There are a couple pieces to the puzzle for an application to leverage location data from the network.

1. Determine location
2. Convert lat/lon into a street address, map, etc...
3. Deliver data based on this location to the handset

Starting at the top, Openwave Location Studio is the developer's interface into the location information that the wireless operators around the world have access to. Location access is restricted for privacy reasons. Developers must be granted access to Location Studio, and an end user must grant permission to disclose their location information. For enterprise customers, carriers may grant access in advance for device owned by the corporation (i.e. a taxi dispatch company would be able to query the location of every device that it pays the bill for). For developers Openwave has created a single developer account that can query the location of devices in our development environment. To be clear, the locations of the devices in Openwave Location Studio are not real, in that they are not being extracted from the network, but the response that Location Studio provides back to developers is "real".
To access Location Studio, use the id infoservdemo1 and a password of infoservdemo1 The code that actually results in obtaining the latitude and longitude of the subscriber is as simple as:

	 //retrieve the latitude and longitude
	  WLP10Position[] positions = responseL.getWLP10Position();
        if ( positions.length > 0 )
           {
               
             x = positions[0].getLatitude();
             y = positions[0].getLongitude();
           }
        }

...
$x = $cgiVars{"x"};
$y=$cgiVars{"y"};

if ($x < 0.0){
$url="http://sgp3.na.developer.webraska.com/gns?mode=server_1.3&user=javaone&pass=speM4f2a&geolang=en&function=revgeo&wgs84=".$x."|".$y;
 }else{
  $url="http://sgp3.eu.developer.webraska.com/gns?mode=server_1.3&user=javaone&pass=speM4f2a&geolang=en&function=revgeo&wgs84=".$x."|".$y;

}
#retrieve response from location server (Webraska) and store the info in @response
if (&AppUtils::HTTPConnectAndBuffer($url, \@response)) {

public void doGet(HttpServletRequest request, 
                    HttpServletResponse response)
            throws IOException, ServletException {

                // create a connection to an relay and send the MM
                RelayConnection conn = RelayConnection.createSender( mmscUrl, userName, password );
                conn.setWeakCN( true );
