Abstract

The claimed subject matter relates to providing appropriate QoS treatment to one or more traffic flows associated with a terminal, wherein the QoS treatment is defined within a profile assigned to the terminal and implemented when the terminal requests access to a network. An access mode can receive identifying indicia associated with the terminal and relays such indicia to an authentication and authorization server (AAS). The AAS can thereafter provide the access node with a profile that defines QoS treatment to associate with one or more traffic flows related to the terminal.

Claims

1. A method for configuring QoS with respect to a terminal, comprising:

receiving identifying indicia associated with the terminal; and

subsequently delivering a profile to an access node that is communicatively coupled to the terminal after receipt of the identifying indicia, the profile including;

a first service class element and filter rule pair corresponding to an egress traffic service relating to egress traffic from an access node to a subscriber, said first service class element and filter rule pair including;

i) a first service class element that includes parameters that prescribe a first QoS treatment and ii) a first set of one or more filter rules that identify an egress traffic flow to be provided the first QoS treatment; and

a second service class element and filter rule pair corresponding to an ingress traffic service relating to ingress traffic from a subscriber to an access node, said second service class element and filter rule pair including;

i) a second service class element that includes parameters that prescribe a second QoS treatment and ii) a second set of one or more filter rules that identify an ingress traffic flow to be provided the second QoS treatment.

2. The method of claim 1, further comprising performing authentication and authorization with respect to the terminal based at least in part upon the identifying indicia.

3. The method of claim 1,

wherein said second QoS treatment is different from said first QoS treatment.

4. The method of claim 1, further comprising delivering the profile to multiple access nodes that are communicatively coupled to the terminal after receipt of the identifying indicia.

5. The method of claim 1,

wherein said profile is a profile assigned to said terminal, said terminal being a mobile wireless terminal;

and

wherein said first service class element of said profile includes;

a max rate element indicating a maximum data rate that can be provided to a traffic flow associated with the first service class.

6. The method of claim 1,

wherein said profile is a profile assigned to said terminal, said terminal being a mobile wireless terminal;

and

wherein said first service class element of said profile further includes;

a sharing weight element indicating a relative proportion of resources that a traffic flow associated with the first service class element should receive when competing with outer traffic flows.

7. The method of claim 6, wherein said first service class element further includes:

a minimum rate element indicating a minimum data rate that can be provided to a traffic flow associated with the first service class.

8. The method of claim 1,

wherein said profile is a profile assigned to said terminal, said terminal being a mobile wireless terminal;

and

wherein said first service class element of said profile further includes;

a compression hint element including information used in determining at least i) a type of compression applicable to packets belonging to a traffic flow corresponding to the first service class element or ii) parameters needed for compression of packets belonging to a traffic flow corresponding the first service class element.

9. The method of claim of claim 1,

wherein said profile is a profile assigned to said terminal, said terminal being a mobile wireless terminal;

and

wherein said first service class element includes;

parameters needed for compression of packets belonging to a traffic flow corresponding the first service class element.

10. The method of claim 9, wherein said profile further includes:

a service element including a grouping of parameters associated with establishing and maintaining connectivity by way of an air interface.

11. The method of claim 1, wherein at least one of said first and second service class elements in said profile is associated with a location constraint profile included in said profile, said location constraint profile prescribing points of attachment or locations through which a subscriber may be granted access for services.

12. The communications apparatus of claim 11, wherein presence of said location constraint profile indicates that access to services is to be limited to prescribed points of attachment or locations.

13. The method of claim 1, wherein said first set of one or more filter rules includes rule priority information indicating the order in which a filter rule should be applied with respect to another filter rule included in said first set of filter rules.

14. The method of claim 1, wherein said first set of one or more filter rules includes rules for discarding packets belong to a packet flow.

15. A communications apparatus, comprising:

means for receiving identifying indicia associated with a wireless terminal that is requesting access to one or more network services; and

means for subsequently delivering a profile to an access node that is communicatively coupled to the terminal after receipt of the identifying indicia, the profile including;

a first service class element and filter rule pair corresponding to an egress traffic service relating to egress traffic from an access node to a subscriber, said first service class element and filter rule pair including;

i) a first service class element that includes parameters that prescribe a first QoS treatment and ii) a first set of one or more filter rules that identify an egress traffic flow to be provided the first QoS treatment; and
