A New Alternative for Traffic Hotspot Localization in Wireless Networks Using O&M Metrics
In recent years, there has been an increasing awareness to traffic
localization techniques driven by the problematic of hotspot offloading
solutions, the emergence of heterogeneous networks (HetNet) with small cells'
deployment and the green networks. The localization of traffic hotspots with a
high accuracy is indeed of great interest to know how the congested zones can
be offloaded, where small cells should be deployed and how they can be managed
for sleep mode concept. We propose, in this paper, a new hotspot localization
technique based on the direct exploitation of five Key Performance Indicators
(KPIs) extracted from the Operation and Maintenance (O&M) database of the
network. These KPIs are the Timing Advance (TA), the angle of arrival (AoA),
the neighboring cell level, the load time and two mean throughputs: arithmetic
(AMT) and harmonic (HMT). The combined use of these KPIs, projected over a
coverage map, yields a promising localization precision and can be further
optimized by exploiting commercial data on potential hotspots. This solution
can be implemented in the network at an appreciable low cost when compared with
widely used probing methods.Comment: Submitted to EURASIP Journal on Wireless Communications and
