摘要: 临空信息网络具有高时效部署和能实现广域通信覆盖与局部能力增强的优势,能助力提升我国开展公共安全应急响应与救灾、对地观测等重大任务的能力。与地面无线网络和天基网络相比,临空信息网络信道传播特性新,拓扑立体多层,平台多异质且共享空域,导致地面无线网络和天基网络的信道建模与动态部署方法不适用于临空信息网络。为发挥临空信息网络的优势,亟需攻关临空信息网络信道建模与动态部署关键技术。剖析了临空信息网络在信道建模与动态部署研究方面面临的重大挑战,并展望了应对挑战的关键技术。此外,在最后展望了临空信息网络未来的其他重点研究方向。

Abstract: The near space information network has the advantages of high time-effective deployment, wide-area communication coverage and local capacity enhancement, and can help enhance the ability of China to carry out major tasks such as public safety emergency response and disaster relief, and earth observation. The near space information network has novel channel propagation characteristics, a three-dimensional and multi-layer topology, and multi-heterogeneous and airspace-shared platforms, which make the channel modeling and dynamic deployment approaches of terrestrial wireless networks and space-based networks inapplicable to the near space information network. To take advantage of the near space information network, it is urgent to tackle the key technologies of channel modeling and dynamic deployment of the near space information network. This paper analyzes the major challenges in channel modeling and dynamic deployment for the near space information network, and discusses the key technologies to address the challenges. Some key research directions of the near space information network in the near future are also discussed.

Key words: near space information network, wide-area coverage, local enhancement, channel modeling, dynamic deployment
