Abstract

본 발명은 무선전화기의 DTMF를 이용한 데이타를 통신방법에 관한 것으로, 통화모드신 휴대장치(나)와 고정장치간(가)의 종래 구형파 데이타 통신으로 인하여 불필요한 신호가 국선으로 송출되어 잡음이 들리는 것을 막기 위해 휴대장치(나)에는 DTMF 신호를 출력하는 DTMF 수신부(160)를 구비하여 통화모드가 되면 DTMF 다이얼부(150')로 부터 송출되는 신호를 DTMF 수신부(160)가 다이얼 신호 및 기능에 해당하는 신호를 각각 분리하여 전자식 다이얼 이외에는 국선송출 신호를 뮤트시키는 동작을 수행하고, 통화종료 DTMF 신호가 들어오면 처음의 대기상태로 되어 상기 동작을 계속 수행하므로 무선전화기 사용자의 통화품질이 향상되는 발명이다.The present invention relates to a method of communicating data using DTMF of a wireless telephone, and that a signal is transmitted to a trunk line due to conventional square wave data communication between a portable device (b) and a fixed device in a call mode. In order to prevent this, the portable device (b) includes a DTMF receiver 160 for outputting a DTMF signal, and when the call mode is reached, the DTMF receiver 160 corresponds to a dial signal and a function transmitted from the DTMF dialer 150 '. It is an invention that the call quality of the wireless telephone user is improved by separating the signals to perform the operation of muting the trunk line transmission signal except for the electronic dial, and when the call termination DTMF signal is received, the first standby state is continued. .

Description

무선전화기의 DTMF를 이용한 데이타 통신방법Data communication method using DTMF of wireless telephone

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 고안 무선전화기 블럭도로서 (가)는 고정장치 블럭구성도이고, (나)는 휴대장치 블럭구성도이다.2 is a block diagram of a wireless telephone of the present invention, (a) is a block diagram of a fixed device, and (b) is a block diagram of a portable device.

제3도는 본 고안을 구현하기 위한 고정장치의 CPU 동작흐름도.3 is a flowchart of the CPU operation of the fixing device for implementing the present invention.

Claims (2)

휴대장치(나)에 DTMF 신호를 출력하는 DTMF 다이얼부(150')와, 상기 DRMF 신호를 수시하는 DTMF 수신부(160)를 고정장치(가)에 구비하여 휴대장치(나)의 CPU(110')는 통화모드시 채널을 탐색하고 이후 송신부를 동작시켜 통화시작 코드를 송출하고, 키보드(110')의 기능키 신호에 다라 해당기능별 DTMF 신호 송출을 송출완료시 까지 시행하고, 통화종료 DTMF키가 입력되면 통화종료 DTMF 신호를 송출하고 대기모드를 수행함을 특징으로 하는 무선전화기의 DTMF를 이용한 데이타 통신방법.The CPU 110 'of the portable device (b) includes a DTMF dial part 150' for outputting a DTMF signal to the portable device (b), and a DTMF receiver 160 for receiving the DRMF signal. ) Calls the channel in call mode and then operates the transmitter to send a call start code, and according to the function key signal of the keyboard 110 ', transmits the DTMF signal for each function until the call is completed. A data communication method using the DTMF of a wireless telephone, characterized in that when the input is terminated call DTMF signal and performs the standby mode. 제1항에 있어서, 고정장치(가)의 CPU(110)는 통화모드시 확인코드를 송출하고, 소정시간내에 DTMF 수신부(160)로 신호가 입력되면 기계식 및 전자식의 해당기능 DTMF신호를 분석하여 전자식 다이얼 이외에는 국선송출 신호를 뮤트시키는 동작을 해당가능 동작완료시까지 수행하고 통화종료 DTMF 신호가 입력되면 처음 대기상태로 되어 상기의 동작들을 반복 수행함을 특징으로 하는 무선전화기의 DTMF를 이용한 데이타 통신방법.According to claim 1, wherein the CPU 110 of the fixed device (A) transmits a confirmation code in the call mode, and if a signal is input to the DTMF receiving unit 160 within a predetermined time to analyze the corresponding function DTMF signals of mechanical and electronic A method of data communication using a DTMF of a radiotelephone, in which an operation for muting a trunk line transmission signal other than an electronic dial is performed until a corresponding operation is completed, and when the call termination DTMF signal is inputted, the operation is first waited. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
