流程图

可以看到信息上报跨了4个模块，没有经过service/Telecom

看关键log方便跟踪

高通私有代码，略。

看到方法名带receive request字样，直译就是收到请求，在响应之后方法名中就会换上类似response。

前面几乎都没什么说的，走一条线就是了，然后经InCallService接口回调到InCallUI

packages/apps/InCallUI

一般客户有需求，要修改界面的话也都是该InCallUI，下层的流程是不动的，因此下面一部分比较重要

android/packages/apps/InCallUI/src/com/android/incallui/InCallVideoCallCallback.java

目前为止传想来的消息都只是MODIFY CALL，并没有携带说是升级还是降级，从下面的方法中可以看到有分开两种情况了。

MT不做任何处理的话15秒后（运营商决定）MO收到运营商发来的响应消息，其中包括InCallVideoCallCallback - onSessionModifyResponseReceived status=5，这个5的定义为VideoProvider.SESSION_MODIFY_REQUEST_REJECTED_BY_REMOTE（5）意为被远端拒绝了可见对于MO来说超时和reject是一样的，而在MT收到的则是VideoProvider.SESSION_MODIFY_REQUEST_TIMED_OUT（4），所以在MT方 reject和time out是区分的。

然后这个error: 28的定义在imsIF.proto中查到，也证明了timeout和reject的。

小结

整个流程中的log不多，主要是底层ImsSenderRxr.java中的log多些，UNSOL_MODIFY_CALL （未处理的新消息），MODIFY_CALL_CONFIRM（MT界面应答），MODIFY_CALL_INITIATE（MO发起），然后InCall中在一些场景中有些log，AnswerPresenter和CallCardPresenter的log。

如果出问题的话也基本上在从底层和上层判断，中间应该不会有什么问题，底层看消息首发，上层看信息显示。Modify Call已经包括upgrade和downgrade，流程整体也是一样，在需要区分的时候会通过callType（CallMofidy）来区分。
