On Optimal Admission Control for Multi-Service Cellular/WLAN Interworking

The complementary characteristics of cellular systems and Wireless Local Area Networks (WLANs) make them attractive candidates to jointly offer a seamless wireless solution. In an integrated cellular/WLAN system, the Quality of Service (QoS) requirements for different services (e.g., voice and real-time video) require adequate admission control policies to limit the number of connections in each network. In this paper, the authors analytically develop a comprehensive model to facilitate the optimal evaluation of different admission control policies in a multi-service integrated cellular/WLAN system.
