Performance Enhancements of UMTS Networks Using End-to-End QoS Provisioning

Tags:
quality of service

Overview This paper investigates end-to-end Quality of Service (QoS) provisioning approaches for UMTS networks in a DiffServ IP network environment. The effort was put on QoS class mapping from DiffServ to UMTS, Access Control, buffering and scheduling optimization. The DiffServ Code Point was utilized in the E2E UMTS QoS provisioning to differentiate different types of traffic. The overall algorithm was optimized to guarantee the E2E QoS parameters of each service class, especially for realtime applications, as well as to improve the bandwidth utilization.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
