Abstract

In UMTS radio access networks (UTRAN), the delay requirement - bandwidth product of real-time classes is small, therefore large packets need to be segmented. Furthermore, low priority segmented packets may also have real-time requirements. Assuming that UTRAN traffic is characterized as the superposition of periodic sources with random offset, we propose analytic results and we show simulation results for the delay distribution of real-time classes in a priority system. We then compare segmentation methods considering the delay requirements of all real-time classes.
