在Android Studio中获取LTE RSRQ，SINR，CQI，CINR和切换信息

Question

我在发布这个问题之前非常搜索。我正在LTE network上进行Android Studio监控和驾驶测试。 我找到了一种使用类RSRP中的方法Asu Level和LTE network衡量getCellSignalStrength()，getCellIdentity()和其他CellInfo测量的方法。但是，I am still searching for a manner to determine or calculate RSRQ, CQI, SINR, SNR, HO total attempts and HO successful attempts。 如果有人能给我答案，我将不胜感激！

这就是我的尝试：

    //start the signal strength listener
    signalStrengthListener = new SignalStrengthListener();

    ((TelephonyManager) getSystemService(TELEPHONY_SERVICE)).listen(signalStrengthListener, SignalStrengthListener.LISTEN_SIGNAL_STRENGTHS);
    tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);


    try {
        cellInfoList = tm.getAllCellInfo();
    } catch (Exception e) {
        Log.d("SignalStrength", "+++++++++++++++++++++++++++++++++++++++++ null array spot 1: " + e);
    }

    try {
        for (CellInfo cellInfo : cellInfoList) {
            if (cellInfo instanceof CellInfoLte) {
                // gets RSRP cell signal strength:
                cellSig = ((CellInfoLte) cellInfo).getCellSignalStrength().getDbm();

                // Gets the LTE cell indentity: (returns 28-bit Cell Identity, Integer.MAX_VALUE if unknown)
                cellID = ((CellInfoLte) cellInfo).getCellIdentity().getCi();

                // Gets the LTE MCC: (returns 3-digit Mobile Country Code, 0..999, Integer.MAX_VALUE if unknown)
                cellMcc = ((CellInfoLte) cellInfo).getCellIdentity().getMcc();

                // Gets theLTE MNC: (returns 2 or 3-digit Mobile Network Code, 0..999, Integer.MAX_VALUE if unknown)
                cellMnc = ((CellInfoLte) cellInfo).getCellIdentity().getMnc();

                // Gets the LTE PCI: (returns Physical Cell Id 0..503, Integer.MAX_VALUE if unknown)
                cellPci = ((CellInfoLte) cellInfo).getCellIdentity().getPci();

                // Gets the LTE TAC: (returns 16-bit Tracking Area Code, Integer.MAX_VALUE if unknown)
                cellTac = ((CellInfoLte) cellInfo).getCellIdentity().getTac();


            }
        }
    } catch (Exception e) {
        Log.d("SignalStrength", "++++++++++++++++++++++ null array spot 2: " + e);
    }
}


@Override
protected void onPause() {
    super.onPause();

    try{
        if(signalStrengthListener != null){tm.listen(signalStrengthListener, SignalStrengthListener.LISTEN_NONE);}
    }catch(Exception e){
        e.printStackTrace();
    }
}


@Override
protected void onDestroy() {
    super.onDestroy();

    try{
        if(signalStrengthListener != null){tm.listen(signalStrengthListener, SignalStrengthListener.LISTEN_NONE);}
    }catch(Exception e){
        e.printStackTrace();
    }
}


private class SignalStrengthListener extends PhoneStateListener{

    @Override
    public void onSignalStrengthsChanged(android.telephony.SignalStrength signalStrength) {

        ((TelephonyManager) getSystemService(TELEPHONY_SERVICE)).listen(signalStrengthListener, SignalStrengthListener.LISTEN_SIGNAL_STRENGTHS);

        tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        /*
        int a = tm.getNetworkType();
        CellLocation cl = tm.getCellLocation();
        String did = tm.getDeviceId();
        String sv = tm.getDeviceSoftwareVersion();
        String netOp = tm.getNetworkOperatorName();
        */




        String ltestr = signalStrength.toString();
        String[] parts = ltestr.split(" ");
        String cellSig2 = parts[9];

        try {
            cellInfoList = tm.getAllCellInfo();
            for (CellInfo cellInfo : cellInfoList) {
                if (cellInfo instanceof CellInfoLte) {
                    // cast to CellInfoLte and call all the CellInfoLte methods you need
                    // gets RSRP cell signal strength:
