Abstract

In this paper we develop a call level model of UMTS core networks where calls belonging to one of the four UMTS service classes arrive randomly. Arriving calls are granted service depending on the call's service class, the required maximum- and minimum bandwidth, and the available network resources at the arrival instance. We use a Markov model of transmission links to derive GoS (blocking probability) and QoS (throughput) measures under two reasonable and technologically feasible bandwidth sharing policies. We conclude that one of these policies is able to provide GoS/QoS guarantees for a wide range of traffic mixes. We argue that the results are applicable to the all-IP/MPLS based new UMTS architecture. 3rd generation mobile networks, UMTS networks, bandwidth sharing objectives, multi-rate loss models, blocking probabilities, Markov models.
