Application Of LTE Optimization Technology Based On Dense Scenes Of Three Layers And Two Types Stereo Network System

LTE?Long Term Evolution,long term evolution?is the long term evolution developed by 3GPP universal mobile communication system technology standard,is one of the fourth generation mobile communication technology,LTE system introduced OFDM?Orthogonal Frequency Division Multiplexing,orthogonal frequency division multiplexing?and MIMO?Multi-Input&Multi-Output,multiple input multiple output?key technology,significantly increase the spectrum efficiency and the wireless data transmission rate.LTE system supports 1.4MHz,3MHz,5MHz10MHz,15MHz,20MHz variety of bandwidth allocation,not only to support the global mainstream 2G/3G currently in use frequency,also supports some new bands,and thus more flexible spectrum allocation,system capacity and coverage can be significantly improved^[1].LTE system,relative to the 2 3G network,the whole network structure is more flat,divided into the wireless access network?E-UTRAN?and the core network EPC?MME/S-GW?,reduce the network node and the complexity of the system,which can reduce the delay of network,and reduce network deployment and maintenance costs.With the development of the times,the number of 4G users has gradually increased,and the LTE network has played an important role in the service load.LTE network construction gradually perfect,the network element quantity increases unceasingly,the network optimization problems become more prominent,intensive regional inevitable network overlay,frequency interference between network elements,greatly reduce the efficiency of the network,the network quality deterioration;network capacity constrained high load area network,seriously affect the user perception,the research on how to reasonably deploy network intensive area the equipment,effectively improve the quality of network has become one of the focal points in the process of optimizing the network to improve network capacity at the same time,this paper from the intensive regional business activities to solve the sudden increase in the amount of questions to the full analysis of network capacity,the use of LTE network technology,network equilibrium adjust relevant parameters,try to use the new network,station,micro base station the combination of Acer,the use of different micro base station network effectively avoid interference,control range,Targeted absorption intensive regional traffic to enhance network perception.The optimization scheme through large-scale activities more personnel protection,analysis of the optimization scheme is effective measures to try to use the new tools,developed a series of intensive scenarios improve network quality,network optimization in the later can be targeted promotion,to intensive regional network optimization,improve the network quality of a certain reference.
