How to Track Caller's Phone Number on Your Phone

The present invention relates to a method for tracking a caller's telephone number in a telephone, and more particularly, to a method for tracking a caller's telephone number in a busy state when a prank call is received.

Recently, as phone violence and mischievous phone calls have increased, subscribers are demanding services to verify the calling party's phone number. Therefore, techniques for verifying caller's telephone number using exchange system are being developed. Therefore, in the prior art, after applying for the phone number tracking service that was sent to the telephone company as a prank, when the prank was received from the outside, the user dialed the black switch on hook-off hook-on hook-off hook-155 during the direct call. An action was taken to enter the caller's phone number. In other words, 155 dialed after the hook flash 2 times in the state of the prank call. The exchange then recognizes the caller service request command and services the caller's telephone number by phone.

As such, in the related art, the hook switch is operated twice to perform the hook flash operation to receive the caller's telephone number, and then dialing is performed for the number 155. If the hook switch is pressed too long or too short, the hook flash operation is performed. This is not done properly can not receive the caller phone number service, there was also a cumbersome problem to dial the number 155 to receive the caller phone number service.

Accordingly, an object of the present invention is to provide a caller phone number tracking method that can track the caller's telephone number received from the exchange by pressing the one-touch key of the phone to solve the above problems.

In order to achieve the above object, the present invention is characterized in that it automatically hooks a flash when one-touch key is pressed on the telephone, and automatically dials a number for receiving the caller's telephone number to receive and track the caller's telephone number from the exchange. .

2 is a control flowchart for automatically tracking a caller's telephone number according to an embodiment of the present invention.

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

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

The CPU 130 controls the overall operation of the phone and controls the caller's phone number to be serviced by dialing the hook flash operation and numbers when the caller's phone number tracking key signal is input. The key matrix 100 includes a caller's telephone number tracking key, numeric keys for performing various functions and dialing functions, and outputs key data corresponding to a key pressed by the user to the CPU 130. The memory 220 is composed of a ROM for storing various programs and a RAM for temporarily storing data generated during the execution of the program. For example, the number 155 is used for the data and the number for the hook-on-hook-off-hook-on-hookoff. Has an area to store. The voice processor 150 voice-processes the voice signal for the call connected to the trunk line. The hook switch 160 is connected between the telephone line and the voice processing unit 150 and is operated when the user listens to the handset to connect the call path. The microphone 200 inputs a voice signal. The speaker 190 outputs an electric voice signal as an audible signal. The first and second amplifiers 170 and 180 amplify and output the input / output signals of the microphone 200 and the speaker 190 to a predetermined level. The display device 120 displays each processing and operation state according to the key input state. The DTMF generator 140 generates a DTMF signal under the control of the CPU 130 and provides it to the voice processor 150. The ring detection circuit 210 detects a ring incoming from the trunk line and provides the ring to the CPU 130.

2 is a control flowchart for automatically tracking a caller's telephone number according to an embodiment of the present invention.

1 to 2, the operation of the preferred embodiment of the present invention will be described in detail.

In order to carry out the present invention, the data 220 and the number 155 for hook-on-hook-off-hook-on-hookoff must be stored in the memory 220. Then, when a call is received, the user presses the caller's telephone number tracking button provided in the key matrix 100 when the user answers the call. At this time, the CPU 130 detects that the caller's telephone number tracking button is pressed and reads the data and numbers for the hook flash stored in the memory 220. The CPU 130 then controls the hook switch 160 to automatically dial the number read after the hook flash operation. Then, the exchange recognizes the caller's phone number verification service and transmits the caller's phone number as voice data. At this time, the CPU 130 controls the voice processing unit to form a call path to receive voice data for the caller's telephone number so that the user can listen through the speaker 190. As described above with reference to the flowchart of FIG. 2, when the user presses the caller's phone number confirmation button, the CPU 130 controls the caller's phone number to be automatically checked and tracked. If a call is received, the user will receive a call using the handset. In step 102, the CPU 130 determines whether a call is in progress. When the handset is in a hook-off state, the CPU 130 recognizes the call. If the user answers the call and presses the caller's telephone number tracking button, the CPU 130 receives the key signal pressed by the user from the key matrix 100 in step 103. Then, in step 104, the CPU 130 searches whether the received key signal is a caller's telephone number tracking key signal. If the received key signal is the caller's telephone number tracking key signal, the process proceeds to step 105, in which the hook flash information and the number registered in the memory 220 are read, the hook flash operation is performed automatically, and then the dialed number is dialed. The hook flash information is information that repeats the hook flash operation twice such as hook on-hook off-hook on-hook off, hook on for 1 second, hook off for 1 second, hook for 3 seconds, and then hook It turns off. Then dial 155, which is stored in memory 220. At this time, the exchange receives the hook flash information and the numeric information and recognizes the caller's telephone number tracking function and sends the caller's telephone number by voice. Then, in step 106, the CPU 130 controls the voice processing unit 150 to connect the normal communication path and receives a voice signal for the caller's telephone number provided from the exchange through the speaker 190. In operation 107, the caller's telephone number is output through the speaker 190 for the user to listen to.

As described above, the present invention, when a prank call is received from the outside, when the user presses the caller's phone number tracking button automatically hook-flash operation and numbers are automatically dialed to track the voice message for the caller's phone number, so that the user directly There is no need for cumbersome key operation for hook flash operation and dialing, and when the user performs the hook flash operation manually, the switch does not recognize the hook flash operation at the exchange because the user presses the hook switch too long or presses it too short. There is an advantage that can prevent you from receiving number services.
