Claim:
1. A method for detecting a synchronization failure of a base station in a wireless communications network, the method comprising: receiving, at a server in the wireless communications network, synchronization data from one or more base stations in the wireless communication network, the synchronization data comprising a phase offset between two base stations; wherein the one or more base stations comprise a first base station, a second base station, and a third base station, and wherein the synchronization data comprises a first set of data, a second set of data, and a third set of data; wherein the server receives the first set of data from the first base station, the first set of data comprising phase offsets between the first base station and the second base station, and between the first base station and the third base station; computing a difference between each of the received synchronization data and corresponding control data; determining if the difference between one or more of the received synchronization data and the corresponding control data is outside of a predetermined threshold; and if the difference between one or more of the received synchronization data and the corresponding control data is outside of the predetermined threshold, identifying the base station of the one or more base stations that has the synchronization failure.
