Analysis and taxonomy of network quality of service (QoS) concepts in the long term evolution/system architecture evolution (LTE/SAE) System

摘要

[Abstract]: Modern mobile communication networks provide a variety of voice and data services. These services have different Quality of Service requirements and priorities. The latest set of mobile technology specifications by the 3rd Generation Partnership Project is referred to as Long Term Evolution/System Architecture Evolution. Theseud4th generation systems’ features major changes in access and core network as well as service delivery. The main aim of this project is to investigate performance of the Quality of Service concept of these systems. This includes an analysis of the categorisation of the available Quality of Service mechanisms. In particular, the project investigates and evaluates the performance features of the network. These performance features include packets’ delay and downstream throughput. Better performance of loaded network in the presence of Quality of Service mechanism isudone of the main goals of this project. More specifically, speed-up real-time packets as they are the highest delay sensitive packets. Network simulator, NS2, is used to emulate a LTE/SAE network and to simulate traffic. Simulation results show that the throughput and delay of real-time packets are improved in the existence of Quality of Service mechanism.
