The invention proposes a method for controlling calls in a radiocommunication network arranged for routing incoming calls to radio terminals and out-going calls from radio terminals. According to the method, responsive to a command, at least some of the incoming calls intended for radio terminals located in at least one determined area are prevented from being routed to said radio terminals by the radiocommunication network, while the out-going calls from radio terminals located in said at least one determined area keep on being routed by the radiocommunication network.
