Processing device for the transmission of measurements taken by radio terminals
First Claim
1. A processing device for at least one communication terminal capable both of receiving data broadcast by a radio communication network in point-to-multipoint mode over a physical broadcast channel and using an adaptable modulation and coding scheme, and of determining measurements representative of the radio conditions present in at least the cell in which the communication terminal is located, comprising a processing module configured to generate status messages each comprising data representative of the value of at least one measurement taken by said radio terminal and to order said radio terminal to transmit the status messages to said radio network over an authorized random access channel, for at least said cell in question;
- wherein the communication terminal transmits a given status message, concurrently with at least one other communication terminal that has a common status at a given moment, using a common portion of a time/frequency/code domain reserved for the given status message.

Abstract
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.
