Abstract:
1. A system comprising: a first wireless communication base station; a second wireless communication base station; and a wireless communication device camped on the first wireless communication base station and in communication with the second wireless communication base station, wherein the first wireless communication base station is configured to: conduct a frequency scan by altering a clock frequency of its clock source across a frequency range; while performing the frequency scan, receive from the wireless communication device signal strength measurements of a signal between the wireless communication device and the second wireless communications base station as a function of a frequency being scanned; and select a desirable clock frequency for the clock source of the first wireless communication base station, wherein selecting the desirable clock frequency includes generating a Gaussian representation of the signal strength measurements as a function of scanned frequencies and selecting as the desirable clock frequency, a clock frequency in which the signal strength measurement is at a Gaussian center; receive frame number parameters associated with the second wireless communication base station at a rate that enables the determination of a clock drift rate; and derive an adjustment to the clock source of the first wireless communications base station and apply the adjustment to the clock source of the first wireless communications base station to converge the accuracy of the clock source of the first wireless communications base station to an accuracy of a clock source of the second wireless communications base station.
