A page routing system comprises a communication transceiver and a processing system, wherein a wireless communication network comprises a plurality of paging zones and each of the paging zones comprises a plurality of sectors. The communication transceiver is configured to transmit pages to the paging zones for delivery to wireless communication devices located in the sectors and to receive page responses from the paging zones that were transferred by the wireless communication devices located in the sectors. The processing system is configured to determine page utilization for each of the paging zones, to track the page responses per-sector for each of the wireless communication devices, to receive a new page for one of the wireless communication devices in one of the paging zones, and if the page utilization for the one paging zone exceeds a zone threshold, then to select a target one of the sectors in the one paging zone for page delivery based on the page responses per-sector for the one wireless communication device.
