Abstract: The invention includes a method and apparatus adapted for providing quality-of-service to a packet flow within a Radio Access Network (RAN). In one embodiment, a method includes receiving packets of a packet flow at a first network element of the RAN, where the packet flow is associated with an application normally served in a best effort service class of the RAN and each packet of the packet flow comprises an indication of a quality-of-service policy to be applied to the packet flow within the RAN, and, applying the indicated quality-of-service policy to the packet flow within the RAN. The quality-of-service policy to be applied to the packet flow within the RAN is based on at least one characteristic of the packet flow, which may be determined in any manner, such as using information included in the packet headers, using deep packet inspection techniques, and the like. The indication of the quality-of-service policy to be applied to the packet flow within the RAN may be set either inside the RAN or outside the RAN.

Abstract: The invention includes a method and apparatus adapted for controlling congestion in a Radio Access Network (RAN). In one embodiment, a method includes monitoring packets received at a first network element of the RAN for an indication of congestion, where the packets are associated with a quality-of-service class, and, in response to detecting an indication of congestion in at least one of the received packets, signaling congestion status information from the first network element of the RAN toward a second network element of the RAN that is adapted for applying congestion control for the quality-of-service class. In one embodiment, a method includes receiving, at a first network element of the RAN, from a second network element of the RAN, congestion status signaling indicative of a congestion condition associated with a quality-of-service class, and applying congestion control for the quality-of-service class in response to receiving the congestion status signaling indicative of the congestion condition.
