Research On The Method Of LTE Network Engineering Optimization

With the advent of the information age,the level of information not only represents the level of people's living standards,but also has become an important yardstick to judge the development level of a country.On the one hand,new technologies represented by 5G are pushing out the old.On the other hand,4G technology is gradually replacing the traditional 2G and 3G technologies,becoming an important support for China's future data and voice services.Engineering optimization is a LTE 4G after the completion of a new station,professional technicians from operation and maintenance department of the operator shall conduct on-site test to judge and evaluate a series of problems such as data index,the construction of qualified level,covering the continuity and a series of problems to determine assessment.According to the test and evaluation results,aiming at the existing problem of site processing solution of an optimization work,optimization work shall be carried out to solve the problem.As a base station in front of the net for the first time optimization,engineering optimization work,qualified indicators,to approve the base station.Today telecommunication operators begin to build 5G base stations,but also begin to focus on the overall network coverage effect,and begin to replace traditional2 G,3G devices with 4G LTE systems.This time,replace 2G,3G voice services with4 G,it is necessary to ensure the continuous coverage of 4G base stations.Therefore,the construction of 4G base stations will not stop,but will speed up the construction and pay more attention to quality.So how can we get the new base station into use faster and better and reduce the daily optimization cost of the later base station when large-scale construction of 4G base station?LTE project optimization,as the first special optimization work of base station network entry,can ensure the healthy network entry of base station and reduce the investment of manpower and material resources in the later stage of daily optimization.Its advantages and importance are gradually highlighted.In this context,this paper studies the engineering optimization methods of thekey links in 4G base station construction.In this paper,key technologies and key parameters of LTE are studied and discussed.The article introduces the LTE project optimization steps and the base station cluster partition,point out the engineering optimization optimization work,which network problems for these problems,causes,discuss how to deal with,and is the most commonly used engineering optimization process,is also the most critical three problem optimization method were discussed,analysis of the principle.Finally,according to the actual work situation,take the city where the author works as an example to verify the effect and situation of engineering optimization method in dealing with the actual problem site,and find the solution to the existing problem in engineering optimization by integrating a large number of literatures and methods in practical optimization work.This research is based on the engineering optimization of daily work,closely fit with the actual.The content of the contribution is:(1)This paper summarizes the whole contents and steps of engineering optimization,analyzes the optimization of a newly built td-lte site,three key steps of important single site test optimization,cluster division and optimization,and whole network optimization.The classification criteria of cluster optimization are analyzed and expounded.(2)According to the needs of engineering optimization and daily work,this paper summarizes three network problems that need to be solved in the optimization work:site interference problems,site coverage problems and site switching problems.In addition,it analyzes several forms,causes and solutions of interference problems,covering problems,switching problems and solutions.(3)All the optimization methods are summarized and analyzed.Eliminate non network optimization methods such as engineering rectification and closing interference sources.This paper summarizes three main optimization methods of three network optimization departments to deal with engineering optimization: PCI optimization,antenna adjustment,switching parameter adjustment.The principles of the three methods are analyzed and studied.(4)Take a city as an example,based on the engineering optimization work.Theactual site is used to verify the optimization of site interference,site coverage and site switching.Has the reference and the research nature,has provided the good reference value for the personnel which is engaged in the engineering optimization work.Through this study,I hope to be able to make a demonstration and reference for operators' operation and maintenance personnel engaged in TD-LTE engineering optimization.Through the attention and strengthening of engineering optimization.Comprehensively improve the quality of TD-LTE's 4G base station network access,accelerate the efficiency of network construction,and reduce the optimization cost.Make the 4G coverage of our country reach a higher level,replace the traditional 2G and 3G networks,and serve the whole people with higher quality.
