Low earth orbit satellite network fault processing method and system, controller and medium

Abstract

The invention relates to a low-earth-orbit satellite network fault processing method and system, a controller and a medium, and the method comprises the steps: enabling low-earth-orbit satellites to be connected through physical links, and building a physical topological structure of a low-earth-orbit satellite network; establishing a logic topological structure of a control channel based on the physical topological structure, wherein the logic topological structure can traverse all low-earth-orbit satellites, and has no logic loop; monitoring whether a port, connected with an upstream low-earth-orbit satellite, of each low-earth-orbit satellite in the logic topological structure is closed or not; and if the port is closed, trying to establish communication connection with the low-earth-orbit satellites adjacent to the low-earth-orbit satellite one by one in each preset direction according to a preset sequence, and ending fault processing when connection succeeds or trying to connect in all preset directions is completed. According to the invention, the fault of the low-earth-orbit satellite network can be quickly found and repaired, the robustness of the whole low-earth-orbit satellite network is improved, the service support capability is improved, and the management and control cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of low-orbit satellite communication, in particular to a low-orbit satellite network fault processing method, system, controller and medium. Background technique [0002] The low-orbit satellite network refers to a space network composed of several 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] 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 multiple low-orbit satellites. Ea...

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
