Abstract
A computer implemented process compares signals communicated between a known position and a plurality of base stations in a cellular telephone system to determine the level of interference with a signal on a channel expected to serve the known position, and determines a value indicating a probability of interference with a signal on a channel expected to serve the known position.
Claims10
A computer implemented process comprising the steps of:
- identifying a first signal on a channel expected to serve a known position in a cellular telephone system;
- comparing additional signals communicated between the known position and a plurality of base stations in the cellular telephone system to determine a level of interference of each of the additional signals with the first signal;
- and
- determining a first probability of interference value at the known position, wherein the step of determining the first probability of interference includes the steps of:
- combining for each of the additional signals a probability of receipt of such signal and a weighting indicating the level of interference to be expected from such signal at the known position to determine an effect for such signal, and
- combining the effects for all of the additional signals to determine the first probability of interference value for the first signal at the known position.

A computer implemented process comprising the steps of:
- combining values indicating strength of signals communicated between each of a plurality of closely adjacent known positions and a plurality of base stations in a cellular telephone system to determine average strengths of signals communicated between an average known position and the plurality of base stations,
- comparing the average strength of signals communicated between an average known position and a plurality of base stations in a cellular telephone system to determine the level of interference with a signal on a channel expected to serve the average known position, and
- determining a value indicating a probability of interference at the average known position.
