移动无线网络优化（Mobile radio network optimization） Network optimization: mobile radio network optimization The network optimization of mobile communication system mainly includes two aspects: the optimization of wireless network and the optimization of switching network. The wireless part of the system has many uncertainties, and it has a great impact on the wireless network, and its performance is often the decisive factor in the quality of mobile communication network service. The optimization of wireless network is a task with large amount and complicated process. Here are some of the experiences and experiences of optimizing wireless networks in actual work. First, the way to discover the quality of wireless networks: 1, DT (driving test): when the car is running at a certain speed, using the test instrument, test mobile phone, the signal intensity in the vehicle meets the requirements of normal conversation, whether there is congestion, interference, drop phenomenon test. 2, CQT (fixed point network quality test): in the service area to select multiple test points, a certain number of call calls, to reflect the quality of the network from the users point of view. Test points are generally selected in the communication of relatively concentrated occasions, such as hotels, airports, stations, important departments, office buildings, gatherings and so on. 3, OMC data analysis: OMC traffic statistics is an important way to understand the network performance indicators, it reflects the actual operation of wireless networks. Through the analysis of the statistical data of the service area can be found inscribed pass rate, fall rate of wireless cell abnormalities, also can the quality of the wireless network to conduct a comprehensive assessment, such as the handover success rate, paging success rate, congestion rate, Diaohua rate. 4, user declaration: to understand the quality of network through user complaints, has found problems in a timely manner, pertinence, we also und
