Abstract
Abstract System and apparatus for actively managing calls in a wireless cellular network. A host receives input data from a plurality of cells regarding the status of calls in that cell. Input data may include call variables such as carrier signal strength over interference (C/I), forward and reverse link power, beam and channel assignments, handoff status, and triangulation data regarding location/movement of active calls. The host processes the input data with reference to known cell neighborhoods, and creates output data for each cell that includes information on other active calls in the neighborhood. The output data then updates the cell with information regarding active calls in the cell's vicinity. The cell may then make adjustments to call variables taking into account local interference conditions. Further, through reference to (1) fixed data regarding the network such as topography or statistics, and/or (2) immediate past historical data regarding active calls, the host may also create output data taking into account predicted impending interference conditions.
