Abstract

The present invention relates to a method of redialing a series of phone numbers using a number increase / decrease key which can automatically increase or decrease a phone number to redial using a increase / decrease key. After the call is completed or the other party is busy, the first step of storing the currently dialed phone number in the memory means; and if you want to make a call to another serial number, the number increase / decrease key and the number to redial and redial key are input. A second step of checking whether the redial key is input after the check result increment key and the number to increase or decrease in the second step are input, and the number to be increased or decreased to the telephone number currently stored in the memory means in the first step. Redial by calculating and redialing the telephone number currently stored in the memory means in the first step if only the redial key is input. It is done in a third step.

The present invention relates to a method of redialing a phone, and more particularly, to a series of redialing methods using a number increase / decrease key, which automatically increases or decreases a phone number to be redialed using an increase / decrease key. .

In general, a company phone number is a serial number. In the conventional redial method, a telephone number stored immediately before is stored in a memory means and then resent by the redial function key. If the phone number to be redialed is a serial number that only needs to be changed by one digit, the existing redial transmission function for the conventional serial number is not available. There was no need to redial the phone number if only the last digit was wrong.

The present invention has been made to solve the above problems, and an object of the present invention is a serial number using a serial number increase and decrease key that can be automatically sent to the phone number to be redialed if the phone number to redial is a serial number To redial the phone number.

To achieve the above object, a feature of the redial method of a series of phone numbers using the number increase / decrease key according to the present invention is to complete a call after performing a call by inputting a phone number or the currently dialed phone number when the other party is busy. A second step of storing a number in a memory means, a second step of checking whether a number increase / decrease key, a number to be increased or a redial key are input if a user wants to make a call to another serial number, and a check result increase or decrease in the second step. If a redial key is input after a key and a number to increase or decrease are input, the redial key is calculated and redialed by calculating a number to be increased or decreased to the telephone number currently stored in the memory means in the first step. The third step is to redial the telephone number currently stored in the memory means. Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a series of phone number redial method using a number increase and decrease key according to the present invention will be described in detail.

1 is a block diagram showing a partial configuration of a telephone for implementing the present invention, as shown in the figure for selecting a number increase key (+) and a number decrease key (-) and redial functions for increasing or decreasing numbers; A key input unit 10 having a plurality of number keys (0-9) for inputting a redial key and a telephone number, and determines a key input state selected by the key input unit, and determines whether to increase or decrease the key according to whether the key is selected. A microprocessor 20 for selectively controlling a number to redial by performing an operation and a dialing unit 30 for transmitting a telephone number controlled by the microprocessor should be provided.

2 is an operation flowchart showing an embodiment of a series of phone number redial methods using a number increase / decrease key according to the present invention. As shown in the drawing, the first step is to enter a phone number and then make a call. (S11-S15) and the step of storing the telephone number currently dialed in the memory means (S16) when the check result is completed or the other party is in a call. Step S17 of checking whether or not you want to make a call and if you want to dial another serial number unless you want to make a call with a different serial number, it is checked if a number increase / decrease key and a number to increase or decrease are entered. Steps S19 and S20 and step S22 and S24 of checking whether a redial key is input are performed, and the third step is to increase or decrease the check result increment key in the second step. If a redial key is input after the number is input, calculating and redialing a number to be incremented or decremented to the telephone number currently stored in the memory means in the first step (S23); In the first step, it is preferable to redial the telephone number currently stored in the memory means (S25). Referring to the configuration as described above will be described the operation of a series of phone number redial method using the number increment key according to the present invention. First, when a telephone number is input from the key input unit 10 by the user (Y branch of S11), the microprocessor 20 detects a key input state and dials the telephone number of the place where the user wants to make a call through the dialing unit 30. After transmitting and allowing a call to be made, the internal memory means stores the telephone number of the currently dialed place (S12-S16). At this time, if the user wants to make a call to a series of numbers by increasing or decreasing a number after a call (Y branch of S17), the user increases the number (+) (or number decrease key) through the key input unit 10. Press (-)) (Y branch of S19) and press the number key to increase (or decrease) again from the number key (Y branch of S21), then press the redial button (Y branch of S22). 20), so that the number is automatically increased (or decreased) by the microprocessor 20 and redialed to the desired place (S23), and then the process returns to the step (S13) of checking the call state. If only the dial key is pressed, the number stored in the current memory means is redialed (S25), and then the flow returns to the step S13 of checking the call state.

As described above, according to the method of redialing a series of phone numbers using the number increase / decrease key according to the present invention, it is not necessary to re-enter a similar phone number according to the automatic increase or decrease of the number to be redialed. have.

Claims (1)

After completing a call by entering a phone number and completing the call or when the other party is busy, the phone number that was dialed is stored in the memory means, and the number is increased or decreased using the number increase / decrease key to increase or decrease the number. In the dialing method, if a redial key is input after an increase / decrease key and a number to increase / decrease are input in order to make a call to another serial number during a call, the number to be increased or decreased to the telephone number currently stored in the memory means is calculated. And redialing the phone number currently stored in the memory means when only the redial key is inputted.
