Providing quality of service for various traffic flows in a communications environment
View Patent ↗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.

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 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:

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.

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:
