A backup power supply control method, wherein the method comprises: obtaining target power supplying duration of a battery, and determining average power consumption of a communication station within a time period corresponding to the target power supplying duration; obtaining a state of charge of the battery, and determining, based on the state of charge of the battery and the average power consumption, actual power supplying duration for the battery to supply power to the communication station; and if the actual power supplying duration is less than the target power supplying duration, adjusting an operation mode of a communication device in the communication station, to reduce the average power consumption, wherein actual power supplying duration for the battery to supply power to the communication station whose average power consumption is reduced is enabled to be greater than or equal to the target power supplying duration; and wherein the determining average power consumption of a communication station within a time period corresponding to the target power supplying duration comprises: obtaining historical power consumption data of the communication station within a first preset historical time period, and obtaining current power consumption of the communication station; matching the current power consumption of the communication station with the historical power consumption data, and determining, in the historical power consumption data, first power consumption corresponding to the current power consumption, wherein the first power consumption is power consumption corresponding to the communication station at a first historical moment within the first preset historical time period; determining total power consumption of the communication station within a first historical time period based on the historical power consumption data, wherein a start moment of the first historical time period is the first historical moment, and the first historical time period has duration equal to the target power supplying duration; and determining the average power consumption based on the total power consumption and a relationship between the first power consumption and the current power consumption. obtaining target power supplying duration of a battery, and determining average power consumption of a communication station within a time period corresponding to the target power supplying duration;
