FAIR CONGESTION DETECTION FOR TRANSPORT NETWORK LAYER WCDMA COMMUNICATIONS
First Claim
1. A method for detection and notification of congestion in a radio access transport network including one or more radio network controllers coupled to one or more radio base stations, comprising:
- monitoring data packet flows, each data packet flow associated with a mobile radio terminal communication and being controlled in the radio access transport network by a corresponding flow control entity, for congestion in the radio access transport network;
detecting a congestion area in the radio access transport network for one of the monitored data packet flows;
determining whether one or more other monitored data packet flows share the detected congestion area; and
communicating congestion notification information to one or more of the flow control entities corresponding to the one or more other monitored data packet flows that share the detected congestion area so that the informed one or more of the flow control entities may take a flow control action based on the congestion notification information.

Abstract
Congestion is detected in a radio access transport network including one or more radio network controllers each coupled to one or more radio base stations. Multiple data packet flows are each associated with a mobile radio terminal communication, and each flow is controlled in the radio access transport network by a corresponding flow control entity. They are monitored for congestion in the transport network. If a congestion area in the transport network is detected for one of the monitored data packet flows, then a determination is made whether other monitored data packet flows share the detected congestion area. Congestion notification information is communicated to the flow control entities corresponding to the other monitored data packet flows that share the detected congestion area. Based on the congestion notification information, the informed flow control entities may take a flow control action, e.g., to enable fair sharing of communications resources in the transport network.
