How to programmatically connect to the internet in blackberry

In blackberry you can connect to internet in 7 ways. For establishing connection you have to specify which way you want to connect to the internet.

HttpConnection hconn = hconn = (HttpConnection) Connector.open(url + connectionstring);

1.       MDS (mobile data service): if no connection string is given, this is a default connection.

A. coverage check: CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_MDS)              

B. connection string: “;deviceside = false”

2.       BIS (blackberry internet services): if your application is approved from the blackberry, your application will connect to server regardless of internet configuration of device.

A.      Coverage check: CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT)

B.      Connection string: “;deviceside = true”

3.       Direct TCP: This method depends on carrier and supports limited roaming.

A. Coverage check: CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT)

B. Connection string: “deviceside = true;apn=; tunnelauthusername=; tunnelauthpassword=”

4.       WAP 2: It will connect through wap gateway and connection string provided by service book’s connectionUID.

A.Coverage check: CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT)

B.connection string: ;deviceside=true" + ";ConnectionUID=" +wapRecord.getUid()

5.       WAP 1.0:

A. Coverage check: CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT)

B. connection  String: “;deviceside = true; ;WapGatewayIP=;WapGatewayAPN=;WapGatewayPort=;WapSourceIP=;WapSourcePort=;TunnelAuthUsername=;TunnelAuthPassword=;WapEnableWTLS=true/false”

6.       WiFi:

A.      CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT, RadioInfo.WAF_WLAN, false)

B. Connection string: “;interface = wifi”

7.       Magic word(";ConnectionType=mds-public”): This word is not documented anywhere in blackberry docs but it works for approx 90% of devices.

A.      Coverage check: CoverageInfo.isCoverageSufficient(CoverageInfo.COVERAGE_DIRECT)

B.      Connection string: “;deviceside=false"+mdspubRecord.getUid()+ ";ConnectionType=mds-public”

Getting uid from service book:

ServiceBook sb = ServiceBook.getSB();

ServiceRecord[] records = sb.getRecords();

ServiceRecord wapRecord;

ServiceRecord mdspubRecord;

String cid;

String uid;

for (int i = 0; i < records.length; i++) {

                                                ServiceRecord myRecord = records[i];

                                                if (myRecord.isValid() && !myRecord.isDisabled()){

                                                                cid = myRecord.getCid().toLowerCase();

                                                                uid = myRecord.getUid().toLowerCase();

                                                                if(cid.indexOf("ippp") != -1 && myRecord.getName().indexOf("BIBS") != -1){

                                                                mdspubRecord = myRecord

                                                                }

                                                                else if (cid.indexOf("wptcp") != -1 && uid.indexOf("wifi") == -1 && uid.indexOf("mms") == -1) {

                                                                                wapRecord = myRecord;

                                                                }

                                                }

                                }
