摘　　要：从2G到5G移动通信系统,协议栈架构变化主要从成本、性能的角度进行功能拆分和重组,较少考虑不同场景需求引入的变化。基于未来通感算智等新业务融合的趋势,需针对新业务新场景在架构层面做原生的设计,移动系统将从管道单一角色转变到综合业务一体化处理角色。系统梳理了5G-NR网络架构中的协议栈设计,回顾相关功能编排,分析其对未来新场景业务的限制约束等,并进一步解析和展望未来系统架构在组件化方面的发展和应用趋势。From 2 G to 5 G mobile communication system, the change of protocol stack architecture mainly considers the function splitting and reorganization from the perspective of cost and performance.And there are few changes introduced by requirements of different scenarios.Due to the integration networking of communication, sensing, computing, intelligence and trust, the future radio access network should consider the native design at the architectural level for new business scenarios.And the role of the future communication system will be upgraded from a pipeline to a business processing integrated mode.This paper systematically reviews the network element and protocol stack design in the 5 G-NR network architecture, reviews the 5 G-NR function orchestration, analyzes its restrictions on future services, and further looks forward to the development and application trends of the component based design in future architecture.

关 键 词：新业务场景 网络架构 协议栈 组件化设计
