摘　　要：为了满足巨流量、大链接、超低时延等5G组网性能需求,针对广覆盖和高容量设计的传统无线接入网络架构亟需演进。首先结合5G愿景与需求,阐明了5G接入网络架构的特点和重要性;然后从学术界和产业界两个角度详细介绍了5G接入网络架构的设计原理和具体组成,分析了优点和不足;最后,探讨了接入网络架构的挑战和未来的可能发展方向。In order to meet the performance requirements of 5 G networking such as huge traffic, large links, and ultra-low latency, the traditional wireless access network architecture for wide coverage and high capacity design needs to evolve. Firstly, combining the 5 G vision and needs, the characteristics and importance of the 5 G access network architecture were clarified. Then the design principle and specific composition of the 5 G access network architecture was introduced from the perspectives of academia and industry, and the advantages and disadvantages were analyzed. Finally, the challenges of access network architecture and possible future development directions were discussed.
