摘要：

随着人类活动范围从大陆向海洋、太空的不断扩展，世界各国纷纷开始布局全球无缝覆盖、连接无处不在的天地一体化信息网络建设。天地一体化信息网络是天基网络与地面网络的深度融合，不是简单的地面向空间的拓展与叠加。从融合的角度出发，首先梳理了地面互联网、移动通信网、天基信息网络发展现状以及存在的问题与挑战；然后总结分析了天地一体化信息网络体系架构研究现状以及新型网络架构向云化、智能化发展的趋势；最后提出了通信、网络、计算融合的天地一体化信息网络的体系架构，并从物理架构、功能架构、物理与功能架构映射等多个维度进行了阐述，提出了一体化信息通信系统、一体化网络系统、一体化信息系统的3层功能架构模型，以期为后续天地一体化信息网络的研究、建设和标准化提供有价值的建议和参考。

Abstract:

With the continuous expansion of human activities from the terrestrial to the ocean and space, the countries all over the world have advanced the layout of space-ground integrated information network to provide seamless coverage and ubiquitous connection services.Space-ground integrated information network is the deep integration of space network and terrestrial network, not the expansion of terrestrial network to space environment.Starting from the perspective of integration, firstly the development status, existing problems and challenges of the internet, public land mobile network (PLMN), and space networks were sorted out.Secondly, the research status of the space-ground integrated information network architecture and the development trend of the new network architecture such as cloudification and intelligence was summarized.Thirdly, a communication-networking-computing integrated space-ground integrated information network architecture was proposed from different dimensions: physical architecture, functional architecture (including the integrated communication system, the integrated network system and the integrated information system), physical-functional architecture mapping problem.Finally, the network architecture optimization problem was modeled as a multi-objective optimization problem.It was expected to provide valuable suggestions and references for the research, construction and standardization of space-ground integrated information network.

Key words: space-ground integrated information network, space network, internet, mobile network, network architecture
