Converts the digital signal received by the modulator / demodulator 101 to modulate the digital voice signal, the data compressor 102 to compress the input digital voice signal, and the RF / IF processor 100 into a voice signal, or A codec 105 for converting an audio signal input through the microphone 111 into a digital signal, a DTMF generator 104 for generating a dual tone multi frequency (DTMF) tone generated when a key button is pressed, and an entire system A main processor 103 for performing a call processing protocol for controlling and connecting calls, an audio amplifier 106 for amplifying analog signals input from the codec 105 or the microphone 111, and a speaker ( 110) and microphone (111) A liquid crystal display 107 for outputting the state of the terminal, a memory 108 for storing information of the terminal such as programs and variables used in the main processor 103 and a telephone number, and a keypad 109 which is a user interface. It consists of.

The transmission / reception operation of the mobile terminal configured in this way will be described next.

First, when the transmission operation is described, when the user inputs a voice signal by hooking off the hook, the microphone 111 converts the voice signal into an electrical signal and transmits it to the codec 105.

The codec 105 samples the analog voice signal received from the microphone 111, converts the signal into a PCM signal, and transmits the same to the data compressor 102. The data compressor 102 transmits the PCM signal transmitted from the codec 105. Compress.

The main processor 103 then multiplies the compressed PCM signal by the PN code, and the modulator / demodulator 101 modulates the spread PCM signal for transmission to the radio section. Subsequently, the RF / IF processing unit 100 up-converts the voice signal of the intermediate frequency input from the modulator / demodulator 101 into a high frequency band and then transmits the signal through an antenna.

Since the reception operation is the inverse of the transmission operation, description thereof is omitted.

The mobile terminal described so far stores information such as a phone book, an address book, and schedule management in the memory 108. And it supports PC_Sync function to change and add this information more conveniently. Here, the PC_Sync function refers to changing or adding information stored in the mobile terminal using a computer.

Therefore, when the user wants to change or add the information of the terminal using the PC_Sync function, first, the computer and the mobile terminal are connected with a dedicated cable, and then the information of the mobile terminal is changed or added through the computer.

However, considering the PC-Sync function of the conventional mobile terminal, a PC-Sync dedicated cable must be provided for connecting the computer and the mobile terminal, and a PC-Sync dedicated program must be installed in the computer to perform the PC_Sync function. do. Therefore, the PC_Sync function of the conventional mobile terminal is inconvenient to use.

Accordingly, an object of the present invention is to provide a data updating method of a mobile terminal that performs a PC-Sync function without adding hardware, in view of the above-described problems of the prior art.

According to one aspect of the present invention for achieving the above object, the data update method of the mobile terminal is a first step of the mobile terminal to set the data update destination mode, and a call request from the computer to the mobile terminal; A second step, a third step of setting up a call between the mobile terminal and the computer according to the request, and a step of informing the computer that the mobile terminal is set to a data update destination mode as the call is set. And a fifth step of changing or adding data stored in the mobile terminal through the set call in the computer.

Preferably, the computer requests the mobile terminal to establish a data call using a communication emulator.

Hereinafter, a configuration and an operation according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

The present invention proposes a data update method of a mobile terminal which performs a PC_Sync function without using a PC_Sync dedicated cable and a PC_Sync dedicated program.

To this end, the present invention sets up a data call between the computer and the mobile terminal, and performs the PC_Sync function using the data communication function of the mobile terminal through the set data call. In this case, it is assumed that software for supporting the data communication function and the PC_Sync function is already installed in the mobile terminal.

On the other hand, it is assumed that the computer is provided with a modem, and establishes a data call with the mobile terminal using a communication emulator.

2 is a flowchart illustrating a data update method of a mobile terminal according to the present invention.

Referring to FIG. 2, first, the mobile terminal is set to the PC_Sync incoming mode (S200).

Subsequently, when the mobile terminal is set to the PC_Sync incoming mode, the mobile terminal attempts to establish a data call to the mobile terminal using a computer on which a modem is installed (S201). At this time, the computer attempts to establish a data call to the mobile terminal using an emulator for communication (for example, hyper terminal, Sarom Dataman Pro, etc.).

Thereafter, when a data call is set up between the computer and the mobile terminal, the mobile terminal transmits data for notifying that it is setting the PC_Sync function to the computer (S202 and S203).

The computer outputs a message indicating that the data call is set up with the mobile terminal and a message indicating that the mobile terminal is set to PC_Sync.

Therefore, the user performs a PC_Sync function of changing or adding data output through the computer (S204). At this time, the mobile terminal provides a data read function, an data add function, and a data change function to the computer so that the PC_Sync function is performed.

For example, when the computer reads information, the user inputs 'L' through the computer's communication emulator. The mobile terminal then outputs the contents stored in the memory in a predetermined number of units.

In addition, when the computer adds or changes information, the user inputs 'M N P' through the computer's communication emulator. 'M' is the address of the memory, 'N' is the name of the person to be stored, and 'P' is the information to be stored. Therefore, if you enter '5 Honggil-dong 019123xxxx' on the computer, Honggil-dong and the corresponding number are stored in the fifth memory. If you enter the memory address being used here, the newly entered contents are stored in the memory address.

On the other hand, the present invention has been described in the embodiment of updating the data of the telephone book of the contents stored in the memory.

3A to 3B illustrate a liquid crystal display of a mobile terminal when the PC_Sync incoming mode is set.

3A to 3B, the PC_Sync incoming mode according to the present invention is further configured in the data communication setting menu. This PC_Sync incoming mode is set in advance before the PC_Sync function is executed when the PC_Sync function is performed through a data call connection with a computer.

4A through 4E illustrate messages output to a computer executing a wireless PC_Sync function.

4A to 4E, when a user attempts to make a data call with a mobile terminal to which a user wants to connect using a communication emulator of a computer, the monitor of the computer may connect a data call with the mobile terminal and the PC_Sync function of the mobile terminal. A message indicating whether or not to set is displayed.

The data of the phone book stored in the memory of the mobile terminal is output.

The user then sends a command to the mobile terminal to change the data in the phone book output through the communication emulator or add new data.

As described above, according to the data update method of the mobile terminal according to the present invention, since the PC_Sync function can be executed using the line data service even without a dedicated cable and a PC_Sync dedicated program for connecting the computer and the mobile terminal, the PC_Sync function is conveniently performed. It can be used.
