The present invention relates to a method of inputting an English letter in a mobile communication terminal, and more particularly, to a method of specifying a basic key and a legend key to simplify character input.

Recently, the increase in the use of the Internet and mail using the mobile terminal has increased the input of the alphabet.

1 is a block diagram showing an internal configuration regarding key input in such a mobile communication terminal. As shown, a central processor (1) for controlling the system of the mobile communication terminal, and a key input unit (2) composed of a plurality of keys, such as a screen switching key, a numeric key and an input completion key to allow a user to enter a key And the central processor 1, the key input unit 2, the liquid crystal display 3, and a memory 4 storing English fonts.

In the general mobile communication terminal configured as described above, when a user inputs a number or English through the key input unit 2, the central processor 1 processes the input key value and displays the input number on the screen 3 as it is. The input English letter is searched for the key value input using the English font embedded in the English font memory 4, and is converted into an English letter code by the English input key and displayed on the liquid crystal display 3.

Unlike other keyboards, KEY PAD of currently used mobile communication terminal is limited by space, and in general, two 'Q', 'Z' are used for number 1 key, and 'Q', 'from 2'. It is a form of three 24 letters except Z '.

Alphabetical order is listed regardless of frequency, consonant, vowel order except 'Q', 'Z', and it should be pressed up to three times to input English letters arranged in one numeric key.

As shown in Fig. 2 and Fig. 3, the content of assigning an English letter to a numeric key is as follows.

'Q', 'Z', '.'

'A', 'B', 'C' in number key 2

'D', 'E', 'F' on numeric key 3

'G', 'H', 'I'

'J', 'K', 'L' on the numeric key 5

'M', 'N', 'O' in number key 6

'P', 'R', 'S' in numeric key 7

'T', 'U', 'V'

'W', 'X', 'Y'

On the other hand, in the case of Figure 4, only the numeric key 1 and the numeric key 0 are as follows, the rest is the same as the key arrangement.

'＠', 'Q', 'Z'

On numeric key 0 ' . ',' , ','? ','! '

In the case of FIG. 3, there are two types of Korean input mode and English input mode. In English input mode, up to English case and numbers may be input. Therefore, input mode selection is simple, but it assigns a total of seven letters such as three English uppercase letters, three lowercase letters, and one number to one numeric key, and you have to press the maximum seven times until the desired letter or number appears.                         

In the case of FIG. 4, four modes are set: a Korean input mode, a numeric input mode, an English uppercase input mode, and a lowercase input mode. Therefore, to input English, numbers, or Korean, press the function key for setting the mode several times and press until the desired mode is displayed, and then repeatedly input the number key corresponding to the character to be input.

However, in the above case, since there are several input modes, several key inputs are required to select the input mode to be used.

For example, assuming that the order of the input modes is Korean → English lowercase letters → English uppercase letters → numbers, and the word that the user wants to input is 'Silicone TOP 10',

Press the function key twice to switch the input mode to English capital letters.

To enter the letter 'S' three times, press the numeric key 7 three times.

Press the function key 4 times to change the input mode to lowercase English.

To enter the letter 'i', press the number 4 key three times.

To enter the letter 'l' three times, press the numeric key 5 three times.

To enter the letter 'i', press the number 4 key three times.

To enter the letter 'c', press the number 2 key three times.

To enter the letter 'o', press the numeric key 6 three times.

Press the numeric key 6 twice to enter the letter 'n',

Press the function key once to change the input mode to English capital letters.                         

To enter the letter 'T' once, use the numeric key 8 once.

To enter the letter 'O', press the numeric key 6 three times.

To enter the letter 'P' once, use the numeric keys 7

Press the function key once to switch to numeric input mode.

Press numeric key 1 once to enter number '1',

In order to input the number '0', the numeric key 0 must be entered once, so a total of 36 keystrokes must be made. That is, it is inconvenient to frequently press a function key to switch to each input mode.

In addition, in the case of Figure 3 input mode is Korean and English,

Press the function key once to switch to English input mode.

To enter the letter 'S' 7 times,

To enter the letter 'i', press the number 4 key three times.

To enter the letter 'l' three times, press the numeric key 5 three times.

To enter the letter 'i', press the number 4 key three times.

To enter the letter 'c', press the number 2 key three times.

To enter the letter 'o', press the numeric key 6 three times.

Press the numeric key 6 twice to enter the letter 'n',

To enter the letter 'T', press the numeric key 8 five times.

To enter the letter 'O', press the number key 6 seven times.

To enter the letter 'P' four times, use the numeric keys 7                         

To enter the number '1', press the numeric key 1 three times.

In order to input the number '0', the number key 0 must be entered 46 times in total.

In the above case, the number of pressing the function key is small, but there is a problem that the user must repeatedly input four or more times in order to input a number or capital letters.

In addition, the biggest problem with the two methods of the key input is the frequency of use of the letters. As shown in FIG. 7, most frequently assigned letters are assigned to the second and third.

That is, the letters with a frequency of more than 5% are 9 characters such as A, E, H, I, O, N, R, S, T, among which the letters except A and T are placed in the second and third You can see that.

This is the most decisive factor in increasing the number of times when entering characters.

The present invention has been made in order to solve the above problems, and the purpose is to simplify the character input by setting a character with a high frequency of use when inputting English characters in the mobile communication terminal, and the rest as a legend key .

According to the present invention for achieving the above object, in the method for inputting English characters using a wireless terminal, assign a character with a high frequency of use as a basic character key, and assigns buttons other than the character key as a legend key, By inputting English characters in combination with and the legend key, the basic characters can be input by one button touch, and the other characters can be input by pressing the legend key once more.                     

In addition, the present invention, the basic character key is assigned to each of the numeric keys, including the basic character, Q, A, E, I, L, O, R, T, Y with a high frequency of use, as the basic character and,

The legend key is assigned to a * button, a # button, a volume up / down button, and a recording button so that a character other than the basic character is inputted by pressing a corresponding numeric key and a preset legend key, respectively.

In another aspect, the present invention is characterized by setting the volume UP key of the wireless terminal to an English / English conversion key, pressing the volume UP key to set the English / English conversion mode, and then inputting a character.
