Abstract: A data processing method, a related device, and a system are provided. The method executed by a first network device includes receiving PDH frame data; loading the PDH frame data and a stuffing bit into a virtual container to obtain the virtual container that includes the PDH frame data, where the stuffing bit in the virtual container carries information about a clock frequency difference between a clock frequency of the Ethernet and a clock frequency of the PDH frame data; and performing virtual-container PWE3 encapsulation on the virtual container to obtain a virtual-container PWE3 packet. In at least some embodiments, difficulty in recovering the clock frequency of the PDH frame data when the PDH frame data is transmitted in the Ethernet is reduced, clock frequency jitters and drifts caused by the clock frequency recovery are reduced, and user experience is improved.

Abstract: This application provides an electronic device, a charging method, and a charging system for charging two batteries connected in series. The charging integrated circuit controls, based on a target voltage corresponding to each preset period, a charging mode for charging the two batteries. As a charging process is prolonged, the voltages of the two batteries gradually increase, and the target voltage obtained varies with each period. A turning point of switching from constant current charging to constant voltage charging is determined based on the target voltage, and the target voltage is related to the minimum voltage value of the two batteries in each preset period. The charging mode is adjusted based on the target voltage corresponding to each preset period instead of a fixed target voltage. This reduces a probability of battery overcharging and improves battery charging reliability.

Abstract: Example antenna positioning methods for a first base station and communication apparatus are described. One example method includes receiving a first reference signal received power (RSRP) value by a server from a first base station, where the first RSRP value is measured by the first base station and is of a reference signal from a first neighboring base station of the first base station. The server determines an antenna azimuth of the first base station based on an RSRP set corresponding to the first neighboring base station and the first RSRP value, where the RSRP set corresponding to the first neighboring base station includes N RSRP values, and the N RSRP values correspond to N antenna azimuths of the first base station.
