The 230MHz wireless private network system has been applied in the power industry in a certain scale, and in the application process, the network needs to be monitored, the whole network needs to be evaluated, the coverage needs to be optimized, and the like. At present, a plurality of schemes exist for network evaluation and coverage optimization, such as work parameter checking, MR (Measurement Report) statistics, drive test analysis, CQT test (call quality dialing test) and the like, although the CQT test can accurately locate problem points, the CQT test is time-consuming and labor-consuming, has low efficiency and is limited by roads, and is difficult to test in a plurality of areas with coverage problems; the MR statistical efficiency is high, the related indexes to be tested can be rapidly obtained, but the positioning is not accurate enough and can only be positioned to a cell.
The signal quality of the terminal in wireless communication changes according to factors such as weather, environment, position and the like, and if the reporting period of the measurement result reported by the terminal is too long, the result monitored by the network side cannot truly reflect the change condition of the measurement result of the terminal; if the reporting period of the measurement result reported by the terminal is too short, the transmission resource of the air interface is excessively occupied, the single frequency point resource amount on the 230MHz frequency band is small, and the transmission of normal service data is influenced by the measurement and reporting of the narrow-band terminal which is performed too frequently.

And the combination of various factors such as the main zone level, the main adjacent level difference, the adjacent zone quantity and the like is supported, and the indoor and outdoor judgment results are judged and output through a combined model. However, if the RSRP (Reference Signal Receiving Power) is the same, the demodulation capability of the system will be reduced and the service transmission capability will be weakened if the system is subjected to strong Signal interference. And the demodulation performance of different systems is different, and network transmission and coverage analysis by only counting RSRP may not truly reflect the coverage condition, demodulation capability and service transmission performance of each system.
