QoS evaluation in a UMTS cell

The objective of this work is to evaluate the Quality of Service (QoS) of a Universal Mobile Telecommunication System (UMTS) cell. Among UMTS characteristics, we focus the attention on two aspects strictly related with the identified 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 mobile telephone operators'one.
