Admission control for differentiated services in 3G cellular networks

Third generation wireless systems can simultaneously accommodate flow transmissions of users with widely heterogeneous applications. As radio resources are limited, we propose an admission control rule that protects users with stringent capacity requirements (“streaming traffic”) while offering sufficient capacity over longer time intervals to delay-tolerant users (“elastic traffic”). Using time-scale decomposition, we develop approximations to evaluate the performance of our differentiated admission control strategy to support integrated services with capacity requirements in a realistic downlink transmission scenario for a single radio cell.
