Dans cet article, nous proposons une nouvelle méthode de suivi de localisation pour le transfert de pointeurs avec des schémas HLR distribués afin de réduire le coût de suivi de localisation. Semblable aux schémas HLR distribués, les informations de localisation sont répliquées sur tous les HLR de notre schéma. Cependant, contrairement aux schémas HLR distribués traditionnels, nous propageons les changements de localisation les plus récents à partir d'un HLR pour réinitialiser les pointeurs de transfert dans d'autres HLR, et réduisons ainsi le coût de suivi de localisation pour les livraisons d'appels. Le coût de signalisation de la propagation de localisation peut être trop élevé pour être pratique. Par conséquent, nous autorisons une certaine incohérence entre les données de localisation des HLR et différons la propagation des changements de localisation afin de réduire le coût de propagation. Trois politiques de propagation des délais sont également proposées et analysées par simulation. Le résultat des performances montre que les politiques de propagation de retard réduisent le coût de propagation et que le processus de réinitialisation de la propagation dégrade le coût de suivi de localisation. Notre méthode préserve un faible coût total pour les livraisons d’appels, les enregistrements et les propagations dans les HLR distribués.

Abstract: In this paper, we propose a new location tracking method for pointer forwarding with distributed HLRs schemes to decrease the location tracking cost. Similar to the distributed HLR schemes, the location information is replicated on all HLRs in our scheme. However, unlike the traditional distributed HLR schemes, we propagate the most recent location changes from an HLR to reset the forwarding pointers in other HLRs, and thus reduce the cost of location tracking for call deliveries. The signaling cost of location propagation may be too costly to be practical. Therefore, we allow some inconsistency to exist among the location data of HLRs and defer the propagation of location changes to reduce the propagation cost. Three delay propagation policies are also proposed and analyzed using simulation. The performance result shows that the delay propagation policies reduce the propagation cost and the propagation resetting process degrades the location tracking cost. Our method preserves a low total cost for call deliveries, registrations and propagations in distributed HLRs.
