BACKUP POWER SUPPLY CONTROL METHOD, APPARATUS, AND SYSTEM

This application relate to the field of communications technologies, and disclose a backup power supply control method, to obtain target power supplying duration of a battery, and determine average power consumption of a communication station () within a time period corresponding to the target power supplying duration. Further, a state of charge of the battery is obtained, and actual power supplying duration for the battery to supply power to the communication station () is determined based on the state of charge of the battery and the average power consumption. Therefore, an operation mode of a communication device in the communication station () may be adjusted, to reduce the average power consumption of the communication station () within the time period corresponding to the target power supplying duration.
