Study On Network Interference Optimization Of TD-LTE Communication System

The TD-LTE communication system is also called Long-Term Evolution Time-Division Duplex(LTE-TDD),which is an important communication standard for 4G communication technology.The TD-LTE system is extremely vulnerable to interference due to its time-division characteristics,and the interference range is large,resulting in network quality degradation.Interference will cause the quality of the wireless channel to deteriorate,causing problems such as service access failure,handover failure,disconnection,and low service speed,which seriously affect user perception.So in TD-LTE network optimization,interference has become one of the key factors that must be considered.This article analyzes the internal,inter-system,and external interferences that affect user perception on a class-by-class basis,digs deep into the theoretical basis of various interferences,analyzes their causes,and explores precise positioning methods.The research combines network management performance data and drive test data,and combines three-dimensionally from the time domain,space domain,and frequency domain to greatly improve the accuracy of background positioning interference types.Then,for the nine major types of interference,the optimization methods are studied one by one,and accurate optimization schemes are given,and the advantages and disadvantages of several different schemes are compared.Overlay coverage interference is becoming increasingly prominent in the current situation where the distance between sites and stations is continuously reduced,and multi-layer networking and multiple frequency bands share the same celestial surface,and the proportion of highly integrated antennas currently used to save astronomical resources has increased dramatically,bringing traditional antenna adjustment This is a big obstacle.This paper proposes to control the proportion of overlapping coverage interference cells by adjusting uplink power control parameters.Through adjusting and comparing the nine influencing uplink power control parameters one by one,the adjustment parameter group and recommended values are determined to solve the problem of overlapping coverage interference cells.The ratio is over 25%,with obvious results.With the continuous development of a legal society,the information collection methods and information collection equipment of law enforcement agencies have increased significantly.Among them,the increase of simulated base station interference has a great impact on the quality of wireless communication networks,causing serious interference.Aiming at the interference of the simulated base station,this paper has achieved phased results through the mobile terminal's mobility management in the connected state and the idle state,balancing the contradiction between information collection and network quality.The interference mapping and optimization ideas and methods in this paper are highly feasible.In the last chapter,case analysis for several typical interferences is given.According to the different types of interference characteristics and optimization schemes studied in this article,the interference optimization effect applied to Dalian's existing network is significant,which can greatly improve the accuracy of background positioning interference types,and output optimization directions and optimization ideas,which greatly improves the front-end interference processing staff.The efficiency of investigation and resolution has ensured the quality of the TD-LTE wireless communication network.
