从网上看到很多关于后台发送中英文短信的方法，先自己总结了两种，并予以比较。
方法一
这种方法支持两种编码格式，SMSAL_DEFAULT_DCS(7bit 编码)和SMSAL_UCS2_DCS(Unicode编码)
弊端：1)不可以发送长短信，对于7bit编码最多支持160个字符，对Unicode编码只支持70字符
2）不能得知短信发送的状态，如：是否正在发送，发送完毕等
既然这种方法这么大的弊端，为什么还列出来呢？
原因在于，如果你并不需要频繁的发送短信，而且发送的短信内容相对较少那还是可行的。
BOOL mmi_send_message(S8 *pPhoneNum, S8 *pMessageContent, U8 dcs)
{
mmi_sms_send_msg_req_struct *sendmessage = NULL;
S8 tmp;
U8 i;
U16 msg_len = 0;
if(g_pwr_context.CurrentServiceType != FULL_SERVICE)
{
return FALSE;
}
sendmessage = (mmi_sms_send_msg_req_struct*)OslConstructDataPtr(sizeof(*sendmessage));
sendmessage->ref_count = 1;
sendmessage->msg_len = sizeof(mmi_sms_send_msg_req_struct);
sendmessage->profile = 0;
sendmessage->reply_index = MMI_FRM_SMS_INVALID_INDEX;
sendmessage->para = 0;
memset(sendmessage->sc_addr.number, 0xff, MAX_CC_ADDR_LEN);
sendmessage->sc_addr.length = 0xff;
sendmessage->sc_addr.type = 0xff;
sendmessage->vp = 0xff;
sendmessage->pid = 0xff;
sendmessage->udhi = 0;
sendmessage->seq_num = 0;
memset(sendmessage->msg, 0, SMSAL_MAX_MSG_LEN);
mmi_frm_sms_convert_ascii_num_to_l4_num(&sendmessage->dest, (U8*)pPhoneNum);
if(SMSAL_DEFAULT_DCS == dcs)
{
msg_len = strlen((S8*)pMessgeContent);
}
else
{
msg_len = pfnUnicodeStrlen((S8*)pMessgeContent) * 2;
for(i=0; i<msg_len; i+=2)
{
tmp = pMessageContent;
pMessageContent = pMessageContent[i+1];
pMessageContent[i+1] = tmp;
}
}
if(SMSAL_MAX_MSG_LEN < msg_len)
{
return FALSE;
}
sendmessage->length = msg_len;
memcpy(sendmessage->msg, (U8*)pMessageContent, sendmessage->length);
mmi_frm_sms_send_message(MOD_MMI,
MOD_L4C,
0,
PRT_MSG_ID_MMI_SMS_SEND_MSG_REQ,
(oslParaType*)sendmessage,
NULL);
return TRUE;
}
方法二
这种方法是将所传入的短信内容都转为Unicode编码方式进行发送
弊端：如果是7bit编码的话被转为了Unicode编码，大大减少了发送的内容
优势：支持长短信发送，并且可以明确知道短信发送状态（有回调函数）
void mmi_send_message(S8 *pPhoneNum, S8 *pMessageContent)
{
U8 i;
byte result;
S8 textbufUCS2[(MAX_SMS_CONTENT_LEN+1)*2];
EMSData *pEMS = NULL;
if(g_pwr_context.CurrentServiceType != FULL_SERVICE)
{
return;
}
ReleaseEMSEditBuffer();
pEMS = GetEMSDataForEdit(0, 0);
PendingSaveSendData.mti = SMSAL_MTI_SUBMIT;
memset(PendingSaveSendData.TPUD, 0, sizeof(PendingSaveSendData.TPUD));
for (i = 1; i < mmi_msg_get_seg_num(); i++)
{
PendingSaveSendData.TPUDLen = 0;
PendingSaveSendData.TPUD_p = NULL;
PendingSaveSendData.l4index = SMS_INVALID_INDEX;
PendingSaveSendData.TPUD_udhi = FALSE;
}
memset(textbufUCS2, 0, sizeof(textbufUCS2));
mmi_chset_text_to_ucs2((kal_uint8*)textbufUCS2, sizeof(textbufUCS2), (kal_uint8*)pMessageContent);
result = AppendEMSString(IMM_INPUT_TYPE_SENTENCE,
pEMS,
(U8*)textbufUCS2,
SMSAL_UCS2_DCS,
NULL);
/* mmi_get_sms_segments函数的实现，可以参看手机输入短信的时候右上角显示的可输入的字符个数，例如，如果输入了长短信的话，第一页可以输入160，第二页可是输入146，从第三页之后都是152。这个长短不一和是因为每段短信的头处加入一些数据头，以便进行拼接所用的。
支持的长短信的页数定义在custom\ps\XXX_XX_bb\Customer_ps_inc.h，名称为MMI_SMS_MAX_MSG_SEG
该值默认为4
*/
PendingSaveSendData.totalSegments = mmi_get_sms_segments(pEMS->textLength); //获取短信的段数
if(0xFF == PendingSaveSendData.totalSegments)
{
gb_sending_sms = FALSE;
return;
}
if (result)
{
mmi_frm_sms_send_struct *sendData = OslMalloc(sizeof(mmi_frm_sms_send_struct));
gb_sending_sms = TRUE;
memset((S8 *) sendData,0,sizeof(mmi_frm_sms_send_struct));
memset(sendData->number,0,MAX_DIGITS_SMS);
strcpy((S8 *) sendData->number, (S8*)pPhoneNum);
mmi_frm_sms_send_sms(send_message_callback, MOD_MMI, sendData);
OslMfree(sendData);
return;
}
gb_sending_sms = FALSE;
return;
}
//发送短信完成后的回调函数
void send_message_callback(void *number, module_type mod, U16 result)
{
U16 currentSCRID;
gb_sending_sms = FALSE;
mmi_frm_sms_delete_screen_history();
currentSCRID = GetActiveScreenId();
if((currentSCRID == SCR_ID_MSG_SENDING)
|| (currentSCRID == SCR_ID_MSG_PROCESSING))
{
GoBackHistory();
}
return;
}
