qcom_IMS_conference_call小结

1conference call建立

用QXDM抓qcom log:

1、拨号盘*#*#825364#*#*    ，  进入抓log UI

2、Connectivity-->USB Port Settings -->Diag/Serial/Rmnet选项打钩

3、window界面-->设备-->分配USB设备

4、QPST server configuration-->port-->选择phone使能

5、打开QXDM，File-->load default configuration,出现三个窗口-->再按F1,有第四个窗口-->Options-->communications,弹出窗口，选择port开始抓

　　log，抓log完毕，也在这儿选择端口结束。

6、File-->save items.然后File-->open.只有item view有显示。

7、ctrl+a全选-->鼠标右键refilter items-->Log Packets或Log Packets（OTA）,搜索“SIP”,结束。

如何看关键log:

ctrl+a全选-->鼠标右键Match items-->seach for 关键字“ ”（eg:）-->RegEx Engine:选择None-->确认。

 注意：1、上图的SIP信令不能完全按照时间先后的顺序去对应，要根据信令内容去理解流程，因为实际测试中这些信令log先后顺序会有一些细节的不一致，但大体流程是对的。

的手机主动去挂断，以及的通话，主动挂断方不同，在流程上会有细节的不同。
