COMMUNICATION METHOD, COMMUNICATION APPARATUS AND COMMUNICATION SYSTEM

This application provides a communication method, a communication apparatus, and a communication system. The method includes: determining sleep time information of a terminal device based on satellite coverage information of the terminal device, where the satellite coverage information indicates a time period in which the terminal device is covered by a satellite network and/or a time period in which the terminal device is not covered by the satellite network, and a sleep time period corresponding to the sleep time information includes the time period in which the terminal device is not covered by the satellite network; and sending the sleep time information to the terminal device. According to the solution, the sleep time information is determined based on the satellite coverage information of the terminal device, and the sleep time period corresponding to the sleep time information includes the time period in which the terminal device is not covered by the satellite network, to ensure that the terminal device can sleep as much as possible in the time period in which the terminal device is not covered by the satellite network, and avoid unnecessary network connection operations such as cell selection, to reduce power consumption of the terminal device.
