Claims (3)
- 기지국으로부터 수신된 데이터에 에러가 발생되면, 타겟 SIR 값을 (DELTA A)*(Ratio)만큼 상승시키고, (DELTA A)*(1-Ratio)를 누적관리하는 제1과정과;상기 에러가 발생되지 않고, 타겟 SIR의 누적값이 있으면, 타겟 SIR 값을 (DELTA A)*(Ratio)만큼 상승시키고, 상기 누적값을 (DELTA A)*(1-Ratio) 만큼 차감하는 제2과정을 포함하여 이루어지는 것을 특징으로 하는 이동통신 단말기의 서비스 품질 향상방법.
- 제1항에 있어서, 상기 에러는CRC 에러인 것을 특징으로 하는 이동통신 단말기의 서비스 품질 향상방법.
- 제1항에 있어서,상기 에러가 발생되지 않고, 타겟 SIR의 누적값이 없으면,상기 타겟 SIR 값을 소정 DownStep 만큼 차감하는 제 3 과정을 더 포함하는 것을 특징으로 하는 이동통신 단말기의 서비스 품질 향상방법.
