Provided are a method and device for controlling transmission power of a user equipment, relating to the field of communications. The method comprises: when the total uplink transmission power of a user equipment (UE) exceeds a maximum allowable transmission power, reducing a gain factor of a first-type channel of the UE, the first-type channel comprising a high-speed packet access channel which comprises a high-speed packet access data channel and a high-speed packet access control channel;and determining the total uplink transmission power of the UE, and if the total uplink transmission power of the UE exceeds the maximum allowable transmission power, and the gain factor of the first-type channel is reduced to a preset gain factor threshold, reducing a gain factor of a second-type channel of the UE, so that the total uplink transmission power of the UE does not exceed the maximum allowable transmission power, wherein the second-type channel comprises a dedicated physical channel, and the dedicated physical channel comprises a dedicated physical data channel and a dedicated physical control channel.The present invention reduces the call drop frequency of CS services and ensures the call continuity between users. |
