Abrégé
(EN)
The invention is applicable to the field of communication, and provides an LTE micro base station, and a frame header deviation detection method and a synchronization method thereof. The frame headerdeviation detection method of the LTE micro base station comprises the steps of acquiring a first timestamp input to an external synchronous clock source of the LTE micro base station, and a second timestamp of a frame header of a local cell in last time; computing a difference between the second timestamp and the first timestamp to acquire a first time difference; and determining frame header deviation of a remote cell according to the first time difference. According to the base station and the methods provided by the invention, the frame header deviation of the remote cell can be automatically detected, the LTE micro base station can be quickly and accurately synchronized, deployment speed and efficiency of the LTE micro base station are improved, participation of manual configuration is reduced, system configuration accuracy is improved, and work efficiency is effectively improved.
