Abstract—The increasing uptake of Internet of Things (IoT),
Big data and cloud-based services introduces a new set of
requirements for network performance. Furthermore, the
evolution of mobile networks towards an all-IP 4G LTE
introduces new challenges for traditional voice and data services.
It is critical for operators to guarantee minimum levels of
performance. Therefore, operators need to understand and
manage both quality and performance of the services to fulfill on
the technical quality of service (QoS) as well as on the quality of
experience (QoE) level. 4G LTE broadband mobile technologies
have been designed with different QoS (Quality of Service)
frameworks to enable delivery of the evolving Internet
applications. Specifically, it is fundamental requirement to
provide satisfactory service delivery to users and also to manage
network resources. To provide QoS, different service levels are
specified for different types or stream of traffic in term of
throughput, latency (delay), jitter (delay variation) and packet
errors or loss. This paper aims to provide a basic principle of
QoS of the 4G LTE service. The impact of QoS parameter on
QoE such as real-time and video communication services is
discussed in this paper. QoS for 5G and M2M networks is also
discussed in this paper as a future research.
Index Terms—Quality of service (QoS), quality of experience
(QoE), 4G, LTE, mobile, subscriber.
