Wireless resource scheduling method and architecture system based on low-orbit constellation satellite communication

Abstract

The invention provides a wireless resource scheduling method and architecture system based on low-orbit constellation satellite communication, and the method comprises the steps: dividing the wirelessresource scheduling of a low-orbit constellation satellite communication system into three data processing architecture systems according to the factors affecting a business data access system, wherein the system comprises a first-stage wireless resource scheduling center, a second-stage satellite resource scheduling module and a third-stage user service scheduling module. The wireless resource scheduling center carries out satellite service area and resource planning according to global frequency spectrum, resources, services and other data, satellites carry out resource scheduling for terminal users according to planning data, and the user service scheduling module handles priority adaptation of different service data. Low-orbit constellation satellite communication system network access of multi-service data is realized. Resource scheduling is decoupled through a layered low-orbit constellation satellite communication system resource system architecture, and wireless resource scheduling of the low-orbit constellation satellite communication system is optimized through processing and analysis of related data.

Description

technical field [0001] The invention relates to a wireless resource scheduling method and framework system based on low-orbit constellation satellite communication, in particular to the field of wireless communication networks. Background technique [0002] The low-orbit constellation satellite communication system consists of tens to tens of thousands of low-orbit satellites at an altitude of 200-2000km. These satellites form a satellite constellation to provide high-speed communication and Internet for various users of ground-based, sea-based, space-based, and space-based Access and other services. [0003] As one of the core functions of the operation and control system in the wireless communication system, wireless resource scheduling is the key to the rational allocation and utilization of wireless communication system resources. In the prior art, radio resource scheduling method allocation is relatively fixed, resulting in inflexible resource allocation, so it is not ...

AI Technical Summary

Problems solved by technology

In the prior art, the allocation of wireless resource scheduling methods is relatively fixed, resulting in inflexible resource allocation, which makes it difficult to realize changes with changes in users and services

At the same time, low-orbit satellites are constantly moving relative to the ground, and their covered areas, users, and services are also constantly changing. The fixed resource allocation model cannot adapt to this movement and change of the low-orbit constellation satellite communication system.
