"One of the main objectives of Heterogeneous Wireless Access Networks (HWANs) is to integrate the different wireless access technologies, such as UMTS, WiMAX and WLAN, with a common IP-based network in order to offer mobile users continuous and unified service in a transparent way. However, one of the major issues is to support end-to-end QoS across all these technologies at all stages of the service from set-up to handoff. The authors present, in this paper, a novel method of mapping QoS of UMTS and WiMAX over a loose coupling environment across IP/DiffServ network."
