A Survey on Quality of Service in LTE Networks

Long Term Evolution has being standardized by 3rd Generation Partnership Project (3GPP) in order to fulfil the emergent demand of very high data traffic both in magnitude and variety. In order to fulfil the emerging demand of user LTE networks come into existence with the different characteristics such as high data rate, high coverage area improved latency, high spectral efficiency, low cost and a simplified structure etc. Along with these entire characteristics LTE network may also require some improvement in its service quality. Different methods are recommended in order to improve the QoS. This article presents an overview on 4G LTE system about its architecture, its technologies and its features. Also this article presents the QoS concept in LTE system, QoS parameters and QoS provisioning mechanism in LTE networks.
