Abstract :
In this paper, we investigate two approaches to handle UMTS traffic classes at the AAL2 and ATM layer over the Iub and Iur interfaces in the UMTS Terrestrial Radio Access Network (UTRAN). The first method is proposed to improve the (AAL2-) CPS scheduler by introducing the notion of traffic priority. The second method consists of multiplexing each UMTS traffic class into separate ATM connections with specific QoS. We present some simulation results on ATM/AAL2 performance to evaluate the two methods in terms of mean transmit delays, bounds of transmit delay and bandwidth efficiency
