本文详细解析了在Android QCRIL中发送CDMA短信的过程。从RIL.java的RIL_REQUEST_CDMA_SEND_SMS请求开始，经过qcril.c的onRequest处理，包括请求检查、参数存储、日志打印、QMI相关操作，最终调用qcril_qmi_sms_unsolicited_indication_cb_helper进行响应处理，并通过qcril_sms_convert_mt_cdma_sms_to_RIL_format将QMI格式的短信转化为RIL格式，完成发送流程。

1、发送短信

RIL.java发送RIL_REQUEST_CDMA_SEND_SMS 请求后，qcril.c进入onRequest进行处理。

[00063/02]MSG 02:35:24.035Android QCRIL/High qcril.c 05445 RIL[1][main] onRequest: UI --- RIL_REQUEST_CDMA_SEND_SMS (87) ---> RIL [RID 1, token id 11424, data len 372]

在onRequest中，先检查该request是否支持。qcril_request_check_if_suppressed判断该request是否在qcril_request_suppress_list列表中。

[00063/00]MSG 02:35:24.035Android QCRIL/Low qcril.c 11222 RIL[1][main] qcril_request_check_if_suppressed: function exit with ret 0

下面会先后判断是否RIL_REQUEST_DIAL或RIL_REQUEST_SETUP_DATA_CALL、RIL_REQUEST_RADIO_POWER或RIL_REQUEST_SCREEN_STATE、RIL_REQUEST_SET_MUTE。（这里暂时不分析这几个request，先略过）。如果不是这几个request，则QCRIL_LOG_CF_PKT_RIL_REQ（这个是干什么的，与QCRIL_LOG_DEBUG有什么区别）

[00063/02]MSG 02:35:24.035Android QCRIL/High qcril.c 05508 RIL[1][main] onRequest: data stream received from telephony

qcril_qmi_print_hex打印qmi日志。

接下来会针对RIL_REQUEST_OEM_HOOK_RAW进行处理（这里略过）。

接下来开始处理request，先调用qmi_ril_fw_android_request_flow_control_info_lock来设置锁。

[00063/02]MSG 02:35:24.036Android QCRIL/High qcril.c 05550 RIL[1][main] onRequest: android request id 87

[00063/02]MSG 02:35:24.036Android QCRIL/High qcril.c 05557 RIL[1][main] onRequest: handling caps 51200060 hex

调用qmi_ril_fw_create_android_live_params_copy函数存储参数到android_request_param_copy中。

QCRIL_LOG_FUNC_ENTRY();//打印函数进入的日志：

[00063/00]MSG 02:35:24.036Android QCRIL/Low qcril.c 09503 RIL[1][main] qmi_ril_fw_create_android_live_params_copy: function entry

QCRIL_LOG_FUNC_RETURN_WITH_RET( (int)res );//打印函数退出日志

[00063/00]MSG 02:35:24.036Android QCRIL/Low qcril.c 10460 RIL[1][main] qmi_ril_fw_create_android_live_params_copy: function exit with ret 2

QCRIL_LOG_DEBUG( "method %d, datalen %d", (int)request_param_method, datalen );

[00063/02]MSG 02:35:24.037Android QCRIL/High qcril.c 05576 RIL[1][main] onRequest: method 2, datalen 372

调用qmi_ril_fw_android_request_flow_control_find_busy_kind（？这个函数）

[00063/00]MSG 02:35:24.037Android QCRIL/Low qcril.c 08760 RIL[1][main] qmi_ril_fw_android_request_flow_control_find_busy_kind: function entry

[00063/02]MSG 02:35:24.040Android QCRIL/High qcril.c 08404 RIL[1][main] qmi_ril_fw_android_request_render_execution: rendering exec for token id 11424

//调用qcril_execute_event

[00063/00]MSG 02:35:24.040Android QCRIL/Low qcril.c 06116 RIL[1][main] qcril_execute_event: function entry

//do dispatch internally

QCRIL_LOG_INFO("Dispatching event/android request..");

error = qcril_dispatch_event( entry_ptr, params_ptr );

[00063/01]MSG 02:35:24.040Android QCRIL/Medium qcril.c 06233 RIL[1][main] qcril_execute_event: Dispatching event/android request..

进入qcril_qmi_sms.c的qcril_sms_request_cdma_send_sms方法

[00063/00]MSG 02:35:24.040Android QCRIL/Low qcril_qmi_sms.c 03085 RIL[1][main] qcril_sms_request_cdma_send_sms: function entry

qcril_sms_request_cdma_send_sms的处理：

第一步：获取LTE_SMS状态和voLTE状态（分别通过方法qcril_qmi_nas_fetch_lte_sms_status和qcril_qmi_nas_is_voice_over_lte_registered，这两个方法都是根据nas_cached_info值来判断，qcril_qmi_nas.c文件中）

qcril_qmi_nas_fetch_lte_sms_status( &lte_sms_status_valid, &lte_sms_status);

is_voice_over_lte = qcril_qmi_nas_is_voice_over_lte_registered();

[00063/00]MSG 02:35:24.040Android QCRIL/Low qcril_qmi_nas.c 43095 RIL[1][main] qcril_qmi_nas_is_voice_over_lte_registered: function exit with ret 0 //voLTE未注册

第二步：检查3gpp2 的wms service服务是否没有OK（下面日志显示已经OK），并且voLTE也没有注册，此时返回失败

if (!wms_ready_atleast_limited_3gpp2() &&

!(is_voice_over_lte && lte_sms_status_valid && (NAS_SMS_STATUS_1X_V01 == lte_sms_status))

)

[00063/00]MSG 02:35:24.040Android QCRIL/Low qcril_qmi_sms.c 08301 RIL[1][main] wms_ready_atleast_limited_3gpp2: function entry

[00063/02]MSG 02:35:24.040Android QCRIL/High qcril_qmi_sms.c 08318 RIL[1][main] wms_ready_atleast_limited_3gpp2: WMS service is ready for atleast limited/full 3GPP2, WMS_SERVICE_READY_STATUS_3GPP_AND_3GPP2

[00063/00]MSG 02:35:24.040Android QCRIL/Low qcril_qmi_sms.c 08327 RIL[1][main] wms_ready_atleast_limited_3gpp2: function exit with ret 1

第三步：检查SMS数据是否为NULL，是则返回failure。

第四步：在IMS未注册时，检查MO SMS通路是否被封锁。是则返回failere。通过方法qmi_ril_block_mo_sms_on_1x进行判断。

[00063/00]MSG 02:35:24.040Android QCRIL/Low qcril_qmi_sms.c 07956 RIL[1][main] qmi_ril_block_mo_sms_on_1x: function entry

[00063/01]MSG 02:35:24.046Android QCRIL/Medium qcril_qmi_sms.c 07962 RIL[1][main] qmi_ril_block_mo_sms_on_1x: transport layer info status block 0, valid 0 value 0
