最近在調(diào)試軟件無(wú)線電平臺(tái)之間的互聯(lián)互通，成功調(diào)通了Amari MME + OAI eNB + srsUE。不清楚這些SDR LTE平臺(tái)的可以點(diǎn)擊我的博客了解 http://blog.csdn.net/jxwxg/article/details/53026659。
調(diào)通之后，我分別抓取了Amari MME側(cè)信令流程Log，OAI eNB側(cè)的信令流程Log和srsUE側(cè)信令流程Log。主要包括eNB與MME的信令交互，UE隨機(jī)接入，鑒權(quán)等信令交互。
歡迎有需要的朋友下載。下載之后建議使用notepad++打開。
