Abstract

Systems and methods are provided that facilitate active queue management of internet-protocol data packets generated in a data packet switched wireless network. Queue management can be effected in a serving base station as well as in an access terminal, and the application that generates the data packets can be executed locally or remotely to either the base station or access terminal. Management of the generated data packets is effected via a marking / dropping of data packets according to an adaptive response function that can be deterministic or stochastic, and can depend of multiple communication generalized indicators, which include packet queue size, queue delay, channel conditions, frequency reuse, operation bandwidth, and bandwidth-delay product. Historical data related to the communication generalized indicators can be employed to determine response functions via thresholds and rates for marking / dropping data packets.

Description

[0001] Claiming priority under 35 U.S.C. §119 [0002] This patent application claims priority to US Provisional Patent Application No. 60 / 868,711, filed December 5, 2006, entitled "METHOD AND SYSTEM FOR REDUCING BACKHAUL UTILIZATION DURING BASESTATION HANDOFF IN WIRELESS NETWORKS." This application is expressly incorporated herein by reference in its entirety. technical field [0003] The subject matter of the disclosure relates generally to wireless communications, and more particularly to base station handover in wireless communication systems. Background technique [0004] Wireless communication systems have become a ubiquitous means by which most people around the world communicate. Wireless communication devices have become smaller and more powerful in order to meet consumer needs and to increase portability and convenience. The increase in processing power in mobile devices, such as cellular telephones, has resulted in increased demands on wireless network transmiss...
