The invention discloses an over-area covering automatic detection method in a wireless honeycomb network. The over-area covering automatic detection method comprises the following steps of: when a user terminal wants to be switched to a target cell B from a source cell A, a base station in which the source cell A is located acquires the distance dAB between the source cell A and the target cell B, and judges the relation between the distance dAB and the distance threshold D; whether the main lobe range of the target cell B and the cover range of the base station in which the source cell A is located have overlapped areas is judged, and if not, the threshold N of the number of cell layer between the source cell A and the target cell B is set to be 0; and the cell layers n between the source cell A and the target cell B is calculated, whether n is larger than N is judged, and if so, the existence of the over-area covering problem in the target cell B is proved. The over-area covering automatic detection method is convenient to acquire parameters, and can be obtained without calculation, thus guaranteeing the computational efficiency. In addition, the threshold parameters D and N are self-adaptive, so that the over-area covering automatic detection method is applicable to urban areas, suburban areas and the adjacent positions of the urban areas and the suburban areas theoretically, thus fully embodying the advantages of SON technologies.
