A Service Admission Scheme for Cellular Networks

In cellular networks, where resources are scarce, the basis for QoS provisioning is to control the admission of new and handoff subscriber services, to avoid future detriment perturbation of established ones. Most research efforts consider only the bandwidth of the wireless link to control the admission of new services. In this paper, we propose a novel approach for service admission that considers, in addition to the station mobility, both bandwidth and error rate requirements as well as the possibility of multiple services per mobile station, while minimizing interference to neighbours cells as well as signalling overhead. When compared to other proposals in a simulated 3G cellular system, our admission control approach outperformed by 7% the equal priority and guard capacities schemes in terms of total number of accepted services in the cell, especially in high handoff and new call rates
