The present invention relates to a mobile communication terminal equipped with a Hangul input function using a motion detection sensor set by using a motion of the controller and a control method thereof.

In general, a personal mobile communication terminal such as a cellular phone or a PDA carries various types of digital wireless communication using 2GHz band radio waves while carrying one small portable terminal (about 100 ~ 150g) each person. Refers to a service system that performs. However, this definition of the personal mobile communication terminal as described above refers to a concept that is independent of the technology or system used. By utilizing various technologies and network systems through liberalization and competition, the general public has no difference from landline phones. At low prices, it allows mobile communication, especially in the city center or suburbs, and to communicate with a person's unique number rather than the number associated with a place or vehicle such as a house or office. However, recently, a complex digital technology is incorporated into such a mobile communication terminal system, and its function is rapidly enlarged, and a key panel part or a keyboard including a control button or a text input function of a complicated structure is usually used to precisely control it according to the installed specification.

A mobile communication terminal 71, 72 for executing a function; a base station system 73 for wirelessly processing function signals transmitted from a plurality of terminals 71, 72, such as call signals and SMS messages, as described above; An MSC 74 that controls a transmission function of a call signal or SMS message input through the base station system 73, and an SMS message center connected to the MSC 74 to provide an SMS message to the terminal 71; 75).

As shown in FIG. 2, the keypad unit 70 of the terminal 71 includes a function button 76 and a character button 77 to which Korean consonants and vowels are assigned, together with numbers, vertically in three rows. It is composed.

On the other hand, looking at the operation of the conventional mobile communication terminal as described above, if the user of the terminal 71 wants to transmit the information desired by the user, for example, to the other terminal in the SMS message, the user of the terminal 71 is a terminal ( Through the menu function key 76 of the keypad 70 of 71, the corresponding menu displayed on the LCD panel 78 is selected, and the required character is input by operating the character button 77. For example, if the message to be written is "Send", first press button 7 assigned with consonant "ㅈ", then press button 3 assigned with consonant "ㅓ", and then press button 2 assigned with consonant "B". Press to complete the Hangul "jeon" character.

Therefore, if a user wants to erase a certain letter by writing a message in a manner as described above, the terminal user deletes letters one by one using the erase key of the keypad 70 and then rewrites them. When the text input is completed through the above process, the user of the terminal 71 presses a transmission button together with the destination telephone number. Then, the terminal 71 transmits the text data input by the current user to the SMS message.

Therefore, the SMS message signal of the terminal 71 is input to the SMS message center 75 via the base station system 73 and the MSC 74 and stored. The SMS message center 75 checks the destination telephone number of the input SMS message and transmits it to the MSC 74. Then, the MSC 74 transmits the SMS message signal transmitted from the SMS message center 75 to the counterpart mobile phone 72. The counterpart terminal 72 analyzes the received SMS message signal and displays the signal on the display.

However, since the keypad device of the conventional mobile communication terminal as described above is a method in which all Korean consonants and vowels are assigned together in a single button, the terminal user often mistypes the text message when writing a text message. Convenience was considerably deteriorated, and because the numbers, Hangul consonants, and vowels were combined with each other, there was a problem in that the space utilization of the keypad was significantly reduced when the number of keys increased.

Accordingly, the present invention has been invented to solve the above problems, since only the Korean consonants are arranged on the keypad and the vowels are processed through the motion detection sensor, the terminal user can intuitively input the Hangul using keys. Therefore, the purpose of the present invention is to provide a mobile communication terminal equipped with a Hangul input function using a motion detection sensor that can maximize the usability of the terminal and a control method thereof.

In this case, when the character input intended by the user is not input through the key panel unit or the motion detection sensor, the process returns to the character menu screen execution step S4 and repeats the loop. However, if the character intended by the user is input through the key panel unit or the motion detection sensor as a result of checking during the character input checking step (S5), the process proceeds to the text message configuration step (S6) and the consonant signal and operation of the input key panel unit. Combining the vowel signal by the detection sensor to form characters and display them on the display.

In other words, when the user of the terminal 1 wants to transmit or store information desired by the user, for example, a text message in an SMS message to another terminal, the user of the terminal 1 may use a key panel of the terminal 1. The menu displayed on the display 2 is selected and executed by the menu function key (not shown) of the unit 3. In addition, the terminal user inputs a character intended by the user through the movement of the key panel unit 3 and the terminal 1. In this case, the Hangul consonant is input through the key panel unit 3. ), The vowels are entered individually.

For example, if the message to be written is "transmit", first press the button of the key panel unit 3 to which the consonant "ㅈ" is assigned, and then the vowel "ㅓ" tilts the terminal to the left once and then the Press the button assigned to "b". Then, the main control unit 5 of the terminal 1 displays the "all" character by synthesizing the vowel "ㅓ" through the motion detection sensor 4 which detected the terminal movement in addition to the consonants which the user inputs sequentially. Mark).

Then, the terminal user again presses the button of the key panel unit 3 to which the consonant "s" is assigned, and then tilts the terminal upward once, and assigns it to "o" of the key panel unit 3. When the button is pressed, the main control unit 5 of the terminal 1 sequentially synthesizes the vowel “ㅗ” through the motion detection sensor 4 which detects the movement of the terminal in addition to the consonants inputted by the user. It is displayed on the display 2. Thus, when the consonants and the vowels are synthesized as described above, the word "transfer" is completed.

Therefore, according to the present invention as described above, the Hangul character input can be easily realized.
