Communication method, apparatus, and system based on satellite network

Abstract

The application provides a communication method, an apparatus, and a system that are used in a satellite network. A user terminal receives, on a management channel, a sounding signal sent by a management satellite. The management satellite manages one or more serving satellites. The user terminal sends a respiratory signal to the management satellite. The respiratory signal carries information about the user terminal. The information about the user terminal is used to determine information about a serving satellite that serves the user terminal. The management satellite or a ground station may uniformly schedule the serving satellite to serve the user terminal. When the serving satellite is switched, a negotiation between satellites may be omitted.
