移动联通电信获取基站数据库的方案

移动联通电信获取基站数据库的方案在googleAPI里提供了基站信息的获取类TelephonyManager，通过其方法getCellLocation得到CellLocation即可获取到基站相关信息但CellLocation是个抽象类，所以在具体使用时需要判断接入的网络制式来用其子类CdmaCellLocation或GsmCellLocation来强转CdmaCellLocation对应CDMA网，GsmCellLocation对应GSM网三大网络运营商的网络制式对应如下：移动2G网-->GSM移动3G网-->TD-SCDMA电信2G网-->CDMA电信3G网-->CDMA2000联通2G网-->GSM联通3G网-->WCDMA由此可见移动，联通2G网都可使用GsmCellLocation电信2G,3G网则使用CdmaCellLocation那么移动3G和联通3G又当如何其实经本人亲测，移动3G网也可使用GsmCellLocation，听说是TD-SCDMA衍生于GSM，具体原因咱也不用纠结了，反正能用就是了而联通的WCDMA 据说也可使用GsmCellLocation，那姑且就是这样吧，有条件的童鞋试一试吧。对于网络制式的判断调用TelephonyManager.getNetworkType()可有多种情况，如下:NETWORK_TYPE_UNKNOWNNETWORK_TYPE_GPRSNETWORK_TYPE_EDGENETWORK_TYPE_UMTSNETWORK_TYPE_HSDPANETWORKTYPEHSUPA

NETWORKTYPEHSPANETWORK_TYPE_CDMANETWORK_TYPE_EVDO_0NETWORK_TYPE_EVDO_ANETWORK_TYPE_EVDO_BNETWORK_TYPE_1xRTTNETWORK_TYPE_IDENNETWORK_TYPE_LTENETWORKTYPEEHRPD通过对网络类型判断后获取对应基站信息代码片段如下:Html代码publicstaticArrayList<CellIDInfo>getCellIDInfo(Contextcontext)throwsException{2.TelephonyManagermanager=(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);4.ArrayList<CellIDInfo>CellID=newArrayList<CellIDInfo>();CellIDInfocurrentCell=newCellIDInfo();7.inttype=manager.getNetworkType();Log.d(TAG,"getCellIDInfo--> NetworkType="+type);intphoneType=manager.getPhoneType();Log.d(TAG,"getCellIDInfo--> phoneType="+phoneType);12.if(type==TelephonyManager.NETWORK_TYPE_GPRS //GSM网||type==TelephonyManager.NETWORK_TYPE_EDGE||type==TelephonyManager.NETWORK_TYPE_HSDPA){GsmCellLocationgsm=((GsmCellLocation)manager.getCellLocation());

}大家注意看这彳亍holder.put(〃radio_type〃，cellID.get(0).radioType);GSM就用〃gsm〃，CDMA就用〃cdma〃这个千万别搞混了，不然就获取不到信息了值得一提的是C网获取基站再定位那偏差不是一般的大，是恨大，将近1千米了，大概是C网基站较少的缘故吧最后通过经纬度获取地理位置信息，代码如下：Java代码1.publicstaticStringgetAddress(Locationitude)throwsException{StringresultString="";3.4.
