摘要:

由于现有移动通信网络可能无法满足新兴技术和应用的低时延与高效能需求,需要研究新型网络架构来支持这些新需求。作为一种整合卫星系统、空中网络和地面通信的新型网络架构,空天地一体化网络(SAGIN)近年来引起了广泛关注。本文从多个方面总结了SAGIN的最新研究工作,首先介绍了SAGIN的基本信息,随后阐述了其物理特性。接着,深入分析了当前SAGIN架构在支持新需求方面的驱动力与前景。在此基础上,分析了各项需求与挑战。最后,总结了现有解决方案并展望了未来的研究方向。

英文摘要:

Since existing mobile communication networks may not be able to meet the low latency and high-efficiency requirements of emerging technologies and applications, novel network architectures need to be investigated to support these new requirements. As a new network architecture that integrates satellite systems, air networks and ground communication, Space-Air-Ground Integrated Network (SAGIN) has attracted extensive attention in recent years. This paper summarizes the recent research work on SAGIN from several aspects, with the basic information of SAGIN first introduced, followed by the physical characteristics. Then the drive and prospects of the current SAGIN architecture in supporting new requirements are deeply analyzed. On this basis, the requirements and challenges are analyzed. Finally, it summarizes the existing solutions and prospects the future research directions.
