Using the ECN mechanism to signal congestion directly to the base station

摘要

Techniques for a mobile station to signal a request for a reduction in data transmission rate to a base station are disclosed. An example method for facilitating flow control in a wireless communication system includes monitoring resource use associated with a mobile station and, based upon the resource use, setting a congestion indicator in a header of at least one uplink traffic data packet. The uplink traffic data packet is then sent to a wireless base station, which detects the congestion indicator. In some embodiments, ECN bits in an IP header of the uplink traffic data packet are set. In other embodiments, ECN bits in an IP header of a downlink traffic data packet are set, to trigger the generation of a TCP header that indicates congestion in subsequent uplink packets.
