A method may include allocating channels of a wireless local area network (WLAN) including a plurality of access points to the plurality of access points based on a load of each access point. The load of each access point may include a user load and/or an interference load. The user load may be generated by each user of the access point. The interference load may be based on interference caused by transmissions between the remainder of the plurality of access points and users of the remainder of the plurality of access points.

Frequency planning method for wireless LANs

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.

Mobility access gateway

Unique identifiers are assigned to sets of adjacent access points in a wireless, local area network (WLAN). 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.

Methods and devices for associating a mobile device to access points within a WLAN

A gateway for mobile communications comprises a cache for storing network data recently downloaded from a network, a foreign agent, and a packet filter that directs requests for the network data from a mobile node to the cache. The packet filter directs the requested network data from the cache to the mobile node by way of the foreign agent, without forwarding the requested network data to a home agent of the mobile node.

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.

Fairness and load balancing in wireless LANs using association control

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.

User assignment strategies for hierarchical and other overlay networks

The present invention provides a method for scheduling mobile units in a wireless telecommunications network including first and second wireless connection points having a wireless communication link therebetween. The method includes determining a first number of mobile units having a wireless communication link with the first wireless connection point, determining a second number of mobile units having a wireless communication link with the second wireless connection point, and scheduling the mobile units based upon the first and second numbers.

Method for scheduling users in a hierarchical network

The adjacency of access points in a wireless, local area network is used to determine the existence of common overlapping access point coverage areas and to determine maximum distances between access points.
