Abstract

A method for increasing performance of a wireless communication system is provided. The method includes determining (220) quality of service parameters that will result in a reduced likelihood that an application assigned the determined quality of service parameters will be scheduled for transmission, identifying (230) an application to be provided service that is less than best effort, and assigning (240) the determined one or more quality of service parameters to the identified application. In an embodiment, the method further assigns (250) a dedicated bearer to the identified application and either does not schedule (260) the dedicated bearer at all or schedules (270) the dedicated bearer less frequently compared to a frequency of scheduling a default bearer.

Claims

1. A method to increase performance of a wireless communication system, the method comprising:

determining one or more quality of service parameters that will result in a reduced likelihood that an application assigned the one or more quality of service parameters will be scheduled for transmission;

identifying an application to be provided service that is less than best effort; and

assigning the determined one or more quality of service parameters to the identified application.

2. The method of claim 1, wherein the dedicated bearer is at least one of an Evolved Packet System (EPS) bearer and a WiMAX bearer.

3. The method of claim 1, wherein assigning the determined one or more quality of service parameters comprises assigning a dedicated bearer to the identified application.

4. The method of claim 3, further comprising, subsequent to assigning the dedicated bearer to the identified application, not scheduling the dedicated bearer.

5. The method of claim 3, further comprising, subsequent to assigning the dedicated bearer to the identified application, less frequently scheduling the dedicated bearer compared to a frequency of scheduling a default bearer.

6. The method of claim 3 wherein the identified application is associated with a mobile station, and wherein assigning a dedicated bearer to the identified application comprises assigning the dedicated bearer to the mobile station.

7. The method of claim 1, wherein assigning the dedicated bearer to the mobile station comprises:

allocating, by a network element, the dedicated bearer for applications that are to be provided service that is less than best effort; and

instructing a mobile station, by the network element, to use the allocated dedicated bearer for applications that are to be provided service that is less than best effort.

8. The method of claim 7, wherein assigning the dedicated bearer to the mobile station comprises:

allocating, by the network element, the dedicated bearer for applications that are to be provided service that is less than best effort;

informing the mobile station of the dedicated bearer; and

assigning, by the mobile station, the dedicated bearer for the identified application.

9. The method of claim 1, wherein assigning the determined one or more quality of service parameters comprises sending a policy to a mobile station and wherein the policy informs the mobile station to discard packets related to the identified application

10. The method of claim 1, wherein assigning the determined one or more quality of service parameters comprises requesting a network element to assign a dedicated bearer to the identified application.

12. The method of claim 1, wherein assigning the determined one or more quality of service parameters comprises discarding packets related to the identified application.

13. The method of claim 1, wherein the identified application comprises one or more of a background task, a noisy application, malware, or an over-the-top application.

11. The method of 1, further comprising:

assigning the dedicated bearer, by the network element, to the identified application;

scheduling the dedicated bearer; and

scheduling a default bearer, wherein the scheduling of the dedicated bearer is less frequently than the scheduling of the default bearer.

14. An apparatus comprising:

a network element having a processor that is configured to determine one or more quality of service parameters that will result in a reduced likelihood that an application assigned the one or more quality of service parameters will be scheduled for transmission, identify an application to be provided service that is less than best effort and assign the determined one or more quality of service parameters to the identified application.

15. The apparatus of claim 14, wherein the processor further is configured to assign a dedicated bearer to the identified application.

16. The apparatus of claim 15, wherein the identified application is associated with a mobile station.

17. The apparatus of claim 15, wherein the processor is configured to, subsequent to assigning the dedicated bearer to the identified application, not schedule the dedicated bearer.

18. The apparatus of claim 15, wherein the processor is configured to schedule the dedicated bearer and schedule a default bearer wherein, subsequent to assigning the dedicated bearer to the identified application, the scheduling of the dedicated bearer is less frequent than the scheduling of the default bearer.

19. The apparatus of claim 14, wherein the processor is configured to sends a policy to a mobile station, wherein the policy informs the mobile station to discard packets related to the identified application.

20. The apparatus of claim 19, wherein the network element comprises one or more of a base station, an Access Service Network—

Gateway, a policy manager, and a packet flow optimizer.

21. An apparatus for scheduling bearer traffic comprising:

a mobile station having a processor that is configured to determine one or more quality of service parameters that will result in a reduced likelihood that an application assigned the one or more quality of service parameters will be scheduled for transmission, identify an application to be provided service that is less than best effort, and assign the determined one or more quality of service parameters to the identified application.

22. The system of claim 21, wherein the apparatus further comprises a network element and wherein the network element is configured to assign the dedicated bearer to the identified application and does not schedule the dedicated bearer.

23. The apparatus of claim 21, wherein the apparatus further comprises a network element and wherein the network element is configured to assign the dedicated bearer to the identified application, schedule the dedicated bearer, and schedule a default bearer, wherein, subsequent to assigning the dedicated bearer, the scheduling of the dedicated bearer is less frequent than the scheduling of the default bearer.

24. The apparatus of claim 21, wherein the mobile station processor is configured to discard packets related to the identified application.
