来电:
1. PsCBackCallIncoming()
ProcessIncomingEvents(CM_PS_CALL_INCOMING, info);
2.ProcessIncomingCallEvent(info)
AddNewCallInfo()在这里,cm_p->state_info.AllCalls[index].group_id = GetUnUsedGroupID();
如果是MO,那么就先设置为255,然后在PsCBackSetCallFeature( )中在设置为GetUnUsedGroupID()
CMSetupAlertForMT(); 准备提示信息
3. mmi_gsm_ring_ind()
mmi_ucm_ring_ind_struct ring_ind;
装载ring_ind
mmi_ucm_dispatch_ind(MMI_UCM_RING_IND, (void *)&ring_ind);
4. mmi_ucm_ring_ind(void *act_struct) 参数就是上面的ring_ind
如果(当前没有OUTGOING, INCOMING group,不存在紧急电话,不是黑名单号码)
{
mmi_ucm_sync_call_list(ind->call_list); 同步cm_p与g_ucm_p
把参数带进来的消息拷贝到g_ucm_p->mo_mt_display和g_ucm_p->call_misc.l4c_info中
mmi_ucm_entry_marker()
mdi_audio_stop_all()
}
否则 //自动拒接来电
{
mmi_ucm_pre_send_req(MMI_UCM_AUTO_REJECT, &(ind->uid_info), NULL, NULL);
mmi_ucm_pre_send_req(MMI_UCM_FORCE_RELEASE, &(ind->uid_info), NULL, NULL);
}
5. mmi_ucm_entry_incoming_call()
根据g_ucm_p->mo_mt_display,设置一些提示信息:tone id, path, image……
ShowCategory17Screen()
注册按键相应:
任意键接听:mmi_ucm_incoming_call_sendkey()
右软件,END键拒接:mmi_ucm_incoming_call_endkey()
SEND键接听:mmi_ucm_incoming_call_endkey()
mmi_ucm_play_incoming_tone()分2中:ring tone, wait tone
拒接来电
1.mmi_ucm_incoming_call_endkey()
mmi_ucm_stop_incoming_tone()
如果已经启动自动接听,则停止定时器UCM_AUTO_ANSWER_TIMER
mmi_ucm_end_single_action_with_index(groupIndex, 0)
2. mmi_ucm_end_single_action_with_index( )
mmi_ucm_id_info_struct actionId;
显示processing….
装载actionId
mmi_ucm_pre_send_req(MMI_UCM_END_SINGLE, &actionId, NULL, NULL);
3. mmi_ucm_pre_send_req( )
mmi_ucm_single_call_struct singleReq;
用上面的actionId装载singleReq
mmi_ucm_send_req(op_code, first_ptr->call_type, &singleReq);
4. mmi_ucm_send_req( )
mmi_gsm_ucm_act_req(MMI_UCM_END_SINGLE, act_struct);
5. mmi_gsm_ucm_act_req( )
设置:cm_p->ucm_action_type = MMI_GSM_UCM_NORMAL, cm_p->ucm_operation = MMI_GSM_UCM_END_SINGLE
mmi_gsm_end_single(act_struct);
6. mmi_gsm_end_single( ) 所有的挂断电话都是在这里处理
由于此时只有一通来电,因此执行:else if(GetTotalCallCount() == 1 && GetCurrentState() == CM_INCOMING_STATE) 这个分支
SetCallflag(CM_HANGUP_REQUESTED)
MakePsAthRequest((void*)PsCBackIncomingCallRejected);
7. MakePsAthRequest( )
发送消息:PRT_ATH_REQ
athReq->op_code = L4C_DISCONNECT_NONE;
L4C返回消息:PRT_ATH_REQ_SUCCESS,进入CBACK:
1. PsCBackIncomingCallRejected( )
ProcessIncomingEvents(CM_PS_INCOMING_CALL_REJECTED, info); J进入状态机
g_bUserReject = TRUE;
gIncomingCallDroppedFlag = TRUE
2. ProcessIncomingCallRejected()
装载cm_p->disc_call
ResetCallflag(CM_HANGUP_REQUESTED)
设置CM的状态
PurgeIncomingCallStructure()清除了该来电在cm_p中的信息。但是在cm_p->disc_call中仍然存在
mmi_gsm_release_ind(GetCallEndCause());
mmi_gsm_end_single_rsp(TRUE, NULL);
3.mmi_gsm_release_ind( )
mmi_ucm_release_ind_struct release_ind;
用cm_p->disc_call来装载release_ind
mmi_gsm_get_call_list(release_ind.call_list); 获取cm_p中的电话信息
mmi_ucm_dispatch_ind(MMI_UCM_RELEASE_IND, (void *)&release_ind);
4. mmi_ucm_release_ind()
mmi_ucm_stop_inband_tone();
mmi_ucm_stop_incoming_tone();
