Embodiments of the present invention provide an outer loop power control method, apparatus and device. The outer loop power control method in the present invention includes: determining, according to a target value of each control channel performance indicator of user equipment UE in each cell, a target value of at least one performance mapping indicator of the UE, where the performance mapping indicator includes: a pilot signal bit error rate, a reference signal bit error rate, and a control channel reference measurement miss detection probability; acquiring a measured value of the at least one performance mapping indicator of the UE; determining a signal-to-noise ratio target value of the UE according to the target value of the at least one performance mapping indicator of the UE and the corresponding measured value of the performance mapping indicator; and performing outer loop power control on the UE according to the signal-to-noise ratio target value of the UE, so that after the outer loop power control, a measured value of the at least one performance mapping indicator reaches the corresponding target value of the performance mapping indicator. In the embodiments of the present invention, the signal-to-noise ratio target value is controlled according to CCH quality, and precision for controlling the signal-to-noise ratio target value is improved. |
