The present invention relates to a redialing method of a telephone terminal device, and in particular, after a set time elapses between each digit inputted when dialing a telephone number in a telephone terminal device, the dialing number inputted is deleted in the redial buffer to perform the inter-digital communication. The present invention relates to a redialing method of redialing only a dial number entered within a set time interval.

In general, a facsimile or a telephone, after remembering the last dialed telephone number, enters the redial key, the dialed number is quickly dialed again at a predetermined interval before the redial key is pressed.

However, if you want to receive a variety of information using the telephone, dial the corresponding telephone number, and then dial the desired digit number according to the instructions of the voice guidance stored in the service information system. However, in case of retrying dialing to receive such various information services, not only a telephone number but also a control code is transmitted at a time, thereby causing an inaccurate call or abnormal operation of the service information system.

Accordingly, an object of the present invention is to check the time between each digit during the diling to solve the above problems, to delete the dial number after the digit interval exceeds a certain time in the dial buffer so as not to redial In providing a method.

Another object of the present invention is to provide a redial method for preventing a redial of a remote code whose time between digits input during dialing exceeds a predetermined time.

The present invention for achieving the above object, the process of storing the number for each digit input when dialing, the process of retrieving whether the input time between each digit has elapsed after storing the number for each digit; Deleting a dial number for a digit input after the set time when the input time between the digits has elapsed and the storing when the redial key is input after deleting the dial number. Characterized by consisting of a process of performing a redial by a dial number.

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

1 is a block diagram of a system according to the present invention, in which the CPU 10 receives a key input signal to control dialing, stores an input dial number in a dial buffer, and sets an interval time between digits of the dial number. Controls to delete the dial number after the abnormality is exceeded in the dial buffer, and to perform redialing with the number stored in the dial buffer when a redial key signal is input, and generates various display control data. The key input unit 20 includes a plurality of keys and redial keys for generating a dial key signal, and inputs them to the CPU 10 when the key data is generated. The display unit 30 displays data under the control of the CPU 10. The memory unit 40 stores a program for redialing the present invention, and accesses a dial number under the control of the CPU 10. The dialing unit 50 receives a dial number from the CPU 10 and performs dialing.

2 is a control flowchart for registering a dialing number according to the present invention, and FIG. 3 is an exemplary diagram of cadence of a ring signal.

One preferred embodiment of the present invention will be described in detail with reference to FIGS.

An operation of registering a digit number corresponding to an input dial key during dialing will be described with reference to FIG. 2. FIG.

First, in step 101, the CPU 10 checks whether a hook switch (not shown) is hooked off and a call loop is formed, and then proceeds to step 102 if a call loop is not formed. In step 102, the CPU 10 clears a flag, a head, and a tail to 0 and proceeds to step 103. Here, Head is data representing a dial input position, and Tail is data representing a dialing position. In step 103, the CPU 10 sets the dial buffer BUF (Head) to Null and terminates the program. However, if the call loop is formed in step 101, the CPU 10 inputs the dial key from the key input unit 20 and proceeds to step 105. In step 105, the CPU 10 checks whether the input unit dial key value is a valid value from the key input unit 20, and returns to step 101 if it is not a valid key value, and proceeds to step 106 if it is a valid value. In step 106, the CPU 10 stores the input dial key value in the key register KEY-R, and proceeds to step 107. In step 107, the CPU 10 stores the dial key value stored in the key register in the dial buffer BUF [Head] and proceeds to step 108. In step 108, the CPU 10 increments the head indicating the dial input position by one and proceeds to step 109. In step 109, the CPU 10 checks whether a flag value for setting a remote code is 0. That is, it is checked whether the set time between digits has elapsed. If the flag is 0, it is determined that the set time between digits has not elapsed. If the flag is 1, it is determined that the set time between digits has elapsed. . Therefore, if the flag is not 0, the process returns to step 101. If the flag is 0, the process proceeds to step 110, and it is checked whether 4 seconds, which is a set time, has elapsed. At this time, if 4 seconds have elapsed, proceed to step 111 to set the flag to 1 and proceed to step 112. In step 112, the CPU 10 sets the redial buffer R-BUF to NULL and returns to step 101. However, if the timer has not elapsed 4 seconds in step 110, the process proceeds to step 113 to reset the timer and proceeds to step 114. In step 114, the CPU 10 stores the dial key value stored in the key register KEY-R in the redial buffer R-BUF [Head], and returns to step 101 to repeat the above-described operation. In this way, when dialing the registered dial number in the memory 40 and then pressing the redial key again, only the phone number is redialed without being dialed.

An example of an operation of redialing after registering a dialing number according to the flowchart of FIG. 2 is described below. When calling the answering machine by dialing the desired telephone number 700-1000 # 1 1234 #, the answering machine usually operates after ringing two or more times when dialing 700-1000. Therefore, when the ring rings twice, as shown in FIG. 3, at least 4 seconds are required to operate the auto answering system after 1 second of ringing, 2 seconds of rest, and 1 second of ringing again. Here, for example, although the setting time is set to 4 seconds, it may vary depending on the link cadence setting. Therefore, after 4 seconds, # 1 1234 # must be dialed again, so the kit value dialed after 4 seconds is deleted from the dial buffer. When the redial key is input, the telephone number 700-1000 is redialed.

As described above, by checking the time between each digit inputted during dialing, the dial number after the digit interval exceeds a certain time is removed from the dial buffer to prevent redialing, thereby preventing the remote code from being dialed. There is an advantage.
