An xDR bill is a detailed session-level record of the signaling process and business transfer process generated after full-volume Internet data is processed. The bill contains all the Internet access information of the user, which is worth analyzing and mining. The xDRILL bill acquisition system is an xDR bill acquisition system developed by Haohan Data. It can, based on the data collected by DPI, efficiently and flexibly generate xDR bills under various application scenarios so as to provide a basis for resource analysis and data mining and facilitate in-depth analysis and mining of various application platforms.
