Abstract

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for providing on-demand quality of service guarantees in a wireless network environment. The system determines an on-demand quality of service for a segment of a communication path between a user equipment communicating with a radio access network connected to a core network and an external network connected to the core network. The system then determines if the on-demand quality of service for the segment meets a quality of service requirement. If the on-demand quality of service for the segment does not meet the quality of service requirement, the system identifies an alternate communication path between the user equipment and the external network, wherein the alternate communication path differs from the communication path. The system can then setup the alternate communication path for traffic between the user equipment and the external network.

First claim

We claim:

1. A method comprising:
determining, via a processor, a quality of service for a segment of a communication path between a user equipment communicating through a radio access network to a destination equipment; and
when the quality of service does not meet a quality of service requirement, identifying an end to end alternative communication path between the user equipment and the destination equipment, wherein the end to end alternative communication path differs from the communication path by connecting to the destination equipment without communicating via the radio access network.

2. The method of claim 1 , wherein the radio access network is an evolved universal mobile telecommunications system terrestrial radio access network.

3. The method of claim 2 , wherein the end to end alternative communication path comprises one of the Internet, a local area network, a wide area network, and a virtual network.

4. The method of claim 1 , wherein the end to end alternative communication path utilizes a wireless local area network.

5. The method of claim 1 , further comprising establishing the end to end alternate communication path between the user equipment and an external network.

6. The method of claim 5 , wherein the establishing of the end to end alternative communication path is coordinated by a mobile management entity.

7. The method of claim 1 , wherein the quality of service is associated with one of a bandwidth, a delay, a signal power, a packet loss, an amount of jitter, and a bit rate.

8. The method of claim 1 , wherein the quality of service requirement comprises pre-defined quality of service parameters associated with an application.

9. The method of claim 1 , wherein determining of the quality of service for the segment comprises detecting an on-demand application quality of service need associated with the user equipment.

10. A system comprising:
a processor; and
a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising:
determining, via a processor, a quality of service for a segment of a communication path between a user equipment communicating through a radio access network to a destination equipment; and
when the quality of service does not meet a quality of service requirement, identifying an end to end alternative communication path between the user equipment and the destination equipment, wherein the end to end alternative communication path differs from the communication path by connecting to the destination equipment without communicating via the radio access network.

11. The system of claim 10 , wherein the radio access network is an evolved universal mobile telecommunications system terrestrial radio access network.

12. The system of claim 11 , wherein the end to end alternative communication path comprises one of the Internet, a local area network, a wide area network, and a virtual network.

13. The system of claim 10 , wherein the end to end alternative communication path utilizes a wireless local area network.

14. The system of claim 10 , the computer-readable storage medium having additional instructions stored which, when executed by the processor, result in operations comprising establishing the end to end alternate communication path between the user equipment and an external network.

15. The system of claim 14 , wherein the establishing of the end to end alternative communication path is coordinated by a mobile management entity.

16. The system of claim 10 , wherein the quality of service is associated with one of a bandwidth, a delay, a signal power, a packet loss, an amount of jitter, and a bit rate.

17. The system of claim 10 , wherein the quality of service requirement comprises pre-defined quality of service parameters associated with an application.

18. The system of claim 10 , wherein determining of the quality of service for the segment comprises detecting an on-demand application quality of service need associated with the user equipment.

19. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:
determining, via a processor, a quality of service for a segment of a communication path between a user equipment communicating through a radio access network to a destination equipment; and
when the quality of service does not meet a quality of service requirement, identifying an end to end alternative communication path between the user equipment and the destination equipment, wherein the end to end alternative communication path differs from the communication path by connecting to the destination equipment without communicating via the radio access network.

20. The computer-readable storage device of claim 19 , wherein the radio access network is an evolved universal mobile telecommunications system terrestrial radio access network.
