Résumé: A mobility-aware call admission control (CAC) strategy for capacity optimization in mobile wireless communication systems is proposed. In the strategy, calls by slow moving users are intentionally dropped in a controlled manner to increase channel utilization. Results show that our CAC achieves 23.3% and 5.56% capacity gain relative to the Non Priority and Fractional Channel Reservation (FCR) strategies, respectively.
