Abstract
It is widely recognized that the next-generation wireless networks will integrate heterogeneous wireless technologies. The complementary characteristics of cellular networks and wireless local area networks (WLANs) make the interworking a promising trend. Admission control is one of the essential mechanisms to enhance QoS provisioning in a cellular/WLAN integrated network and utilize the overall resources efficiently. In this paper, we propose an effective admission control scheme for both voice and data services. The admission region is derived, taking into account the two-tier overlay structure, non-uniform traffic distribution and user mobility in the integrated network. The impact of traffic and mobility parameters on the admission scheme is evaluated, which provides some insights for further extension.
