    String connectionString="";
    if(WLANInfo.getWLANState()==WLANInfo.WLAN_STATE_CONNECTED){
        connectionString="?;interface=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;
    }
