Problems solved by technology

Because low-orbit satellites move very fast, usually higher than 7km / s, and low-orbit satellite constellations have a highly dynamic topology, the visibility time for ground terminals is usually only 10 minutes, requiring frequent switching, which is likely to cause call blocking, Communication quality declines, frequent switching wastes resources and other issues, which makes the mobile switching management strategy a key problem that needs to be solved urgently in the satellite Internet system

Abstract

The invention provides a mobile switching method and system for a low-orbit communication satellite constellation, and the method specifically comprises the steps: firstly, entering a switching process when the quality of a currently connected satellite link is lower than a threshold value, and sequentially selecting the satellite links according to the quality of the satellite links; secondly, judging whether the on-board capacity load can meet user communication requirements or not; and finally, judging whether the remaining visible time of the satellite meets the threshold requirement or not, and avoiding the problem of frequent ping-pong switching. The method is flexible and reliable, engineering implementation is simple, the success rate of switching of the terminal between beams and satellites is effectively improved, the switching frequency is reduced, and the user communication quality and the service experience can be improved.

Description

Technical field[0001]The present invention relates to the field of satellite communications, and more particularly to a mobile switching method and system for low rail communication satellite constellation.Background technique[0002]Since the low-track satellite constellation has a wide range of coverage, delay, low power consumption, and high destruction, the satellite Internet system consisting of low rail communication satellite is an important part of the integrated mobile communication network in the future.[0003]Such asfigure 1 As shown, in order to ensure the quality of service, the low rail communication satellite constellation usually forms multiple coverage on the ground, so the ground terminal may enter multiple low-track satellite coverage. Since the low-track satellite movement is very fast, it is usually higher than 7km / s, and the low-track satellite constellation has a high dynamic topology. For the ground terminal, the visual time is usually only 10 minutes, and it ...
