The present invention relates to a method and apparatus for optimizing radio coverage and power consumption within a mobile communication network (1). In accordance with an embodiment of the invention, radio measurements (UE_meas1; BS_meas1; BS_meas2) carried out by subscriber devices (11) and/or radio base stations (21; 23), as well as user geographical locations (UE_pos1; UE_pos2; UE_pos3) at the time the radio measurements have been carried out, are gathered. Antenna geographical locations (ant_pos22; ant_pos23) are then derived from the radio measurements and the user geographical locations, and radio propagation models (rpm22; rpm23) from the antenna geographical locations that best fit the radio measurements at the user geographical locations. The so-derived radio propagation models from the so-derived antenna geographical locations are then supplied to a radio resource controller (41) for activation of dormant cells (C22; C23).
