Abstract

A dynamic call admission control and resource reservation scheme suitable for CDMA systems is proposed. Preferential treatment is given to high priority calls by preserving an interference guard margin (IGM), which is dynamically adjusted by referencing traffic conditions in neighboring cells based upon users´ quality of service. A comprehensive service model is used including users´ service rates, priority levels, mobility and rate adaptivity. Simulations are conducted by OPNET to study the performance in terms of the objective function under different traffic conditions.
