网络切片已被确定为快速发展的5G技术的骨干。然而，随着其整合和标准化的进展，没有文献全面讨论其关键原则，使能因素和研究挑战。本文从端到端的角度阐述了网络切片，详细介绍了其历史遗产，主要概念，使能技术和解决方案以及当前的标准化工作。特别是，它概述了网络切片的各种用例和网络要求，预切片时代，考虑RAN共享以及端到端的编排和管理，包括无线电接入，传输网络和核心网络。本文还提供了5G系统每个部分的具体切片解决方案的细节。最后，本文确定了一些开放的研究挑战，并提供了潜在的解决方案的建议。
Network slicing has been identified as the backbone of the rapidly evolving 5G technology. However, as its consolidation and standardization progress, there are no literatures that comprehensively discuss its key principles, enablers, and research challenges. This paper elaborates network slicing from an end-to-end perspective detailing its historical heritage, principal concepts, enabling technologies and solutions as well as the current standardization efforts. In particular, it overviews the diverse use cases and network requirements of network slicing, the pre-slicing era, considering RAN sharing as well as the end-to-end orchestration and management, encompassing the radio access, transport network and the core network. This paper also provides details of specific slicing solutions for each part of the 5G system. Finally, this paper identifies a number of open research challenges and provides recommendations toward potential solutions.
