TL;DR: A novel priority-oriented CAC strategy is proposed, based on 3GPP defined QoS classes for multimedia traffic in UMTS, which introduces a QoS renegotiation procedure, resulting in a lower blocking probability for overall traffic.
Abstract: A novel priority-oriented CAC strategy has been proposed in this paper, based on 3GPP defined QoS classes for multimedia traffic in UMTS. The basic idea of our scheme is to let the higher priority class(es) have precedence over the lower priority class(es) at call admission, i.e. the more 'important' calls have more opportunities to be accepted. For delay tolerable classes of traffic, we introduce a QoS renegotiation procedure, resulting in a lower blocking probability for overall traffic. Simulation results under various traffic loads are also presented.
