symbian区分当前用户SIM卡是移动还是联通

     首先介绍下背景知识:

        SIM卡唯一标识:IMSI 国际移动用户识别码(IMSI:International Mobile Subscriber Identification Number)是区别移动用户的标志,储存在SIM卡中,可用于区别移动用户的有效信息。IMSI由MCC、MNC、MSIN组成,其中MCC为移动国家 号码,由3位数字组成,唯一地识别移动客户所属的国家,我国为460;MNC为网络id,由2位数字组成,用于识别移动客户所归属的移动网络,中国移动为 00,中国联通为01;MSIN为移动客户识别码,采用等长11位数字构成。唯一地识别国内GSM移动通信网中移动客户。所以要区分是移动还是联通,只需 取得SIM卡中的MNC字段即可,在S60 2nd和3rd上都提供这样的api。

 

Code: // TelephonyAO.h

#include **

#include **

Class CTelephonyAO : public CActive

{

public:

     static CTelephonyAO* NewL();

    void GetNetWorkId(TDes& aNetworkId);

public:

    ~CTelephonyAO();

protected:

    void DoCancel();

    void RunL(); private:

    CTelephonyAO();

    void ConstructL();

    void GetNetWorkInfo();

private:

    CTelephony* pTelephony_;

    CTelephony::TCancellationRequest cancelRequest_;

    CTelephony::TNetworkInfoV1 networkInfo_;

    CTelephony::TNetworkInfoV1Pckg networkInfoPkg_;

};

 

/* .cpp */ // TelephonyAO.cpp

 

#include "TelephonyAO.h"

CTelephonyAO::CTelephonyAO() : CActive(EPriorityStandard), networkInfoPkg_(networkInfo_)

{

     CActiveScheduler::Add(this);

}

 

 CTelephonyAO::~CTelephonyAO()

{

    delete pTelephony_;

}

 

void CTelephonyAO::ConstructL()

{

    pTelephony_ = CTelephony::NewL();

 }

 

CTelephonyAO* CTelephonyAO::NewL()

{

    CTelephonyAO* pSelf = new(ELeave) CTelephonyAO;

    CleanupStack::PushL(pSelf);

    pSelf->ConstructL();

    CleanupStack::Pop();

    return pSelf;

}

 

void CTelephonyAO::RunL()

{

    CActiveScheduler::Stop();

}

 

void CTelephonyAO::DoCancel()

{

    pTelephony_->CancelAsync(cancelRequest_);

}

 

void CTelephonyAO::GetNetWorkInfo()

{

    Cancel();

    cancelRequest_ = CTelephony::EGetCurrentNetworkInfoCancel;

    pTelephony_->GetCurrentNetworkInfo(iStatus, networkInfoPkg_);

    SetActive();

    CActiveScheduler::Start();

}

 

void CTelephonyAO::GetNetWorkId(TDes& aNetworkId)

{

    GetNetWorkInfo();

    aNetworkId = networkInfo_.iNetworkId;

}

 

用法:

TBuf<4> networkId;

CTelephonyAO* pTelephony = CTelephonyAO::NewL();

CleanupStack::PushL(pTelephony);

pTelephony->GetNetWorkId(networkId);

CleanupStack::PopAndDestroy(pTelephony); // 下面通过判断networkId是01还是00即可区分移动和联通

(注: 移动或者联通新号码断非00和01,可以根据具体的SIM卡测试归类一下)
