摘要

基于高轨多波束卫星通信网络，设计捷变波束机制下用户终端随机接入网络的流程以及具体的信令交互，提出捷变信令波束的调度策略及分配方案。该方案在保证所有用户终端都能接入网络的前提下，提高接入资源分配的灵活性，有效地提升卫星网络资源的利用率。由于用户接入卫星通信网络的请求属于突发类型，更适合通过随机竞争的方式接入网络，因此在通用随机竞争接入策略基础上，提出一种基于热力值的自适应随机竞争接入算法，基于网络侧预测的热力值，用户选择不同的随机接入策略进行接入。通过对该优化算法的仿真分析，证明该算法可以有效地在各种网络负载下降低接入冲突概率，达到用户可以快速接入网络的目的。

Abstract

On the basis of geosynchronous earth orbit multi-beam satellite communication systems

this paper designed the process of user random access to the network and specifi c signaling interaction under the agile beam mechanism

and proposed the scheduling strategy and allocation scheme of the agile signaling beam.This scheme increased the fl exibility of access resource allocation under the premised of ensured that all users could accessed the network

eff ectively improved the utilization rate of satellite network resources.The request of user access to the satellite communication network belongs to the burst type

it is more suitable to use the random competition access

so this paper based on the general random competition access strategy

proposed an adaptive random competition access algorithm based on the heat value

based on the heat value predicted by the network side

the user selects diff erent random access strategies for access.Through the simulation and analysis of the optimization algorithm

it is proved that the algorithm could eff ectively reduced the probability of access collision under various network loads

so as to achieved the purpose of users quickly accessing the network.
