UMTS - Random Access Procedure - Admission Control Stochastic Activity Network - Simulation - QoS Analysis.


The objective of this work is to evaluate the Quality of Ser vice (QoS) of a Universal Mobile Telecommunication Sys tem (UMTS) cell. Among UMTS characteristics, we focus the attention on two aspects strictly related with the iden tified QoS measures: the random-access procedure and the admission control strategy. Using a model-based approach, we model and evaluate a UMTS cell under several service classes, thus providing useful insights on the perception of the QoS both from the users’perspective and from the mo bile telephone operators’one.
