Abstract

Maps of high wireless device movement and high wireless device traffic are created. These maps are correlated over selected periods of time to determine when, and where, large numbers of wireless devices are both moving and creating problematic traffic. Stationary wireless devices using an access node in the problem area are identified before the selected time period (e.g., 30 minutes before commuting time). These stationary wireless devices are handed over to a reserved frequency band. During the selected time period, wireless devices requesting access in the problem area are denied access using the reserved frequency band and are instead forced to use another frequency band.

First claim

What is claimed is:

1. A method of operating a communication system, comprising:
correlating a first plurality of traffic volume indicators with a first plurality of mobility indicators, the first plurality of traffic volume indicators and the first plurality of mobility indicators associated with an access node and a reoccurring time period;
based on the correlation between the first plurality of traffic volume indicators and the first plurality of mobility indicators over the reoccurring time period, selecting the access node for load balancing;
prior to the reoccurring time period, determining a set of stationary wireless devices being served by the access node; and,
during the reoccurring time period, controlling the access node to serve the set of stationary wireless devices using a first frequency band.

2. The method of claim 1 , further comprising:
during the reoccurring time period, controlling the access node to serve devices requesting access via the access node using at least one frequency band that is not the first frequency band.

3. The method of claim 1 , further comprising:
during the reoccurring time period, denying requests by wireless devices being handed off to the access node to be serviced using the first frequency band.

4. The method of claim 3 , further comprising:
during the reoccurring time period, accepting requests by the wireless devices being handed off to the access node to be serviced using a second frequency band.

5. The method of claim 1 , wherein the recurring time period is based on a second correlation of a second plurality of traffic volume indicators with a second plurality of mobility indicators.

6. The method of claim 5 , wherein the second plurality of mobility indicators are based on handoffs between neighboring access nodes and the access node.

7. The method of claim 5 , wherein second plurality of traffic volume indicators are based on air-interface resources used by the access node.

8. The method of claim 5 , wherein second plurality of traffic volume indicators are based on data quantities transferred by the access node.

9. The method of claim 5 , wherein the second plurality of mobility indicators are based on cell reselections associated with the access node.

10. A communication system, comprising:
an processing node configured to:
correlate a first plurality of traffic volume indicators with a first plurality of mobility indicators, the first plurality of traffic volume indicators and the first plurality of mobility indicators associated with an access node and a reoccurring time period;
based on the correlation between the first plurality of traffic volume indicators and the first plurality of mobility indicators over the reoccurring time period, select the access node for load balancing;
prior to the reoccurring time period, determine a set of stationary wireless devices being served by the access node; and
during the reoccurring time period, control the access node to serve the set of stationary wireless devices using a first frequency band.

11. The system of claim 10 , wherein the processing node is further configured to:
during the reoccurring time period, control the access node to serve devices requesting access via the access node using at least one frequency band that is not the first frequency band.

12. The system of claim 10 , wherein the processing node is further configured to:
during the reoccurring time period, deny requests by wireless devices being handed off to the access node to be serviced using the first frequency band.

13. The system of claim 12 , wherein the processing node is further configured to:
during the reoccurring time period, accept requests by the wireless devices being handed off to the access node to be serviced using a second frequency band.

14. The system of claim 10 , wherein the reoccurring time period is based on a second correlation of a second plurality of traffic volume indicators with a second plurality of mobility indicators.

15. The system of claim 14 , wherein the second plurality of mobility indicators are based on handoffs between neighboring access nodes and the access node.

16. The system of claim 14 , wherein the second plurality of traffic volume indicators are based on air-interface resources used by the access node.

17. The system of claim 14 , wherein the second plurality of traffic volume indicators are based on data quantities transferred by the access node.

18. The system of claim 14 , wherein the second plurality of mobility indicators are based on cell reselections associated with the access node.
