This paper provides a study of threshold-based call admission control in CDMA systems. We formulate a framework, in which the existing algorithms are identified and even original ones can be developed with similar concepts. Different schemes are compared under the point-of-view of quality of service metrics, like blocking and dropping probability. A general trade-off can be shown, that can be managed in a simple but effective way by setting the admission threshold appropriately. As a final contribution, we propose possible extensions that, if included in the presented framework, can be beneficial for the admission control performance.
