Abstract

Managing data resource utilization in a wireless network environment comprising a first data network and a second data network is described herein. The described management infrastructure and method incorporates monitoring data usage of a wireless network subscriber over the first data network, determining that the data usage over the first data network meets a specified threshold, and, in response to the determination that usage has reached the specified threshold, administratively disconnecting the wireless network subscriber from the first data network so as to cause a data session of the wireless network subscriber to be reassigned to the second data network.

Claims

1. A method for managing data resource utilization in a wireless network environment comprising a first data network and a second data network, the method comprising:

monitoring data usage over the first data network;

determining that the data usage over the first data network satisfies a specified criterion; and

in response to the determining step, administratively disconnecting a wireless network subscriber from the first data network so as to cause a subsequent data session of the wireless network subscriber to be reassigned to the second data network.

2. The method of claim 1 wherein the data usage over the first data network measured during the monitoring step is data usage by the wireless network subscriber.

3. The method of claim 2 wherein the specified criterion comprises reaching a specified maximum usage threshold by the wireless network subscriber.

4. The method of claim 3 wherein the maximum usage threshold is associated with a specified duration.

5. The method of claim 4 wherein the wireless network subscriber is prevented from establishing a session on the first data network for a remainder of the specified duration.

6. The method of claim 2 wherein the first data network is configured to support a higher data throughput per user session than a throughput supported on a per user session on the second data network.

7. The method of claim 2 wherein administratively disconnecting the wireless network subscriber from the first data network comprises triggering a resource reclaim message.

8. The method of claim 2 wherein, as a consequence of administratively disconnecting the wireless network subscriber, further steps are performed for:

clearing cached information on the data session from a plurality of network elements, and

updating a user profile associated with the wireless network subscriber to deny user device authentication on the first data network.

9. The method of claim 8 wherein the plurality of network elements comprises at least one of a Radio Network Controller (RNC) and a Packet Data Serving Node (PDSN).

10. The method of claim 8 wherein after the user device is denied authentication on the first data network, further steps are performed to automatically route a request to initiate a data session to the second data network.

11. The method of claim 6 further comprising:

denying, in accordance with the administratively disconnecting, the user device authentication on the first data network, and

directing, after the denying step, a request to initiate a data session by the user device to the second data network.

12. A system for managing data resource utilization in a wireless network environment, the system comprising:

a first data network;

a second data network communicatively coupled to the first data network in the wireless network environment; and

a rating engine configured to monitor data usage over the first data network and, upon determining that the data usage over the first data network satisfies a specified criterion, cause a wireless network subscriber to be administratively disconnected from the first data network so as to further cause a subsequent data session of the wireless network subscriber to be reassigned to the second data network.

13. The system of claim 12 wherein the data usage over the first data network monitored by the rating engine is data usage by the wireless network subscriber.

14. The system of claim 13 wherein the specified criterion comprises reaching a predetermined maximum usage threshold by the wireless network subscriber.

15. The system of claim 14 wherein the maximum usage threshold is associated with a specified duration.

16. The system of claim 15 wherein the wireless network subscriber is prevented from establishing a session on the first data network for a remainder of the specified duration.

17. The system of claim 13 wherein the first data network is configured to support a higher data throughput per user session than a throughput supported on a per user session on the second data network.

18. The system of claim 13 wherein the rating engine causes the wireless network subscriber to be administratively disconnected from the first data network by causing an Operation and Support System (OSS) to trigger a resource reclaim message.

19. The system of claim 13 wherein, as a consequence of the administrative disconnection of the wireless network subscriber, the rating engine causes the Operation and Support System (OSS) to clear cached information on the data session from a plurality of network elements and to update a user profile associated with the wireless network subscriber to deny user device authentication on the first data network.

20. The system of claim 19 wherein the plurality of network elements comprises at least one of a Radio Network Controller (RNC) and a Packet Data Serving Node (PDSN).
