The data mapping module is configured to establish a mapping relationship between the collection task and the data required by the collection task, and select data required by the user from the data collected according to the collection task according to the mapping relationship. Taking the user management side storage module as a database, since the data stored in the database is large, the data required by the user-customized collection task is only a part of the data stored in the database, so the mapping between the collection task and the required database can be performed according to the collection task.

Further, in this step, the base station side may further classify and store the collected data, where the classified storage may be classified and stored according to the type of the base station, the type of the base station subsystem, and/or the type of the base station subsystem module, for subsequent data. Analyze use. Further, in this step, the state of the transmission link for transmitting the collected data between the base station side and the number of user management sides may be monitored in real time, and when the transmission link is abnormal, the collection operation on the base station side is stopped. Thereby avoiding invalid collection tasks running all the time and consuming system resources. Preferably, the monitoring of the link status can be implemented by heartbeat detection. Further, in this step, the collection operation may be controlled according to a preset scheduling policy. Specifically, the maximum amount of data collected each time may be preset to prevent the impact of excessive data on the communication system; The collected data can also be set to collect data in different time periods.
