Wireless network optimization is to find out the reasons that affect the network quality by means of traffic data analysis, field test data collection, parameter analysis and hardware inspection. And through modifying parameters, adjusting network structure, adjusting equipment configuration and adopting some technical means (using MRP planning method, etc.) to ensure the high-quality operation of the system. ), so that the existing network resources can get the best benefit and maximum benefit with the most economical investment.

The workflow of network optimization includes five aspects: system performance collection, data analysis and processing, making network optimization scheme, system adjustment and redefining network optimization objectives.

When optimizing the network, we should first collect system information through OMC-R, and also collect information improvement issues such as user declaration, daily CQT test, DT test, etc., to understand users' opinions on the network and the defects existing in the current network, test the network, and collect network operation data. Then analyze and process the collected data to find out the root of the problem; According to the results of data analysis and processing, the network optimization scheme is formulated and the network is adjusted systematically. After the adjustment, the information of the system is collected, the new optimization goal is determined, and the problem is solved repeatedly, so that the network is further improved.
