有反馈5G NSA终端回落到4G后无法再自动返回5G的问题，我这边测试研究了下，做个总结。
这篇文章：
5G NSA组网SCG添加流程
https://www.txrjy.com/thread-1111072-1-1.html
对于工作在NSA模式的终端（UE），是如何实现EN-DC，添加上5G这条大腿呢？
大致可以分为如下几个步骤：
**一、终端注册到LTE网络锚点频率。**与过去4G网络信令流程相比没有大的变化：终端读取LTE系统消息，发起随机接入，附着到LTE网络。这一步中，LTE的SIB2消息中会携带一个字段，叫做"Upper Layer Indication r15"用于指示当前是不是有5G网络，但也仅仅是指示，实际上是否有5G网络并不确定，所以才会有"真假5G"的争执。同时，如果UE支持NSA，会在上报5G能力给网络，通过UE Capability的UE MR-DC Capability来指示。
二、**终端测量NR频点信息并上报测量结果。**上一步中，UE上报给网络支持NSA后，LTE网络将下发B1测量，将需要终端测量的NR频率信息通过RRC重配消息发给终端。终端收到后获取NR同步信号并测量5G信号质量，将测量结果上报LTE网络。
三、LTE网络根据测量结果决定是否添加SCG。
这里涉及到SCG的添加条件，一般有两个条件（1）5G信号质量还不错，高于一个门限值，比如-110dBm；（2）UE现在的数据业务速率要求高，高于一定吞吐量，比如5Mbps。为了让用户尽可能的使用5G网络，目前运营商基本没有设置第二个条件。
也就是说，如果终端检测到的5G信号质量符合要求，LTE基站将与NR基站进行通信，为NR承载分配资源，并通过LTE RRC连接重配消息向终端发送NR资源分配信息。大致流程参见下图1-5。
还有介绍从终端到核心网的各种流程，有需要的可以参考。
本文仅从终端侧结合终端的log做相关介绍。
5G NSA添加辅小区的正常流程
1、网络SIB2消息中：upperLayerIndication-r15 true
upperLayerIndication-r15 用于指示当前是不是有5G网络。

}
}
upperLayerIndication的解释见：3GPP TS 36.331
NOTE: upperLayerIndication is an indication to upper layers that the UE has entered a coverage area that offers 5G capabilities.
2、终端支持ENDC双连接：

4、网络是否限制DCNR
正常在Attach accept Msg中没有restrict_dcnr字段，或该字段值为0。
如果网络限制终端DCNR的接入，在Attach accept Msg中会看到restrict_dcnr字段为1：

keyToUse介绍
---------------------------------------3GPP TS 38.331 ------------------------------------
keyToUse
Indicates if the bearers configured with the list in this radioBearerConfig is using the master key or the secondary key for deriving ciphering and/or integrity protection keys. For EN-DC, network should not configure SRB1 and SRB2 with secondary key and SRB3 with the master key. When the field is not included, the UE shall continue to use the currently configured keyToUse for the radio bearers reconfigured with the lists in this radioBearerConfig except for mobility from NR to E-UTRA/5GC. If EN-DC is not configured, this field is set to master.
---------------------------------------3GPP TS 38.331 ------------------------------------
SRB1，SRB2，SRB3的作用分别是什么？
SRB1、SRB2和SRB3是LTE系统中的三个专用承载（Dedicated Bearer），它们的作用如下：
-
SRB1（Signaling Radio Bearer 1）：用于传输控制平面（Control Plane）信令，如RRC连接建立、释放、重配置等信令。SRB1是一个必需的承载，它的优先级最高，且不可被释放。
-
SRB2（Signaling Radio Bearer 2）：用于传输NAS（Non-Access Stratum）信令，如Attach、Detach、Authentication等信令。SRB2是一个可选的承载，它的优先级次于SRB1，但高于所有的用户面承载（Bearer）。
-
SRB3（Signaling Radio Bearer 3）：用于传输RRC（Radio Resource Control）信令，如RRC Connection Reconfiguration等信令。SRB3是一个可选的承载，它的优先级次于SRB1和SRB2，但高于所有的用户面承载（Bearer）。
需要注意的是，SRB1、SRB2和SRB3的优先级是不同的，且它们的用途也不同。在EN-DC（E-UTRA-NR Dual Connectivity）场景下，SRB1和SRB2应该使用主密钥进行加密和完整性保护，而SRB3应该使用辅助密钥进行加密和完整性保护。
这时通知上层显示的技术变为5G了

小结
终端移动到信号差的地方，NSA掉了，Service Request再次发起时是注册在非锚点小区的，虽说后面后面移动了信号好的地方，也TAU到了锚点小区，但网络一直不配NR测量，直到RRCConnectionRelease后再次发起Service Request才再次添加了NSA辅小区。可见在一定条件下RRC连接态网络是不配置NR测量的，也就无法添加NSA辅小区了。
2、信号差导致不添加NSA辅小区
问题描述：19:39左右对比机和设备同时掉到4G，但对比机在20:08回到5G，设备始终无法回到5G，20:27手动重启设备后才能恢复5G
log分析：
通过日志可以看出终端一直在进行NR测量，但信号RSRP一直不好，有时信号可以但信号质量RSRQ不好，见如下log，这应该是回不到5G的原因。
对比机可以的话，可以对比看看是否注册在LTE相同的频段，5G信号测量是否有差异；

Inequality A2-1 (Entering condition)
Ms - Hys < Thresh
RRCConnectionReconfiguration中的A2事件，信号要低于(21+2)-140=-117dBm时才会启动异频/异系统测量，现在E-ARFCN = 1675的信号在80~90之间，优先级又最高，因此设备被固定在了E-ARFCN = 1675。

该频点上应该没有锚定小区，所以回不到5G NSA了
后面多次RRCConnectionRelease都是配置的carrierFreq 1675为最高优先级cellReselectionPriority 7，设备被固定到该频点上，该频点上应该没有锚定小区，所以回不到5G NSA了。
