摘要：The invention relates to a method and system for reducing traffic flow from asending network element to a mobile element during handoff situations when the

connection of the mobile element is switched, or to be switched, over from a firstnetwork access element to a second network access element. When the mobile elementdetects, or is informed on, a handoff process to be initiated, a procedure is initialised forreducing the traffic flow from the sending network element to the mobile element. Theprocedure for reducing the traffic flow preferably comprises employing an optimizationprocess, preferably a TCP optimization process, e.g. delaying the sending of an

acknowledgement message from the mobile element to the sending network element,or to reduce the value of the field “advertised window” of the acknowlegdementmessage to a smaller value than the actually appropriate value.
