It is very expensive for operators to deploy SA 5G directly, so upgrading to NSA with existing network architecture and then migrating to SA 5G is the most common scenario.The NSA can be upgraded based on the existing 4G base station, which not only saves costs, but can also be quickly d...
Understand the differences between NSA and standalone 5G deployments to meet strategic targets and ensure maximum ROI while delivering quality connectivity.
on devices that support fifth-gen network services. To smoothly transition from the existing legacy core to 5G, MNOs have two pathways: Non-Standalone (NSA) or Standalone (SA) architecture. And while they are both means to the same end, NSA and SA are structurally ...
5G 网络架构分成了 SA 和 NSA,R15 版本分成了两个阶段,第一个阶段发布的是 NSA,第二阶段发布的是SA,它们的部署是不相同的。SA 即是 Standalone独立组网,即一套全新的 5G 网络,包括全新的基站和核心网。NSA 为非独立组网,使用现有的 4G 网络,进行改造、升级和增加一些 5G 设备,使网络可以让用户体验到 5G ...
Route 1: LTE > 5G NSA > 5G SA Service providers deploying 5G non-standalone architecture as an intermediate step to full 5G standalone architecture. This has made it possible for service providers to switch on 5G services as quickly as possible, while using LTE as a fallback. ...
Enterprise communications engineers should keep in mind, though, that 5G SA cores are new code stacks implementing new protocols. On the one hand, that can mean leaving behind the bugs and fixes of older systems, and the inevitable outcome is a patchwork, such as 5G NSA, with risks to func...
5G的第一版规范(含NSA和SA):R15(2018年) 主打eMBB 5G的第二版规范(SA):R16(预计2020一季度) 主打MMTC和uRLLC以及网络的增强功能 5.5G核心网主要功能概述 5G核心网架构的主要功能概述 SBA的架构,4G以网元为中心->5G以功能、服务为中心 CUPS(控制与用户面的分离) ...

While comparing with NSA Option 3, SA Option 2 does not require tight coupling between eNB and gNB. SA Option 2 devices access 5GC with control signalling independent of 4G network and achieve interoperability between 4G and 5G networks through their core networks. 4G/5G inter working mainly in...
基于独立或与LTE协调的联合 RAT 操作，有两种主要模式，即非独立 （NSA） 和独立 （SA）组网 。在独...
