(EN) BASIC QUALITY OF SERVICE (QOS) MECHANISMS FOR WIRELESS TRANSMISSION OF IP TRAFFIC
(FR) MECANISMES QUALITE DE SERVICE DE BASE POUR TRANSMISSION SANS FIL DE TRAFIC IP
Abstract
(EN)
IP packets classified according to QoS are mapped onto radio bearers according to various mechanisms. Packets arriving at or leaving from a first network are checked to see if an indicated QoS has been achieved in transit before arriving or leaving and, if not, degrading the QoS actually allocated accordingly for purposes of further transmission.
(FR)
L'invention concerne des paquets IP classés en fonction de la qualité de service, qui sont appliqués sur des dispositifs avec radio selon divers mécanismes. Les paquets arrivant à un premier réseau ou quittant ce dernier sont vérifiés afin d'établir si une qualité de service indiquée a été ou non réalisée en transit avant l'arrivée ou le départ et, dans la négative, on dégrade la qualité de service effectivement accordée en conséquence aux fins d'une nouvelle transmission.
