Abstract

본 발명은 무선전화기의 혼신시 자동채널변경방법 및 그 장치에 관한 것으로, 전화통화하는 중에 주기적으로 캐리어신호가 존재하는지를 무선전화기의 휴대장치에서 검사해서 캐리어신호가 존재하면 다른 무선전화기와 혼신된 것으로 인식해서 채널변경데이타를 무선전화기의 고정장치에게로 송출해 주게 되며, 고정장치가 휴대장치의 상기 채널변경데이타를 수신하게 되면 현재의 통화채널을 혼신없는 다른 통화채널로 자동적으로 변경해주도록 함으로써, 전화통화가 매우 편리해지도록 한 것이다.The present invention relates to an automatic channel change method and apparatus therefor when communicating with a wireless telephone. The portable device of the wireless telephone can periodically check whether a carrier signal is present during a telephone call, and if the carrier signal is present, it is interfering with another wireless telephone. It recognizes and transmits the channel change data to the fixed device of the wireless telephone. When the fixed device receives the channel change data of the mobile device, it automatically changes the current call channel to another communication channel without interference. It makes the call very convenient.

Description

무선전화기의 혼신시 자동채널변경방법 및 그 장치Automatic channel change method and device therefor in case of radio telephone

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

제2도는 본 발명에 따른 무선전화기의 구성도로, (가)는 휴대장치의 구성도, (나)는 고정장치 구성도.2 is a configuration diagram of a radiotelephone according to the present invention, (a) a configuration diagram of a portable device, and (b) a configuration diagram of a fixed device.

Claims (3)

전화통화중에 무선전화기의 고정장치에서 주기적으로 톤신호의 송출을 짧은 시간동안에 걸쳐서 중지시키는 제1과정과, 상기 제1과정에서 톤신호의 송출을 중지시키게 되면 무선전화기의 휴대장치에서 캐리어신호의 존재여부를 판단하는 제2과정과, 상기 제2과정에서 캐리어신호가 존재하는 것으로 판단되면 다른 무선전화기와 혼신된 것으로 간주해서 통화채널을 자동적으로 변경하는 제3과정을 포함하여 이루어진 것을 특징으로 하는 무선전화기의 혼신시 자동채널변경방법.The first step of stopping the transmission of the tone signal periodically for a short time in the fixed device of the wireless telephone during the telephone call, and the presence of the carrier signal in the portable device of the wireless telephone when stopping the transmission of the tone signal in the first step And a second process of determining whether or not a carrier signal exists in the second process, and a third process of automatically changing a communication channel, considering that the carrier signal is present. Automatic channel change method when the telephone is disturbed. 무선전화기의 고정장치에서 설치되어 전화통화시 톤신호를 발생하기 위한 톤발생부와, 상기 톤발생부에서 발생되는 톤신호를 송출하기 위한 상기 고정장치의 송신부와, 전화통화시 주기적으로 짧은 시간동안에 걸쳐서 상기 송신부의 전원공급을 차단해서 톤신호의 송출을 저지하는 고정장치의 마이크로프로세서(304)와, 무선 전화기의 휴대장치에 설치되어 상기 고정장치의 송신부가 송출해 주는 톤신호를 검출하는 톤검출부와, 상기 톤검출부에 의해서 톤신호가 검출되지 않으면 캐리어신호의 존재여부를 판단하여 캐리어신호가 존재하면 채널 변경데이타를 상기 고정장치에 송출해 주어 통화채널의 변경이 이루어지도록 하는 휴대장치의 마이크로프로세서(204)를 구비한 것을 특징으로 하는 무선전화기의 혼신시 자동채널변경장치.Installed in the fixing device of the wireless telephone, the tone generating unit for generating a tone signal during a telephone call, the transmitting unit of the fixing device for transmitting the tone signal generated in the tone generating unit, and periodically for a short time during a telephone call A microprocessor 304 of a fixed device which cuts off the power supply of the transmitter and stops the transmission of the tone signal, and a tone detector which is installed in a portable device of the wireless telephone and detects the tone signal transmitted by the transmitter of the fixed device. And, if the tone signal is not detected by the tone detector, determine whether a carrier signal is present, and if a carrier signal is present, transmit a channel change data to the fixed device to change the communication channel. And (204), an automatic channel change device for communication of the radio telephone. 제2항에 있어서, 전화통화를 위한 음성신호만의 출력을 위해 상기 톤신호를 억제하는 대역제한필터를 상기 휴대장치에 더 구비한 것을 특징으로 하는 무선전화기의 혼신시 자동채널변경장치.3. The apparatus of claim 2, further comprising a band limiting filter on the portable device for suppressing the tone signal for outputting only a voice signal for a telephone call. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
