2、hmentcause：建立原因，有多种类型，PS业务为registration。ProtocolErrorIndicator：协议错误标识，用来标明是否有协议错误发生。测量IE：给出在Uu接口上的测量结果；InitialUECapability：UE能力；RRCConnectionRequestIE如下：valueUL-CCCH-Message:=messagerrcConnectionRequest:initialUE-Identitytmsi-and-LAI:标注UE TMSI和LAI,经验证LAI为手机储存的tmsiB,laiplmn-Identitymcc4,6,0,mnc0,0,la
