1、看1OG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1OG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1NSA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11-11TE锚点不变,NR站内小区
