LTE Access Stratum Log Analysis
1. PSS主同步信号数据捕获 （Initial Acquisition）
2. 随机接入信道过程 （RACH Procedure）
前面文章见博文：
【LTE】Qualcomm LTE Packets log 分析（一）LTE Access Stratum Log Analysis
连载中。。。
3. SRB1消息建立 （SRB1 Establishment）
在LTE信令中存在三个,分别是 SRB0、SRB1、SRB2
SRB0：不需要建立，上下行就有的
SRB1：需要建立，它主要用于上下行的信令 和 部分NAS 信令
SRB2：需要建议，用于NAS层的消息
