Steps:
1. Download nusoap library from internet.
2. Pass parameter list in your $client->call and enjoy.

getError();
if ($err) {
  // Display the error
  echo '
Constructor error: ' . $err . '
';
  // At this point, you know the call that follows will fail
}

// update_location method parameter
$param = array(
    'device_number'   => '9910948357',
    'latitude'     => '40.727757',
    'longitude'     => '-73.984366',
    'battery_status'  => '30'
  );
// user_action method parameter
$param2 = array(
    'device_number'   => '27ab2026da5213ebd6c95e5fbe50965bdfaddf4b',
    'latitude'     => '40.727757',
    'longitude'     => '-73.984366',
    'user_action'    => 'Meeting_Test'
  );
// sos method parameter
$param3 = array(
    'device_number'   => '9910948357',
    'latitude'     => '40.727757',
    'longitude'     => '-73.984366',
  );
//$result = $client->call('update_location', $param);
//$result = $client->call('user_action', $param2);
//$result = $client->call('sos', $param3);
$result = $client->call('user_entity_status', array('device_number' => '27ab2026da5213ebd6c95e5fbe50965bdfaddf4b'));
////////////////////////////////////////////////////////
////////////////////////////////////////////////////////
// Check for a fault
if ($client->fault) {
  echo '
Fault: ';
  print_r($result);
  echo '
';
} else {
  // Check for errors
  $err = $client->getError();
  if ($err) {
    // Display the error
    echo '
Error: ' . $err . '
';
  } else {
    // Display the result
    echo "
";
    print_r($result);
    echo "
";
  }
}
echo '
Request
';
echo '
' . htmlspecialchars($client->request, ENT_QUOTES) . '
';
echo '
Response
';
echo '
' . htmlspecialchars($client->response, ENT_QUOTES) . '
';
/*
// Display the debug messages
echo '
Debug
';
echo '
' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '
';
*/
?>
