Abstract
A telecommunications system and method is disclosed for improving the accuracy of the Time of Arrival (TOA) information extracted from the Timing Advance (TA) values reported by base stations. This can be accomplished by utilizing an average of m (m=2 or more) consecutive TA values, which will on average have a smaller mean-squared error than using a single TA value. By averaging multiple consecutive TA values to obtain a single measurement of TOA, the accuracy of the location algorithm employing the TOA information can be improved, and thus, the geographical location of a mobile terminal within a cellular network can be more accurately determined. The improvement in the accuracy of the location of the mobile terminal can be applied to both a stationary mobile terminal and a moving mobile terminal.
