Dynamic adaptation of detection of requests to access a cellular communications network as a function of the radio environment associated with the requesting communications equipment
First Claim
1. A signal processing device (D) for a cellular communications network, said device (D) comprising processing means (MT) adapted to effect preamble detection, as a function of detection parameters, on each signal sent by a requesting terminal (UE) in an authorized access slot and representative of a preamble of a request to access said network associated with an authorized signature, which device is characterized in that said processing means (MT) are adapted, on receiving a signal requesting access to the network sent by a requesting terminal (UE), to determine a value for at least one detection parameter chosen as a function of at least one selected parameter representative of the radio environment of said requesting terminal so as to adapt the detection of said received signal dynamically as a function of the radio environment of said requesting terminal (UE).

Abstract
A signal processing device (D) is installed in a base station (Node B) of a cellular communications network, for example. Said device (D) comprises processing means (MT) adapted to effect preamble detection, as a function of detection parameters, on each signal sent by a requesting terminal (UE) in an authorized access slot and representative of a preamble of a request to access the network associated with an authorized signature. The processing means (MT) are adapted, on receiving a signal requesting access to the network sent by a requesting terminal (UE), to determine a value for at least one detection parameter chosen as a function of at least one selected parameter representative of the radio environment of the requesting terminal so as to adapt the detection of the received signal dynamically as a function of the radio environment of the requesting terminal (UE).
