In this paper, we propose a resource effective call admission control(CAC) in integrated WLAN and cellular network. The proposed CAC mitigates the congestion of cellular network by handing over non-realtime traffic to WLAN. We analyze the proposed CAC in numerical and simulation method. The simulation results show that the proposed CAC achieves better performance than normal CAC. Especially, the proposed CAC can sustain desired QoS more robustly against high incoming non-realtime traffic load than againt realtime traffic load.
