Abstract

The present invention discloses an MIMO satellite service system and a method for providing an MIMO satellite service. According to the present invention, by periodically reporting terminal status information to a gateway platform, and acquiring connectable satellite communication systems of all MIMO satellite service terminals from a broadcast message, all MIMO satellite service terminals that access a network can update, in real time, types of satellite communication systems that can be connected by other terminals in the network. Therefore, not only a same satellite communication system can be selected to perform communication, but also communication across satellite communication systems can be performed based on forwarding of the gateway platform. Therefore, flexibility of satellite communication is improved, and interconnection and intercommunication are implemented for users that use different satellite communication systems, thereby improving application convenience of users that access a network, and also improving a bandwidth utilization rate of a communication system.
