Satellite coverage area division method, satellite coverage area switching method and related equipment

Abstract

The invention provides a satellite coverage area division method, a satellite coverage area switching method and related equipment, and the method comprises the steps: obtaining the movement direction configuration information of a satellite, and taking the movement direction represented by the movement direction configuration information of the satellite as a target direction; a beam coverage area of a satellite is divided in a division mode that a coverage range of a cell in a target direction is greater than a set range threshold value to obtain a plurality of cells, so that the divided cells can have a larger range in the target direction and meet the requirement of reducing terminal switching times, and on the basis, when the satellite moves according to the target direction, the user experience is improved. According to the embodiment of the invention, the residence time of the terminal in each cell can be prolonged, so that the terminal can report the measurement result within enough time, the accuracy of the measurement result obtained by the satellite base station is ensured, and the cell switching based on measurement is supported. Moreover, after the terminal prolongs the residence time of the terminal in each cell, the switching frequency can be reduced, and the signaling overhead of the air interface due to frequent measurement and switching configuration is reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method for dividing a coverage area of ​​a satellite, a method for handover, and related equipment. Background technique [0002] At present, the existing communication protocols (4G\5G) can be relayed through satellites to achieve global coverage of wireless Internet. The types of satellites used include both synchronous satellites and low-earth orbit satellites such as low-orbit satellites. [0003] Since the coverage area of ​​the satellite on the ground is relatively large, such a large coverage area is not suitable for providing services to terrestrial users through only one logical cell. Therefore, it needs to be divided into finer cells. Among them, the low-earth orbit satellites are in a high-speed flight state relative to the ground. The coverage area of ​​a satellite is divided into more cells, which leads to the terminal staying in each cell f...

AI Technical Summary

Problems solved by technology

Among them, the low-Earth orbit satellites are flying at high speed relative to the ground. The coverage area of ​​a satellite is divided into more cells, which leads to the short stay time of the terminal in each cell, which leads to frequent cell switching of the terminal.

Among them, the terminal cannot stay in each cell for a long time, so that the terminal does not have enough time to report the measurement results, making it difficult for the satellite base station to obtain accurate measurement results, and it is impossible to perform cell handover based on the measurement

[0004] In addition, the frequent handover of the cell of the terminal will lead to a large signaling overhead due to frequent measurement and handover configuration of the air interface
