基于干扰源定位算法的网络结构优化方法研究

Research of network structure optimization method using interference source location

随着TD-LTE网络负荷不断增大,网络结构问题日益突显,同频干扰日益严重,对用户感知造成了明显影响,因此网络结构专项优化在后期网络维护中越来越重要。传统的网络结构优化方法效率很低,解决一个问题小区需要调整多个邻区。在现网中,如果调整过多的小区,不仅会影响网络的正常运行,而且可能会导致更多新的网络结构问题。本文创新性的提出了一种基于问题区域主干扰源精准定位算法的LTE网络结构优化方法,快速精准定位网络结构问题区域以及区域内的主干扰源,通过调整主干扰源,使得区域内所有被干扰问题小区的指标同时得到明显提升,极大提高了优化质量和效率。

With increasing of LTE network load, the network structure problem and the same frequency interference is becoming more and more obvious, which has bad infi uence on user perception. Therefore, network structure optimization is very important. The traditional method of network structure optimization is very ineffi cient. To solve a problem cell, we need to adjust several neighboring cells. If too many cells are adjusted, it will affect the operation of network, and also lead to more new network structure problems. This paper has provided the network structure optimization method using interference source location, which can quickly and accurately locate the network structure problem area and the main interference source in the region. By adjusting the main interference source, the index of all disturbed cells in the region is improved signifi cantly, and the quality and effi ciency of the optimization are greatly improved.
