Résumé: Handover blocking of ongoing calls due to the mobility of users is a quantity that determines at most the Quality of Service (QoS) in microcellular and picocellular G3G systems environments. In this paper we propose a call admission policy, based on the fractional guard channel scheme, which additionally considers the blocking of new calls. Simulation results show that the proposed policy gives an improved system performance, compared to the most commonly used handover algorithms.
