Abstract

The subject matter described herein includes methods, systems, and computer readable media for network metadata based policy control. According to one aspect, a system for network metadata based policy control is provided. The system includes a network metadata directed policy server for obtaining network information for a plurality of subscribers, for deriving network metadata from the network information, for applying a network metadata policy manipulation rule for changing a value of a network an operator assigned policy control parameter for the subscribers, and for generating an instruction for changing the value of the network operator assigned policy control parameter for the subscriber. The system further includes a policy control and charging rules function (PCRF) node for detecting the instruction and for instructing a policy and charging enforcement function (PCEF) node to change value of the operator assigned policy control parameter for the subscribers.

Claims

1. A system for network metadata based policy control, the system comprising:

a policy store for storing at least one network metadata policy manipulation rule for triggering a change in a value of an operator assigned policy control parameter for subscribers; and

a network metadata directed policy server for obtaining network information for a plurality of subscribers, for deriving network metadata from the network information, wherein the network metadata includes a number of a service provider'"'"'s subscribers that are present in a single retailer location or across plural retailer locations, for accessing the policy store and applying one of the network metadata policy manipulation rules for changing a value of an operator assigned policy control parameter for the subscribers, for determining whether a threshold condition specified by the applied network metadata policy manipulation rule is satisfied, and for generating an instruction to automatically trigger the change in the value of the network operator assigned policy control parameter for currently active sessions of an identified group of a plurality of subscribers determined to be present in the single retailer location or across plural retailer locations to a new value in response to determining that the threshold condition is satisfied.

2. The system of claim 1 comprising a policy and charging rules function (PCRF) node for detecting the instruction and for instructing a policy and charging enforcement function (PCEF) node to change the value of the operator assigned policy control parameter for the identified group of subscribers.

3. The system of claim 1 wherein the network metadata directed policy server is configured to instruct a policy and charging enforcement function (PCEF) node to change the value of the operator assigned policy control parameter for the identified group of subscribers.

4. The system of claim 1 wherein the network information identifies geographic locations of a service provider'"'"'s subscribers.

5. The system of claim 1 wherein the network metadata policy manipulation rule is based on an agreement between a wireless network operator and a retailer.

6. The system of claim 1 wherein the instruction identifies individual subscribers within the group to which the network policy manipulation rule is to be applied.

7. The system of claim 2 wherein the instruction identifies a geographic area to which the network metadata policy manipulation rule is to be applied and wherein the PCRF node identifies individual subscribers within the group determined to be present in the geographic area to which the network metadata policy manipulation rule is to be applied.

8. The system of claim 1 wherein the network metadata policy manipulation rule identifies the group of subscribers at a plurality of different retailer locations whose download bandwidth is to be temporarily enhanced.

9. The system of claim 2 wherein the network metadata policy manipulation rule identifies a plurality of retailer locations where download bandwidth is to be temporarily enhanced and wherein the PCRF node is configured to identify individual subscribers within the group of subscribers determined to be present at the retailer locations whose download bandwidths are to be temporarily enhanced.

10. The system of claim 1 wherein the network operator assigned policy control parameter comprises a download bandwidth parameter.

11. The system of claim 1 wherein the network metadata directed policy server defines a time period during which the value of the network operator assigned policy control parameter will be changed.

12. The system of claim 2 wherein the network metadata directed policy server or the PCRF node generates an accounting record upon changing the value of the network operator assigned policy control parameter to the new value.

13. The system of claim 1 wherein the network metadata directed policy server is configured to obtain the network information from a home subscriber server, a location server, a presence server, or mobile handsets.

14. The system of claim 1 comprising a Diameter signaling router (DSR) configured to intercept update location messages regarding the subscribers and to provide corresponding subscriber information to the network metadata directed policy server.

15. The system of claim 1 comprising a policy and charging rules function (PCRF) node, wherein the network metadata directed policy server and the policy store are components of the PCRF node.

16. A method for network metadata based policy control, the method comprising:

at a network metadata directed policy server;

obtaining network information for a plurality of subscribers;

deriving network metadata from the network information, wherein the network metadata includes a number of a service provider'"'"'s subscribers that are present in a single retailer location or across plural retailer locations;

applying a network metadata policy manipulation rule for triggering a change in a value of an operator assigned policy control parameter for the subscribers;

determining whether a threshold condition specified by the applied network metadata policy manipulation rule is satisfied; and

generating an instruction for automatically triggering the change in the value of the network operator assigned policy control parameter for currently active sessions of an identified group of a plurality of subscribers determined to be present in the single retailer location or across plural retail locations to a new value in response to determining that the threshold condition is satisfied.

17. The method of claim 16 comprising, at a policy and charging rules function (PCRF) node, detecting the instruction and instructing a policy and charging enforcement function (PCEF) node to change the value of the operator assigned policy control parameter for the identified group of subscribers.

18. The method of claim 16 comprising, at the network metadata directed policy server, instructing a policy and charging enforcement function (PCEF) node to change the value of the operator assigned policy control parameter for the identified group of subscribers.

19. The method of claim 16 wherein the network information identifies geographic locations of a service provider'"'"'s subscribers.

20. The method of claim 16 wherein the network metadata policy manipulation rule is based on an agreement between a wireless network operator and a retailer.

21. The method of claim 16 wherein the instruction identifies individual subscribers within the group to which the network policy manipulation rule is to be applied.

22. The method of claim 17 wherein the instruction identifies a geographic area to which the network metadata policy manipulation rule is to be applied and wherein the PCRF node identifies individual subscribers within the group determined to be present in the geographic area to which the network metadata policy manipulation rule is to be applied.

23. The method of claim 16 wherein the network metadata policy manipulation rule identifies subscribers within the group of subscribers present at a plurality of different retailer locations whose download bandwidth is to be temporarily enhanced.

24. The method of claim 17 wherein the network metadata policy manipulation rule identifies a plurality of retailer locations where download bandwidth is to be temporarily enhance and wherein the PCRF node is configured to identify individual subscribers within the group of subscribers present at the retailer locations whose download bandwidths are to be temporarily enhanced.

25. The method of claim 16 wherein the network operator assigned policy control parameter comprises a download bandwidth parameter.

26. The method of claim 16 wherein the network metadata directed policy server defines a time period during which the value of the network operator assigned policy control parameter will be changed.
