High Speed Packet Access est une fusion de l'accès par paquets de liaison descendante haute vitesse (HSDPA) et de l'accès par paquets de liaison montante haute vitesse (HSUPA), qui étend et améliore les performances des réseaux de télécommunication mobiles utilisant les protocoles WCDMA. HSDPA permet des débits de données plus élevés grâce à de nouvelles techniques de modulation et de codage adaptatives, à l'algorithme hybride de répétition automatique et à l'algorithme de planification rapide. L'une des principales caractéristiques de HSDPA est de gérer les classes de trafic UMTS avec différentes exigences de QoS. Afin de fournir QoS, plusieurs algorithmes de planification, contraintes de contrôle QoS, et différents autres schémas ont été proposés dans la littérature. Dans ce livre, un modèle sophistiqué pour HSDPA est présenté pour simuler divers algorithmes. Les contrôles QoS en termes de débit garanti ont été mis en œuvre au moyen de fonctions de barrière qui effectuent une barrière autour de la zone réalisable. Les résultats illustrent le compromis entre le débit cellulaire et le débit binaire minimum garanti. Les classes de trafic sont priorisées au moyen de paramètres QoS. La priorité est donnée aux flux de trafic RT sur les services interactifs. Des algorithmes en temps réel ont été simulés pour hiérarchiser les classes de trafic en fonction des retards.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -High Speed Packet Access is an amalgamation of High Speed Downlink Packet Access (HSDPA) & High Speed Uplink Packet Access (HSUPA), that extends & improves the performance of mobile telecommunication networks utilizing the WCDMA protocols. HSDPA allows for higher data rates due to new adaptive Modulation and Coding techniques, Hybrid Automatic Repeat reQuest & fast scheduling algorithm. One of the key features of HSDPA is to handle UMTS traffic classes with different QoS requirements. In order to provide QoS several scheduling algorithms, QoS control constraints, & different other schemes have been proposed in literature. In this book, a sophisticated model for HSDPA is presented to simulate various algorithms. The QoS controls in terms of guaranteed bit rate have been implemented by means of barrier functions which perform barrier around the feasible region. The results illustrate the trade-off between the cell throughput & the minimum guaranteed bit rate. Traffic classes are prioritized by means of QoS parameters. The priority is given to RT traffic streams over interactive services. Real-Time algorithms have been simulated to prioritize traffic classes based on delays. 108 pp. Englisch.
