Abstract: Managing communication in an orthogonal frequency division multiple access (OFDMA) system using segments in an OFDMA frame is accomplished by setting at least a first segment in the OFDMA frame as a high power segment for a plurality of base station in the OFDMA system. Further, communication is established between at least one base station and at least one communication device in the OFDMA system, in response to setting the at least first segment as a high power segment. Managing the communication further includes assigning a region of the first segment to a set of base stations in the OFDMA system. The assigned region can be used by the set of base stations at high power level to communicate with communication devices located in overlapping areas.

Abstract: The present invention provides a method and system for positioning one or more anchor nodes or one or more non-anchor nodes in one or more communication networks. A non-anchor node may be in communication with two or more anchor nodes. The method comprises determining two or more distance measurements, corresponding to raw distances of the non-anchor node from the two or more anchor nodes, at predetermined intervals of time. An estimated distance is then calculated between the two or more anchor nodes based on the two or more distance measurements. Estimated distances between a plurality of anchor nodes in the one or more communication networks is calculated in a similar manner. A partial distance matrix is then populated using the estimated distance between the plurality of anchor nodes. A plurality of geographic coordinates of the plurality of anchor nodes is reconstructed based on the partial distance matrix.

Abstract: As part of mobility management messaging in current systems, only static quality of service (QoS) profiles and their statically configured classifiers are reported. These classifiers are known a priori and are typically used for hosted traffic. Once advanced application classifiers are matched and mobility messaging is done, the deep packet inspection (DPI) learned subscriber context is lost. An embodiment of the invention is configured to associate DPI-learned dynamic classifiers with the classifier's policy information as payload over mobility management messaging. The embodiment is useful for identifying protocols and applications, for authentication purposes, solving congestion—based issues between elements in a network, guaranteeing QoS without reserving resources statically, attaching traffic packets to a particular subscriber, and creating mobile signaling to provision end-to-end communication in a network.

Abstract: In this invention, adaptive resource allocation is proposed. A resource is divided into Blocks and each base station is assigned a Block for its terminals that are in the interference region, and another Block for its terminals that are not in the interference region. Blocks other than these two are not used by the base station. Bordering base stations does not use the same Block if they have any terminal in the shared interference region. Another embodiment of the invention proposes resource sizing along with load balancing scheme. Resource sizing is defined as determining the size of the resources allocated for each Block. This is adaptable and can change over time according to topology. Another embodiment of the invention proposes a handover method for some terminals in order to increase the Block utilization by handing a terminal over another base station. Final embodiment of the invention proposes an adaptive control scheme that defines multiple policies for different topologies.
