Design And Implementation Of LTE Wireless Networks Optimization Scheme

With the development of LTE networks,the importance of wireless network optimization is increasing.With high bandwidth and low latency,LTE networks have been widely used.Although the fifth-generation communication technology has taken shape,4G is still the mainstream communication technology,adjusting and optimizing the LTE network system structure and improving system operation efficiency.Not only can improve the service quality of 4G communication system,but also have a positive impact on the future 5G network optimization.This paper combines engineering practice,user-oriented,and enhances user perceived quality.Based on the specific network operation problem,this paper attempts to solve the engineering reality from the perspective of engineering optimization and comprehensive consideration of network performance and cost problem.This paper systematically studies the LTE network architecture,interface protocol and related key technologies OFDM,MIMO,which lays a theoretical foundation for the development of the thesis.By summarizing the network engineering optimization problems,this paper divides it into coverage dimension,capacity dimension and quality dimension,which is helpful to quickly locate the source of the problem in actual network optimization.On this basis,the network problems covered by different dimensions and their corresponding parameter indicators are comprehensively evaluated,and the judgment basis of network problem dimension attribution based on quantitative parameter indicators is attempted,and this is used as the main reference factor for the design of subsequent network optimization schemes.According to the basic process of network optimization,this paper gives specific cases and optimization scheme design based on the aforementioned model for network problems such as weak coverage,overlapping coverage,interference problems,poor CQI quality,capacity expansion and communication guarantee.The designed optimization scheme was implemented in engineering,and the optimized results achieved were in line with expectations.It is verified that the network problem location model proposed in this paper and the design idea of the optimization scheme are feasible in engineering.
