Increment steps of upstream user data are changed in accordance with the uplink traffic status and/or the types of the upstream user data, thereby flexibly adjusting the tradeoff between the radio channel capacity and the radio quality. A transmission rate control method comprises a step in which when establishing the connection of a user data channel, on which upstream user data is transmitted, to a mobile station (UE), a radio channel control station (RNC) notifies the mobile station (UE) of an increment pattern of the transmission rate of the upstream user data; and a step in which when receiving, from a radio base station (Node B), a relative rate control channel (RGCH) indicative of the necessity of increasing the transmission rate of the upstream user data, the mobile station (UE) increases the transmission rate of the upstream user data in accordance with the increment pattern notified of.

Selon l~invention, les étapes d~incrémentation des données utilisateurs montantes sont changées en fonction de l~état du trafic montant et/ou du type des données utilisateur montantes, adaptant ainsi de façon flexible le compromis entre la capacité du canal radio et la qualité radio. L~invention concerne un procédé de contrôle de vitesse de transmission comprenant une étape lors de laquelle, en établissant la connexion d~un canal de données utilisateur, sur lequel les données utilisateurs montantes sont transmises, à une station mobile, une station de contrôle de canal radio notifie la station mobile d~un schéma d~incrémentation de la vitesse de transmission des données utilisateur montantes ; et une étape lors de laquelle, lors de la réception, depuis une station de base radio (NAEud B), un canal de contrôle de vitesse relative indiquant la nécessité d~une augmentation de la vitesse de transmission des données utilisateurs montantes, la station mobile augmente la vitesse de transmission des données utilisateur montantes en fonction du schéma d~incrémentation notifié.
