Abstract

A transmission rate control method for controlling, at a mobile station, a transmission rate of uplink user data, based on a dedicated absolute transmission rate of uplink user data received via a dedicated E-AGCH which is transmitted using a dedicated identifier for the mobile station or a common absolute transmission rate of uplink user data received via a common E-AGCH which is transmitted using a common identifier for mobile stations which satisfy a predetermined condition, includes: storing, at the mobile station, the common absolute transmission rate of the uplink user data received via the common E-AGCH; and deleting, at the mobile station, the stored common absolute transmission rate of the uplink user data when changing a serving cell for the mobile station.

Claims4

Dependent claims

A transmission rate control method for controlling, at a mobile station, a transmission rate of uplink user data, based on a first absolute transmission rate of uplink user data received via a first absolute transmission rate control channel which is transmitted using a first identifier for the mobile station or a second absolute transmission rate of uplink user data received via a second absolute transmission rate control channel which is transmitted using a second identifier for mobile stations which satisfy a predetermined condition, comprising:

storing, at the mobile station, the first absolute transmission rate of the uplink user data received via the first absolute transmission rate control channel;
storing, at the mobile station, the second absolute transmission rate of the uplink user data received via the second absolute transmission rate control channel;
and
deleting at the mobile station, the stored second absolute transmission rate of the uplink user data when changing a serving cell for the mobile station, based on a command from a radio network controller.
