Abstract: The invention concerns a method which consists, in a radio communication system comprising a core network, at least one radio network controller connected to the core network and configured to control radio communications with terminals and at least one operation center capable of supervising said radio network controller, in: transmitting from the operating center to a radio network controller, a coded list of terminal identifiers; transmitting the coded list to the control network from the radio network controller; decoding the coded list at the core network; detecting at the core network a radio communication under the control of the radio network controller, with a terminal identified in the decoded list; and instructing the radio network controller, from the core network, to start a recording of events concerning the detected communication.
