Abstract

A system for enforcing quality of service and methods of configuring and enforcing quality of service (QoS). In one embodiment, the system includes: (1) a host configured to process a plurality of applications and (2) a modem coupled to the host and configured to interface with data networks and having a non-access stratum configured to prioritize real time data packets and selectively to discard data packets based on a defined criteria.

Claims

1. A system for enforcing quality of service, comprising:

a host configured to process a plurality of applications; and

a modem coupled to said host and configured to interface with data networks and having a non-access stratum configured to prioritize real time data packets and selectively to discard data packets based on a defined criteria.

2. The system as recited in claim 1 wherein said plurality of applications further comprises:

a plurality of real-time applications; and

a plurality of other non-real-time applications.

3. The system as recited in claim 1 wherein said host further comprises:

a radio interface layer; and

an IP stack.

4. The system as recited in claim 1 wherein said non-access stratum further comprises:

an internal quality of service controller configured to receive and apply quality of service rules; and

a quality of service enforcement function configured to apply said quality of service rules.

5. A method of configuring internal quality of service, comprising:

making a quality of service request from a radio interface layer;

translating said quality of service request into an AT command;

providing said AT command to an AT command interpreter;

translating said AT command into a quality of service rule; and

providing said quality of service rule to an internal quality of service controller.

6. The method as recited in claim 5 wherein said AT command is a proprietary command.

7. The method as recited in claim 5 wherein said AT command is a standard-based AT command, and wherein said internal quality of service is configured as a fallback if a requested standard based QoS is not granted.

8. The method as recited in claim 5 wherein said quality of service rules comprise discard selection criteria.

9. The method as recited in claim 5 wherein said quality of service rules further comprise prioritization criteria.

10. The method as recited in claim 5 wherein said quality of service rules further comprise proprietary deep inspection patterns to identify traffic flows.

11. A method of enforcing internal quality of service, comprising:

identifying data packets internal to a non-access stratum of a modem;

associating a quality of service policy to said data packets internal to said non-access stratum of a modem; and

applying said quality of service policy to said data packets internal to said non-access stratum of a modem.

12. The method as recited in claim 11 wherein said identifying said data packets is enabled by an existing standards-based framework.

13. The method as recited in claim 11 wherein said identification of said data packets is enabled by deep packet inspection.

14. The method as recited in claim 11 further comprising receiving an AT command;

and

basing said quality of service policy on at least one quality of service rule determined by said AT command.

15. The method as recited in claim 11 wherein said applying of said quality of service policy to said data packets is enabled by a custom configuration.

16. The method as recited in claim 11 wherein said applying comprises:

limiting buffered data within an access stratum of said modem while avoiding underrun; and

prioritizing packets for transmission within said non-access stratum based on quality of service policy.

17. The method as recited in claim 11 wherein said applying comprises discarding packets based on a quality of service policy.

18. The method as recited in claim 11 wherein said applying is carried out on a data bearer basis.
