Abstract

In this paper, we present a study of admission control in 3G systems. In particular, the behavior of algorithms already presented in the literature is analyzed, with respect to their implementation in UMTS-like systems, and a model of trade-off between the QoS metrics, blocking and dropping probability, is presented. The obtained performance is discussed and analyzed under different points of view. Finally, possibilities to improve fairness and generality of these results open up when a more detailed model for mobility, data rate and discontinuous transmission (DTX) is considered.
