Title
(EN) REDUCTION OF CONTROL CHANNEL TRAFFIC
(FR) REDUCTION DU TRAFIC SUR LES CANAUX DE COMMANDE
Abstract
(EN)
A radio communication system has means for enabling the control channels associated with a data channel transmitting packet data with a low duty cycle to be switched to a dormant state or interrupted entirely. This reduces the excessive overhead that such control channels represent on a data channel only using a small proportion of the available channel capacity.
(FR)
L'invention porte sur un système de radiocommunications présentant un moyen permettant de faire passer à l'état de veille ou d'interrompre totalement les canaux de commande à faible taux d'utilisation associés à un canal de données transmettant des données en paquets. On réduit ainsi les frais excessifs que représentent de tels canaux de commande sur un canal de données alors qu'on utilise seulement une faible proportion de la capacité disponible du canal.
