Method, device and system for controlling user equipment to measure

The invention discloses a method, a device and a system for controlling user equipment to measure. The method comprises the following steps: informing user equipment (UE) by a radio network controller (RNC) to measure automatic neighbor relation (ANR) function; indicating the UE to adopt an event reporting mode; indicating the maximum cell quantity reported by the UE and an ANR measurement threshold; carrying out ANR measurement by the UE; and reporting a measuring result meeting the preset relation with the ANR measurement threshold, wherein the measurement results of M cell are reported each time, and M is not more than the maximum cell quantity. According to the technical scheme provided by the invention, the problem in the prior art that no specific methods can be used for controlling the UE to measure and report is solved, thus the newest cell neighbor relation can be obtained in time, the continuity of the user conversation can be guaranteed, and the service quality of the user can be improved.
