Abstract :
The focus of this paper is the performance of ATM/AAL2 as a transport technology for Universal Terrestrial Radio Access Network (UTRAN) in UMTS/IMT-2000 setting. In this work, we propose an analytical model for the transparent multiplexing and transport through UTRAN of several voice channels onto a single AAL2/ATM VC. We investigate the queue building up at the AAL2 multiplexer in order to derive some characteristics of the sojourn time of voice frames within the UTRAN. Our results quantify the performance of AAL2/ATM-based transport of voice in terms of mean queue at the multiplexer, mean sojourn time and delay violation probability within the UTRAN.
