The present invention relates to an automatic continuous call method in which a telephone number of a party to be called is automatically dialed in an automobile telephone and a portable telephone without a redialing in a state in which a telephone number of a counterpart is set in a memory using a speed dial function. will be.

Conventionally, for example, if there are three places you want to make a call, dial the phone number of the place you want to call first, dial the phone number of the place you want to call the next time, Then repeat the process of dialing the phone number where you want to call. In addition, if the phone number of the place to be called is busy, the user must wait and try again, or dial the number of the place to be called next. This has the inconvenience of frequently dialing, and in the case of an automobile phone, there is also a risk of disturbing driving in a running car.

Conventional automobile telephones with a built-in speed dialing function to solve the above problems have stored a phone number in a two-digit memory address, and then, if a user wants to make a call to the phone number stored in the memory address, the play button of the speed dialing function You can press (RCL) and the memory address number (xxx), but if you want to continue to make a call to a different location, you need to keep dialing the speed dial play button (RCY) and the memory address number (xxx). have.

Accordingly, the present invention has been made in order to solve the above problems, in an automobile phone and a portable phone, when you want to talk to a number of call partners, the call is automatically dialed in sequence without dialing the phone numbers of the call participants The object of the present invention is to provide an automatic continuous call method for the convenience of the user.

In order to achieve the above object, the present invention is to search whether the transmission state in the idle mode to store the telephone number in the memory for speed dialing if the transmission state is not, and when the transmission state is a key for automatic continuous call function selection After the first step of searching whether the input has been entered, and after performing the first step, if the key for the automatic continuous call function has not been entered, the normal transmission mode is performed, and when the call is terminated, the mobile station returns to the idle mode of the first step. After performing the second step and the first step, if a key for the automatic continuous call function is inputted, storing the telephone number of the memory address for the first speed dialing stored in the buffer, performing a normal transmission mode, and searching for a call. After the step 3 and after performing the third step, if the call is not busy, the call mode is terminated and the call is terminated. Is inputted, and if the call is input, the user inputs an end signal when the user ends the call or is in a call after performing the fourth step. If the phone number of the stored memory address for the next speed dialing is specified, the phone number of the memory address for the next speed dialing is returned to the idle state of the first step. And a fifth step of storing the telephone number of the memory address for dialing in the buffer and repeating the second and third steps.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a schematic configuration diagram of an automobile telephone and a portable telephone to which the present invention is applied, in which 1 is a main CPU, 2 is an EEPROM, 3 is a RAM, 4 is an input / output port, 5 is a transmission data output terminal, and 6 is a transmission modulation. Input stage 7 is LCD, 8 is keypad, 9 is LCD driver and CPU, and 10 is hook sensor.

In the automobile telephone and portable telephone to which the present invention is applied, as shown in FIG. 1, the main CPU 1 includes an EPPROM 2 and a RAM 3, an LCD driver, a CPU 9, and an input / output port 4. A transmission data output terminal 5 is connected to the input / output port 4, a transmission modulation input terminal 6 is connected to the transmission data output terminal 5, and an LCD 7 is connected to the LCD driver and the CPU 9. ) And the keypad 8 and the hook sensor 10 are connected.

To use the automatic continuous call function, select the function with the key of the keypad (8), and when the function selection data is transferred to the main CPU (1) through the CPU (9) of the handset, the main CPU (1) is connected to the EEPROM (2). Access the main program in the program to run the program. And the phone number desired for the automatic continuous call function is input through the LCD (7). When the user inputs the dialed number into the dialed number through the key on the keypad 8 and presses the transmit key, the main CPU 1 displays the user among the phone numbers stored in the RAM 3. The first telephone number selected is selected and transmitted to the modulation input terminal 6 through the transmission data output terminal 5 through the input / output port 4. If the other party is busy or the call is over, press the end key (END) of keypad 8 or put the handset on the cradle and the hook sensor 10 detects this and automatically dials the next phone number. .

2 is a flowchart illustrating an automatic continuous call method of an automobile telephone according to the present invention.

The automatic continuous call method of the automobile telephone according to the present invention is briefly described as follows.

If there are three places you want to make a call, the phone number of the place you want to call first is stored in the memory using the speed dialing function. That is, memorize "xxx-xxx-xxx1", the telephone number of the place where you want to make a call, to memory address "01", and store "xxx-xxx-xx2x", the memory number of another place, to make a call. "Xxx-xxx-x3xx", another phone number you want to make a call to "03", and then "xxx-xxx-xxx1, xxx-xxx-xx2x, xxx-xxx- If you want to make a call in the order of x3xx ", press the function key, the send key, and the memory address in order to use the automatic continuous call method. Press "FCN * SND * 01 * 02 * 03" one by one. Then, first, the phone number of memory address "01" is attempted, and the call is attempted to the phone number of memory address "02" when the call is in progress or the call ends. If the call is over or busy, the phone number of memory address "03" is attempted. A call is attempted to. To signal a call to another telephone number that is busy or at the end of the call, signal by pressing the end key or placing the handset on the cradle. That is, if the phone number memorized in memory address "01" is busy, press the end key (END) or place the handset on the cradle. Take it.

On the other hand, if you want to stop the automatic continuous call while the car phone is performing the automatic continuous call function, press any key except the end key (END).

Referring now to the drawings in detail the processing procedure according to the present invention.

Idle Mode (100), which is a state in which a car phone is in a service area, waits, and determines whether the user presses a transmit key to attempt a call (110). Repeatedly stores the phone number in the memory by using the speed dial function until the end of the saving of the phone number on the call destination having the dialed number is completed (120, 130). When the transmission state is reached, the terminal searches for the key for the automatic continuous call function. If the key for the automatic continuous call function is not input, the normal mode is performed instead of the automatic continuous call function to perform the call mode for the call. As soon as the call ends, it returns to the original idle mode (220, 230).

If the transmission state is the automatic continuous call function selection state in which the key for the automatic continuous call function is pressed, the telephone number of the memory address for the first speed dialing is stored in the buffer and the transmission is performed (150, 160). In addition, the first speed dialing telephone call is checked (170), if the call is not in a call mode (180), and the user ends the call or presses the end key (END) or cradles the handset. If the state is placed on (190), the memory address for the next speed dialing is searched whether the phone number is specified (200). If the next phone number is not specified in the search result, the call to the desired destination of call is completed. Therefore, return to the first idle mode, and if there is a phone number of the designated memory address, enter the phone number of the memory address for the next speed dialing. Store in a buffer and enter the normal transmission mode to repeat the process (160 to 190) (210).

Therefore, the present invention performed by the above processing procedure automatically transmits the telephone number as many as the memory addresses for the designated speed dialing, so it is not necessary to dial the telephone number for each call. Convenience can be eliminated, and it can be applied not only to automobile phones but also to general home phones and portable phones with speed dialing.
