Description
Claims (8)
- 무선통신시스템에서 핸드오프(Handoff)를 수행하기 위한 방법에 있어서,서빙 기지국으로부터 수신된 신호의 세기가 기준 값보다 작은 경우, 상기 서빙 기지국과의 순방향 전력 제어(Downlink Power Control)를 수행하는 과정과,상기 순방향 전력 제어가 수행된 시점부터 소정 시간 동안 상기 전력 제어가 적용된 수신신호 세기에 대한 평균을 산출하여 상기 기준 값과 비교하는 과정과,상기 수신신호 세기에 대한 평균이 상기 기준 값보다 작을 경우, 인접 기지국으로 핸드오프를 수행하는 과정을 포함하는 것을 특징으로 하는 방법.
