The present invention relates to a mobile communication terminal equipped with a duplicated character delete button and a control method thereof. Particularly, a single character delete button implements a backspace key function and a delete key function at the same time to delete a previous character or delete a back sentence. The present invention relates to a mobile communication terminal having a duplicated text delete button that is executed immediately without moving and a control method thereof.

In general, wireless data communication refers to a communication function of wirelessly transmitting and receiving various data such as letters, numbers, and images through a base station system using a portable terminal capable of wireless transmission and reception. For example, it is a mobile communication system for exchanging or searching data in both directions while moving by using various terminals such as a cellular phone, a portable computer, a facsimile, and a credit card inquiry machine.

Such a mobile communication system is rapidly growing due to the first commercialization of a cellular-phone that uses the same frequency channel repeatedly in a cell geographically separated from North America and implements a radio channel switching function between cells according to a subscriber's movement. It became. In recent years, however, the universal mobile telecommunication system is capable of transmitting "third generation", broadband packet-based text, digitized voice or video, and multimedia data at a high speed of 2 Mbps or higher, regardless of where the mobile or computer users are anywhere in the world. Networks are developed to provide consistent services.

Then, the conventional mobile communication terminal as described above with reference to Figure 1, the base station 71 for wirelessly processing function signals, for example, call signals or SMS messages transmitted from a plurality of terminals (70, 76), and And an MSC 72 for processing call signals input via the base station 71.

Here, a part of the body of the terminal 70 has an LCD panel 73 for displaying a function operated in the terminal 70 to the outside or an information search function set by the user while waiting, for example, a photo album screen. It is provided. And, on the keypad 74 of the terminal 70 is provided with a character delete button (CLR KEY) for deleting a character.

On the other hand, referring to the operation of the conventional mobile communication system as described above, when the user of the terminal 70, for example, wants to send an SMS message, the user of the terminal 70 is the keypad 74 and the keypad of the terminal 70 After selecting the menu using the button of (74), the necessary characters are inputted. In this case, if it is necessary to correct the input characters, move the cursor located on the LCD panel 73 one space at a time and then delete the character. Press (77: CLR KEY) to edit.

When the character input is completed through the above process, the user of the terminal 70 selects a destination telephone number to be transmitted from a list of phone books stored therein and presses the transmit button. Then, the terminal 70 transmits the text data input by the user in the SMS message to the base station 71. Accordingly, the SMS message signal of the terminal 70 is input to and stored in the SMS message center 75 via the base station 71 and the MSC 72. Then, the SMS message center 75 checks the destination phone number of the input SMS message and transmits it to the MSC 72. Then, the MSC 72 transmits the SMS message signal transmitted from the SMS message center 75 to the counterpart mobile phone 76. The counterpart terminal 76 analyzes the received SMS message signal and displays the signal on the display.

However, the conventional mobile communication terminal as described above moves to the front position of the corresponding character by using the cursor key to delete the character and then deletes it by using the character delete button (CLR KEY) or the character delete button is composed of the backspace key. If the user moves the cursor to the back of the character to delete and then deletes it differently depending on the manufacturer, it is very inconvenient for the terminal user. Also, the character delete button works only with one delete function. Since the key user is not accustomed to using the character delete button, there is a problem that the usability of the terminal is considerably reduced.

Accordingly, the present invention was invented to solve the above-mentioned conventional problems, and implements the backspace key function and the delete key function at the same time in one character deletion button to immediately perform the deletion of the previous character or the deletion of the back sentence without moving the cursor. An object of the present invention is to provide a mobile communication terminal having a duplicated text delete button and a control method thereof.

Another object of the present invention is a user who is familiar with the keyboard keyboard of the computer can be easily deleted through the double character delete button, so that the functionality of the terminal is also significantly improved mobile terminal with a duplicated character delete button and control method thereof To provide.

The present invention for achieving the above object is provided in the body of the mobile communication terminal performing a call processing function, the left arrow and the back button (back-space) function to perform a delete button function A key panel unit having a double CLR key composed of a double pressing structure of a right arrow, and recognizing the separated pressing operation of the double CLR key, the cursor located on the LCD panel unit is moved to the front and rear positions according to the corresponding function. The present invention provides a mobile communication terminal having a duplicated text delete button including an MSM unit for controlling overall functions of the communication terminal.

Another feature of the present invention is the right arrow key setting confirmation step of confirming whether the current terminal user pressed the right arrow portion of the double CLR key during document creation when a character to be deleted during document creation of the mobile communication terminal, and the right arrow When the right arrow of the double CLR key is pressed as a result of the key setting checking step, the delete pressing step of immediately deleting the character behind the cursor and the character of the current terminal when the character to be deleted during the writing of the mobile terminal are generated. When checking the left arrow key setting step to check whether the left arrow part of the double CLR key is pressed during the writing and the left arrow key setting checking step, the terminal user presses the left arrow part of the double CLR key while writing the document. Space to delete the character immediately before the cursor The redundant text delete button made of a face feature execution step provides a control method of the mobile communication terminal.

