Abstract

Apparatus and methods operable by a network in configuring quality of service (QoS) for an access terminal are operable to receive, at a network, a request for packet data access from an access terminal. The apparatus and methods are further operable to determine, at the network and based on establishment of the packet data access, an initial QoS policy configuration for at least one reservation link corresponding to at least one application on the access terminal, wherein the initial QoS policy configuration is based on preconfigured information and comprises initial QoS parameters for the at least one application. Additionally, the apparatus and methods are operable to establish the at least one reservation link with the access terminal, prior to initiation of the at least one application on the access terminal, wherein the at least one reservation link includes the initial QoS parameters for the at least one application.

4. The method of claim 2, wherein establishing the communication link further comprises turning off the at least one reservation link.

5. The method of claim 2, further comprising receiving a reservation link activation request from the access terminal or determining by the network that the reservation link should be activated, and further comprising turning on the reservation link.

6. The method of claim 5, wherein the reservation link activation request is based on a call originated by the access terminal.

7. The method of claim 5, wherein the reservation link activation request is based on a call terminated by the access terminal.

8. The method of claim 1, wherein the preconfigured information comprises subscriber information including a QoS user profile.

9. The method of claim 8, further comprising deriving the initial QoS parameters from the QoS user profile based on an access network used by the access terminal.

10. The method of claim 1, wherein the initial QoS policy configuration comprises policy rules for the at least one application and each policy rule comprises at least one of full or partial packet filters and the initial QoS parameters for the at least one application.

11. The method of claim 1, wherein the initial QoS parameters comprise at least one of maximum authorized aggregate bandwidth for best effort traffic, authorized flow profile IDs for each direction, maximum per flow priority, allowed differentiated services markings, inter-user priority for best effort, mapping between QoS class and Differentiated Services Code Point (DSCP), and mapping between QoS class and Token Bucket Parameters.

12. The method of claim 1, wherein the determining occurs without input from the access terminal.

13. The method of claim 1, further comprising updating the initial QoS configuration with new QoS parameters subsequent to establishing the reservation link.

14. At least one processor operable by a network in configuring quality of service (QoS) for an access terminal, comprising:
