2020年6月2日 · Option 3x is the initial deployment option that helps mobile operators to start their 5G roadmap and accelerate their time to market for new 5G services. In this scenario service providers can leverage their existing EPC deployment and take on an incremental approach towards their 5G Capex and Opex.

2020年4月30日 · NSA Option 3x接入过程可以大致分为3个过程： 1） X2连接建立流程. 2） UE LTE接入流程. 3） SgNB添加流程. 下面分别进行介绍： X2连接建立流程： （1）SgNB触发X2建立连接：SgNB向MeNB发送X2 Setup Request消息，请求建立X2连接，MeNB接收到该消息回复X2 Setup Response消息。 （2）MeNB触发X2建立连接：MeNB向SgNB发送X2 Setup Request 消息，请求建立X2连接，SgNB接收到该消息回复X2 Setup Response消息。 UE LTE接入流 …

Option 3x for NSA and Option 2 for SA has become an industry consensus. SA is the target architecture, but the NSA ecosystem leads the SA for 6 months. The NSA can quickly deploy 5G network to support eMBB services and can be software upgraded to SA in the future.

2021年1月14日 · Option 3/3a/3x. As the early deployment architecture of 5G, NSA focuses on the eMBB scenario, reusing the current EPC and LTE as the anchor, which enables the quick introduction of 5G NR. Most operators choose NSA as the early deployment of 5G.

2021年7月26日 · 5G网络中的两种核心模式分别为SA和NSA，以下对两种模式进行简单说明：NSA非独立组网，即Non-Standalone。 NSA是将 5G 接入网（NR，NewRadio）与现有的4G核心网（EPC，EvolvedPacketCore）结合在一起。

选项3x是一种先进的架构，它无需对原有的4G站点进行硬件改造即可使用，同时它也解决了4G站点和5G站点无法进行负荷均衡的问题。选项3x具有投资小，初期建网速度快等优点，因此目前大部分运营商在NSA网络上都选择了选项3x。 图2.7 子选项3x架构. 2.2.2 选项4系列

2019年1月14日 · In the early 5G stages of deployment, Option 3/3a/3x will be the likely choice for many operators. As this approach is tied to LTE, it is important not to disrupt the existing network.

5G NSA networking mode option 3 series is divided into option 3, 3a and 3x. This article illustrates the architecture of different options, and summarizes the advantages and disadvantages of NSA option 3.

2023年2月22日 · Non-Standalone (NSA) deployment options, such as options 3, 3a, 3x, 4, 4a, 7, 7a, and 7x, provide a more incremental approach to 5G deployment, as they retain the existing LTE and EPC infrastructure while adding 5G capabilities.

2023年12月7日 · 5G NSA (Non-Standalone) architecture Option 3x is one of the deployment options defined by the 3GPP (3rd Generation Partnership Project) for the integration of 5G (New Radio, NR) with existing LTE (Long-Term Evolution) networks. In Option 3x, the architecture allows for dual connectivity, enabling simultaneous connections to both LTE and