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

The apparatus of the present invention is provided with a double CLR key (1) consisting of a double pressing structure of a left arrow having a back-space function and a right arrow having a delete button function as shown in FIG. Recognizing the separated pressing operation of the key panel unit 2 for inputting a signal and the dual CLR key 1, the cursor located on the LCD panel unit 3 is moved to the front and rear positions according to the corresponding function. A mobile station modem (MSM) unit for controlling overall functions of the communication terminal 4 and an analog voice input through the handset 6 according to a call connection control signal of the MSM unit 5. And a codec unit 7 for converting a signal into a digital signal or converting a digital voice signal into an analog signal and outputting the analog signal.

One end of the MSM unit 5 is connected to a memory unit 8 that stores various types of information of the mobile communication terminal 1.

Next, the operation and effects of the present invention as described above will be described.

The method of the present invention first proceeds from the terminal initialization step S1 to the document creation function setting confirmation step S2 as shown in FIG. 3 to check whether the document creation function is currently set in the terminal. At this time, when it is confirmed by the document creation function setting confirmation step (S2) that the document creation function is not currently set in the terminal, the process proceeds to the general call processing execution step (S3) to execute the normal terminal call processing operation.

That is, when power is applied to the terminal 1 of the present invention, the MSM unit 5 of the terminal 1 proceeds to an initialization state, forms necessary information from the internal memory unit 8, and reads each parameter. In addition, the MSM unit 5 of the terminal 1 executes an initialization process and then receives information necessary for the system including time information through a pilot channel and a sync channel transmitted from the base station system unit 9, and then waits. Proceed to

At this time, the MSM unit 5 of the terminal 1 recognizes when the user inputs a telephone number through the key panel unit 2 and presses a call button, and the user inputs the telephone number to the memory unit 8. In addition to the storage, the system accesses the base station system unit 9 through the access channel, and then transmits an outgoing signal to the corresponding telephone number. Then, the base station system unit 9 processes the outgoing signal sent from the terminal 1 and transmits an incoming call to the counterpart terminal 10 to form a call. That is, when a user of the terminal 1 inputs a voice signal through the handset 6, the codec unit 7 of the terminal 1 signals the voice signal input through the handset 6. The process is input to the MSM unit 5. The MSM unit 5 of the terminal 1 wirelessly processes the voice signal input through the codec unit 7 and transmits the voice signal to the counterpart terminal 10 via the base station system unit 9 so that a normal call can be made. Is achieved.

However, when it is confirmed by the document creation function setting confirmation step (S2) that the document creation function is currently set in the terminal, the process proceeds to the document creation menu execution step (S4) to execute the document creation menu on the LCD panel. After the document creation menu execution step (S4), proceed to the right arrow key setting confirmation step (S5) to check whether the current terminal user pressed the right arrow portion of the double CLR key during document creation. At this time, when the right arrow key setting confirmation step (S5) is confirmed, if the right arrow portion of the double CLR key is pressed, the process proceeds to the delete pressing step (S6) and immediately deletes the character behind the cursor. However, as a result of checking during the right arrow key setting check step (S5), if the right arrow portion of the double CLR key is not pressed, the process proceeds to the left arrow key setting check step (S7) and the current terminal user is writing a double CLR key while writing a document. Make sure you press the left arrow of the button. Here, as a result of checking during the left arrow key setting checking step (S7), if the current terminal user does not press the left arrow portion of the double CLR key while writing the document, the current step ends and proceeds to the standby state.

However, as a result of checking during the left arrow key setting confirmation step (S7), if the current terminal user presses the left arrow part of the double CLR key while writing the document, the process proceeds to the backspace function execution step (S8) and the cursor forwards to the backspace function. Delete the text immediately.

That is, when it is confirmed that the document creation function is set in the mobile communication terminal 4, the MSM unit 5 executes the document creation menu on the LCD panel 3. If you want to erase a certain letter during the writing process as described above and want to erase it, you can press the double CLR key (1) according to the position of the cursor. At this time, when the cursor of the LCD panel 3 is located in front of the letters to be erased, the right arrow of the double CLR key 1 may be pressed. On the other hand, if the cursor of the LCD panel unit 3 is located behind the character to be erased, press the left arrow of the double CLR key (1), and the MSM unit (5) immediately returns the character of the cursor with the backspace function. Delete it.

Therefore, the dual CLR key of the present invention uses both the delete function and the backspace function.

As described above, the present invention implements the backspace key function and the delete key function simultaneously in one character delete button to immediately perform the deletion of the previous character or the sentence delete without moving the cursor, thereby maximizing the editability of the terminal sentence. It has the advantage of letting.                     

In addition, according to the present invention, a user familiar with the keyboard of the computer can be easily deleted through the double character delete button, thereby improving the functionality of the terminal.
