Abstract

The invention relates to a spatial internet information service method. The method comprises the following steps of providing a spatial internet information service system, wherein the spatial internet information service system comprises a plurality of communication satellites with movable communication load, a ground data center and a plurality of ground user terminals, each ground user terminal comprises at least one ground position fixed data terminal, at least one communication terminal and at least one broadcasting terminal; allocating wireless signal channels and utilizing the wireless signal channels by adopting default setting by virtue of mobile communication load after the spatial internet information service system is powered on or reset; acquiring useful information for optimizing the allocation and application of the wireless signal channel by virtue of the mobile communication load; allocating the signal channels according to the acquired useful information by virtue of the mobile communication load, and acquiring a signal channel allocation result; utilizing the signal channels according to the signal channel allocation result by virtue of the mobile communication load.

Description

technical field [0001] The present invention relates to an information service system and method, in particular to a spatial Internet information service system and method based on time-space reference. Background technique [0002] The low-orbit satellite constellation is a dozen to dozens of small satellites operating in low orbits, divided into several orbits, each orbit has several satellites, and revolves around the earth on several orbital planes, and the two adjacent orbital planes have a longitude equal distance. As a mobile communication relay station, the low-orbit satellite mobile communication system is like installing a terrestrial cellular mobile communication system on a satellite, forming wireless cellular coverage on the ground, covering the entire earth's surface, and providing services such as telephone, data and multimedia. With the rapid development of the mobile Internet, the core application of the low-orbit satellite mobile communication system is ch...
