The present invention relates to a mobile communication system which applies a high-speed downlink packet transmission scheme (HSDPA scheme) in a downlink and an enhanced uplink packet transmission scheme (EUL scheme) in a uplink between a mobile station and a base station. In the mobile communication system according to the present invention, a serving cell in the high-speed downlink packet transmission scheme for a specified mobile station and a serving cell in the enhanced uplink packet transmission scheme for the specified mobile station are modified so as to become the same cell.

The present invention relates to a transmission rate control method for controlling a transmission rate of user data to be transmitted via an uplink by a mobile station. A radio network controller notifies an initial maximum allowable transmission rate of the user data to the mobile station, when a serving cell of the mobile station is to be changed. The mobile station increases the transmission rate of the user data up to the initial maximum allowable transmission rate notified from the radio network controller automatically, while the serving cell is being changed. The mobile station increases the transmission rate of the user data up to a maximum allowable transmission rate in the changed serving cell of the mobile station automatically, after the serving cell has been changed.

It is an object of the present invention to perform a soft handover control in which an error rate is low in the Enhanced Uplink. A mobile communication control method according to the present invention includes the steps of: performing a change control for a transmission rate of uplink data to be transmitted from a mobile station UE to a first base station Node-B #1, while the first base station Node-B #1 and the mobile station UE are communicating with each other; determining that the mobile station UE is to perform soft handover between the first base station Node-B #1 and a second base station Node-B #2; instructing the first base station Node-B #1 and the mobile station UE to stop the change control for the transmission rate of the uplink data; and instructing the mobile station UE and the second base station Node-B #2 to start the soft handover.

The present invention can flexibly adjust trade-off between the radio network capacity and the radio quality by changing increase step of uplink user data in accordance with the congestion of uplink or the uplink user data type. A transmission rate control method according to the present invention includes the steps of; notifying, at a radio network controller RNC, an increase pattern of the transmission rate of the uplink user data to a mobile station UE, when setting, with the mobile station UE, a user data channel connection for transmitting the uplink user data and increasing, at the mobile station UE, the transmission rate of the uplink user data in accordance with the increase pattern, when receiving, from a radio base station Node B, a relative rate control channel RGCH for indicating that the transmission rate of the uplink user data should be increased.

A mobile communication method according to the present invention includes: transmitting, from a mobile station, a retransmission-control applied dedicated physical data channel to which a retransmission control processing is applied and which is configured not to contain any transmission data blocks, when there is no transmission data block that should be transmitted, at a predetermined cycle, with a transmission power having a predetermined offset relative to a transmission power of a dedicated physical control channel; generating, by a radio base station, transmission power control information for controlling a transmission power of the dedicated physical control channel, by a closed-loop power control based on a reception quality of the dedicated physical control channel, and by an outer-loop power control based on a reception quality of the retransmission-control applied dedicated physical data channel, and transmitting the transmission power control information to the mobile station; and determining, by the mobile station, the transmission power of the dedicated physical control channel, based on the transmission power control information, and transmitting, from the mobile station, the dedicated physical control channel to which the re-transmission control processing is not applied with the determined transmission power.

A transmission rate control method for controlling a transmission rate of uplink user data to be transmitted by a mobile station, includes: determining, at the radio network controller, that the mobile station is shifted between a soft-handover state in which the mobile station establishes radio links with a plurality of cells and a non soft-handover state in which the mobile station establishes a radio link with only one cell; allocating, at the radio network controller, a first temporary identifier or a second temporary identifier as a common identifier for a common transmission rate control to the mobile station based on the determination of shifts; and controlling, at a cell which establishes a radio link with the mobile station, the transmission rate of the uplink user data of the mobile station using the first temporary identifier or the second temporary identifier.
