Claims (10)
- 무선 인터페이스를 이용하는 통신 채널을 통해 음성 및 데이타 신호를 전송 및 수신하기 위한 모빌 전화기에 있어서, 무선 트랜시버 ; 통신 채널 상태를 검출하는 검출 수단 ; 데이타 입력 포트 ; 데이타 보호 코딩을 데이타에 부가하기 위한 선호 코딩 수단을 포함하는 제 3 처리기와 ; 상기 검출 회로에 접속된 제 2 제어 수단으로서, 양호한 또는 양호하지 못한 통신 채널 상태를 결정하고, 양호한 통신 채널 상태가 결정될 때, 상기 제 2 제어 수단을 통해, 상기 데이타 입력 포트에서 상기 무선 트랜시버로 데이타가 전달되도록 데이타 흐름을 제어하고, 양호하지 못한 통신 채널 상태가 결정될 때, 상기 제 3 처리기를 통해, 상기 데이타 입력 포트에서 무선 트랜시버로 데이타가 전달되도록 데이타 흐름을 제어하는 제 2 제어 수단을 포함하는 모빌 전화기.
- 제1항에 있어서, 상기 신호 코딩 수단은 보호 코딩을 상기 데이타에 부가하기 위한 에러 보정 프로토콜 처리기를 포함하는 모빌 전화기.
- 제2항에 있어서, 상기 보정 프로토콜 처리기는 포워드 에러 보정 엔코딩 기법을 이용하는 모빌 전화기.
- 제3항에 있어서, 상기 프로토콜 처리기는 리드-솔로몬 형태의 엔코더를 포함하는 모빌 전화기.
- 수용 가능 또는 수용 불가능한 통신 상태에 따른 전송환경에서 이동 무선 전화기로 동작하기 위한 무선 데이타 전송 시스템에 있어서, 트랜시버 ; 음성 및 데이타 처리 유닛 ; 수용 불가능한 통신 상태를 검출하기 위한 채널 상태 모니터링 수단 ; 및 데이타 모뎀을 포함하고, 상기 데이타 모뎀은, 데이타 입력 포트 ; 변조기/복조기를 구비하는 데이타 처리 회로 ; 및 전송을 위한 데이타 신호들의 프레임들을 구성하기 위한 데이타 모뎀 제어기로서, 상기 채널 신호 상태 모니터링 수단에 응답하여, 상기 데이타 입력 포트를 제 1 수단과 제 2 수단을 경유하여 상기 음성 및 데이타 처리 유닛에 제어 가능하게 결합하기 위한 데이타 경로를 선택하기 위한 데이타 모뎀 제어기를 포함하며, 상기 제 1 수단은 수용 가능한 통신 상태 동안 데이타 모뎀 제어기와 음성 및 데이타 처리기 사이의 집적 접속을 통해 데이타 모뎀 처리량을 음성 및 데이타 처리기에 결합하기 위한 수단이고, 상기 제 2 수단은 수용 불가능한 통신 상태 동안 정확성을 향상시키기 위해 신호를 엔코딩 하는 데이타 처리 회로에 데이타를 전송하는 접속을 통해 음성 및 데이타 처리기에 데이타 모뎀 처리량을 결합하고, 엔코드된 신호를 모뎀 제어기에 결합하고 그로부터 음성 및 데이타 처리기에 결합하는 수단인 무선 데이타 전송 시스템.
- 제5항에 있어서, 상기 데이타 처리 회로는 포워드 에러 보정 엔코딩 기법을 이용하는 무선 데이타 전송 시스템.
- 제5항에 있어서, 상기 음성 및 데이타 처리 유닛과 채널 상태 모니터링 수단을 구비하는 트랜시버 장치를 포함하는 무선 데이타 전송 시스템.
- 제5항에 있어서, 시스템 상태에 따라 결합하는 제 1 및 제 2 수단을 제어하기 위한 수단을 더 포함하는 무선 데이타 전송 시스템.
- 제8항에 있어서, 상기 제어하기 위한 수단은 오디오 통신 경로의 비-사용성에 응답하여 데이타 모뎀을 임시로 디스에이블링 하는 수단을 포함하는 무선 데이타 전송 시스템.
- 제1항에 있어서, 상기 무선 트랜시버는 검출 회로를 포함하는 모빌 전화기.
