Abstract

The invention relates to the technical field of space-air-ground-sea integrated communication, in particular to a multi-beam low-orbit satellite intelligent dynamic channel resource allocation method.The method comprises: using a low-orbit satellite as an Agent; mapping the number of beam service request users at the current service request moment and the initial state of channel occupation by beams into an environment; at each service request moment, sending a service request, according to the environment where the low-orbit satellite is located, using a Q-learning algorithm to observe an environment state and acquire an award signal of the environment; learning a state-action value function, changing the channel resource allocation strategy step by step, to complete dynamic channel resource allocation of the low-orbit satellite mobile communication system. It can be avoided that the same channel resource is allocated to users or beams within the multiplexing distance, and a channelresource allocation scheme capable of enabling the overall performance of the low-orbit satellite mobile communication system to be optimal is achieved.

Description

technical field [0001] The invention relates to the technical field of air-space-ground-sea integrated communication, in particular to a multi-beam low-orbit satellite intelligent dynamic channel resource allocation method. Background technique [0002] The air-space-ground-sea integrated information network is based on the ground network and expanded by the space-based network. It adopts a unified technical architecture, a unified technical system, and a unified standard specification. It is formed by the interconnection of the space-based information network, the Internet and the mobile communication network It has the characteristics of diversified service bearing, heterogeneous network interconnection, and global resource management. As an important national information infrastructure, the air-space-ground-sea integrated information network has great strategic significance for many fields such as homeland security, emergency relief, transportation, and economic developme...
