Abstract :
In this paper we study the quality of service of integrated voice and data services in a wireless network. The voice traffic is transmitted in circuit-switched mode and data traffic is transmitted in packet-switched mode. We apply a fluid analysis to study the performance of the data buffer under two handoff schemes and the basic system. From this, analysis, we derive admission controls for voice traffic as well as for data traffic. This analysis also enables us to conclude that the reserved channel scheme not only is more effective in reducing the forced termination probability of handoff calls, it is also more effective in providing the QoS guarantee for the data traffic.
