ABSTRACT:
Non-uniform spatial loads are estimated for a plurality of bins corresponding to a cellular wireless territory served by Base Station Transceivers (BTS's). Using means and standard deviation of signal strength received at each of the bins from each of the BTS's, probabilities are computed for each bin such that each of the BTS's will serve the bin. Using the computed probabilities and an estimated offered load for each BTS, which load is derived from carried load and call lost measurements at the BTS, a resource constraint is then expressed for each BDS in terms of the bin offered load estimates. Next, using an approximation of relative demand for wireless services across all bins, based, for example, on demographic data, a performance function is expressed for each bin in terms of the bin's estimated offered load. Using the performance function a lexicographic minimax objective function is defined, which is then coupled with the resource constraints to express an equitable resource allocation model. Finally, the optimal solution to the model is determined thereby providing the bin offered load estimates.
