The next generation wireless network environments are expected to support anywhere, anytime connectivity for high-performance applications. To provide mobile users with seamless wireless access and guaranteed quality of service (QoS), it is a trend to integrate UMTS cellular networks and wireless local area networks (WLANs) into heterogeneous networks in next generation all-IP wireless networks. Access network selection and QoS support for different services are the major challenges in integrated UMTS/WLAN networks. In this paper, we propose a novel access selection method to determine which n...
