(3a), (3b), (3c), (3d) of Figure 3 is an exemplary view showing an example of changing and selecting the character input mode according to an embodiment of the present invention

The present invention relates to a control method for changing a character input mode in a mobile communication terminal. In particular, when changing a mode for inputting a character, a mobile communication terminal which eliminates the hassle of having to input a number of times by selecting a position close to the current position or directly The present invention relates to a control method for changing a text input mode in.

In the early mobile communication terminals, text input was mostly for displaying a user's name or inputting a telephone number. However, with the rapid spread of mobile communication terminals and the diversification of additional functions, mobile communication terminals are capable of information search and text message functions as well as simple call functions. As a result, text input is frequent, and in recent years, a call using a short message service (SMS) in a mobile communication terminal has increased the volume of voice calls. Accordingly, a simple, quick and convenient method of inputting characters has been developed. Types for text input in the mobile communication terminal are characters (a ,,) used as the native language of the user's country and other letters (A, a..) And numbers (0, 1. ..) and special characters (special ..). However, looking at the conventional method for entering characters quickly and conveniently in the following, Korean Laid-Open Patent Publication No. 2002-007852 discloses a plurality of keys in one character input for inputting Korean or English characters having many phonemes on a number substrate. Resolves an issue requiring operation Assignment of characters to 1 to 0 digits on the phone's standard keypad of the Koser mobile phone, and the "*" and "#" keys to simplify the process with shifted function keys, where more efficient In order to do this, a separate shift key was added to allow the user to input characters more quickly. Another method is menu selection by the method of menu selection as disclosed in Korean Patent Laid-Open Publication No. 2002-93361, and when a character is input, a similar character corresponding to the character is displayed so that there is no more character input or minimal character. There is also a simple way to enter an additional to select the menu. The prior art only helps when directly inputting a character, and when the change is made according to various character input modes, the number of times of pressing is also increased, and thus, the effect of reducing the number of pressing times is not very helpful. Korean Patent Laid-Open No. 2003-50582 is a method of inputting after changing a character input mode when inputting a character. This method changes the input mode by using the time when the key is pressed and the shift key in changing the character input mode when inputting letters, numbers, and special symbols to minimize the number of key presses when inputting characters as a whole. This is how you can. In this case, however, since the designated key needs to be pressed for a predetermined time, the number of times can be reduced, but there is a problem in that the input time increases as a whole. Another conventional example is a method of using a menu key when changing a text input mode for letters, numbers, and special symbols. When it is displayed for selecting letters, numbers and special symbols, each time the menu key is pressed, it is shifted in one direction to select the input mode of the corresponding letter. In this case, since the character input mode is selected to move in one direction, when the character input mode in the reverse direction is selected, all or several menu keys must be pressed. Character input speed is slow.

Accordingly, an object of the present invention is to provide a method for quickly and conveniently selecting a text input mode in a mobile communication terminal.

Another object of the present invention is to provide a method for freely selecting left or right when selecting a different character input mode at a current position of a character input mode in a mobile communication terminal.

Still another object of the present invention is to provide a method for directly selecting by one or more keys simultaneously pressed when selecting a character input mode.

The present invention for achieving the above object is a first process of identifying the current reference point in the character input mode;

A second step of checking whether there is a key input for changing the character input mode from the reference point;

A third step of confirming whether the key for changing the character input mode is moved to the left and is a key for selection or moving to the right to select a key;

A fourth step of selecting a corresponding character input mode by moving according to a left or right change key input in the third step;

Left from the reference point in the third step. It is not for selecting the character input mode on the right side, but it is composed of a fourth process of directly selecting a corresponding character input mode when one or more keys are simultaneously input.

Hereinafter, with reference to the accompanying drawings in the detailed description of the operating principle of the preferred embodiment of the present invention, if it is determined that the detailed description of the known function or configuration may unnecessarily obscure the subject matter of the present invention. Omit.

1 is an internal circuit diagram of a mobile communication terminal according to an embodiment of the present invention.

The RF unit 123 performs a wireless communication function of the mobile communication terminal device, and the data processor 120 demodulates and decodes the transmitter and the received signal that encodes and modulates the transmitted signal. The audio processor 125 reproduces the received audio signal or outputs a transmission audio signal generated from the microphone. Since these parts are not directly related to the present invention, further description is omitted.

