1. A backup power supply control method comprising:
obtaining a target power supplying duration of a battery, and determining an 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, an actual power supplying duration for the battery to supply a power to the communication station; and
in response to the actual power supplying duration being 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, such that the actual power supplying duration for the battery to supply the power to the communication station is enabled to be greater than or equal to the target power supplying duration,
wherein the determining the average power consumption of the communication station within the 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 a current power consumption of the communication station;
determining a total power consumption of the communication station within a first historical time period based on the historical power consumption data, wherein a start point of time of the first historical time period is a first historical point of time, and the first historical time period has a duration equal to the target power supplying duration; and
determining the average power consumption based on the total power consumption and a relationship between a first power consumption and the current power consumption.
