Abstract: In order to take full advantage of the wireless network resources and improve the quality of municipal wireless networks, this paper makes full use of DBSCAN(Density Based Spatial Clustering of Applications with Noise) algorithm and proposes a traffic abnormal cells detection method. Some statistical analysis of the existing network traffic data has been done to identify the relationship between carrier configuration and the best traffic. This article optimizes the cell’s carrier configuration, which has unusual traffics and high congestion rates. It also has guiding meaning for city cell wireless network optimization.

Key words: data mining, clustering, partition, Density Based Spatial Clustering of Applications with Noise(DBSCAN), carrier optimization, best traffic

摘要: 为了充分利用无线网络资源,提升无线网络质量,充分利用了DBSCAN(Density Based Spatial Clustering of Applications with Noise)算法的优点,提出基于划分DBSCAN算法的话务量异常小区的检测方法,并通过对现网大量话务数据的统计分析,找出小区载频配置数和最佳话务量之间的关系。对话务量异常、拥塞率高的小区进行载频配置优化,并对城市小区网络优化有一定的指导意义。
