Quality-driven mobility management with a network information service

Abstract

Data traffic over mobile networks is growing substantially and pose increased challenges for both end systems and networks to satisfy the required service levels of different applications. Currently, mobility management is based on signal-strength-based analysis, although for end-users, the Quality of Experience (QoE) and the underlying Quality of Service (QoS) would be the most meaningful criteria for triggering handovers and selecting target base stations. In this demonstration, we present a network information service that helps mobile devices find networks and base stations that not only cover their current location but also satisfy their application QoS requirements. End systems perform QoS measurements in real time and feed the information service with results. Through a single query to the information service end systems can find a sufficient amount of information about networks and base stations in range to make handover target decisions on QoS basis.
