Interference management method and system in heterogeneous network and home base station

The invention discloses an interference management method and an interference management system in a heterogeneous network. The interference management method comprises the following steps of: pre-configuring more than one carrier wave for a macro-cellular base station, wherein different carrier waves correspond to different coverage areas; respectively detecting reference signal energy which areon the different carrier waves and from the macro-cellular station by a home base station, and determining the coverage area in which the home base station is located according to detection results; and determining that the carrier wave corresponding to the coverage area is a low priority carrier wave, determining that the remaining carrier waves are high priority carrier waves, and preferably using the high priority carrier waves. The invention simultaneously discloses the home base station. By adopting the scheme disclosed by the invention, mutual interference between the macro-cellular base station and the home base station can be reduced.
