摘要：

随着5G愿景和概念逐渐地清晰，业界越发意识到网络技术发展对5G系统的重要价值。5G网络旨在以高性能和高效能为目标重构全网架构和服务体系，支撑5G指标和场景，满足高效运营的要求。引入了“自顶向下”的设计方法，从5G场景与需求与网络挑战映射分析入手，梳理了5G 架构发展方向，描述5G 概要级网络架构和基础设施框架，并对不同功能平面的架构方案具体展开，提出5G网络核心功能——网络切片，在最后对5G网络标准化推进节奏进行了总结。提出的架构方案能匹配5G业务和运营需求，对5G网络后续研究工作具有推动作用。

关键词: 5G, 网络架构, 功能重构, 网络切片, 标准化

Abstract:

The industry has been more and more aware of the important value of network technologies to the 5G system since the vision and the concept of 5G has become clear and focused. Taking higher performance and efficiency as its objective，5G network is about to reconstruct the entire architecture and service provision system to meet the demands of 5G KPIs，scenarios and operations. A top-down design method was introduced which firstly identified the relationships between 5G requirements and technology challenge on legacy network and deduced the development direction of 5G architecture，then the 5G high-level framework of network architecture and infrastructure were raised and the architecture solution for each network function plane and the key network service named as network slicing were proposed in detail. Finally，the standardization progress in main SDOs was summarized. The solution raised can match the 5G service and operational requirements and give an active impetus to the subsequent 5G network research.

Key words: 5G, network architecture, function reconstruction, network slicing, standardization
