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.
