The present invention relates to a redialing method of a communication apparatus, and in particular, stores the time between digits input during telephone number dialing and the digit number, and stores the same time between digits input during dialing when a redial key is input. The present invention relates to a redialing method for redialing a given number.

In general, faxes and telephones remember the last dialed telephone number, and then enter the redial key. Then, the dialer quickly dials the memorized number again before pressing the redial key.

However, when using a telephone, in order to catch a dial tone of a local exchange with a keyphone telephone or a private exchange, the system waits until each system's dial tone is heard, and then dials. Redial does not take into account the time spent waiting for dialtones and redials are not performed properly.

In addition, if you want to receive a variety of information using the telephone, dial the phone number and then dial the desired digit number according to the instructions of the voice guidance stored in the service information system. However, when dialing by the existing redial method in order to receive such various information services, the user cannot receive the desired information service because the user cannot dial in response to the voice guidance instruction. Therefore, since the user must directly press the dial key for receiving the information service according to the voice guidance, the number of digits to dial in the case of retrying the dialing has been inconvenient because it takes a lot of time and time. For example, if you want to call pager, press 012-252-3394 and press 1 to make a call from the answering machine or 2 to leave a message. Then dial your phone number, for example, 123-2345. At this time, 012-252-3394-1-123-2345 is stored in the dial buffer, and if you press the redial key to redial it, it redials speedily in batch regardless of the request of the auto-reply message. Could not receive pager call service because it did not recognize the dialing number.

Accordingly, an object of the present invention is to provide a redialing method for performing redialing in response to a request of an autonomous message so that information can be serviced in an autonomous device for solving the above problems.

Another object of the present invention is to store a number of digits input at the time of dialing and a time between each digit, and then provide a method of redialing the same time as the time of each digit previously dialed when the redial key is input.

In order to achieve the above object, the present invention counts the number for each digit inputted during dialing and the time between each input digit, and stores them sequentially, and when the redial key signal is inputted, the digits input during the dialing stored. It is characterized by redialing the number for the same time as the time between each digit.

1 is a block diagram of a system according to the present invention, wherein the central processing unit 10 receives a key input signal to control dialing, stores the input number, and stores the number when the redial key signal is input. Control to perform redialing, and generates various display control data. The OPE 20 includes a plurality of keys for generating a dial key signal, inputs the data to the central processing unit 10 when the key data is generated, and displays data by the control of the central processing unit 10. With a device. The memory 30 stores program data and problem data, and accesses or stores dial numbers under the control of the CPU 10. The DTMF transmitter 40 receives the dial number from the CPU 10 and performs dialing.

2 is a control flowchart for registering a dialing number according to the present invention;

3 is a control flowchart of redialing according to the present invention.

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 21, the central processing unit 10 checks whether a hook path (not shown) is hooked off to establish a call path, and then proceeds to step 22 when a call path is formed. In step 22, the central processing unit 10 checks whether a dial key is input from the OPE 20, and proceeds to step 29 if a dial key is not input, and proceeds to step 23 if a dial key is input. In step 29, the central processing unit 10 checks whether the call path is blocked and proceeds to step 22 again if the call path is not blocked, and ends the program if the call path is blocked. In step 23, the central processing unit 10 operates the internal counter and proceeds to step 24. In step 24, the CPU 10 dials a digit number corresponding to the input dial key and stores the digit number in the memory 30. Then, in step 25, the CPU 10 checks whether the next dial key is input from the OPE 20, and proceeds to step 30 if the dial key is not input. In step 30, the central processing unit 10 checks whether the call path is blocked, and if the call path is not blocked, proceeds to step 25 again and ends the program if the call path is blocked. However, if the next dial key is input in step 25, the process proceeds to step 26. The CPU 10 stops the operation of the internal counter and proceeds to step 27. In step 27, the CPU 10 stores the interval time from the previous dial key input time to the current dial key input time in the memory 30, and clears the internal counter. In step 28, the central processing unit 10 dials the digit number corresponding to the currently input dial key, and stores the digit number in the memory 30. After that, when the next dial key is input, the process returns to step 22, and steps 23 to 28 described above are repeatedly performed, and the number of dialed numbers and the waiting time between each input digit are repeatedly stored in the memory 30 until the dialing is completed. Save it.

When dialing is registered in the memory 30 by dialing as described above, the operation of redialing when the redial key is pressed will be described with reference to FIG.

In step 31, the CPU 10 checks whether a redial key is input from the OPE 20, and proceeds to step 32 when the redial key is input. In step 32, the central processing unit 10 reads the digit number first input at the time of dialing and stores the digit number stored in the memory 30 to control the DTMF transmitter 40 to perform dialing. In step 33, the central processing unit 10 reads the dial digit interval time from the memory 30, operates an internal counter, and proceeds to step 34. In step 34, the CPU 10 checks whether the read dial digit interval time has elapsed and proceeds to step 35 if the dial digit interval time has elapsed. In step 35, the CPU 10 clears the internal counter and proceeds to step 36. In step 36, the central processing unit 10 reads the next dial digit number from the memory 30, controls the DTMF transmitter 40, and performs dialing. In step 37, the central processing unit 10 checks whether a digit number to be dialed next exists, and if there is a digit number to be dialed, the process returns to step 33 again and repeats steps 34 to 37 described above to determine the digit number to be dialed. Redial until no longer exists.

The operation of redialing according to the flowchart of FIG. 3 after registering a dialing number through the private telephone → private exchange → local exchange according to the flowchart of FIG. 2 will be described below. When the key-phone subscriber wants to talk to the desired subscriber at number 460-2775 through the local exchange, the key-phone subscriber presses 9 of the key-phone telephone. At this time, the key-phone telephone dials the number 9 pressed by the private exchange and stores it in memory. Then, the key phone telephone is established with the private exchange. If the key phone subscriber presses 9 times 2 seconds after the key 9 is pressed, the key phone telephone saves 2 seconds between the first and second digits in memory. The number 9 is stored in memory, and the private exchange forms a currency path with the local exchange. Then, if the key-phone subscriber presses 4 → 6 → 0 → 2 → 7 → 7 → 5 in 1 second intervals three seconds after the second ninth press, the time between the second digit and the third digit on the key-phone telephone. Store 3 seconds in memory, then save 4 times. Then, the time 1 second between the third digit and the fourth digit is stored in the memory 30, and the sixth is stored in the memory 30. As described above, the time between the digit and the digit 1 second and 0 → 2 → 7 → 7 → 5 are sequentially stored in the memory 30 as shown in Table 1 below.

When the redial key is input after the dial number is stored in the memory of the key phone as shown in Table 1, redialing is performed.

When the subscriber hooks off the handset of the telephone phone and presses the redial key, the telephone phone reads the dial digit number 9 stored in the memory 30 and dials. The key-phone telephone reads and dials the second dial digit 9 again after 2 seconds. Then, after 3 seconds, the key-phone telephone reads and dials the third dial digit number 4 again, reads and dials the dial digit number 6 one second later, and reads and dials the dial digit 0 again one second later. Dial 2 → 7 → 7 → 5 in order of 1 second.

Here, although the key phone telephone and the private exchange have been described as an example, the redial function according to the present invention can be performed in a multifunctional telephone, a special service telephone, and a facsimile.

As described above, the dial key number and dial key input time inputted during dialing are stored in the memory, and when the redial key is input, the dial is redialed at the same time interval as when dialing. There is an advantage that can simplify the cumbersome key operation.
