LTE 信令流程log 之 Amarisoft MME

最近在研究SDR LTE系统之间的互联互通，成功调通了Amari MME + OAI eNB + srsUE。不知道这些SDR LTE平台的可以参见我的博客http://blog.csdn.net/jxwxg/article/details/53026659。

调通之后，抓取了MME，eNB和UE侧的信令流程log，流程包括了eNB与MME的连接，UE随机接入，UE鉴权等过程。由于Log内容较多，本博客只介绍Amari MME侧Log信息。OAI eNB的Log信息可以点击 http://blog.csdn.net/jxwxg/article/details/53999085 。 srsUE侧的信令流程Log信息可以点击 http://blog.csdn.net/jxwxg/article/details/53999163。
