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.

Abstract translation: 本发明提供一种无线电资源优化和管理方法，集中控制器和基站。 在该方法中，集中控制器在第一时间段内确定每个小区的工作状态序列和工作策略序列; 将每个单元的工作状态序列和工作策略序列发送给每个单元，使每个单元根据工作状态序列和工作策略系列调整该单元的资源，从而以较大的时间粒度提高网络KPI 分布式小区协调的手段，同时确保每个小区的本地KPI性能。 与单一协调状态下的分布式协调优化相反，本发明在时间维度方面提供了更高的自由度，因此在大的时间粒度下提供了更好的网络KPI性能。
