摘要
通过对现有5G技术标准的对比分析,推荐了满足增强移动宽带(eMBB)业务需求的5G NSA Option3和满足更多业务需求的5G SA Option2;然后,介绍了4G核心网改造支持5G NSA Option3的关键技术;最后,对比4G核心网,介绍了5G SA Option2的主要技术特点和组网关键技术,包括用户移动性管理、网络切片和用户面承载,并简要介绍了商用部署涉及的UDM和PCF/UDR建设方案、融合组网与独立组网、5G信令网和语音业务解决方案。
By comparing and analyzing existing 5G technical standards, 5G NSA Option 3 to meet the needs of enhanced mobile broadband (eMBB) services and 5G SA Option 2 to meet more service requirements are recommended. Then, the key techniques to support 5G SA Option 3 by transforming 4G core network are introduced. Finally, in comparison to 4G core network, the main technical features and key networking techniques of 5G SA Option 2 are expounded including user mobility management, network slicing and user plane bearing, and solution to commercial deployment related to UDM and PCF/UDR construction schemes, integrated and independent networking, 5G signaling network and voice service.
