Determination of optimal handover boundaries in a cellular network based on traffic distribution analysis of mobile measurement reports

Abstract

Traffic distributions in a cellular network tend to follow periodic patterns where local congestions occur. By optimizing handover boundaries between neighboring cells, opportunities for load sharing can be exploited to maximize the capacity of the cellular network as a whole. We propose a method for determining optimal handover boundaries by analyzing historical measurement reports data, as an indication of traffic distribution patterns within the network; and modeling the problem as an optimization problem with a set of nonlinear constraints.
