Method and apparatus for measuring frequency of a basestation in cellular networks using mobile gps receivers

The cellular communication system medium frequency synchronizing base station method and device. To the invention, and a handle, claims a predicting to the base station transmission the cellular communication system and method for timing, comprising: The receiving base station launch's multiple time between the first cellular signal from the earliest the time of an symbolized; And a base station and second cellular signal the second time rate of the timing signal; And the first and second time the computer and base station associated frequency. At least satellite positioning system signal determination of mobile station of the locating time use and corresponding timing signal and a.
