Methods and apparatuses for synchronozing basestations in a cellular network . One exemplary method performs time synchronization between at least tow basestations, a first basestation and a second basestation, of a cellular communication system. In this exemplary method, a first time-of-day and a first geographical location of a first mobile cellular receiver station (MS) are determined from a first satellite positioning system (SPS) receiver whic h is co-located with the first MS, and the first time-of-day and first locatio n are transmitted by the first MS to a first basestation which determines a ti me- of-day of the first basestation from the first time-of-day and first locatio n and from a known location of the first basestation. Also in this exemplary method, a second time-of-day and a second geographical location of a second MS are determined from a second SPS receiver which is co-located with the secon d MS, and the second time-of-day and the second location are transmitted to a second basestation which determines a time-of-day of the second basestation from the second-time-of-day and the second location and a known location of the second basestation. Other methods and apparatuses are also described for synchronizing basestations in a cellular network.
