Abstract

L'invention concerne un procédé de remise à zéro d'un numéro de séquence de transmission, et un contrôleur de réseau radio. Le procédé de remise à zéro d'un numéro de séquence de transmission comprend : un contrôleur de réseau radio recevant un paquet de données ; le contrôleur de réseau radio estimant si des premières informations de ressources d'accès d'un équipement utilisateur dans le paquet de données concordent avec des secondes informations de ressources d'accès de l'équipement utilisateur conservées dans le contrôleur de réseau radio ; et si ce n'est pas le cas, le contrôleur de réseau radio remet à zéro un numéro de séquence de transmission du paquet de données conservé par celui-ci et correspondant à l'équipement utilisateur. Le procédé permet ainsi que, lorsqu'un équipement utilisateur effectue un nouvel accès et déclenche une nouvelle transmission de données, un contrôleur de réseau radio remette à zéro un numéro de séquence de transmission, ce qui réduit le retard du contrôleur de réseau radio dans le traitement des données.
