摘要
全面构建空天地海一体化网络成为6G的重要发展方向,然而,空天地海一体化网络的通信拓扑高动态变化、网络体系结构复杂以及多维资源分布非均衡等特点,给网络切片带来了挑战。介绍了空天地海一体化网络和网络切片技术的研究进展;然后分析了空天地海一体化网络中网络切片目前面临的多维资源分布高度不均衡、物理拓扑和业务需求的双重高动态性挑战;最后讨论了切片间资源重用和智能自适应切片伸缩这两个未来的发展趋势。
The comprehensive construction of a space-air-ground-sea integrated network has become an important development direction for the sixth-generation(6G)wireless communications.However,the highly dynamic change of communication topology,complex network architecture and the unbalanced distribution of multidimensional resources in the space-air-ground-sea integrated network bring challenges to network slicing.The research progresses of the space-air-ground-sea integrated network as well as network slicing technology are introduced.Then the current challenges faced by network slicing for the space-air-ground-sea integrated network are analyzed from the perspectives of highly uneven distribution of multi-dimensional resources and the dual high dynamics of physical topology and service requirements.Finally,the future development trends are discussed in terms of inter-slice resource reuse and intelligent adaptive slice scaling.
