基于CDL话单的高铁无线网络分析

Analysis on High-Speed Rail Wireless Network Based on CDL Bill

通过提取高铁站点的所有CDL话单,根据高铁列车上通话的特点,探讨高铁话单的筛选规则,用以筛选出在高铁上通话的话单,借由话单分析得到更为广泛和精确的高铁用户行为及网络数据,以此进行高铁无线网络的优化。

According to the characteristics of the high-speed rail calls, all CDL （Call Detail Log） bills in high-speed rail station are extracted. The filtering rules of high-speed rail are discussed to filter the bills of high-speed rail. By analyzing bills, the comprehensive and precise high-speed rail users’ behaviors and network data can be derived to optimize high-speed rail wireless network.
