Modifying wireless network paging zone broadcast based on wireless access congestion

1. A method of operating a wireless access control system, comprising:

monitoring a first wireless access node to determine when the first wireless access node experiences wireless access congestion, wherein the first wireless access node broadcasts a first paging zone identifier for first paging zone for receipt by wireless communication devices receiving wireless access from the first wireless access node;

in response to the wireless access congestion at the first wireless access node, instructing a second wireless access node which broadcasts a second paging zone identifier for second paging zone to toggle between broadcasting the first paging zone identifier for first paging zone and broadcasting the second paging zone identifier for second paging zone at a first duty cycle.

2. The method of claim 1 , wherein the first wireless access node is located across a paging zone boundary from the second wireless access node, wherein the paging zone boundary comprises a boundary between a first paging zone associated with the first paging zone identifier and a second paging zone associated with the second paging zone identifier.

3. The method of claim 2 , wherein the first wireless access node experiences wireless access congestion when a direction of travel of the wireless communication devices receiving the wireless access from the first wireless access node indicates travel across the paging zone boundary.

4. The method of claim 1 , wherein the first wireless access node experiences wireless access congestion when access channel utilization of the first wireless access node exceeds a utilization threshold.

5. The method of claim 1 , wherein the first wireless access node experiences wireless access congestion when a predetermined time of day occurs.

6. The method of claim 1 , wherein the first wireless access node experiences wireless access congestion when a predetermined amount of wireless communication devices are within a coverage area of the first wireless access node.

7. The method of claim 1 , wherein the first wireless access node experiences wireless access congestion when a congestion history of the first wireless access node indicates a present congestion event for the first wireless access node.

8. The method of claim 1 , wherein the first wireless access node and the second wireless access node are located along a roadway carrying vehicle traffic, and wherein the first duty cycle corresponds to an average speed of the vehicle traffic along the roadway.

9. The method of claim 1 , wherein the first wireless access node and the second wireless access node are located along a roadway carrying vehicle traffic, and wherein the first duty cycle corresponds to a volume level of the vehicle traffic along the roadway.

10. The method of claim 1 , wherein the first duty cycle comprises a 50% duty cycle.

11. A wireless access control system, comprising:

a processing system configured to monitor a first wireless access node to determine when the first wireless access node experiences wireless access congestion, wherein the first wireless access node broadcasts a first paging zone identifier for first paging zone for receipt by wireless communication devices receiving wireless access from the first wireless access node;

in response to the wireless access congestion at the first wireless access node, a control interface configured to instruct a second wireless access node which broadcasts a second paging zone identifier for second paging zone to toggle between broadcasting the first paging zone identifier for first paging zone and broadcasting the second paging zone identifier for second paging zone at a first duty cycle.

12. The wireless access control system of claim 11 , wherein the first wireless access node is located across a paging zone boundary from the second wireless access node, wherein the paging zone boundary comprises a boundary between a first paging zone associated with the first paging zone identifier and a second paging zone associated with the second paging zone identifier.

13. The wireless access control system of claim 12 , wherein the first wireless access node experiences wireless access congestion when a direction of travel of the wireless communication devices receiving the wireless access from the first wireless access node indicates travel across the paging zone boundary.

14. The wireless access control system of claim 11 , wherein the first wireless access node experiences wireless access congestion when access channel utilization of the first wireless access node exceeds a utilization threshold.

15. The wireless access control system of claim 11 , wherein the first wireless access node experiences wireless access congestion when a predetermined time of day occurs.

16. The wireless access control system of claim 11 , wherein the first wireless access node experiences wireless access congestion when a predetermined amount of wireless communication devices are within a coverage area of the first wireless access node.

17. The wireless access control system of claim 11 , wherein the first wireless access node experiences wireless access congestion when a congestion history of the first wireless access node indicates a present congestion event for the first wireless access node.

18. The wireless access control system of claim 11 , wherein the first wireless access node and the second wireless access node are located along a roadway carrying vehicle traffic, and wherein the first duty cycle corresponds to an average speed of the vehicle traffic along the roadway.

19. The wireless access control system of claim 11 , wherein the first wireless access node and the second wireless access node are located along a roadway carrying vehicle traffic, and wherein the first duty cycle corresponds to a volume level of the vehicle traffic along the roadway.

20. The wireless access control system of claim 11 , wherein the first duty cycle comprises a 50% duty cycle.
