- 코드분할다중접속 방식의 이동통신 시스템의 초기 액세스 모드 전송전력 제어에 있어서,단말기로부터 출력되는 초기 액세스 채널의 전송전력을 측정하는 단계와,상기 측정된 액세스 채널의 전송전력 레벨과 기 설정된 소정의 적정전력 레벨을 비교하는 단계와,상기 단계에 의한 비교결과 값에 차이가 있으면, 상기 차이값 n 비트의 전송전력 제어 메시지로 변환하고 해당 기지국을 통하여 상기 단말기로 전송하는 단계와,상기 기지국으로부터 전송된 전송전력 제어 메시지를 수신한 단말기에 의하여 트래픽 채널의 전송전력을 적정전력 레벨로 한번에 조정하는 단계로 이루어지는 구성을 특징으로 하는 이동통신 시스템의 전송전력 제어방법.
- 제 1 항에 있어서,상기 전송전력 제어 메시지는 상기 측정된 전송전력 레벨과 상기 적정전력 레벨과의 편차를 n 비트의 디지털 제어신호로 변환한 데이터 신호인 것을 특징으로 하는 이동통신 시스템의 전송전력 제어방법.
- 제 1 항에 있어서,상기 전송전력 제어 메시지는 페이징 채널을 통하여 기지국으로부터 단말기로 전송하는 것을 특징으로 하는 이동통신 시스템의 전송전력 제어방법.
