Low-orbit satellite network troubleshooting method, system, controller and medium

Abstract

The present invention relates to a low-orbit satellite network fault processing method, system, controller and medium. The method includes connecting low-orbit satellites using physical links to establish a physical topology of the low-orbit satellite network; The topology establishes a logical topology of the control channel, the logical topology can traverse all low-orbit satellites, and there is no logical loop; monitor each of the low-orbit satellites in the logical topology and upstream low-orbit satellites Whether the port of the satellite connection is closed, if it is closed, try to establish a communication connection with the low-orbit satellite adjacent to the low-orbit satellite in each preset direction one by one according to the preset sequence, and the connection is successful or completed in all preset directions. When connected, end troubleshooting. The invention can quickly find and repair the faults of the low-orbit satellite network, increase the robustness of the entire low-orbit satellite network, improve the support capability of the business, and greatly reduce the management and control cost.

Description

technical field [0001] The present invention relates to the technical field of low-orbit satellite communications, in particular to a low-orbit satellite network fault processing method, system, controller and medium. Background technique [0002] A low-orbit satellite network refers to a space network composed of a number of low-earth orbit (Low Earth Orbit, LEO) low-orbit satellites. Low-orbit satellites use radio to cover areas on the earth, and users in this area can access low-orbit satellites to achieve various forms of communication. The low-orbit satellite network can provide high-bandwidth, low-latency and almost global coverage interconnection services, and is considered to be an important technical solution for the next generation of global mobile networks. [0003] The traditional low-orbit satellite network forms such as figure 1 As shown, usually a low-orbit satellite is equipped with a ground station. There is no direct physical connection in space between m...

AI Technical Summary

Problems solved by technology

The deployment of a large number of ground stations leads to a surge in costs, and when one of the low-orbit satellites fails, the ground station corresponding to the low-orbit satellite will not be able to obtain information, the control flexibility is poor, and the failure cannot be found in time, and the failure recovery time is long
