Abstract

We propose a QoS Based call admission control (CAC) scheme designed for multiclass cellular networks. The scheme allocates the portions of the channel capacity to individual traffic classes, and by monitoring the call arrival patterns periodically updates the share of each class. For each traffic class, it treats new and handoff calls separately to keep the drop probability of handoff calls as small as possible to maintain the user satisfaction at a high level. Our modeling study and analysis show that the CAC mechanism is capable of both satisfying the Quality of Service requirements of multiple traffic classes while optimizing the system utilization.
