利用COM口来获取CELLID，并不保证所有的设备都支持。

测试平台：

VS2005 + WM 6.0

开发语言：

C++

typedef

struct

{

char CountryCode[12];

char AreaCode[4];

char NetworkCode[4];

char CellID[4];

} TCREG_DATA;

获取基站信息：

复制到剪贴板  C/C++代码

void Get_Cellid(void)

{

char m_sTemp[12] = {0};

strcat(m_sTemp,"COM");

for(int i = 9; i > 0; -- i)

{

char ch1;

_itoa(i,&ch1,10);

strcat(m_sTemp,&ch1);

strcat(m_sTemp,":");

TCREG_DATA* pData = (TCREG_DATA*)GetCREG(m_sTemp);

if(!pData)

continue;

char szNum1[8] = {0};

char szNum2[8] = {0};

strcpy(szNum1,pData->AreaCode);

strcpy(szNum2,pData->CellID);

int iLac = (int)strtol(szNum1,NULL,16);

int iId  = (int)strtol(szNum2,NULL,16);

if (iLac && iId)

{

sprintf(m_sCell.LAC,"%06d", iLac );

sprintf(m_sCell.ID,"%06d", iId  );

break;

}

}

}
