Abstract

Examples disclosed herein provide systems, methods, and software for providing data quotas based a quota query load. In one example, a method of operating a communication system includes transferring a quota request for a wireless communication device from a packet data network gateway to an online charging server. The method further includes, in the online charging server, receiving the request, identifying a data quota based on a quota query load, and transferring the data quota to the packet data network gateway to be implemented for the wireless communication device.

Claims

1. A method of operating a communication system to provide dynamic data quotas for wireless communication devices, the method comprising:

in a packet data network gateway, identifying a communication request for a wireless communication device and, responsive to the communication request, transferring a quota request for the wireless communication device to an online charging server;

in the online charging server, in response to receiving the quota request, identifying a data quota size for a data quota to be supplied for the wireless communication device based on a quota query load, wherein the quota query load comprises a number of quota requests received from at least one packet data network gateway by the online charging server over a period of time, and transferring the data quota to the packet data network gateway; and

in the packet data network gateway, receiving the data quota for the wireless communication device.

2. The method of claim 1 wherein the data quota comprises a portion of total data available to the wireless communication device for a time period.

3. The method of claim 1 wherein identifying the data quota size for the data quota to be supplied for the wireless communication device based on the quota query load comprises identifying the data quota size for the data quota to be supplied for the wireless communication device in proportion to the quota query load.

4. The method of claim 3 further comprising identifying an availability time period for the data quota in proportion to the quota query load.

5. The method of claim 1 further comprising:

in the packet data network gateway and responsive to exhausting the data quota, transferring a subsequent quota request for the wireless communication device to the online charging server;

in the online charging server, receiving the subsequent quota request, identifying a second data quota size for a subsequent data quota to be supplied for the wireless communication device based on the quota query load, and transferring the subsequent data quota to the packet data network gateway; and

in the packet data network gateway, receiving the subsequent data quota for the wireless communication device.

6. The method of claim 5 wherein the data quota and the subsequent data quota comprise different data quotas.

7. The method of claim 1 further comprising, in the online charging server, identifying an availability time period for the data quota based on the quota query load.

8. A system for providing dynamic data quotas, the system comprising:

a packet data network gateway configured to;

identify a communication request for a wireless communication device;

responsive to the communication request, transfer a quota request for the wireless communication device to an online charging server; and

receive a data quota for the wireless communication device from the online charging server; and

the online charging server configured to;

receive the quota request;

in response to receiving the quota request, identify a data quota size for the data quota to be supplied for the wireless communication device based on a quota query load, wherein the quota query load comprises a number of quota requests received from at least one packet data network gateway by the online charging server over a segment of time; and

transfer the data quota to the packet data network gateway.

9. The system of claim 8 wherein the data quota comprises a portion of total data available to the wireless communication device for a time period.

10. The system of claim 9 wherein the online charging server configured to identify the data quota size for the data quota to be supplied for the wireless communication device based on the quota query load is configured to identify the data quota size for the data quota to be supplied for the wireless communication device in proportion to the quota query load.

11. The system of claim 10 wherein the online charging server is further configured to identify an availability time period for the data quota in proportion to the quota query load.

12. The system of claim 8 wherein the packet data network gateway configured to transfer the quota request for the wireless communication device to the online charging server is configured to transfer the quota request for the wireless communication device to the online charging server using a Gy interface.

13. The system of claim 8 wherein the online charging server is further configured to identify an availability time period for the data quota based on the quota query load.

14. A method of operating an online charging server to provide dynamic data quotas comprising:

identifying a quota query load, wherein the quota query load comprises a number of quota requests received from at least one packet data network gateway by the online charging server over a segment of time;

for a given quota request received from a packet data network gateway to support a communication for a wireless communication device, identifying a data quota size for a data quota to be supplied for the communication based on the quota query load; and

transferring the data quota to the packet data network gateway.

15. The method of claim 14 wherein the data quota comprises a portion of total data available to a wireless communication device for a period of time.

16. The method of claim 14 wherein identifying the data quota size for the data quota to be supplied for the communication based on the quota query load comprises identifying the data quota size for the data quota to be supplied for the communication in proportion to the quota query load.

17. The method of claim 16 further comprising:

identifying an availability time period for the data quota in proportion to the quota query load.

18. The method of claim 14 further comprising:

for a second quota request received from the packet data network gateway to support a second communication for a second wireless communication device, identifying a second data quota size for a second data quota to be supplied for the second communication based on the quota query load; and

transferring the second data quota to the packet data network gateway.

19. The method of claim 14 further comprising identifying an availability time period for the data quota based on the quota query load.
