The disclosure provides a method, device and system for controlling UE to take measurements, the method comprising: a radio network controller sending an ANR measurement configuration message to UE, wherein the information carries the maximum time that the UE is to take ANR measurements; the UE receiving the ANR measurement configuration message, taking the ANR measurements, timing a measurement period, and storing the measurement results; when the measurement period reaches the maximum time, the UE deleting the ANR measurement configuration message. The disclosure solves the problem of lack of specific procedure about whether UE needs to continue taking measurements and how the measurements should be taken when there is no qualified information after a long period of measurement, thereby preventing the UE from constantly being in a measurement mode, and saving resources.
