Abstract

Embodiments of the present invention provide a satellite link switching method and device. Wherein, the method includes: obtaining the time range allowed to be adjusted by each link in the system cycle; determining the time slot corresponding to each link according to each time slot included in the system cycle and the time range allowed to be adjusted by each link in the system cycle; The slot number of the time slot corresponding to each link is sent to the satellites on each link so that each link performs link switching at the beginning of the corresponding time slot. The satellite link switching method and device provided by the embodiments of the present invention can adjust the asynchronous satellite link switching to the start time of the same time slot, so that the link switching in the time slot can be within the time of one slot Completing the handover can reduce the unreliable time of the network, improve the availability of the network, and reduce the overhead required for routing updates.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a satellite link switching method and device. Background technique [0002] In recent years, the maturity of satellite communication technology has accelerated the development of satellite networks, and the integration of satellite networks and ground networks to form an integrated network has gradually become the main trend of future network evolution. Unlike traditional terrestrial networks, an obvious feature of satellite networks is the highly dynamic topology, which has a huge impact on routing. [0003] At present, the application of IP technology to promote the integration of satellite networks and terrestrial networks has gradually become a consensus in the industry. In a satellite network, as the satellite moves around the earth, the link will be constantly disconnected and reconnected, that is, link switching. In a traditional satellite network...
