In this case, the term '~ part' used in the present embodiment refers to software or a hardware component such as an FPGA or an ASIC, and '~ part' performs certain roles. However, '~' is not meant to be limited to software or hardware. '~ Portion' may be configured to be in an addressable storage medium or may be configured to play one or more processors. Thus, as an example, '~' means components such as software components, object-oriented software components, class components, and task components, and processes, functions, properties, procedures, and the like. Subroutines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functionality provided within the components and the 'parts' may be combined into a smaller number of components and the 'parts' or further separated into additional components and the 'parts'.

The input unit 110 receives a key signal generated by the input device 300 of the mobile communication terminal 100 selected by the user.

The determination unit 120 determines a key signal input through the input unit 110. Here, the input key signal may be understood as a consonant key signal, a vowel key signal, an upper pair key signal, a lower pair key signal, and a special function key signal (for example, menu selection).

For example, the determination unit 120 determines whether the key signal input through the input unit 110 is the upper pair key or the lower pair key signal. As a result of the determination, in the case of the upper pair key or the lower pair key signal, after determining whether a specific consonant key signal is input by the user, the controller 160 determines whether the upper pair key or the lower pair key is selected and information on the input consonant key. By transmitting the corresponding character is generated through the character generation unit 130.

If, as a result of the determination, the input key signal is not the upper pair key or the lower pair key signal, the determination unit 120 provides the determination result to the controller 160 so that the corresponding character (consonant or vowel) is the character generator 130. It can be created directly through.

The character generator 130 generates a corresponding character by combining consonants and vowels assigned to a key selected by the user based on the determination result of the determination unit 120. Here, when the upper pair key or the lower pair key signal is input, the character generator 120 changes the corresponding consonant to a twin consonant or a consonant consonant to generate a character.

For example, when the character generator 130 determines that the input key signal is the upper pair key or the lower pair key signal as a result of the determination by the determination unit 120, the initial character or finality of the terminal sound assigned to the consonant key input from the user is determined. The consonant is changed to a consonant, and a corresponding character is generated based on the changed consonant and the vowel key signal input from the user.

The storage unit 140 stores location information of consonants, vowels, upper pairs, and lower pairs assigned to each key of the input device 300. In addition, the storage 140 stores an operation program and a system program of the controller 160. Here, the operating program or the system program is usually stored in the ROM area of the storage 140, and data generated while performing various operating programs is temporarily stored in the RAM area of the storage 140.

For example, the storage 140 may provide location information indicating that "AB" is assigned to one row and one column in the 4x3 key array of the input device 300, and that the "lower pair" function is assigned to three rows and three columns. Save it.

The display unit 150 displays the characters generated through the character generator 130 and displays a predetermined service screen and menu screen. Here, the display unit 150 is connected to the display device 200 of the mobile communication terminal 100 to display a text, a service screen and a menu screen.

The controller 160 controls the operations of the respective functional blocks 110 to 150 constituting the apparatus for text input.
