the controller 10 generates a ring tone to induce a call in step 427.

The voice signal generator 60 continues to operate until a ring signal does not come in at step 423, and the controller 10 continuously checks whether the user hooks off at step 429. The voice signal generator 60 stops the operation when the caller gives up the call attempt in step 425 under the control of the controller 10. Therefore, the terminal enters the standby state.

The controller 10 generates a ring tone in step 427 and checks whether the user hooks off in step 429. In this case, if the user does not hook off, the process proceeds to step 423 to check the ring signal. If the user hooks off, the controller 10 proceeds to step 431.

The control unit 10 stores the caller's telephone number in the caller information buffer in step 431, and stops the call tone or voice signal generator 60 under the control of the control unit 10 in step 433 to make a call.

As described above, the present invention can automatically reject a call to a specific telephone number by storing a specific rejected telephone list in a telephone terminal in an exchange environment that provides a caller ID service informing a caller's telephone number.

In other words, there is an advantage that can conveniently and efficiently respond to calls that do not require a reply, such as habitual prank calls, threatening calls, propaganda calls.
