1. A method performed by an analysis server in a base station management network, the method comprising:
receiving network management information including identifier information of an entity management system (EMS), wherein the EMS is associated with a base station and the analysis server; and
in case that the network management information indicates an antenna element failure occurrence of a base station:
analyzing a beamforming pattern impact and cell coverage change of the base station;
determining a first beamforming pattern correction parameter for compensating for the antenna element failure occurrence based on a result of the analyzing the beam forming pattern impact and the cell coverage change; and
transmitting, to the base station, management control information including information on the first beamforming pattern correction parameter,
wherein the first beamforming pattern correction parameter is for remaining antenna elements, except for at least one antenna element in which a failure has occurred in the base station.
