This talk is aimed to cover my work done in simulating the network performance achieved by Telia Denmark’s LTE network for individual data services, in terms of service based QoS parameters that give insight on user experience. This is the work for my Master thesis at DTU.
QoS is the ability of a network to provide satisfactory performance in terms of delay, jitter, packet loss etc., for different traffic types, ranging from video conversation to web browsing. However, QoS in a network is not straightforward to provide or measure. Due to the difficulty in providing a QoS acceptable to both customers and the providers themselves, ISPs employ several QoS measuring mechanisms in different parts of the end-to-end mobile network. However, the average of a QoS parameter, like, the average web page download time achieved by the network will not reflect accurately the Quality of Experience (QoE) of an individual user. QoS is an objective measurement and it can be: Network based, for example, handover failure rate, Service based, for example, voice call speech quality. QoE, on the other hand, is a subjective measurement of how well the network is satisfying the user’s requirements. Thus, the goal of the thesis was: A service based analysis of the end-to-end QoS provided by the LTE network for individual services like web browsing, file transfer, video conferencing etc.The simulations analyse the network performance for different queuing profiles. The presentation covers the simulation tool used, network under consideration, the different simulation scenarios, results for different queuing profiles, and, concludes with demonstating how simple QoS configurations will improve the data quality for ISPs.
