    • A method and apparatus for predicting a handover of a Mobile Station (MS) of a plurality of MSs to one or more target Base Stations (BSs) of a plurality of BSs in a wireless communication network. The method includes predicting a need for a handover of a MS to one or more target BSs selected from the plurality of BSs based on a handover threshold. The handover threshold is associated with a quality of a signal received by the MS. The method further includes transferring datapath associated with the MS to one or more of the one or more target BSs and one or more gateways prior to the handover of the MS. The one or more gateways are associated with one or more of a serving BS associated with the MS and the one or more target BSs. The plurality of BSs includes the serving BS.

    • A wireless network allocates special base-station resources to mobile user devices in the inter-station overlapping fringes that are also serviceable by a neighboring base-station. Included-fringe mobile user devices interoperate with a base-station that has been assigned to handle those particular mobile user devices. If a central controller has assigned another base-station to service them, they are referred to as an excluded-fringe mobile user device. Mobile user devices that are not visible to other base-stations can access the general base-station resources, but not any of the special base-station resources reserved for overlapping fringe area use. If no mobile user devices are operating in the overlapping fringe areas, then all the special base-station resources can be returned to the main pool of general base-station resources. A global scheduler, one part of split-level scheduling, in the central controller determines the amount of special and general base-station resources. A local scheduler, another part of split-level scheduling, in the base station do fair-sharing of its resources among user devices within their allocated type of resources. Base station can use special base-station resource of others with electronically steering antennas together with network wide awareness of central controller to optimize the spectrum usage.
    • 无线网络将专用基站资源分配给也可由邻近基站服务的台站间重叠条纹中的移动用户设备。 包括边缘移动用户设备与被分配用于处理那些特定移动用户设备的基站互操作。 如果中央控制器已经分配了另一个基站来服务它们,则它们被称为排除边缘移动用户设备。 对其他基站不可见的移动用户设备可以访问通用基站资源,但不能访问用于重叠边缘区域使用的任何专用基站资源。 如果没有移动用户设备在重叠边缘区域中运行,则所有特殊基站资源都可以返回到一般基站资源的主池。 中央控制器中的全局调度器,分层调度的一部分决定了特殊和一般基站资源的数量。 基站中的本地调度器是分层调度的另一部分,在其分配的资源类型中的用户设备之间对其资源进行公平共享。 基站可以使用其他电子方向天线的特殊基站资源,以及中央控制器的网络广泛认知,以优化频谱使用。

    • 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. The plurality of geographic coordinates is reconstructed based on one or more of a geometric build-up algorithm, a shortest-path algorithm and a multidimensional scaling algorithm.
