Architecture for 3G and 802.16 wireless networks integration with QoS support

To meet the growing demand for broadband wireless connectivity, integrating 3G and IEEE 802.16 networks is a clear and viable solution. To the best of the authors´ knowledge, this is the first solution proposed for the integration of 3G and 802.16 wireless networks. We present a novel network and mobile client architecture that provides seamless roaming and mobility while maintaining connectivity across these heterogeneous wireless networks and provides quality of service (QoS) support. To provide QoS support to the application in the integrated network environment, the proposed architecture incorporates the procedures for activating a QoS session, the translation between network-specific QoS classifications, and network and session layer QoS support. We provide simulation results that show the viability and performance of the proposed QoS architecture
