Implementation and evaluation of an end-to-end IP QoS architecture for networks beyond 3rd generation

This paper describes a global end-to-end Quality of Service architecture for Beyond-3G networks. This "All- IP" architecture supports multiple access networks technologies (WCDMA, WLAN and Ethernet), and interoperates with Mobility and Authentication, Authorization, Accounting and Charging (AAAC) systems. The different network entities involved in the overall QoS delivery process are introduced. Additionally, scenarios and signaling mechanisms for providing peruser and per-service QoS as well as resource management functionalities integrated in Access Routers and QoS Brokers are presented.
