End-to-End Quality of Service Provisioning for Internet Access via Third Generation Wireless Networks
並列摘要
Large bandwidth, guaranteed quality of service (QoS), and ease of deployment, coupled with great advancements in semiconductor technologies for wireless devices make third generation (3G) wireless networks a very attractive solution for mobile users to access the Internet. 3G wireless networks will support interactive multimedia services, so QoS support is crucial. In this paper, we briefly survey 3G network architecture and specifications for supporting QoS, using UMTS as a specific example. We also identify the problems of end-to-end QoS provisioning in the context of UMTS interworking with other public networks that form the Internet. To address these problems, we present potential solutions based on existing Internet QoS provisioning schemes.
