PS业务全过程介绍

一、RRC连接过程
当RNC接收到UE的RRC CONNECTION REQUEST消息，由其无线资源管理模块RRM根据特定的算法确定是接受还是拒绝该RRC连接建立请求，如果接受，则再判决是建立在专用信道还是公共信道。
主要参数：Initial UE Identity：初始的UE标识，如IMSI，TMSI等参数，用来让网络识别发送该建立请求消息的UE；Establishment cause：建立原因，有多种类型，PS业务为registration。Protocol Error Indicator：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；Initial UE Capability：UE能力；

RRC Connection Request IE 如下：
value UL-CCCH-Message ::=
{
message rrcConnectionRequest :
{
initialUE-Identity tmsi-and-LAI : 标注UE TMSI和LAI,经验证LAI为手机储存的

{
tmsi '01100000 10001110 00100011 00001110'B,

},
mnc
{
0,
0
}
},
lac '10100101 00001011'B
}
},
establishmentCause registration,建立原因：注册，如果不需要ATTACH，就为交互类

protocolErrorIndicator noError,
measuredResultsOnRACH 传输信道是RACH

}

initialUE-Identity tmsi-and-LAI :
{
tmsi '01100000 10001110 00100011 00001110'B,同RRC Connection Request 标注UE TMSI 和LAI

timerRST tr500,该定时器用于触发RESET PDU 重传 此处为500ms

max-RST rst32,发送RESET PDU的最大次数，当等于该值时将向上层上报不可恢复的错误，此处为32次。
