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 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.

2. The method as recited in claim 1 wherein said AT command is a proprietary command.

3. The method as recited in claim 1 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.

4. The method as recited in claim 1 wherein said quality of service rules comprise discard selection criteria.

5. The method as recited in claim 1 wherein said quality of service rules further comprise prioritization criteria.

6. The method as recited in claim 1 wherein said quality of service rules further comprise proprietary deep inspection patterns to identify traffic flows.

7. 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.

8. The method as recited in claim 7 wherein said identifying said data packets is enabled by an existing standards-based framework.

9. The method as recited in claim 7 wherein said identification of said data packets is enabled by deep packet inspection.

10. The method as recited in claim 7 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.

11. The method as recited in claim 7 wherein said applying of said quality of service policy to said data packets is enabled by a custom configuration.

12. The method as recited in claim 7 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.

13. The method as recited in claim 7 wherein said applying is carried out on a data bearer basis.
