Disclosed are methods and system for dynamically switching at least a base station in ON/OFF mode in a cellular network. The method comprises: determining traffic load information of BSs; exchanging the traffic load information between BSs; determining at least a preferred BS for one of a switched OFF mode and a switched ON mode. The system comprises: at least a coverage BS with a master controller; at least a capacity BS with a slave controller adapted to be in one of the switched ON mode and the switched OFF mode depending on network conditions and to satisfy cellular traffic loads, and at least a communication interface adapted to provide interface between at least the coverage BS and the capacity BS.
