Abstract

The invention pertains to a computer-implemented method for optimizing an assignment of frequencies (f) to cells (C) of a mobile communications network (1). The cells (C) are distributed for communication within the mobile communications network (1). A set of unplanned cells (2) in the mobile communications network (1) is specified. For each unplanned cell (2) a set of frequencies (f) to be potentially assigned to this unplanned cell (2) is specified. Frequency interference probabilities (p) of selected cell pairs are calculated, wherein each cell pair defines a relation of an unplanned cell (2) to another cell (c) within the mobile communications network (1). Then, terms of a stress function are formulated, each term connecting a calculated frequency interference probability (p) of a respective cell pair with a frequency relation between the cells (2, c) of the respective cell pair. An optimized assignment of frequencies (f) is determined by using a quantum concept processor (7), thereby selecting for each unplanned cell (2) a sub-set of frequencies (f) from the respective set of frequencies, such that the stress function is minimized.
