Abstract

Providing a quality of service for a mobile node includes facilitating a communication session for the mobile node. A quality of service decision factor of a context of the communication session is established. A quality of service associated with the quality of service decision factor is identified. Whether to provide the quality of service to the mobile node for the context is determined.

comparing at least one standard filter to the one or more ports, the at least standard filter associating the one or more ports to the quality of service decision factor; and

establishing the quality of service decision factor in accordance with the comparison.

12. The network node of claim 7, the processor further operable to:

facilitate the communication session for the mobile node by;

exchanging one or more signaling messages for the communication session; and

establish the quality of service decision factor of the context of the communication session by;

establishing the quality of service decision factor from the one or more signaling messages.

13. The network node of claim 7, wherein:

the quality of service decision factor comprises at least one of the group consisting of a requested application, a requested service, and communicated content;

the processor is further operable to;

facilitate the communication session for the mobile node by;

facilitating a primary context for the communication session; and
