Abstract: Embodiments are provided for a multi-objective scheme for solving a cell switch-off problem. The multi-objective solution seeks to minimize or reduce network energy consumption by switching off some of the cells in the network while allowing enough capacity according to traffic needs and quality of service requirement. An embodiment method includes determining, for each one of a plurality of established traffic profiles, a set of solutions with respect to a number of active cells from a plurality of cells in the network and an aggregate network capacity. The method further includes matching a given traffic profile to one of the established traffic profiles, and evaluating performances of the solutions corresponding to that traffic profile. A solution from the solutions is then selected in accordance with the evaluation. The selected solution indicates which of the cells in the wireless network to be switched off.
