基于 AndroidR QCOM IMS CALL 通话流程解析
PS:若有同学想二次修改 笔者可提供下述所有原设计材料 邮箱最后见
一. 一次电话行为的产生 都有哪些 ？？？
首先我们的通信设备与基站是实时的连接
这种场景大概可以理解为
在人多的地方 基站压力大 会表现为 4g上网很慢
坐在高铁上打电话 接入了其他基站 电话会有短暂的卡顿 然后继续通话
等等
这都说明了一次通信行为是由基站有关系
这是一个简单的通话流程 我们把它往业务方向抽象一下
运营商业务系统 你懂的
我们需要了解一下 在手机端 他通信大概有哪些流程
Dialer
packages/apps/Dialer
包含IncallUI 拨号盘等等
Telecomm
packages/services/Telecomm
CallsManager 通话大管家 负责把 Dialer/TeleService进行一次处理 返回给 对应的业务场景
后面才分出来的 作为一个独立的模块单独存在
这是由于在Android Telephony通话模型中它为Dialer和TeleService消息中转站，作为MT与MO消息处理关键入口，承上启下
呈上：相对与Dialer应用而言，发送call状态变化消息给IInCallService服务，并接收Dialer应用发出的call状态控制消息。
启下：相对与TeleService应用而言，Telecom应用继续传递接收到Dialer应用发出的call状态控制消息给IConnectionService服务，并接收TeleService应用发出的Call状态变化传递给Dialer应用。
TeleService
packages/services/TeleService
TeleService -> RIL -> Modem -> 基站
最终将面向业务 转换为 面向协议
监听从RIL上传的协议内容再往上 Telecomm Dialer
数据连接
Framework
// Google定义好接口供运运营商实现
// framework.jar
frameworks/base/telecomm
frameworks/base/telephony
frameworks/opt/telephony
// ims-common.jar
frameworks/opt/net/ims
// ims.apk
// 属于不同平台的实现
vendor/(mtk/qcom)/proprietary/xxx/Ims
RIL
RILJ
java层 为上层提供访问modem的入口和消息接收
RILD
HAL层
RILJ 下发请求 -> RILD 将Request转换为Modem AT 执行发送
Modem上报或者返回消息 -> RILD 处理消息 -> RILJ
无论是 MT 还是 MO 在InCallActivity 拉起之前 都会 进行一次 类似 rtp 的信令交互
因为手机和基站是实时连接 相当于tcp检测线 一直告诉运营商业务系统 我的通信地址是多少 等等
这里由于我对Modem信令交互这块 没有log进行阐述 就用rtp 简单说明一下 即 下述
后续这块可能需要modem的同事帮忙完善一下
A告诉B我支持哪些编解码格式以及地址等等 然后B告诉A我支持哪些编解码格式等等 最后创建 P2P的通信
手机通信也是一样的 所有通信之前 都会有一次 信令交互的过程 具体格式类似下述a=xxx等等
这里的Signal Server Stun Server都在运营商业务系统里面都会有类似的存在

InCallService updateCall 这一步 没有到Dialer进程
在分析代码得出 此时的updateCall 行为只会在Telecomm中消化
我找出这个时间点的log以及代码反复确认 这种场景下 走到updateCall 就结束了
可能是这个状态并不是 bsp/kernel 返回的 所以更新到上层是没有意义的
// todo 此流程可以大致了解下 后续遇到会继续完善MO Call 收到接听上报流程
上述流程可以认为mo行为已经下发 等待mt那边answer/其他回应
首先先告诉state changed UNSOL_RESPONSE_CALL_STATE_CHANGED
// dial -> answer

这是第一通电话 第一个rtp包 视频电话 比较明显 一般 刚接通总会有明显的延时 ps在这里贴一张 应用设计框架图 便于理解
这张图能很清楚的看出来 都有哪些子模块在分工协作
我们到目前为止分析的都是ims call 在网上搜索资料 千万不要和cs call 弄混了
ims ImsPhoneCalltracker
cs GsmCdmaCallTracker 
// 这里RIL会告诉ImsCallSession call的state 发生改变

mt 流程其实和 mo的updateCall 流程基本一致 笔者对整理的内容 进行了评估
只展示qcom内容
ps 后续有机会会补上 但整体上 不影响理解
这张图如果看不清楚 可以看参考链接里 第8个
总结
常用tag
一般的问题 过滤下面几个tag就可以了 能看出什么意思 具体其他参数是什么意思 我也尝试过
分析代码 以及 查询相关信息 但我更愿意查阅 集成方 pdf 当然 如果有更好的方式 可以 与 笔者 分享
按照常用度依次排列

ok，感谢看到这里的小伙伴，其实可以看出 整理这块内容的时间跨度有点大 三个月吧 在整理的过程中 有些东西还是不清楚的 ifly也不提供这块的qcom手册 自己一点一点往上面凑 也参考了很多博客 （绝大多数都是cccv 也没验证过） 这个过程也想过放弃 而且笔者平时还喜欢打个团战 效率不高 但笔者秉承着一个帅哥良好的自我修养 还是坚持整理完了(此处打8.5折) 还有很多细节没有整理到 但笔者认为一般问题分析都是没问题的 如果有好的例子 比较细节性的案例分析 或其他 欢迎和笔者分享 笔者邮箱(to节省不必要的沟通)
