Same pagination Posts feeds

Hi.
I’m trying to add some pagination stuff on a couple of posts belongs to my category and others that belongs to an rss feed.
The code is the following:

query_posts('cat=27');
$rss = fetch_feed('......my feed...');
if (!is_wp_error( $rss ) ) :
	$maxNr = 15;
	$maxitems = $rss->get_item_quantity($maxNr);
	$rss_items = $rss->get_items(0, $maxitems);
endif;
if ($maxitems == 0) echo '<li>No items.</li>';
	 else
       foreach ( $rss_items as $item ) : ?>
<article class="feed_article"> <?php $content = str_replace("http://www.facebook.com/l.php?u=","",$item->get_description());
$content = str_replace("%2F","/",$content);
$content = str_replace("%3A",":",$content);
preg_match_all('#\bhttps?://[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/))#', $content, $match);
foreach($match[0] as $itemvalue ) {
$newlink = str_replace($itemvalue2,"",$itemvalue);		$content =str_replace($itemvalue,$newlink,$content);
echo $content;						?>									</article>
	<?php endforeach; ?>
if ( have_posts() ) :
while ( have_posts() ) : the_post();
//...... design stuff
endwhile;
<?php wp_pagenavi(); ?>

The result is (of course) reading all my articles from Rss specified but without pagination followed by a normal pagination put it to specified posts.How can make a “union” between the posts from RSS and posts from category under same pagination?

Thanks a lot,

Iulian,
