    Abstract: Disclosed in the present invention are a method, an apparatus and a system for interference management. In the embodiments of the present invention, a Home NodeB (HNB) registers in a macro cell in advance, so that a NodeB Controller (NBC) knows the information of a potential interference source HNB beforehand. Thus simply through a normal measurement and a report subsequently performed by a terminal, an interference source HNB can be found easily, and an interference management of the interference source HNB also can be performed. The solution can avoid the situation in the prior art that the interference management is performed necessarily with a cell identity of the interference source HNB obtained by the terminal. With the application of the solution, the interference management to the HNB can be performed timely and effectively and the interference experienced by the terminal from the HNB is reduced.
