Una visión basada en QoE para algoritmo MRO en redes LTE

Abstract

Due to the huge increase in traffic and services in mobile networks, network management has changed its main focus from Quality of Service (QoS) to a Quality of Experience (QoE) perspective. In addition, SON (Self organization Networks) techniques have been developed to automate network management, being Mobility Robustness Optimization a key use case. Traditionally, Mobility Robustness Optimization aims to improving Handover performance by reducing too-early, too-late and ping-pong handovers. Nevertheless, these techniques may fail when pursuing maximum user QoE at cell edge. In this work, a novel Mobility Robustness Optimization algorithm is proposed to reach maximum QoE at cell edge in a realistic LTE network with a file download service.
