通话主要是针对拨出的电话。想要在接通的时候给出震动提示那么就需要知道通话何时是被接通的，这样才能在进入该状态后给出提示。但SDK中并没有直接获得这种状态的方式。SDK中的TelephonyManager类提供了3种电话的状态.
CALL_STATE_IDLE 空闲状态
CALL_STATE_OFFHOOK 摘机状态
CALL_STATE_RINGING 响铃状态
拨出电话的时候,会输入这么几条log，拨号->提醒->活动
拨号：GET_CURRENT_CALLS id=1,DIALING
提醒：GET_CURRENT_CALLS id=1,ALERTING
活动：GET_CURRENT_CALLS id=1,ACTIVE
电话接通时会进入活动状态,并会输出：GET_CURRENT_CALLS id=1,ACTIVE 这条log。
在拨号开始到电话接通这段时间内会经过多次的拨号->提醒->活动，仅当话筒中嘟声响起后GET_CURRENT_CALLS这条日志会锁定在ALERTING，在通话接通之前会出现多次的GET_CURRENT_CALLS ACTIVE 这样的日志，而仅有一次是电话接通产生的。不能只是单纯的抓取GET_CURRENT_CALLS ACTIVE 这样的信息来判断。

2 Modem侧
断开了UE与LTE的RRC
连接到CDMA
2.1 主机打电话挂电话
其中SETUP的参数中有被叫电话号码
挂断电话Disconnect
打完电话后释放与CDMA的RRC连接
再进行TAU驻到4G
第二次测量报告的参考信号的功率值30-140=-110刚好等于门限值，故而再次配置，但由下图展示的结果可知仍不理想，故而进行了网络切换，切换到CDMA。
2.2 打电话对方挂断
对方挂断电话DISCONNECT，本机挂断时:
断开与CDMA的RRC连接
2.3 接电话对方挂断
在转换到CDMA制式后，连接了RRC后，接收来电
2.4 接电话本机挂断
流程与接电话对方挂断相同，不同在于信令方向,如DISCONNECT中,被叫:
