Abstract
A method and apparatus for correcting for Doppler shift in GSM signals at a mobile handset in communication with a base station is provided. The rate of change of position of the mobile unit is detected in relation to the base station and a Doppler correction is derived from the rate of change. This can be used when calculating the synchronization of the UMTS timebase from the GSM network information.
