基于自组织网络的LTE RACH优化技术研究

摘要

LTE RACH optimization technology based on self-organizing network was discussed in this paper. Specifically, the basic requirements, influencing factors, self-organizing network architecture and processing methods of RACH optimization were taken into consideration to improve the performance, operation and maintenance cost of LTE network. Based on statistics and measured data of eNodeB and UE, the automatically triggered RACH optimization can be realized.%通过对基于自组织网络的LTE RACH自优化技术进行研究，包括RACH自优化的基本需求和影响因素、实现RACH自优化功能的自组织网络架构和RACH自优化处理方法，以提高LTE网络性能和降低运维成本。基于eNodeB和UE的统计及测量数据，可以在无人工干预的情况下自动触发RACH的优化。
