Abstract

본 발명은 셀롤라 시스템내에서 이동장치(412)의 위치를 결정하기 위한 방법 및 장치에 관한 것이다. 공통위상을 가진 동기화된 신호는 시스템내의 각 기지국(400, 401, 402)에서 발생된다. 이동장치(412)는 신호음을 전송한다. 각 기지국(400, 401, 402)은 위상 오프셋을 발생시키기 위해 신호음의 위상을 동기화된 신호의 공통위상에 비교한다. 시스템 제어기는 제1기지국(400)의 위상 오프셋 및 제2기지국(401)의 위상 오프셋사이의 차를 비교하여, 제1기지국(400) 및 이동장치(412) 사이의 거리와 제3기지국(402) 및 위치의 쌍곡 또는 선형 라인을 한정하는 이동장치(412) 사이의 거리차를 결정한다. 시스템 제어기는 제1 및 제2쌍곡선의 교점을 결정하여, 이동장치(412)의 위치를 결정한다.
