LTE Access Stratum Log Analysis

1. PSS主同步信號數據捕獲 （Initial Acquisition）

2. 隨機接入信道過程 （RACH Procedure）

前面文章見博文：
【LTE】Qualcomm LTE Packets log 分析（一）LTE Access Stratum Log Analysis

連載中。。。

3. SRB1消息建立 （SRB1 Establishment）

在LTE信令中存在三個,分別是 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：需要建議，用于NAS層的消息
