Optimización de la calidad de experiencia en redes LTE mediante el reparto de tráfico

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 traffic steering a key use case. Traditionally, traffic steering aims to balancing the traffic among adjacent cells, although it has also been used to balancing QoE among cells in a LTE network. Nevertheless, these techniques may fail when pursuing maximum user QoE. In this work, a novel traffic steering algorithm is proposed to reach maximum QoE in a realistic LTE network with a file download service
