Abstract :
In this paper, we propose a joint uplink/downlink connection admission control scheme in WLAN/cellular integrated systems, where thresholds for admission control are adaptively determined to maximize the network capacity by considering uplink and downlink characteristics in WLAN/cellular integrated systems. The proposed scheme is evaluated by Markov chains in terms of blocking cost. Analytical and simulation results show that the proposed scheme can reduce the number of blocked connections compared with the WLAN-first scheme.
