rrc建立后，security模式启动后的radio link中断，但是还没有完全disconnect的情况，比如切换后目标小区信号变差，从而导致radiolink短暂中断，但是还没有超过定时器的时间，如果信号编号会重新连接，还有的地方，上行干扰严重，也会频繁reestablish
1.RRC重配置失败；2.切换失败；3.无线链路失败；4.完整性保护失败；
1)如果RRC Connection Reconfiguration中包含mobilityControlInfo，那主要作用就是eNodeB发切换命令给UE执行切换；2)如果RRC Connection Reconfiguration紧跟在RRC Connection Re-establishment之后，其作用通常都是重建SRB2和DRB；3)如果RRC Connection Reconfiguration中包含measConfig，那其主要作用就是进行测量配置；...
