Description

How to automatically delete and add area codes when speed dialing on a digital cordless phone

The present invention relates to a method of speed dialing and one-touch dialing (hereinafter referred to as "speed dialing") in a digital wireless telephone. In particular, the speed dialing method automatically deletes and adds an area code by distinguishing an area requiring an area code from an area that is not needed. It is about a method.

In general, a digital generation telephone (CT2) is connected to the PSTN network through a wireless base station called telepoint to form a call path. The telepoint is connected to a public telephone, a home wireless telephone or a wireless private exchange, and performs its function. Therefore, the digital wireless telephone has the same input method as the landline telephone when inputting an area code. In other words, if a user dials a dialing number of the same area, the user should not enter the area code. When dialing a dialing number of another area, the user must dial the area code.

And digital cordless phones offer speed dialing to quickly and easily dial specific dialing numbers when dialing. The speed dial function is a function of dialing only a specific number (hereinafter referred to as a "speed dial number") when dialing again after registering a dialing number and name corresponding to a specific number in a memory.

However, digital cordless telephones use the same area code input method as a landline telephone, so that if the dialing number dialed by the speed dial function has the area code and the other party's area is the same, or if the dialing number does not contain the area code and the other party has different If you are in an area, no currency path is formed. Therefore, if the area code does not match even if the user uses the speed dial function, the user must enter the dialing number again and dial by the general dialing function.

As described above, if the area code is not correct, the user has to feel uncomfortable because the dialing number must be re-entered so that the speed dial cannot perform the basic function.

Accordingly, an object of the present invention is to provide a method for deleting and adding an area code by dividing dialing numbers of the same area and another area when speed dialing.

1 is a block diagram of a digital radiotelephone to which the present invention is applied.

Hereinafter, referring to FIG. 1, first, the controller 10 controls the overall operation. The timer 20 counts and sets various times of the digital radiotelephone. The controller 10 is a ROM for storing a predetermined operating program, a RAM for temporarily storing data generated during the execution of the program, and an electronic program that can be electrically programmed and stores a plurality of parameters. And a memory 11 made up of (EEPROM). In addition, the control unit 10 and the timer 20 are implemented as a one chip microprocessor.

According to the present invention, a speed dial number, a name and a dialing number corresponding to the speed dial number input from the key input unit 12 are stored in the YPIROM of the memory 20 as shown in FIG. 2. The Y pyrom also stores an area code table for reference when deleting the area code of the present invention. Each area code of the area code table is stored in two bytes.

The key input unit 13 includes a plurality of numeric keys and function keys, and applies key data for the keys to the controller 10. The display unit 12 is controlled by the control unit 10, receives and displays display data corresponding to the key data input from the key input unit 13, and displays the operation state and information of the digital radio telephone by icons and text. Display. The signal processor 14 receives predetermined data, demodulates the original signal, and applies the signal to the speaker 15 if the audio signal is input. The signal processor 14 processes a voice signal input from the microphone 16, converts the voice signal into a digital signal, and outputs the digital signal. The signal processor 14 processes the data input from the controller 10 and outputs the data. In addition, the signal processor 14 includes a tone generator, and generates a tone through the buzzer 17 under the control of the controller 10.

The RF unit 30 loads a signal input to the signal processor 14 in a radio signal, converts the received radio signal into data, and applies the signal to the signal processor 14. The RF unit 30 includes a receiver 35, a frequency synthesizer 34, a transmitter 32, and a transceiver 31. The frequency synthesizing unit 34 generates a frequency for designating a transmission / reception channel of the transmitter 32 and the receiver 35 under the control of the controller 10. The transmission and reception separation unit 31 separates the transmitted or received radio signal and transmits the received signal to the antenna 36 and the reception unit 35. The receiver 35 converts the radio signal separated by the transmission / reception separator 31 into a signal processor 14 after performing frequency conversion by filtering and low noise amplification. The transmitter 32 converts a signal input from the signal processor 14 to apply a radio signal to the transceiver 31.

Hereinafter, referring to FIG. 3, the digital wireless telephone switches to the standby state when the power is turned on. In this case, the controller 10 checks whether a call key is input from the key input unit 13 in step 301. In this case, when the call key is input, the controller 10 proceeds to step 303 and checks whether the speed dial mode key is input. If the speed dial mode key is input, the controller 10 proceeds to step 304, and if the speed dial mode key is not input for a predetermined time, proceeds to step 315.

