Abstract: PURPOSE: A method and a device for management of a femto base station are provided to reduce inter-cell interference by minimizing the amount of information that is broadcasted by a femto cell base station even though the terminal to be managed does not exist. CONSTITUTION: A reception unit(112) receives an interval changing request from a second base station which includes a first cell and manages a second cell larger than the first cell. An interval charger(114) converts the interval of the first base station according to the interval conversion request. If the first base station is an unavailable interval, a broadcasting unit(111) does not perform broadcasting. If the first base station is a partial available interval, the broadcasting unit broadcasts only a preamble and simple broadcasting information. If the first base station is the available interval, the broadcasting unit broadcasts system information.
