METHOD AND APPARATUS FOR DETERMINING THE LOCATION OF A MOBILE STATION IN A CDMA COMMUNICATION NETWORK

摘要

An apparatus and method for locating a remote station in a synchronous communications network using the time of arrival of a reference pilot signal at the remote station as a time reference. The time difference of arrival (TDOA) of GPS signals received by the remote station and other signals received from a base station, are measured relative to this reference time. From these measurements, the location of the remote station is determined. The invention treats the location issue as a TDOA problem.
