Abstract
A method and system of optimizing the signal strength and interference characteristics of a wireless telecommunications network which includes a plurality of cells with at least one of the cells being disturbed (the “disturbed cell”) by events occurring in one or more offending cells. The method comprises the step of computing a distribution of disturbance events in the disturbed cell as a function of disturbances created by the offending cells. The distribution of disturbance events is then utilized to predict changes in coverage of the offending cells as changes in the carrier-to-interference (C/I) ratio of the disturbed cell are made. Such predictions then lead to modifying the power levels of wireless components in the network to reach acceptable tradeoffs between interference and coverage. Thus, the tradeoff is a function of the predicted changes in C/I and acceptable coverage and interference thresholds for the network.
