Reducing fraudulent activity associated with mobile networks

1. An apparatus, comprising:

a network interface operable to receive a communication request over a communication link of a radio access network; and

a processor communicatively coupled to the network interface and operable to:

determine one or more characteristics associated with the communication request, wherein at least one of the characteristics comprises a subscriber identifier and a hardware identifier associated with the communication request;

identify at least one previous communication associated with at least one of the subscriber identifier and the hardware identifier;

determine a call duration of the at least one previous communication;

apply one or more policy rules to the one or more determined characteristics associated with the communication request and the call duration of the at least one previous communication; and

terminate the communication request based in part on the application of the one or more policy rules to the one or more determined characteristics and the call duration of the at least one previous communication.

2. The apparatus of claim 1 , wherein the processor is further operable to determine the one or more policy rules to apply from a set of policy rules based in part on the one or more determined characteristics associated with the communication request.

3. The apparatus of claim 1 , wherein:

the processor is further operable to determine whether at least one of the determined characteristics associated with the communication request is included on an exemption list; and

the network interface is further operable to complete the communication request when the exemption list includes at least one of the determined characteristics associated with the communication request.

4. The apparatus of claim 1 , wherein:

the processor is further operable to:

associate the hardware identifier to the subscriber identifier;

determine a count of hardware identifiers associated with the subscriber identifier; and

when the count of hardware identifiers associated with the subscriber identifier exceeds a hardware identifier threshold, terminate the communication request.

5. The apparatus of claim 4 , wherein the processor is further operable to:

determine a count of subscriber identifiers associated with the hardware identifier; and

when the count of subscriber identifiers associated with the hardware identifier exceeds a subscriber identifier threshold, terminate the communication request.

6. The apparatus of claim 4 , wherein the subscriber identifier is the international mobile subscriber identity (IMSI).

7. The apparatus of claim 4 , wherein the hardware identifier is the international mobile station equipment identity (IMEI).

8. A method, comprising:

receiving a communication request over a communication link of a radio access network;

determining, by a processor, one or more characteristics associated with the communication request, wherein at least one of the characteristics comprises a subscriber identifier and a hardware identifier associated with the communication request;

identifying, by the processor, at least one previous communication associated with at least one of the subscriber identifier and the hardware identifier;

determining, by the processor, a call duration of the at least one previous communication;

applying, by the processor, one or more policy rules to the one or more determined characteristics associated with the communication request and the call duration of the at least one previous communication; and

terminating the communication request based in part on the application of the one or more policy rules to the one or more determined characteristics and the call duration of the at least one previous communication.

9. The method of claim 8 , further comprising determining, by the processor, one or more policy rules to apply from a set of policy rules based in part on the one or more determined characteristics associated with the communication request.

10. The method of claim 8 , further comprising:

determining, by the processor, whether at least one of the determined characteristics associated with the communication request is included on an exemption list; and

completing the communication request when the exemption list includes at least one of the determined characteristics associated with the communication request.

11. The method of claim 8 ,

further comprising:

associating the hardware identifier to the subscriber identifier;

determining, by the processor, a count of hardware identifiers associated with the subscriber identifier; and

when the count of hardware identifiers associated with the subscriber identifier exceeds a hardware identifier threshold, terminating the communication request.

12. The method of claim 11 , further comprising:

determining, by the processor, a count of subscriber identifiers associated with the hardware identifier; and

when the count of subscriber identifiers associated with the hardware identifier exceeds a subscriber identifier threshold, terminating the communication request.

13. The method of claim 11 , wherein the subscriber identifier is the international mobile subscriber identity (IMSI).

14. The method of claim 11 , wherein the hardware identifier is the international mobile station equipment identity (IMEI).

15. Non-transitory computer readable medium comprising logic, the logic, when executed by a processor, operable to:

receive a communication request over a communication link of a radio access network; and

determine one or more characteristics associated with the communication request, wherein at least one of the characteristics comprises a subscriber identifier and a hardware identifier associated with the communication request;

identify at least one previous communication associated with at least one of the subscriber identifier and the hardware identifier;

determine a call duration of the at least one previous communication;

apply one or more policy rules to the one or more determined characteristics associated with the communication request, and the call duration of the at least one previous communication; and

terminate the communication request based in part on the application of the one or more policy rules to the one or more determined characteristics and the call duration of the at least one previous communication.

16. The computer readable medium of claim 15 , wherein the logic is further operable to determine one or more policy rules to apply from a set of policy rules based in part on the one or more determined characteristics associated with the communication request.

17. The computer readable medium of claim 15 , wherein the logic is further operable to:

determine whether at least one of the determined characteristics associated with the communication request is included on an exemption list; and

complete the communication request when the exemption list includes at least one of the determined characteristics associated with the communication request.

18. The computer readable medium of claim 15 , wherein

the logic is further operable to:

associate the hardware identifier to the subscriber identifier;

determine a count of hardware identifiers associated with the subscriber identifier; and

when the count of hardware identifiers associated with the subscriber identifier exceeds a hardware identifier threshold, terminate the communication request.

19. The computer readable medium of claim 15 , wherein the logic is further operable to:

determine a count of subscriber identifiers associated with the hardware identifier; and

when the count of subscriber identifiers associated with the hardware identifier exceeds a subscriber identifier threshold, terminate the communication request.

20. The computer readable medium of claim 15 , wherein the subscriber identifier is the international mobile subscriber identity (IMSI).
