Satellite network communication method and device and computer readable storage medium

Abstract

The embodiment of the invention provides a satellite network communication method, satellite network communication equipment and a computer readable storage medium. The method comprises the followingsteps: sending a first greeting message containing a satellite identifier to a ground forwarding station, Wherein the first greeting message is used for indicating the ground forwarding station to record the satellite identifier into a local forwarding satellite record table; Receiving a second greeting message which is returned by the ground forwarding station and contains a forwarding station identifier; Updating a local forwarding station record; Wherein the forwarding station records comprise satellite identifiers of satellites connected with the ground forwarding station and forwarding station identifiers of the ground forwarding station connected with the satellite identifiers in an orbit where the forwarding station records are located; Generating a first broadcast message containing the forwarding station identifier and the satellite identifier, and broadcasting the first broadcast message to a satellite in an orbit where the first broadcast message is located; Wherein the first broadcast message is used for indicating the satellite in the orbit to update the local forwarding station record. According to the embodiment of the invention, the routing protocol re-convergence problem caused by inter-rail link change can be avoided, and the network packet loss rate is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a satellite network communication method, device, and computer-readable storage medium. Background technique [0002] With the development of globalization, satellite networking has gradually become a popular research direction in the field of satellite communications in recent years. Satellite networks have the characteristics of large coverage and broad application prospects. Among them, the low-orbit satellite network has gradually become the mainstream constellation solution for satellite networking due to its small inter-satellite delay and low power attenuation. [0003] The current low-orbit satellite network is mainly realized by constructing intra-orbit and inter-orbit inter-satellite links. Because of the existence of inter-orbit links, the number of inter-satellite links is large, and a grid-like connected network can be formed. In...
