Description

The RConnectionMonitor class provides methods for retrieving the bearer type of the current active network connection. The count of all active connections can be retrieved using RConnectionMonitor::GetConnectionCount(). Then, for each active connection, we can retrieve the connection ID and count of subconnections using RConnectionMonitor::GetConnectionInfo(). Once the connection ID is available we can determine the bearer type using RConnectionMonitor::GetIntAttribute () by passing the attribute KBearer for the desired connection.

Note however that the NetworkControl capability is required to retrieve this information.

Solution

Required Headers & Libraries:

 #include <rconnmon.h> // Link against connmon.lib

Code:

  RConnectionMonitor monitor;
  TRequestStatus status1, status2;
  TInt bearerType( 0 );
  TUint connectionCount( 0 );
  TUint subConnectionCount( 0 );
  TUint connectionId( 0 );
 
  monitor.ConnectL(); // Open RConnectionMonitor object
 
  // Get connection count
  monitor.GetConnectionCount( connectionCount, status1 );
  User::WaitForRequest( status1 );
 
  if ( status1.Int() != KErrNone )
    {
    // Handle errors
    }
  if ( connectionCount == 0 )
    {
    // No connection
    }
 
  // Get connection info of all the active connections
  for ( TUint idx = 1; idx <= iConnectionCount; idx++ )
    {
    // Get the connection id
    TInt error = monitor.GetConnectionInfo( idx, connectionId,
                                             subConnectionCount );
    if ( error != KErrNone )
      {
      // Handle errors
      }
 
    // Retrieve the bearer type - on return, bearerType will 
    // contain one of the values in TConnMonBearerType enumeration
 
    monitor.GetIntAttribute( connectionId, 0, KBearer, bearerType, status2 );
    User::WaitForRequest( status2 );
 
    if ( status2.Int() != KErrNone )
      {
      // Handle errors
      }
    }
 
  monitor.Close(); // Close RConnectionMonitor object