In step 304, the controller 10 sets the speed dial mode, and then proceeds to step 305 to check whether the speed dial number is input from the key input unit 13. In the present invention, the speed dial number is limited to two. However, the speed dial number may be a higher number depending on the memory capacity. When the speed dial number is input, the controller 10 proceeds to step 307, and reads out the dialing number corresponding to the input speed dial number and stores the read dialing number in the RAM. If the dialing number is stored in the RAM, the controller 10 proceeds to step 309 and checks whether the dialing number stored in the RAM has an area code. The presence or absence of the area code is checked by referring to the area code table stored in the Y. pyrom of the memory 11. If it is determined that the area code exists in the area code check, the control unit 10 proceeds to step 311 and deletes the area code, and in step 313 displays the dialing number from which the area code is deleted on the display unit 12. Dial. However, if the speed dial number is not input for a predetermined time in step 305, a general dialing function is executed.

In step 303 to step 315, the controller 10 checks whether the first numeric key is input from the key input unit 13. In this case, when the first numeric key is input from the key input unit 13, the controller 10 proceeds to step 317 and checks whether the first numeric key is pressed for a predetermined period or more. The pressing time of the first numeric key is counted by the timer 20. If the time counted by the timer 20 is equal to or greater than a preset time, the controller 10 recognizes the number corresponding to the first numeric key as a speed dial number, and then proceeds to step 307 described above and after step 307. Execute the same operation as the process of.

In step 317, if the input first numeric key is pressed for a predetermined time or less, the controller 10 proceeds to step 319 to check whether the second numeric key is input. When the second numeric key is input, the control unit 10 proceeds to step 321 to check whether the second numeric key is input for a predetermined time or more. Are recognized as a speed dial number, and the flow proceeds to step 307 described above to execute the same operation as the process after step 307. This is done if the speed dial number consists of two digits. If the capacity of the memory 20 is increased to store more dialing numbers, and three or more speed dial numbers are required, the same process as in steps 319 and 321, that is, a predetermined time of the last digit of the speed dial number. You can add a check to see if it is pressed.

4 is a flowchart illustrating a method for adding an area code in a digital wireless telephone according to an exemplary embodiment of the present invention.

Hereinafter, referring to FIG. 4, the method of adding an area code first checks whether the first numeric key is input from the key input unit 13 in step 401. When the first numeric key is input, the controller 10 checks whether the first numeric key is pressed for a predetermined time or more in step 403. When the first numeric key is pressed for a predetermined time or more, the controller 10 recognizes the number corresponding to the first numeric key as a speed dial number, and proceeds to step 405 to determine a dialing number corresponding to the speed dial number from EPI. Read and save temporarily to RAM. However, if the first numeric key is not pressed for a predetermined time or more in step 403, the controller 10 checks whether the second numeric key is input in step 417. When the second numeric key is input, the controller 10 checks whether the second numeric key is pressed for a predetermined time or more. If the second numeric key is pressed for a predetermined time or more, the controller 10 proceeds to step 405 described above, and performs the same steps after step 405. If the second numeric key is not input in step 417 or if the second numeric key input in step 419 is not pressed for a predetermined time or more, the controller 10 proceeds to step 421 to perform a general dialing function. If the dialing number is stored in the RAM in step 405, the controller 10 checks whether an area code exists in the dialing number in step 407. As a result of the check, if the area code exists, the controller 10 proceeds to step 409 and dials the dialing number using the dialing number. However, if there is no area code in step 407, the controller 10 proceeds to step 411 and displays a message requesting to input an area code through the display unit 12. After displaying the area code input request message, the controller 10 proceeds to step 413 and checks whether the area code is input by the user. If the area code is input in step 413, the control unit 10 proceeds to step 415 and adds and saves the area code to the dialing number stored in the RAM, and then dials the dialing number to which the area code is added in step 409.

On the other hand, if the first numeric key is not input for a predetermined time in step 401, the controller 10 proceeds to step 423 and checks whether the speed dial mode key is input. When the speed dial mode key is input, the controller 10 sets the speed dial mode in step 424 and proceeds to step 425 to check whether a speed dial number is input. If the speed dial number is input in step 425, the controller 10 proceeds to step 427 and checks whether a call key is input from the key input unit 13. When the call key is input, the controller 10 proceeds to step 405 described above, and executes the process of step 415 to step 415 described above.

As described above, the present invention has the advantage of being able to automatically delete and add the area code, so that the caller and the called party can dial using the speed dial function regardless of whether they are in different areas or in the same area.