The memory 130 may be composed of program memory and data memories. The program memory may store programs for controlling a general operation of a mobile communication terminal device and programs for changing a text input mode for an embodiment of the present invention. In addition, the data memory temporarily stores data generated during the execution of the programs.

The controller 110 performs a function of controlling the overall operation of the mobile communication terminal device. In particular, in accordance with the present invention, the controller 110 controls the display unit 160 to display the state of the character input mode, checks the current reference point of the character input mode, and moves to the left from the reference point according to a key input. Move to the right to control to change the character input mode to select the corresponding character input mode or to select the corresponding character input mode when more than one key is input at the same time.

The display unit 160 controls the key input from the key input unit 127 in the control unit 110 to display the state of the character input mode and an example of the change.

The key input unit 127 includes keys for inputting numeric and character information and function keys for setting various functions. The keys used in the embodiment of the present invention are the * key and the # key. Use the * key to move to the left from the current reference point and use the # key to move to the right to control other character input modes.

In the key input unit 127, one or more keys are directly selected when inputted. That is, when the " 1 " key and " * " are input at the same time, the controller 110 allows the Hangul to be directly selected from the character input mode.

2 is a flowchart for changing a text input mode according to an embodiment of the present invention.

After the character mode is selected in the current in the character input mode is set to the reference point - to enter the key or the side eopki moved to the left from the reference point to set up the other text input mode, and enter the # key or the side down key from the reference point Move to the right and select another character input mode. Accordingly, in the same manner as above, the character input mode is selected according to the rotation of the left and right sides according to the input of the *, # key or the side up and down keys. And if you enter * key and number ( 1,2,3 ...) at the same time, you can select another character input mode directly.

3 is an exemplary diagram illustrating an example of changing and selecting a character input mode according to an embodiment of the present invention.

(3a) is an example showing the current reference point of the initial character input mode,

(3b) is an example of shifting to the left by * or the side up key,

(3c) shows an example of moving to the right by the # or the side down key.

(3d) is an example of directly selecting the character input mode by simultaneously pressing the * key and the numeric keys ( 1,2,3,4 ....).

Therefore, when the embodiment of the present invention will be described in detail with reference to FIGS.

In text entry mode types are the Hangul mode (eg, a), uppercase letter mode (eg, A), lowercase letters mode (eg, a), the special character mode (ie, special), numeric mode (for example, 1) , Are shown in the example at the bottom of FIG. In order to select the required character input mode, the key for the character input mode is input in step 201 from the input of the menu key in the key input unit 127, and in step 203, the controller 110 checks whether it is correct. If the character input mode is in the above process, the display unit 160 displays " A, A, A, 1 " as shown in the example (205). The current reference point is set in step 207 to determine which input mode was previously or automatically entered. Here, the reference point is set to the initial position by default when the character input mode is selected, but the character input mode used previously may be set as the reference point. If it is set to " a " as shown in (3a) of Fig. 3, the excitation is a reference point. Starting from this reference point, the present invention enables the user to quickly and easily select a desired input mode while moving to the left or right according to a key input. In step (209), if there is a key input for the character type, that is, the desired input mode, it is checked in (211, 213, 217, 219) whether it corresponds to the * or # key and the side up / down key. For example, if you want to select the capital letter (A) as shown in (3a) to (3b) of FIG. 3 in step (209), press * or the side up key in the key input unit 127 to confirm in step (211,213). In step 215, the user moves to the left from the reference and selects the uppercase alphabet (A). However, if you want to select a special character ( especially ) as shown in (3a) to (3c) of Figure 3 in the step (209), pressing # or the side down key in the key input unit 127 is confirmed in (217,219) ( In step 221, the user moves to the right from the reference and selects a special character (special). Meanwhile, instead of sequentially moving left or right as in the example of (3a) to (3b) or (3c) of FIG. 3 in step (209), the character input mode is directly applied as in the example of (3d). If you want to make a selection, press the * key and the number ( 1,2,3,4... Key) at the same time ( * + 1 = Korean, * + 2 = English lowercase .....) 3, the input character mode is directly selected as in the example of 3d of FIG. In the process of steps 215, 221, and 225, the process is repeated until there is no key input for selecting the character input mode in step 229, and the process is repeated.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.

As described above, the present invention can freely select left or right when selecting a different character input mode at the current position of the character input mode in the mobile communication terminal, and can be directly selected by one or more keys simultaneously pressed. There is an advantage to doing.
