Abstract

Method and apparatus for processing packet flows in a communication system. In one embodiment, a resource reservation message includes packet flow parameter information used to determine flow treatment of the associated packet flow. The packet flow mapping is based on the quality of service of the associated packet flow. In another embodiment, a bearer connection is established and monitored for information relating to flow treatment.
