Title
(EN) WIRELESS INTERNET TERMINAL AND PACKET TRANSMISSION METHOD FOR IMPROVING QUALITY OF SERVICE
(FR) BORNE INTERNET SANS FIL ET PROCEDE DE TRANSMISSION DE PAQUETS DESTINE A AMELIORER LA QUALITE DE SERVICE
Abstract
(EN)
Disclosed are a terminal of an OFDMA-TDMA wireless Internet system capable of reducing transmission delay time while securing QoS for uplink data and a packet transmission method. A MAC layer (200) of the terminal is divided into a MAC software part (210) and a MAC hardware part (220) to control priorities of data packets at a high level and low level. The high level priority controller (213) carries out various fine control operations according to a QoS policy and the low level priority controller (222) performs mechanical control operations based on a predetermined simple fixed priority policy.
(FR)
L'invention concerne une borne d'un système Internet sans fil OFDMA-TDMA capable de réduire le délai d'attente de transmission tout en sécurisant la qualité de service pour des données de liaison montante et un procédé de transmission de paquets. Une couche MAC de la borne est divisée en une partie logicielle MAC et une partie matérielle MAC afin de commander les priorités des paquets de données à un niveau élevé et à un niveau faible. Le dispositif de commande de priorité à niveau élevé réalise diverses opérations de réglages fins en fonction d'une politique de qualité de service et le dispositif de commande de priorité à niveau faible met en oeuvre des opérations de commande mécanique basée sur une politique de priorité fixe, simple, prédéfinie.
