Challenges for Quality of Service in Next Generation Mobile Networks

Overview Next generation mobile networks, commonly referred to as 4G, are envisaged as a multitude of heterogeneous systems interacting through a horizontal IP-centric architecture. This paper presents an overview of the issues arising in such hybrid systems and international research work, with particular emphasis on Quality of Service (QoS) and vertical handoff. An outline of the research is presented, that is, optimising the handover process in proportion to both delay and throughput, by measuring QoS parameters and link characteristics at appropriate places in the networks, and drawing out decisions upon the profitability/necessity of a vertical handoff.
