RILAnalyzer: a comprehensive 3G monitor on your phone

摘要: The popularity of smartphones, cloud computing, and the app store model have led to cellular networks being used in a completely different way than what they were designed for. As consequence, mobile applications impose new challenges design efficient configuration constrained maximize application's performance. Such difficulties are largely caused by lack cross-layer under- standing interactions between entities -applications, devices, network its management plane. In this paper, we describe RILAnalyzer, an open-source tool that provides mechanisms perform analysis from within device. RILAnalyzer is capable recording low-level radio information accurate net- work control-plane data, as well user-plane data. We demonstrate how such data can be identify previously overlooked issues. Through small user study across four providers two European countries infer configurations reality explore interact with application logic, causing energy overheads.
