Abstract
This application provides a handover method and apparatus in satellite communications. The handover method in satellite communications in this application includes: obtaining, by a terminal device, ephemeris information of first satellite base stations, where the first satellite base stations are satellite base stations that cover the terminal device; determining, by the terminal device based on the ephemeris information, a destination satellite base station to which the terminal device needs to hand over; determining, by the terminal device based on the determined destination satellite base station, a first time at which the terminal device is to hand over to the destination satellite base station; and handing over, by the terminal device based on the determined first time, to a destination cell served by the destination satellite base station. This application reduces power consumption of the terminal device, saves air interface resources, and further avoids a signaling storm caused because a large quantity of terminal devices report measurement information at the same moment, thereby increasing a handover success rate.
