摘　　要：随着互联网从消费型网络向生产型网络升级,新兴行业应用需要差异化的确定性服务质量保障以及全时空范围的通信能力。如何实现泛在多域网络的异构兼容,支持空天地一体化网络(SAGIN)节点间的确定性传输成为当前的重要研究问题。首先分析了面向6G全域新兴应用场景的确定性服务质量保障需求,然后提出了包含全域协同网络管控层、多域动态确定性融合层、泛在异构确定性组网层的分层空天地一体化确定性网络架构,并研究相应场景的“固移卫”融合确定性网络关键技术,最后研判了空天地一体化确定性网络的挑战和发展趋势。As the Internet evolves from a consumer network to a productive network,emerging industry applications necessitate differentiated and deterministic service quality assurance and communication capabilities that span all dimensions of time and space.How to realize the heterogeneous compatibility of ubiquitous multi-domain networks and support deterministic transmission between nodes in space-air-ground integrated network(SAGIN)has become a significant research problem.Firstly,the emerging full-domain 6G scenarios along with their requirements for deterministic services were analyzed.Then,the hierarchical space-air-ground integrated deterministic networking architecture,including global cooperative network management and control layer,multi-domain dynamic deterministic fusion layer,and ubiquitous heterogeneous deterministic networking layer,was proposed,and key technologies for fixed-mobile-satellite fusion networks in relevant scenarios were studied.Finally,the challenges and development trend of the space-air-ground integrated deterministic networking were presented.
