如何让现有GSM网络的列表？ [英] how to get a list of available gsm networks?

问题描述

我目前正在写关于Android 2.1的一些片code的是应该测量GSM信号的信号强度。
我需要的是某种名单以某种匹配相应的信号strengthes网络ID ...
我走到这一步：

i'm currently writing on some piece of code in android 2.1 that is supposed to measure the signal strength of the gsm signals. what i need is some kind of list with some kind of network IDs matching the corresponding signal strengthes... i got this far:

public class main extends Activity {
    TelephonyManager telManager;
    GSMListener gsmListener;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        gsmListener = new GSMListener();

        telManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        telManager.listen(gsmListener ,PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);

    }

    private class GSMListener extends PhoneStateListener {
        /* Get the Signal strength from the provider, each time there is an update */
        @Override
        public void onSignalStrengthsChanged(SignalStrength signalStrength) {
            super.onSignalStrengthsChanged(signalStrength);

            Toast.makeText(main.this, "GSM Cinr: " + signalStrength.getGsmSignalStrength(), Toast.LENGTH_SHORT).show();
        }
    };
}

但在这一点上，我不知道是否有网络ID就像BSSID的WiFi网络？这是怎么与GSM处理？我需要确定GSM网络我得到的信号强度。

but at this point, i wonder if there's network-id like the bssid for wifi networks? how is this handled with gsm? i need to identify the gsm network i'm getting the signal strength of.

编辑：

由网络ID，意思是小区ID。我需要的是在范围内 *所有可用* GSM网络及其接收质量的列表。操作-id是没有太大的兴趣给我的，因为我需要确定细胞和网络，我碰到的信号强度。

by "network-id", meant "cell-id". what i need is a list of *all available* gsm networks in range and their reception quality. the operator-id is not of much interest to me, as i need to identify cell AND network, i'm getting the signal strength from.

推荐答案

每个运营商都有一个唯一的ID，一个叫PLMN（公共陆地移动网络）的5位数字。

Every operator has a unique ID, a 5 digit number called PLMN (Public land mobile network).

这号由后面3个数字的MCC（移动国家code）的2位MNC（移动网code）。

That number consists of a 3-digit MCC (Mobile Country Code) followed by a 2-digit MNC (Mobile Network Code).

借助维基百科列表是一个相对完整的清单。

The wikipedia list is a relatively complete list.
