Abstract: Future wireless internet will consist of different wireless technologies that should operate together in an efficient way to provide seamless connectivity to mobile users. The integration of different networks and technologies is a challenging problem mainly because of the heterogeneity in access technologies, network architectures, protocols and service demands. Firstly, this paper discusses three architectures for an all-IP network integrating different wireless technologies using IP and its associated service models. The first architecture, called ISB, is based on a combination of Differentiated Services (DiffServ) and Integrated Services (IntServ) models appropriate for low-bandwidth 3G cellular networks with significant resource management capabilities. The second architecture, called DSB, is purely based on the DiffServ model targeted for high-bandwidth wireless LANs with little resource management capabilities. The last architecture, called AIP, combines ISB and DSB architectures to facilitate the integration of wireless LAN and 3G cellular networks towards a uniform architecture for all-IP wireless networks. Secondly, this paper proposes a flexible hierarchical resource management mechanism for the proposed All-IP Architecture (AIP) which aims at providing connection-level Quality of Service (QoS) for mobile users. Simulation results show that the proposed mechanism satisfies the hard constraint on connection dropping probability while maintaining a high-bandwidth utilisation.
