ABSTRACT:
Signal strength measurements for different frequencies in different cells are calibrated in a cellular communications system. The signal strength of first and second frequencies in at least one cell of a plurality of cells is repeatedly measured. A measurement history is created for said first and second frequencies in at least the one cell. Each measurement history is based on the signal strength measurements of one of the first and second frequencies in the respective one cell. The measurement histories are stored. A respective correction factor is determined for each possible pair of first and second frequencies in at least the one cell. Each correction factor is based on the stored measurement history of the first and second frequencies in the pair. The respective correction factor for a pair of first and second frequencies cell is applied when comparing the signal strength measurements of the first and second frequencies in said pair.
