针对传统覆盖空洞检测方法投入大量人力物力，效率低的问题。利用运营商信令系统海量的用户行为数据进行3G网络覆盖空洞建模，提出一种基于用户行为的EDBSCAN-最小圆覆盖模型进行覆盖空洞检测。测试结果表明，该模型既能检测到覆盖空洞，又能准确确定覆盖空洞位置。

Conventional methods of coverage holes detection are very much resource consuming. A new detection method is proposed which make use of the massive amount of user behavior information from mobile signal system. A user behavior based EDBSCAN-smallest enclosing circle method to model the coverage hole is described and simu-lated.The result shows this model outperforms conventional models let alone being fast, precise and free of manual inter-vention.
