A cell handover method applied to a serving base station, comprising: sending measurement configuration information to a terminal located in a cell of the serving base station and to be handed over, wherein the measurement configuration information comprises beam configuration information; after the terminal measures neighboring cells according to the measurement configuration information, receiving beam measurement results sent by the terminal according to the beam configuration information; and determining, according to the beam measurement results, a target cell to which the terminal is to be handed over, and handing over the terminal to the target cell by means of a target network device; wherein the beam configuration information comprises a reported threshold and a reported number of the beam measurement results; before said determining a target cell to which the terminal is to be handed over according to the beam measurement results, the method further comprises: acquiring a moving speed of the terminal; said determining a target cell to which the terminal is to be handed over according to the beam measurement results comprises: when the moving speed is greater than or equal to a first preset speed threshold, determining, from the neighboring cells, the to-be-determined cells having serving quality greater than or equal to a first preset quality threshold, and determining the number of first beams of each to-be-determined cell, and determining the to-be-determined cell with the largest number of the first beams as the target cell, wherein the first beams are beams having the beam measurement result greater than or equal to the reported threshold; when the moving speed is less than the first preset speed threshold and greater than or equal to a second preset speed threshold, determining the cell with the highest serving quality as the target cell; or determining any cell in the to-be-determined cells as the target cell; and when the moving speed is less than the second preset speed threshold, determining the cell with the highest serving quality as the target cell. sending measurement configuration information to a terminal located in a cell of the serving base station and to be handed over, wherein the measurement configuration information comprises beam configuration information;
