This is an excellent paper to give an introduction to QoS architecture of
3G systems.

Abstract:
The third generation networks and services present opportunities to offer
multimedia applications and services that meet end-to-end quality of service
requirements. The key parts of the standards are already in place, and
limited 3G services have already been turned on. While the evolution to 3G
occurs, many operators will implement 2.5G interim solutions for a good
period of time. In this article we briefly discuss the various evolution
scenarios from the present 2G networks to 3G networks. Then we present the
UMTS QoS architecture and its requirements, followed by a discussion on QoS
in 3G air interfaces, radio access network, and core network.
