|
In next generation heterogeneous wireless networks, a user with a multi-mode terminal may have different bearer services using different access technologies. Various approaches can be applied to improve user QoS, such as bandwidth degradation for real-time services, integration of real-time and data traffic, and overflow traffic in overlay networks. In this paper, new techniques are derived to analyse real-time and data traffic performances in wireless networks, revealing the different influences of mobility on real-time and data traffic. In addition, simulations have been carried out to study the performance of the joint allocation and overflow control of real-time and data traffic. A simple bearer service allocation policy is proposed, which not only maximizes network capacity and increases user QoS, but also simplifies overflow management.
