基于用户感知的LTE网络负荷评估体系及扩容研究

Research on Load Evaluation System and Capacity Expansion of LTE Network Based on the User-perceptive Quality

随着LTE网络的迅速发展,用户行为和消费模式发生了改变,对网络带宽的需求不断提升,为了匹配用户业务发展,需研究合理有效的LTE网络负荷评估方法和扩容方案。首先提出基于站点接入能力和用户感知速率2个维度的LTE网络负荷评估体系,根据对LTE现网运行数据分析,获得用户感知受限时网络负荷评估指标的门限值。其次,根据待评估网络小区各项指标统计值与预设门限值的比较结果,判断小区的负荷属性。最后,根据小区负荷属性及各项评估指标的标签,提出有针对性的扩容和优化调整方案。

With the rapid development of LTE network,user behavior and consumption patterns have changed,the demand for network bandwidth continues to increase. In order to match the development of user services,the reasonable and effective LTE net-work load evaluation and expansion scheme is needed. Firstly,the load evaluation system of LTE network based on the two di-mensions of site access capacity and user perception rate is proposed. According to the LTE data analysis,we obtain the threshold value of the user’s perception of the limited network load evaluation index. Secondly,according to the results of the comparison between the statistical values of the network cel and the default threshold,the load attributes of the cel are de-termined. Final y,according to the characteristics of cel load and the evaluation index,targeted expansion and optimization of the adjustment program is proposed.
