1. A method for predicting a state of a cell in a radio access network, RAN, the method comprising:
obtaining information of the cell;
determining one or more sets of conditions based on the obtained information, at least one of the one or more sets of conditions indicating a decrease of a Random Access Channel, RACH, success rate;
predicting that the cell will enter a sleeping state when at least one set of the one or more sets of conditions is fulfilled; and
outputting an action to prevent the cell from entering the sleeping state based on a probability and a number of wireless devices currently connected to the cell.
