Abstract: A gateway for mobile access includes a foreign agent that receives user profile data and session state data from a home authentication, authorization and accounting (AAA) system of a mobile node, and a dynamic packet filter that performs multi-layer filtering based on the user profile data. The foreign agent transfers a session from a first network to a second network without session interruption, using the session state data, when the mobile node moves from the first network to the second network. The packet filter permits Internet access by the mobile node without passing Internet data requested by the mobile node through the first network.

Thereafter, a unique identifier may be forwarded to a mobile device which uses the identifier to associate itself with one of the adjacent access points. Associating a mobile device with an adjacent access point using unique identifiers allows a WLAN to meet its load balancing objectives.

Abstract: Association control is utilized for associating wireless local area network users with at least one wireless local area network access point and thereby achieving simultaneous fairness and load balancing. In the present method, a network operation center receives user parameters from each user in the wireless network via the access points. It then sets out both to determine a set of associations between each user and one or more access points based on the user parameters using fractional load balancing and produce a second set of associations by rounding so that, in said second set, each user is associated with only one access point. The present method achieves close to optimal load balancing and max-min fairness while outperforming commonly-used heuristic approaches.

Abstract: A hierarchical assignment manager (HAM) improves system throughput in a hierarchical overlay network by taking into account the requested data rates in addition to or instead of the velocities of mobile users within the network. The user population is characterized by the statistical description of their user profiles. The entire set of profiles is partitioned along assignment curves into two or more subsets, where each subset corresponds to the assignment to a particular layer of a hierarchical network. The HAM determines assignment curves to optimize the total effective system throughput in a systematic way and can be adapted to time-varying user behavior and profiles. The HAM can be used to decide upon assignment strategies between different layers of an overlay architecture, between different available network technologies, or between competing service providers.
