Abstract
The present invention relates to an apparatus and method for controlling a number of user equipments operating in a cellular network. The method comprises receiving an indication that a rise-over-thermal (RoT) measured in a cell is above a threshold. In response to reception of the indication, it is determined (52) if a user equipment, which is in a Radio Resource Control, RRC, state CELL_DCH and served by the cell, has a low data activity in the uplink According to the method, a user equipment, which is in the RRC state CELL_DCH, is served by the cell and is determined to have a low data activity in the uplink, is triggered (54) to change state to a RRC state CELL_FACH. Thereby the contribution of the user equipment to the RoT of the cell may be reduced and it may be possible to avoid dropping users due to congestion control in case of unacceptably high RoT in the cell.
