The embodiments of the application relate to the technical field of wireless communications, especially relate to a method, system and device for cell management, which are used to manage the cells under the local node in the hierarchical network deployments scene of segregation of user plane and control plane. The method of the embodiments of the application includes: a macro base station determines the need to manage the cells under a local base station; the macro base station notifies said local base station to manage the cells under the local base station. In the embodiments of the application the macro base station notifies the local base station to manage the cells under the local base station. Since in the embodiments of application the macro base station assists the local base station to manage the cells under the local base station, thus implementing to manage the cells under the local node in the hierarchical network deployment scene of segregation of user plane and control plane, further improving the system performance.
