Problems solved by technology

However, due to the high-speed movement of the low-orbit satellite system, there will be frequent switching. If a suitable link cannot be switched, the communication will be interrupted or the communication delay will be greatly increased.
[0003] Most of the current paging is coarse-grained paging, that is, a large number of satellites will be paged to connect to idle satellite terminals, which will bring a lot of signaling overhead and put great pressure on satellite communications , so that the communication efficiency is not high

Abstract

The invention discloses a paging method, system, device and storage medium for a low-orbit satellite based on a 5G core network; the method includes calculating the real-time position of the satellite terminal according to the historical position of the satellite terminal; Calculate the real-time position of the satellite based on the almanac data; calculate the satellite list according to the real-time position of the satellite terminal and the real-time position of the satellite; obtain the spot beam list corresponding to each satellite in the satellite list; use the prediction model to calculate each point in the spot beam list The busy probability of the beam; the spot beam with the smallest busy probability is selected for paging. The present invention does not need to blindly send information to batches of satellites to achieve the purpose of paging satellite terminals, can reduce signaling consumption and paging time delay, and improve communication efficiency. The invention can be widely used in the technical field of satellite mobile communication.

Description

technical field [0001] The present invention relates to the technical field of satellite mobile communication, in particular to a paging method, system, device and storage medium for a low-orbit satellite based on a 5G core network. Background technique [0002] With the rapid development of satellite communication systems, problems such as call quality, data transmission rate and use cost that restricted the early low-orbit satellite communication systems have been solved, and the application time of low-orbit satellite communication has matured. Orbit and spectrum are very important conditions for the normal operation of communication satellites. The combination of 5G and low-orbit satellites can bring high-quality communications with global coverage. However, due to the high-speed movement of the low-orbit satellite system, there will be frequent switching. If a suitable link cannot be switched, the communication will be interrupted or the communication delay will be grea...
