LTE attach 流程

https://www.baidu.com/link?url=FGRpwb9Tk7lPXLFtALkMSIho7tIjooloGcta9p1kVU-xpVEUaR7K92ivvS24WFs0H0IzbCp6kY4aSOavpNatk6BntxqsvuSV6CUIEG3GaDO&wd=&eqid=f164c1390000b2d30000000456e6a493

这是百度文库里的一篇文档，有attach的过程，胜在把UE和eNodeB之间的消息和重要参数做了详解。SRB0, SRB1, SRB2, DRB

RRC Connection Setup has SRB1

RRC Connection Reconfiguration has SRB2 and DRB

里面还有detach的流程，这个不用太多详解。
