A method of managing a cellular network, the method comprising: step a) a node (100, 200) of the cellular network obtaining, for a given cell of the cellular network, reports of measurements performed by one or more communication devices associated with a surrounding cell of the given cell, each measurement indicating a received signal strength of a signal, RS, from the given cell; wherein each measurement further indicates a received signal strength of a signal,RS, received from the surrounding cell to which the communication device is associated, wherein each measurement further indicates received signal strengths of signals, RS, received from one or more further cells of the cellular network, said method being characterized in that the node (100, 200) performs step b), wherein step b) comprises performing, for each measurement, the sub-steps of: b1) calculating (320, 350) a difference between the received signal strength of the signal from said given cell and the received signal strength of the signal from said surrounding cell to which the communication device is associated; b2) checking whether any of the received signal strengths of the signals, RS, from said one or more further cell is higher than the received signal strength of the signal from said given cell, and b3) comparing the difference to a first threshold; and b4) in response to the difference being below said first threshold, incrementing a first counter only if any of the received signal strengths of the signals, RS, from said one or more further cell is higher than the received signal strength of the signal from said given cell; and in that the node performs step c) upon completion of step b), wherein step c) comprises the sub-steps of: c1) determining a first ratio of a value of the first counter and a total number of the measurements with respect to said given cell; and c2) on the basis of the first ratio and a configured threshold percentage of measurements above which said given cell is classified as a relevant interferer of said surrounding cell, classifying said given cell as a relevant interferer of the surrounding cell. step a) a node (100, 200) of the cellular network obtaining, for a given cell of the cellular network, reports of measurements performed by one or more communication devices associated with a surrounding cell of the given cell, each measurement indicating a received signal strength of a signal, RS, from the given cell;
