Υποστήριξη Ποιότητας Υπηρεσίας (QoS) και Ποιότητας Εμπειρίας (QoE) σε δίκτυα LTE-A
Translated title:
Support Quality of Service (QoS) and Quality of Experience (QoE) in LTE-A networks
Summary:
The telecommunication sector has grown rapidly in recent years. The
introduction of multimedia and demanding services and the rapid growth of users
require better and guaranteed QoS (Quality of Service, (QoS)) while
continuously monitoring the network and services provided by telecommunications
providers may assess the experience perceived by the end-users (Quality of
Experience, (QoE). Recently the 3GPP (3rd Generation Partnership Project)
developed the LTE-A (Long Term Evolution-Advanced) network to achieve 4G
requirements as defined by ITU-R in IMT-Advanced. LTE-A aims at providing high
speeds, wide bandwidth usage and increased capacity and performance compared to
existing networks, while the support of QoS and QoE in such networks is an open
challenge. This thesis studies ways to support QoS and QoE network in LTE-A
networks. First, a brief historical review of telecommunications systems is
provided leading to the description of the LTE-A network. Considering the QoS,
the key role of the operating Policy control and charging rules function (PCRF)
backbone network of LTE-A is studied in detail. To assess and delivery high QoE
in LTE-A all the necessary information related directly or indirectly to the
QoE managed at a central point in the network, which collects performance
indicators and gives commands for QoE-based management.
