System and methods for multi-objective cell switch-off in wireless networks

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.

In order to more quickly detect a failure in a radio base station and complement the coverage thereof, a first base station included in a communication system forms a first cell to conduct radio communication with one or more mobile stations. A second base station, which is placed adjacent to the first base station, forms a second cell to conduct radio communication with one or more mobile stations. The first base station conducts communication with the second base station to monitor whether or not a failure occurs in the second base station. When it is detected as a result of the monitoring that the failure occurs in the second base station, the first base station expands coverage of the first cell so as to complement that of the second cell.
