摘要： A mobile communication terminal having QWERTY keys and a method for outputting Dual Tone Multi-Frequency (DTMF) signals thereof are disclosed. The user inputs information including alphabetic characters that is requested by a directory system, while viewing the alphabetic characters marked on the QWERTY keys. The mobile communication terminal outputs DTMF signals of symbols marked on the input QWERTY keys identical to the DTMF signals of the corresponding symbols of keys arrayed in a conventional 3×4 key array format. The alphabetic keys of the QWERTY keys output DTMF signals identical to those of the keys of the 3×4 array format in an alphabet input mode. Therefore, the user can easily input information requested by the directory system while viewing the symbols marked on the QWERTY keys, without requiring the user to memorize the array of alphabetic characters of the 3×4 key array format.
