A processing device (D) acts on behalf of at least one radio terminal (UE) capable both of receiving data broadcast by a radio communication network in point-to-multipoint mode over a physical broadcast channel and according to an adaptable modulation and coding scheme, and of determining measurements representative of the radio conditions present in at least the cell in which it is located. This device (D) comprises processing means (PM) tasked with i) determining whether a measurement taken by at least one radio terminal (UE) corresponds to a status from among a set of predefined statuses, and ii) if so, to generate a message dedicated to the determined status and order the radio terminal (UE) to transmit this status message to the radio network within a portion of the time/frequency/code domain reserved within a signaling frame, for at least the cell in question.
