Abstract

A method, non-transitory computer readable medium and apparatus for detecting a tethering function being performed by an endpoint device in a communications network are disclosed. For example, the method analyzes a data packet directed towards the endpoint device, detects a signature based upon analyzing the data packet, and identifies the endpoint device as performing the tethering function based upon detecting the signature.

Claims (34)

1. A method for detecting a tethering function being performed by an endpoint device in a communications network, comprising:

analyzing, by a processor, a data packet directed towards the endpoint device;

detecting, by the processor, a signature based upon analyzing the data packet wherein the signature indicates the data packet is for a particular operating system and the detecting the signature comprises identifying the data packet as not being compatible with the endpoint device that is associated with a subscription; and

identifying, by the processor, the endpoint device as performing the tethering function based upon detecting the signature.

2. The method of claim 1 , wherein the analyzing comprises examining a header of the data packet.

3. The method of claim 1 , wherein the analyzing comprises examining the data packet for an announcement identifying the operating system that the data packet is intended for.

4. The method of claim 1 , wherein the analyzing comprises examining a source port and a destination port of the data packet.

5. The method of claim 1 , wherein the endpoint device is identified as performing the tethering function when a predetermined number of tethering instances is detected within a predetermined period of time.

6. The method of claim 1 , wherein the endpoint device is a wireless endpoint device associated with the subscription to a service provided by a network service provider of the communications network.

7. The method of claim 1 , further comprising:

when the endpoint device is identified as performing the tethering function, then if determining whether the endpoint device is an authorized tethering endpoint device; and

when the endpoint device is not an authorized tethering endpoint device, then notifying a user of the endpoint device to change to a tethering subscription plan for the endpoint device.

8. A non-transitory computer-readable medium storing a plurality of instructions which, when executed by a processor, cause the processor to perform operations for detecting a tethering function being performed by an endpoint device in a communications network, the operations comprising:

analyzing a data packet directed towards the endpoint device;

detecting a signature based upon analyzing the data packet, wherein the signature indicates the data packet is for a particular operating system and the detecting the signature comprises identifying the data packet as not being compatible with the endpoint device that is associated with a subscription; and

identifying the endpoint device as performing the tethering function based upon detecting the signature.

9. The non-transitory computer-readable medium of claim 8 , wherein the analyzing comprises examining a header of the data packet.

10. The non-transitory computer-readable medium of claim 8 , wherein the analyzing comprises examining the data packet for an announcement identifying the operating system that the data packet is intended for.

11. The non-transitory computer-readable medium of claim 8 , wherein the analyzing comprises examining a source port and a destination port of the data packet.

12. The non-transitory computer-readable medium of claim 8 , wherein the endpoint device is identified as performing the tethering function when a predetermined number of tethering instances is detected within a predetermined period of time.

13. The non-transitory computer-readable medium of claim 8 , wherein the endpoint device is a wireless endpoint device associated with the subscription to a service provided by a network service provider of the communications network.

14. The non-transitory computer-readable medium of claim 8 , further comprising:

when the endpoint device is identified as performing the tethering function, then determining whether the endpoint device is an authorized tethering endpoint device; and

when the endpoint device is not an authorized tethering endpoint device, then notifying a user of the endpoint device to change to a tethering subscription plan for the endpoint device.

15. An apparatus for detecting a tethering function being performed by an endpoint device in a communications network, comprising:

a processor; and

a computer-readable medium storing a plurality of instructions which, when executed by the processor, cause the processor to perform operations, the operations comprising:

analyzing a data packet directed towards the endpoint device;

detecting a signature based upon analyzing the data packet, wherein the signature indicates the data packet is for a particular operating system and the detecting the signature comprises identifying the data packet as not being compatible with the endpoint device that is associated with a subscription; and

identifying the endpoint device as performing the tethering function based upon detecting the signature.

16. The apparatus of claim 15 , wherein the endpoint device is identified as performing the tethering function when a predetermined number of tethering instances is detected within a predetermined period of time.

17. The apparatus of claim 15 , further comprising:

when the endpoint device is identified as performing the tethering function, then determining whether the endpoint device is an authorized tethering endpoint device; and

when the endpoint device is not an authorized tethering endpoint device, then notifying a user of the endpoint device to change to a tethering subscription plan for the endpoint device.
