Worldwide Interoperability for Microwave Access (WiMAX) is considered a cost-effective way to provide wireless access to an Internet protocol (IP) Multimedia Subsystem (IMS)-based core network. Determining how to provide end-to-end quality of service (QoS) for the applications indicated is a significant issue. This article highlights the IMS over WiMAX framework and proposes a layered QoS model with feasible signaling flow. Several techniques are analyzed, especially cross-layer QoS mapping and an end-to-end QoS provisioning signaling mechanism. © 2007 Alcatel-Lucent.
