Claims (3)

  1. 복수 이동장치에 각각 공통의 복수 무선 채널을 갖추게 하고 통화시에 이들 무선 채널 중에서 빈채널을 선택하여 대향하는 모장치와의 사이에 무선 통화로를 형성하는 멀티 채널 억세스 방식을 적용한 이동 통신 시스템의 무선 채널 서어치 방식에 있어서, 각 이동 장치 및 모장치는 각 이동장치마다 복수 무선 채널중에서 선택 설정된 무선 채널수보다도 소수의 우선 사용 채널의 번호 정보를 기억한 우 선사용 채널 기억 장치(A)와, 수신대기시에 이 우선사용 채널기억 장치(A)에 기억되어 있는 우선 사용 채널의 번호 정보에 따라서 이들 각 우선사용 채널에 대하여 순차적으로 수신 서어치를 행하고 동시에 이수신 서어치를 행하고 있지 않는 기간에 수신 회로부로의 급전을 정지하는 수신 대기 제어장치(B)와, 수신 대기시에 대향하는 상대 장치에 대한 통화로 형성 요구가 발생했을 때, 상기 수신 서어치에 의하여 빈채널을 검출하고 이 빈채널을 사용하여 대향하는 상대방 장치와의 사이에서 소정의 접속제어를 행하고, 또한, 수신 서어치 중에 대향하고, 상대방 장치에서 접속 요구가 수신되었을 때에 수신 서어치 동작을 정지하고 이 접속 요구를 수신한 무신 채널에 의하여 대향하는 장치와의 사이에서 소정의 접속제어를 행하는 접속 제어장치(C)를 갖추고 있는 것을 특징으로 하는 무선 채널 서어치 방식.
  2. 제1항에 있어서, 우선 사용 채널 기억장치(A)는 전원 투입시마나 우선 사용 채널을 선택 설정하여 기억하는 것을 특징으로 하는 무선 채널 서어치 방식.
  3. 제1항에 있어서, 우선 사용 채널 기억장치(A)는 이동장치의 충전시 또는 통화시에 난수를 사용하여 새로운 우선 사용 채널을 선택 설정 및 기억하고 동시에, 이 새로운 우선 사용 채널을 대향하는 장치에 전송하여 기억시키는 것을 특징으로 하는 무선 채널 서어치 방식.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
