You can use something like:
e.g
bottom frame name = BOTO and the top frame name is TOPO
put this script in the bottom frame:
########################################
<script>
function reload_top_frame(){
parent.TOPO.document.location.reload()
}
</script>
<a href="javascript:reload_top_frame()">Reload the Main Window</a>
##########################################
