Abstract
Cellular communication systems supporting high utilization geographic regions having extensive cell overlap segments that collectively contain a substantial portion of the mobile units. A system and method for channel assignments incorporating selection from alternative transceivers defining overlapping cells is provided with load balancing to reduce call blocking. The system incorporates selective multiple handoffs responsive to channel assignment requests both to extend load balancing and also to substantially avoid call cutoff when active mobile units cross cell boundaries into possibly saturated cells.
