发明名称 POSITION LOCATION WITH A LOW TOLERANCE OSCILLATOR
摘要 The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodime nt of the invention comprises a method of performing position location in a wireless subscriber unit having a local oscillator, including the steps of receiving a position location request, acquiring a timing signal when a sufficient period of time has elapsed since the local oscillator has been corrected and correcting said local oscillator using a correction signal bas ed on said timing signal, substantially freezing the correction signal, performing a position location procedure using the local oscillator with the correction signal applied, and ending said position location procedure.</SDO AB>
