摘要：卫星通信系统在技术和市场层面遇到发展瓶颈，需要与地面蜂窝网络系统进行融合升级。系统分析了卫星通信系统和5G新空口（5G-NR）系统融合的架构设计，包括单跳卫星融合架构、多跳卫星融合架构和卫星本地分流融合架构。认为未来卫星通信的无线电信号都将采取5G-NR规范方式，同时卫星通信系统在架构和功能特征等方面也将逐渐向下一代无线接入网（NG-RAN）靠拢对齐和同步演进。

Abstract: The satellite communication system has encountered development bottlenecks in terms of techniques and markets, and needs to be integrated and upgraded with the terrestrial cellular network system. The architecture design for the integration of satellite communication system and 5G new radio (5G-NR) system is systematically analyzed, including single-hop satellite integration architecture, multi-hop satellite integration architecture, and satellite local shunt integration architecture. It is considered that the radio signals of satellite communication will adopt 5G-NR specifications in the future, and the satellite communication system will gradually move towards next-generation radio access network (NG-RAN) in terms of architecture and functional characteristics.
Keywords: satellite communication; 5G new radio; next-generation radio access network; architecture integration
