COMMUNICATION METHOD, APPARATUS, AND SYSTEM

Abstract: a communication method, apparatus, and system. the method may include: a terminal device receives satellite coverage information from a network device, where the satellite coverage information indicates time during which the terminal device is located in a coverage area of a satellite. when a coverage status of the terminal device indicated by the satellite coverage information does not match an actual satellite coverage status of the terminal device, the terminal device sends a registration request message to the network device. according to the foregoing solution, when the coverage status of the terminal device changes, the network device is enabled to update the satellite coverage information in time, so that reachability of the terminal device is not affected when the terminal device is located in the coverage area of the satellite.
