还有你可以使用以下示例代码：

private static String获取连接字符串(){
字符串连接字符串=“”；
if(WLANInfo.getWLANState()==WLANInfo.WLAN_STATE_CONNECTED){
连接字符串=“；接口= wifi”；
}

 else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS){
     connectionString = ";deviceside=false";
}
    else if((CoverageInfo.getCoverageStatus() & CoverageInfo.COVERAGE_DIRECT)==CoverageInfo.COVERAGE_DIRECT){
        String carrierUid=getCarrierBIBSUid();
        if(carrierUid == null) {
            connectionString = ";deviceside=true";
        }
        else{
             connectionString = ";deviceside=false;connectionUID="+carrierUid + ";ConnectionType=mds-public";
            }               
        }
 else if(CoverageInfo.getCoverageStatus() == CoverageInfo.COVERAGE_NONE)
    {

    }
return connectionString;
}
