摘要： 随着通信技术的快速发展,卫星通信技术在当今信息通信领域扮演着至关重要的角色。卫星网络覆盖范围广,能够随时为全球用户提供低延迟服务。但卫星网络建设仍然面临卫星设计成本高、发射风险大、卫星网络的测试和维护成本昂贵等难题。随着数字孪生(Digital Twin,DT)技术的兴起,DT技术与卫星网络形成了一种完美的契合,为卫星网络运营提供了强大的数据支持和决策依据。文章综述了基于DT的卫星网络移动边缘计算的研究进展。首先介绍了地面基站通信的局限性,进而引出卫星网络的应用;其次详细阐述了卫星网络的组成结构、卫星分类及卫星边缘计算的概念;接着介绍了DT技术,并重点分析了DT卫星边缘计算平台和基于DT的卫星网络移动边缘计算算法;最后总结了当前研究中存在的问题和未来的发展方向。

Abstract: With the rapid development of communication technology,satellite communication has become a crucial part of modern information and communication landscape.Satellite networks,with their extensive coverage,can provide ubiquitous low-latency services to users worldwide.However,the construction of satellite networks still faces significant challenges,such as high satellite design costs,the risks associated with launches,and the expensive testing and maintenance of satellite networks.The rise ofdigi-tal twin(DT) technology presents a perfect synergy with satellite networks,offering powerful data support and decision-making tools for satellite network operations.This paper reviews the research progress on DT-based mobile edge computing in satellite networks.It begins by introducing the limitations of terrestrial base station communications,which leads to the discussion of satellite network applications.Then,the composition of satellite networks,satellite classifications,and the concept of satellite edge computing are thoroughly explained.Subsequently,DT technology is introduced,with a focus on the DT-based satellite edge computing platform and DT-based mobile edge computing algorithms for satellite networks.Finally,this paper summarizes the exis-ting issues in current research and outlines future development directions.

Key words: Satellite network, Satellite communication technology, Mobile edge computing, Digital twin
