BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal and a method of operating the same, and more particularly, to a mobile communication terminal having a character key embedded separately from a numeric key and a method of operating the same.

In general, the mobile communication terminal functions as a text transmission / reception function as well as a voice call function, and is provided with a key input unit for inputting a telephone number or a text message (SMS).

1 is a perspective view of an example of a mobile communication terminal according to the prior art.

As shown in FIG. 1, the mobile communication terminal 1 according to the related art is provided with a main body 6 including a rear casing 2 and a front casing 4, and a plurality of numbers installed on the front casing 4. It comprises a key pad 20 in which a key 18 is formed.

The front casing 4 is formed with opening holes 5 slightly larger than each of the keys 18.

The front casing 4 is provided with a talker 10.

The front casing 4 is provided with a rotatable or slidable sub body 12 that covers the front surface of the front casing 4 when the mobile communication terminal 1 is not in use.

The sub body 12 is provided with a display 13 and a receiver 14.

In each of the numeric keys 18 of the keypad 20, not only numbers for voice calls but also English alphabets or Korean consonants / vowels for text transmission are provided by printing or the like.

Reference numeral 15 is a battery detachably mounted on the rear surface of the rear casing 4.

Reference numeral 16 is an antenna provided on the upper surface of the rear casing 4.

However, the conventional mobile communication terminal combines the words or syllables because the English alphabets assigned to the numeric keys 18 or the Korean consonants / vowels are combined to form words or syllables in order to transmit text messages (SMS). There is a problem that takes a considerable time.

On the other hand, in order to solve the above problems, when provided with a separate character keypad on the side, top, bottom of the numeric keys 18 of the front casing (4), the size of the entire mobile communication terminal (1) There is a problem that the portability is increased.

In addition, since conventional mobile communication terminals have different arrangements of Korean consonants / vowels for each manufacturer or terminal, a user who purchases a new mobile communication terminal is unfamiliar with the character combination of the new mobile communication terminal and is inconvenient to transmit a text message. There is a problem that you feel.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the prior art, and has an object of the present invention to provide a mobile communication terminal capable of more quickly combining / transmitting characters while minimizing the size of the mobile communication terminal.
