Abstract
A method for estimating the movement of a terminal of interest with respect to an access network. An incoming frequency of a message of interest transmitted by the terminal of interest and received by a pair of base stations of the access network are measured. The incoming frequencies of calibration messages transmitted by calibration terminals and received by the pair of base stations are measured. A differential measurement error according to the incoming frequencies of the calibration messages is estimated. A difference in incoming frequency of the message of interest according to the incoming frequencies of the message of interest and according to the differential measurement error is estimated. The movement of the terminal of interest according to the difference in incoming frequency of the message of interest is estimated.
