Abstract

The present invention discloses a sky-base mobile communication wireless resource management system. The system comprises a ground control center, which assigns the wireless resource for each satellite according to the operation status of the satellite communication system, a plurality of gateway stations, which are connected with the ground control center to manage the wireless resource of the satellite in the area covered by the gateway signal and control the satellite to assign wireless resource, and a plurality of satellites, which manage and assign the wireless resource related to the satellite according to the control signal of the gateway station and the ground control center. The present invention simplifies the control function of the ground, decreases the ground control dependence of the satellite mobile communication system and improves the anti-ruin ability of the system. Different management strategies can be conveniently implemented in different regions, thus the flexibility of the system operating is improved.

Description

technical field [0001] The invention relates to a wireless resource management system for satellite communication, in particular to a wireless resource management system based on a space-based system (system with satellite as the core), belonging to the field of aerospace information. Background technique [0002] Space-based mobile communication system is a kind of wireless communication system based on satellite network, using various types of satellites in different orbits as network access nodes to realize mutual communication between mobile users or between mobile users and fixed users . The communication system has independent information acquisition, storage, processing and distribution capabilities on the satellite, and can be interconnected with land, sea, and space-based information systems to realize multiple and three-dimensional sharing of information and become a next-generation mobile communication (4G) and national information system. An important part of th...
