Claim Text:
1. A method, in a cellular network, of localized congestion exposure for efficient resource management of flows of downlink traffic destined to a user device, the method comprising: receiving the flows of the downlink traffic from a server coupled to the cellular network, wherein the server does not support congestion exposure; receiving congestion feedback, from an eNodeB, wherein the congestion feedback is indicative of a congestion caused by the flows of the downlink traffic in a local path within the cellular network between a packet data network gateway and the eNodeB; declaring, in response to the congestion feedback, congestion exposure (CONEX) information for the flows of the downlink traffic; monitoring, at the packet data network gateway within a core network, the CONEX information, wherein the core network and the eNodeB are part of the cellular network; and responsive to said monitoring, acting, at the packet data network gateway, on the flows of the downlink traffic destined to the user device according to an operator's policy, wherein the user device does not support congestion exposure.
