Claim:
1. A macro base station to micro base station switching method, comprising: multiplexing part of scrambling codes in reserved scrambling codes to micro base station cells and configuring multiplexed scrambling code information to a user equipment; in accordance with existing determined neighbor cell relations as well as cell synchronization information in a measurement report reported by the user equipment, a network side creating a system frame number-system frame number (SFN−SFN) relation list between various base station cells, wherein the created SFN−SFN relation list comprises SFN−SFN offsets between macro base stations and micro base station cells as well as micro base stations and micro base station cells; when the user equipment reports a switching measurement report of a target cell, the network side determining a target cell in actual switching and performing a corresponding switching action according to scrambling code information in the switching measurement report, TM and OFF information in the cell synchronization information and the SFN−SFN relation list; wherein the process of the network side determining the target cell in actual switching according to the scrambling code information in the switching measurement report, the TM, OFF information in the cell synchronization information as well as the SFN−SFN relation list is as follows: composing cells corresponding to a value of scrambling code into a cell list according to the value of scrambling code in the measurement report reported by the user equipment; calculating a SFN−SFN difference between the target cell and a source cell according to values of TM and OFF of the target cell of the switching measurement report reported by the user equipment; calculating SFN time differences between various cells in the cell list and a source cell Cell wherein SFN TargetCell DeltaFrame is a configured allowed SFN time difference.
