The present invention relates to a method for performing an interference management based on received interference signal strength, the interference management apparatus comprises a parameter setting unit configured to set up a permissible interference reference IA of an allowable band and a percentage reference Q of an interference region, a communicating unit configured to receive information related to the received interference signal strength which is measured by at least a terminal from at least a terminal or a base station, and a comparing and determining unit configured to determine that interference excess is generated, in case that the received interference signal strength iA of an allowable band exceeds the permissible interference reference IA. According to the present invention, it is available to figure out an interference effect which a victim receiver undergoes within a permitted region accurately.
