Résumé

Les débits annoncés pour les futures normes de télécommunication, ainsi que le degré d’intégration atteint sont autant de facteurs déterminant pour l’implantation de nouvelles applications dans les terminaux mobiles. Un service mobile de diffusion vidéo en flux est désormais envisageable, d’où l’intérêt d’en assurer la qualité de service nécessaire durant la transmission vidéo. Dans cet article nous proposons un mécanisme de gestion de qualité de service pour optimiser dynamiquement la répartition des débits utilisés dans un réseauUmts. La démarche consiste à formaliser le problème d’optimisation en se basant sur la théorie des graphes et à modéliser le réseauUmts ainsi que les mobiles et les applications utilisées. Les résultats obtenus confirment les performances des fondements de notre approche d’optimisation dans l’amélioration de la qualité de service perçue par l’usager d’un réseauUmts en termes de débit, taux de blocage et taux de coupure de connexion.

Abstract

Bit rate announced for the future standards of telecommunication, as well as the level of integration reached are, as many factors, determining for the establishment of new applications in mobile terminals. Nowadays, mobile video streaming services are possible. Mobile users expect to receive multimedia traffic with some performance guarantees, so we must ensure the necessary quality of service during the video transmission. This paper aims at investigating quality of service issue inUmts network. More specifically, we explore the main challenge of quality of service management to dynamically optimize the distribution of load inUmts networks. Our investigation is organized in the following way. We formalize the optimization problem which is based on the graph theory and modellingUmts network as well as mobile users and applications to be used. The simulation of our optimization model show a clear improvement of the quality of service perceived by anUmts user in terms of bit rate, blocking and connection drop.
