It is described a method (700) for reducing power consumption in a telecommunication system, the method (700) comprising: collecting (704) system data from at least a part of a plurality of subsystems (518) of the telecommunication system; determining a set of system constraints corresponding to the collected system data for at least the part of the plurality of subsystems (518); determining a configuration for at least the part of the plurality of subsystems (518) based on the collected system data so that a total power consumption for at least the part of the plurality of subsystems (518) is reduced and the determined set of system constraints is met; and applying (712) the determined configuration to at least the part of the plurality of subsystems to enforce the determined configuration.
