Abstract:
1. A mobile communication method by which a mobile station transmits uplink user data at a transmission rate corresponding to a granted value notified to the mobile station by a cell under control of a radio base station, the method comprising: causing the cell under the control of the radio base station to determine an initial granted value when an uplink user data transmission channel is set up between the mobile station and the cell under the control of the radio base station; causing the cell under the control of the radio base station to notify a radio network controller of the initial granted value determined; causing the radio network controller to notify the mobile station of the initial granted value notified by the cell under the control of the radio base station; and causing the mobile station to transmit the uplink user data via the uplink user data transmission channel at the transmission rate corresponding to the initial granted value notified by the radio network controller, after the uplink user data transmission channel is set up, until the mobile station receives the granted value notified by the cell under the control of the radio base station, wherein the cell under the control of the radio base station sets the initial granted value to be equal to the granted value used in transmitting only a single data unit on the uplink user data transmission channel.
