A method includes acquiring a global handover performance parameter R, a local handover performance parameter r, and a handover parameter of a cell within a preset time; and detecting a handover problem, existing within the preset time, of the cell according to R and r. The method further includes receiving Rj, rj, a handover parameter, and indication information for a handover problem, within the preset time, of each adjacent cell that are sent by all adjacent cells; and determining whether the cell is a cell to be optimized. If an ith cell is a cell to be optimized, the method optimizes, according to Ri, ri, Rj, and rj, a handover parameter of the ith cell, and the handover parameters of the adjacent cells of the ith cell by using a data statistical regression method, a handover parameter corresponding to a handover problem of the ith cell.
