Un contrôle approprié de l'admission des appels dans les réseaux sans fil de prochaine génération devrait permettre une utilisation efficace des ressources sans fil rares et améliorer la qualité de service, tout en prenant en charge les services multimédias. D'une part, bloquer les appels transférés est normalement plus ennuyeux que bloquer les nouveaux appels. D’un autre côté, bloquer les nouveaux appels réduit l’utilisation des ressources. Plus important encore, le taux d’arrivée des appels de transfert dépend fortement de la durée de mise en attente des appels. Un nouveau système de blocage précoce aléatoire basé sur le temps de maintien des appels (CHTREB) est proposé pour atteindre les objectifs susmentionnés dans un réseau cellulaire voix/données à deux niveaux. Avec CHTREB, les nouveaux appels sont acceptés selon une certaine probabilité d'acceptation en tenant compte du décalage horaire entre les appels vocaux et les appels de données. Un algorithme itératif est développé pour calculer des mesures de performance intéressantes, c'est-à-dire la probabilité de blocage de nouveaux appels et la probabilité de terminaison forcée. Tout d’abord, les résultats de simulation sont présentés pour vérifier les résultats analytiques. Ensuite, des résultats numériques sont présentés pour montrer la robustesse de CHTREB. On constate que CHTREB surpasse TR et CHTREB-FAP dans des scénarios de trafic stationnaire et non stationnaire. Enfin et surtout, le système à 2 niveaux étudié est comparé à son homologue à 1 niveau. Il est démontré que le système à 2 niveaux fonctionne mieux en termes de nombre moyen de transferts par appel de données.

Abstract: An appropriate call admission control in the next generation wireless networks is expected to make efficient use of scarce wireless resource and improve quality-of-service, while supporting multimedia services. On one hand, blocking handoff calls is normally more annoying than blocking new calls. On the other hand, blocking new calls reduces resource utilization. More importantly, handoff call arrival rate depends strongly on call holding time. A novel Call-Holding-Time-Based Random Early Blocking (CHTREB) scheme is proposed to achieve the aforesaid goals in a two-tier cellular voice/data network. With CHTREB, new calls are accepted according to some acceptance probability taking into account the call hloding time difference between voice and data calls. An iterative algorithm is developed to calculate performance measures of interest, i.e., new call blocking probability and forced termination probability. First, simulation results are shown to verify analytical results. Then, numerical results are presented to show the robustness of CHTREB. It is found that CHTREB outperforms TR and CHTREB-FAP under both stationary and nonstationary traffic scenarios. Last but not least, the studied 2-tier system is compared with 1-tier counterpart. It is shown that 2-tier system performs better in terms of average number of handoffs per data call.
