Abstract
Future mobile cellular networks will include complex algorithms and procedures that make them able to react optimally to the fluctuating conditions (propagation, traffic, services, ...). Among these mechanisms, location management is an important one as it deals with an essential function of the mobile cellular networks: locate each subscriber to provide him/her with the subscribed services.
In this paper, we present the location management methods that are currently implemented in cellular networks and the adaptive methods that have been proposed for future mobile cellular networks. These methods are evaluated for different scenarios and their performance are compared by means of simulations.
Résumé
Les futurs réseaux cellulaires de mobiles intégreront de nombreux algorithmes et procédures complexes qui leur permettront de réagir de faÇon optimale à des conditions de fonctionnement fluctuantes (propagation, trafic, services, ...). Parmi ces mécanismes, la gestion de la localisation en est un particulièrement important puisqu’il assure une fonction essentielle dans les réseaux cellulaires: localiser chaque abonné afin de lui assurer les services souscrits.
Cet article présente les méthodes de gestion de la localisation qui sont actuellement implantées dans les réseaux cellulaires ainsi que des méthodes adaptatives proposées pour les futurs réseaux cellulaires. Ces méthodes sont évaluées pour différents scénarios et leurs performances sont comparées par simulations.
