Abstract

본 발명은 셀룰라폰에 관한 것으로, DTMF 신호에 대하여 모르스 부호로 문자를 정의하고 DTMF 신호를 이용한 송수신으로 장소에 구애됨이 없이 문자통신으로 통화의 신뢰성을 제공한다. 본 발명은 대기모드에서 통화모드로 전환되면 송신모드인가 수신모드인가를 판단하는 과정과, 송수신모드의 판단후 음성통신모드인가 문자통신모드인가를 판단하는 과정과, 음성통신모드이면 음성통화수단을 통한 음성 데이타의 송수신을 수행하고 문자통신 모드이면 키입력수단으로 부터 인가되는 키신호에 대해 DTMF 신호를 통한 문자데이타의 변복조로 표시수단을 통해 문자통화를 수행하는 과정을 포함한다. 또한 본 발명은 DTMF 신호에 정의된 모르스 부호를 저장하는 메모리 수단과, 수신되는 DTMF 신호를 문자로 복조하는 문자변환수단과, 수신되는 DTMF 신호를 검출수단 및 송신키신호를 DTMF 신호로 발생시키는 DTMF신호 발생수단을 구비한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular phone, and defines a character by Morse code for a DTMF signal, and provides reliability of a call through text communication without being tied to a place by transmission and reception using a DTMF signal. The present invention is a process of determining whether the transmission mode or the reception mode when the transition from the standby mode to the call mode, the process of determining whether the voice communication mode or text communication mode after the determination of the transmission and reception mode, the voice call means And transmitting and receiving voice data, and performing a text call through the display means by modulating and demodulating the text data through the DTMF signal with respect to the key signal applied from the key input means. In addition, the present invention provides memory means for storing the Morse code defined in the DTMF signal, character conversion means for demodulating the received DTMF signal into a character, DTMF for generating the received DTMF signal as a DTMF signal as a detection means and a transmission key signal. Signal generating means is provided.
