Problems solved by technology

However, this type of method is to go around after a problem occurs. For example, when congestion occurs here, the congestion avoidance mechanism is selected to go around, and it does not pay attention to the service of the corresponding inter-satellite link to a specific satellite in the time slice when the problem occurs. The update of the score leads to the calculation of a new routing path to bypass the problematic inter-satellite link every time the same problem occurs in the time slice. Therefore, there is an urgent need for a method that can The inter-satellite link reconstructs the routing path based on the service score of a specific satellite, so that the setting of the routing path of the satellite communication network can be gradually optimized according to the service score, and the routing efficiency is improved.

Abstract

The invention relates to an optimal reconstruction method and system of a satellite communication route path. The method comprises the following steps: an indication of a problem influencing the specific inter-satellite link between a second satellite and a third satellite is received at a first satellite, wherein the first satellite associatively sends the indication and specifically located first time slice in the receiving of the indication to an earth station so as to request the earth station to update service score on the first satellite by the inter-satellite link between the second satellite and the third satellite at the first time slice; the earth station notifies the first satellite to delete the connection of the second satellite and the third satellite in a corresponding topological structure if the updated service score is less than a preset score threshold; and the first satellite updates route information in response to the deleting notification, and reconstructs at least partial rout path of the first time slice according to the updated route information. The route path can be reconstructed according to the service score on a specified satellite by the corresponding inter-satellite link in the corresponding time slice, so that the setting of the route path can be progressively optimized.

Description

technical field [0001] The invention relates to the technical field of telecommunications, in particular to a method and system for optimizing and reconfiguring satellite communication routing paths. Background technique [0002] The satellite communication network has developed from a small network composed of a few satellites to a large constellation composed of dozens or even hundreds of satellites. For the ever-expanding satellite network, more and more information needs to be collected and calculated, and the corresponding processing capacity requirements are getting higher and higher. However, the processing capacity of the satellite router is limited, and it cannot be upgraded and updated at any time like the ground router. In addition, collecting status information of the entire satellite network will also increase the burden on the inter-satellite link. If the traditional method is used to only calculate the on-board routing table by the satellite, it is difficult ...
