In the literature distributed call admission control (CAC) schemes exist in which, an infeasible call is rejected early and incurs only a small disturbance to existing calls, while a feasible call is admitted and the system converges to the Pareto optimal power assignment. However, these schemes exist only for unconstrained systems (systems that have no constraint on maximum transmitted power level). In practical systems, a power constraint exists in both uplink and downlink. In this paper we propose a method by which an incoming call whose inclusion in the system can force one of the existing calls to violate the maximum power constraint, is rejected. This method can be used at call admission stage in practical systems which are power constrained. Simulation results have been provided.
