Research On Coverage Optimization Technology Of Mobile Communication Network

With the continuous development of Shanghai Telecom mobile communication network,the optimization engineers can optimize the wireless network coverage by using the network simulation method.In this paper,we start with the research of the system simulation process and principle,and complete the parameters configuration in the simulation system for the optimal coverage.Because of the construction,the population and the density of the simulation model has a great influence on the establishment of the simulation model,so the different characteristics of the region to take a different program optimization.In the construction area,the initial optimization scheme is simulated and implemented in the simulation software.The simulation results are presented,and the optimal scheme is obtained.Finally,the overall coverage of the experimental area is improved by 3dB.In the construction area,the use of ACP automatic optimization tools,automatic generation of optimization scheme,the actual implementation of the experimental area to achieve the results in the condition that does not reduce the coverage,improve the signal to noise ratio of 5.6% results.To the extent of population density,the typical traffic transfer situation,the network coverage under different traffic conditions,and the more effective optimization scheme are completed by simulating the typical traffic transfer.PN code for the base station sector of the CDMA system to distinguish between code,because of its existence,the same and adjacent PN interference are the main factors that affect the micro cell and macro cell base station coverage.Therefore according to the density of base stations in Shanghai city and suburban areas,the use of simulation tools to assist in planning,the city's network of targeted PN planning.After the planning,it can effectively reduce the PN conflict,and enhance the overall coverage of the network.Because of the LTE optimization ideas and 2G/3G network similar to the actual application of the simulation module for the LTE planning to optimize the analysis,get the LTE base station within the range of 30 to 50 meters for the best results,for the simulation module in the LTE network in a better application.
