Abstract: The present invention provides a radio resource optimization and management method, a centralized controller, and a base station. In the method, the centralized controller determines a work status series and a work policy series of each cell during a first time period; and sends the work status series and the work policy series of each cell to each cell, so that each cell adjusts resources of this cell according to the work status series and the work policy series, thereby enhancing a network KPI at a large time granularity by means of distributed cell coordination while ensuring local KPI performance of each cell. In contrast with distributed coordination optimization in a single coordination state, the present invention provides a higher degree of freedom in terms of a time dimension, and therefore provides better performance in terms of a network KPI at a large time granularity.
