One of the key decisions facing mobile operators worldwide is whether to launch 5G services in nonstandalone or standalone (SA) mode. The key difference is that the former relies upon existing 4G LTE network assets, such as an LTE evolved packet core, while the latter requires the deployment of a 5G core. Besides enabling new features, such as network slicing, 5G SA provides the full range of 5G capabilities in both public and private network deployment. This choice is not simply a matter of the availability of technology but also of spectrum, and we focus on the latter in the first reports of this “Mobile Radio” column.

5G独立部署呈上升趋势[移动无线电]


全球移动运营商面临的关键决策之一是是否以非独立或独立（SA）模式推出5G服务。主要区别在于，前者依赖于现有的 4G LTE 网络资产，例如 LTE 演进分组核心网，而后者则需要部署 5G 核心网。除了支持网络切片等新功能外，5G SA 还在公共和专用网络部署中提供全方位的 5G 功能。这种选择不仅仅是技术可用性的问题，还涉及频谱的问题，我们在本“移动无线电”专栏的第一份报告中重点关注后者。
