Abstract: This application discloses a network device and a method. The network device includes a plurality of power supply units, a plurality of radio frequency units, and a control unit. Each of the plurality of radio frequency units is connected to at least one of the plurality of power supply units. The control unit is connected to both the plurality of power supply units and the plurality of radio frequency units. The control unit is configured to: control a load on a first carrier to change in a first manner; obtain power consumption of the plurality of power supply units when the load on the first carrier changes; and determine, from the plurality of power supply units based on the power consumption of the plurality of power supply units, a first target power supply unit that supplies power to the radio frequency unit corresponding to the first carrier.

Abstract: 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 (101) 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 (101) 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 (101) may be adjusted, to reduce the average power consumption of the communication station (101) within the time period corresponding to the target power supplying duration.
