3、从主被叫的KPI统计中观测CSFB是否统计正常？
4、从主被叫的CSFB信令流程来看，主被叫的CSFB信令流程是否正常？
一定要查看主被叫的CSFB的起呼、4G网络RRC释放、4G重选至3G、3G的RRC\RAB\Alerting的完整起呼流程。
验证完全完整后，才算合格。
数据统计
1、单站报告中CSFB成功率统计
2、CSFB的log记录备份
3、若存在测试不成功现象，可初步按照第4节指导进行初步分析原因，待调整后复测
分析原因一定要细分类，描述清晰，复测一定要确定故障消除
三、正常CSFB信令流程
3.1.主叫主要流程
当开机做主叫时，UE首先在FDD_LTE注册（attach）,完成注册后进行拨号；
通过E_nodeB上发CSFB请求；
其主要流程如下：
开机注册（attach）
注册请求消息AttachRequest（层三消息RRCConnectionRequest）由UE发出（消息属NAS层），请求中包括UE注册的小区，UE支持的加密算法和方式；
联合注册的4G（TAC）和3G（LAC/RAC）与ClassMark;
