According to a method of an embodiment of the present disclosure, a method for correcting a beamforming pattern of a base station by an analysis server of a base station management network may comprise the steps of: when network management information is received from a first base station, identifying whether or not the network management information indicates the occurrence of a failure in an antenna element of the first base station; when the network management information indicates the occurrence of the failure in the antenna element of the first base station, analyzing an effect of a beamforming pattern of the first base station and analyzing a change in a cell coverage; on the basis of the result of the analysis, determining a first beamforming pattern for compensating for the failure in the antenna element; and transmitting, to the first base station, information about the first beamforming pattern by including the information in management control information.
