过去十年来,有几个人提出了类似的问题,但没有人有任何答案。我需要编写一个android应用程序来收集和存储rsrp、rsrq、cinr和手机id。答案需要尽可能精确,因为我需要对这些值进行后期处理统计(我正在三星galaxy s5上进行测试)。
有人知道如何使用电话管理器或CellSignalStrengthlet来获取RSRP吗?或者还有其他更好的方法来获得rsrp吗?
到目前为止,我所能做的最好的事情是使用phoneStateListener和telephonymanager来获取rssi值,但是rssi对于我的统计数据是无用的:

    package com.pscr.jparks.signalstrength;

    import android.app.Activity;
    import android.os.Bundle;
    import android.telephony.PhoneStateListener;
    import android.telephony.TelephonyManager;
    import android.widget.TextView;
    /*
    TS 27.007 8.5
    Defined values
    <rssi>:
    0 -113 dBm or less
    1 -111 dBm
    2...30 -109... -53 dBm
    31 -51 dBm or greater
    99 not known or not detectable
    */

    public class SignalStrengthActivity  extends Activity {

        SignalStrengthListener signalStrengthListener;
        TextView signalStrengthTextView;


        @Override
        public void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);

            //setup content stuff
            this.setContentView(R.layout.signal_strength);
            signalStrengthTextView = (TextView) findViewById(R.id.signalStrengthTextView);

            //start the signal strength listener
            signalStrengthListener = new SignalStrengthListener();
            ((TelephonyManager) getSystemService(TELEPHONY_SERVICE)).listen(signalStrengthListener, SignalStrengthListener.LISTEN_SIGNAL_STRENGTHS);
        }


        private class SignalStrengthListener extends PhoneStateListener {
            @Override
            public void onSignalStrengthsChanged(android.telephony.SignalStrength signalStrength) {

                // get the signal strength (a value between 0 and 31)
                int strengthAmplitude = signalStrength.getGsmSignalStrength();

                //do something with it (in this case we update a text view)
          signalStrengthTextView.setText(String.valueOf(strengthAmplitude));
          super.onSignalStrengthsChanged(signalStrength);
            }
        }
    }

如果有人解决了这个问题,或者找到了答案(我到处找过!),请告诉我!

最佳答案

更新:

TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
List<CellInfo> cellInfoList = tm.getAllCellInfo();
for (CellInfo cellInfo : cellInfoList)
{
    if (cellInfo instanceof CellInfoLte)
    {
        // cast to CellInfoLte and call all the CellInfoLte methods you need
        ((CellInfoLte)cellInfo).getCellSignalStrength().getDbm();
    }
}
