Patent ID: 8515492

Claim:
Method for adapting a service provided by a base station in a cellular communication network to mobile stations in a coverage area of the base station, the method comprising: supplying the base station with energy from a renewable energy generator and/or from a back-up battery supply that is at least partially being charged by the renewable energy generator, and adapting the service in terms of coverage and/or a number of channels provided to the mobile stations as a function of an amount of stored energy in the back-up battery supply and/or as a function of a forecast regarding an amount of energy supplied by the renewable energy generator over a time period, wherein a capacity of the base station is defined as the number of channels and/or a bandwidth provided to the mobile stations, wherein there are a plurality of defined typical energy consumption patterns each corresponding to a coverage level and/or a capacity level provided by the base station, wherein the coverage and/or the capacity is adapted according to a determined defined typical energy consumption pattern among the plurality of defined typical energy consumption patterns, wherein the plurality of defined typical energy consumption patterns are prioritised according to minimized impact on user experience and include a first defined typical energy consumption pattern having a highest priority among the plurality of defined typical energy consumption patterns, and wherein the first defined typical energy consumption pattern is determined as the determined defined typical energy consumption pattern for situations in which the amount of stored energy in the back-up battery supply plus an amount of energy expected to be charged to the back-up battery supply over the time period assuming no energy consumption of the base station minus the expected energy consumption of the base station over the time period according to the typical energy consumption pattern is higher than a threshold value.
