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.
