Inter-satellite routing method for communication satellites, communication satellites and control device

Abstract

The invention discloses an inter-satellite routing method for communication satellites, the communication satellites and a control device, and the routing method comprises the steps: a first communication satellite determines a first spatial position where a core network is located, selects a second communication satellite according to the first spatial position, and uses the second communication satellite as a next routing node; and the communication data is directly or indirectly forwarded to the core network through the second communication satellite. The routing method further comprises a process opposite to the above steps. According to the invention, the next node of the route is determined according to the position of the core network, and the whole process does not need to exchange parameters among a plurality of communication satellites, thereby preventing the interaction process among the plurality of communication satellites from occupying the resources of the communication satellites, facilitating the improvement of the working efficiency of the communication satellites, facilitating the prevention of an overlong path, and reducing the time delay of data transmission. The method is widely applied to the technical field of satellite communication.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a communication satellite inter-satellite routing method, a communication satellite and a control device. Background technique [0002] At present, the technical concept of "6G=5G+satellite network" has emerged, that is, to realize 6G network through the combination of satellite mobile network and 5G mobile network. Let the mobile communication signal cover the air, ocean, forest, desert area and other sparsely populated areas to achieve truly global communication. However, the satellite mobile network also has a series of disadvantages, such as communication distance, power density, multi-antenna deployment, etc., which make the satellite mobile network communication more restricted, and the spectral efficiency of satellite communication is much lower than that of the cellular mobile communication system in the same period . Therefore, combining the ground mobi...

Problems solved by technology

In the prior art, it is usually necessary to exchange parameters between multiple communication satellites and execute routing algorithms to determine the communication path, which will occupy the resources of the communication satellites, reduce the work efficiency of the communication satellites, and also easily lead to unnecessary overtime. Long paths or the introduction of high-orbit satellites in the inter-satellite routing of low-orbit satellites, etc., thereby increasing the delay of data transmission
