SYSTEM AND METHOD FOR ESTIMATING POSITION OF MOBILE STATION IN WIRELESS NETWORK

摘要

PURPOSE: A system and a method for estimating a position of a mobile station in a wireless network is provided to accurately estimate the position of the mobile station in which an emergency call is generated and estimate the position of the mobile station without a high price multi-array antenna. CONSTITUTION: A timer(325) measures the first round trip delay related with a position estimation message transmitted from the first BTS(Base Transceiver Subsystem) to the first mobile station and a position estimation response message transmitted from the first mobile station to the first BTS. A power monitor(330) measures a power level of the position estimation response message received by the first BTS and determines that the received power level saturates a receiver related with the first BTS. A data processor(305) transmits a power control message from the first BTS to the first mobile station, increases the transmission power level of the position estimation response message in the first mobile station, saturates the receiver by the increased transmission power level, and calculates the first distance between the first mobile station and the first BTS from the first round trip delay.
