看LOG学5G(63)-NSA锚点小区下发的切换命令

看LOG学5G(63)--NSA锚点小区下发的切换命令在NSA网络中终端按照服务小区的测量配置对4G小区和5G小区进行测量；根据测量报告配置上报4G和5G服务小区和邻区的测量报告;请参看:看LOG学5G(62)--NSA中终端上报的测量报告)

图1.支持双连接UE上报的测量报告1.NSA网络切换4G锚点小区收到终端的测量报告后，根据测量报告中的邻区测量结果选定目标小区；通过X2与目标(站点)小区进行协商，开启切换流程；

2.NSA网络切换类型NSA网络根据MN和SN服务小区的(切换)改变方式有两种方式：站内小区变更、站内切换、进一步划分场景如下表所示：场景实现流程场景11-1

LTE锚点不变，NR站内小区变更1-2

LTE锚点不变，NR站内小区变更场景22-1

LTE锚点站内小区切换，NR不变2-2LTE锚点站间小区x2切换，NR不变2-3LTE锚点站间小区S1切换，NR不变

表1.EN-DC双连接网络切换类型3.NSA网络切换命令在与选定目标(站点)协商完成后，锚点(站点)小区向终端通过RRCConnectionReconfiguration消息下发小区切换(变更)命令；命令中包括：切换方式、类型、4G小区PCI、上(下)行中心频点及小区接入Pramble资源等无线参数；针对EN-DC双连接通知终端在SCG组5G(NR)小区(同步)的非竞争接入方式，小区SSB,初始上行和下行BWP等参数。
