Claims (5)
- 이동통신단말기가 일 기지국으로부터 소형기지국으로 이동하는지를 판단하는 단계와;상기 이동통신단말기를 검출하는 활성기지국의 CCOX가 SVPX로 파일럿세기를 보고하도록 요청하는 단계와,상기 SVPX가 PMRM요청을 받으면 소정의 주기로 상기 CCOX로 PMRM을 전달하는 단계와,상기 PMRM을 수신하여 파일럿세기를 검출하는 단계와,상기 검출된 파일럿세기를 통해 상기 이동통신단말기가 기지국의 외곽에 위치하는지 여부를 판단하는 단계와,상기 이동통신단말기가 기지국의 외곽에 위치할 경우, 인트라 주파수간 핸드오프를 수행하는 단계를 포함하는 것을 특징으로 하는 인트라 주파수간 하드핸드오프 시점 결정방법.
- 제 1항에 있어서,상기 이동통신단말기가 기지국의 외곽에 위치해 있는지 여부를 판단하는 방법은 연속적으로 소정 회수(N1) 동안 수신된 PMRM에 따른 파일럿세기의 평균값이 최대 기준치보다 작거나 연속적으로 소정 횟수(N2) 이상 최저 기준치 이하로 내려오면 CCOX가 라운드트립딜레이값을 검출하여 파악하는 것을 특징으로 하는 인트라주파수간 하드핸드오프시점 결정방법
- 제 1항에 있어서,상기 SVPX에 의해 CCOX로 PMRM을 보고하는 도중에 그에 따른 파일럿 세기가 최대임계치보다 커지면 상기 CCOX는 SVPX로 PMRM 보고 중지를 요청하는 것을 특징으로 하는 인트라주파수간 하드핸드오프시점 결정방법.
- 제 1항에 있어서,상기 SVPX에 의해 CCOX로 PMRM을 보고하는 도중에 그에 따른 파일럿 세기가 최대임계치보다 작아지면 PMRM 보고를 다시 요청하는 것을 특징으로 하는 인트라주파수간 하드핸드오프시점 결정방법.
- 제 1항에 있어서,상기 SVPX에 의해 CCOX로 PMRM을 보고하는 도중에 상기 단말기가 다른 기지국방향으로 이동하는 것으로 판단되면 SVPX는 PMRM 보고를 중지하여 주파수간 핸드오프를 수행하지 않도록 한 것을 특징으로 하는 인트라주파수간 하드핸드오프시점 결정방법.
