A channel power control method in fast-speed data entering system sets up an offset power of DPCH emissino power and different emission power corresponded to DPCH HI and HS-sCCH under non-soft switching state of UE, sets up a target signal to noise ratio of DPCH HI, a variation threshold value of DPCH HI signal to noise radio, and an offset power of HS-SCCH emission power and DPCH HI emission power under soft switching state of UE. When UE is under the state of non-soft switching state, emission power of HS-SCCH and DPCH HI is determined by the applying method of DPCH emission power plus offset and power control of HS-SCCH, and DPCH HI is finalized by the applying method of sending power control command according to the channel condition to DPCH HI, when UE is under the state of soft switching. |
