使用OMC度量的3G和4G无线网络中的业务热点定位

Traffic Hotspot localization in 3G and 4G wireless networks using OMC metrics

摘要:

近年来,由于具有小小区部署的异构网络(HetNet)和绿色网络的出现,人们越来越意识到流量定位技术。以非常高的准确度定位热点数据业务对于了解小型小区应该部署在哪里以及如何管理睡眠方式概念确实非常有意义。在本文中,我们提出了一种新的流量定位技术的基础上,不同的关键性能指标(KPI)提取的操作和维护中心(OMC)的组合。建议的定位算法由五个主要步骤组成,每个步骤对应于每个区域的流量权重的确定,只使用一个KPI。这些KPI是定时提前(TA)、到达角(AoA)、相邻小区水平、每个小区的负载以及调和平均吞吐量(HMT)与算术平均吞吐量(AMT)。五个KPI最终由一个函数组合,该函数将从五个步骤计算的值作为变量。通过混合这样的KPI,我们表明,它是可能的,以减少显着的定位误差在一个高精度实现小细胞尺寸。

英文摘要:

In recent years, there has been an increasing awareness to traffic localization techniques driven by the emergence of heterogeneous networks (HetNet) with small cells deployment and the green networks. The localization of hotspot data traffic with a very high accuracy is indeed of great interest to know where the small cells should be deployed and how can be managed for sleep mode concept. In this paper, we propose a new traffic localization technique based on the combination of different key performance indicators (KPI) extracted from the operation and maintenance center (OMC). The proposed localization algorithm is composed with five main steps; each one corresponds to the determination of traffic weight per area using only one KPI. These KPIs are Timing Advance (TA), Angle of Arrival (AoA), Neighbor cell level, the load of each cell and the Harmonic mean throughput (HMT) versus the Arithmetic mean throughput (AMT). The five KPIs are finally combined by a function taking as variables the values computed from the five steps. By mixing such KPIs, we show that it is possible to lessen significantly the errors of localization in a high precision attaining small cell dimensions.
