An algorithm which considers the individual power consumption profiles for different types of base stations in a heterogeneous cellular network, and determines which base stations can be switched OFF in line with the traffic demand. The algorithm predicts (302) a spatially-accurate network load; calculates (304) the best serving BS for each load region; investigates (308-318) toads on Pico cells with respect to a threshold, and ranks (320) candidate Pico cells to be switched OFF in order of least power efficiency and most resource efficiency. Pico cells determined to remain on are fully loaded (322) allowing more candidates to be switched OFF (324). The algorithm optimizes the energy efficiency of the heterogeneous, cellular network, enabling the activation of the minimum number of base stations to support the predicted traffic demand for a given time period and allowing significant energy savings for the operator.
