The invention relates to a method for switching measurement between an RNC control frequency and a system, comprising the following steps: an RNC decides whether to redistribute a traffic channel of a UE according to received measurement report from the UE; and if the RNC decides to redistribute the traffic channel of the UE, the RNC decides which time slot to redistribute the traffic channel of the UE. The method synthetically considers according to signal strength condition of a peripheral cell and a cell reflected in measurement report of the UE, and decides whether to more the channel. If the signal of the UE is strong in the cell or weakens in the cell, but the periphery has other cells with stronger signals, the method can ignore and bear measurement failure during measurement of a target cell; and if the signal of the UE is weak in the cell, and the periphery has no any synchronous cell, or has a synchronous cell, but is not suitable for switching, and the method needs to move the channel of the UE. Therefore, the method can avoid measurement failure, so as to reduce cutting off rate.
