| Nowadays,with the rapid changes of information transmission technology and mobile communication,LTE network technology has been widely used and widely recognized by countries around the world.Based on the LTE network of Siping Branch of CMCC as the project background,this paper makes a deep theoretical and practical research on reducing the proportion of cells with uneven load in LTE network.The structure and content of this paper research design,first,combined with the background of technology,analyzes the recent research status at home and abroad;Secondly,from the perspective of LTE system organization structure and main application technology,this paper introduces orthogonal frequency division multiplexing technology,smart antenna technology,antenna multiple input multiple output technology and self-organizing network technology of LTE network.Then,according to the analysis of various LTE cell load imbalance scenarios,the following conclusions are summarized:(1)the coverage is not ideal;(2)the setting of load balancing parameters is unreasonable;(3)the setting of handover strategy is unreasonable;(4)the RF adjustment is unreasonable;In the aspect of reducing the proportion of cells with uneven load in LTE network,this paper mainly adopts the method of network system optimization.By solving the coverage problem,reasonable neighbor cell optimization configuration,and antenna adjustment and other solutions,it ensures and improves the LTE network user perception,such as the optimization of download rate,call drop rate and so on.Then according to the theoretical analysis,put it into practice.Revised and verified in the work to achieve the ultimate goal of reducing the load imbalance of LTE network.The overall design of this paper has important reference significance to reduce the ratio of uneven cell load in LTE network,and then improve the LTE network index and user perception. |
