LTE覆盖优化中引入小区贡献度的分析方法研究

LTE Coverage Optimization into Small Contribution in the Analysis Method

在LTE网络覆盖优化中,由于LTE网络是宽带宽同频组网,随着用户的增长,重叠覆盖区域的干扰会越强,因此,在网络建设初期,就要未雨绸缪,要重视网络覆盖的精确性,使每个小区的覆盖范围准确,同时要尽量减少对周边其他小区的干扰显得非常重要。要达到此目的,常规的分析方法存在各种各样的局限性,因此,我们在覆盖优化中引入"小区贡献度的分析方法",以对4G网络的覆盖类问题进行分析优化。"小区贡献度分析方法"就是我们依据测试数据中的某个小区作为主邻接小区的采样点数量、经纬度、SINR及RSRP等因素作为评估因素,编制的一种评估小区覆盖重要性或者贡献度的宏工具,将原始数据导入该工具并运行,就能直观地定位统计出覆盖类问题的小区,这样可以突破常规的路面问题分析方法,为小区级的覆盖问题分析提供多维的分析手段,提升覆盖问题分析优化的效率及精准度。

In LTE network coverage optimization, LTE network is due to the wide band network in same frequency network, along with the growth of user overlapping coverage interference will be stronger, therefore, in the early stage of network construction, To achieve this purpose, the conventional analytical methods exist all sorts of limitations, so we in coverage optimization into small contribution in the analysis method, to the 4G network coverage problem optimization analysis. ＂Small contribution degree analysis method＂ is we according to the test data of a cell as the main adjacent cell sampling number and the latitude and longitude, SINR and rsrp factors as evaluation factors, preparation of a kind of assessment area covered by the importance degree of contribution or macro tool, primitive data were imported into the tool and operation, will be able to visually locate statistics class cover problem areas, for coverage of district level analysis provides multidimensional analysis means, enhance the coverage problem analysis to optimize the efficiency and accuracy.
