Wireless communication network optimization is a hotspot and a difficult point in the field of wireless communication. Wireless communication network optimization is based on a large number of accurate network coverage data. The usual wireless communication network coverage data is obtained by the engineering personnel's field signal measurement, and is generally used in the initial stage of the wireless network. After the wireless communication network is commercialized, the network is continuously optimized through network management statistical data analysis, user complaints, and manual road test. The statistics of network management are the main reference data for wireless communication network optimization. In recent years, the use of terminals (User Equipment, UE) to measure and report the quality of wireless network signals, to sort and analyze the measurement data, and to provide reference data for wireless communication network optimization has been paid more and more attention.

As shown in Figure 4, the process of triggering measurement and data reporting by the base station is as follows:

Step 31: The base station receives the measurement configuration parameter of the network management, determines whether the switch is turned on (START) or stops (STOP), if the switch is STOP, then proceeds to step 32; if the switch is START, then proceeds to step 33;

Step 32: Stop sending the REP-REQ message and the SCN-REQ message to the UE, and wait for the REP-RSP message and the SCN-RSP message reported by the UE, and then perform step 34;
