Dynamic adaptation of the detection of access requests to a mobile radio network depends on the radio environment of the requesting komunikationsendgeräts

摘要

A signal processing device (d) is installed, for example, in a base station (node b) of a cellular communications network. This device (d) comprises processing means (mt) responsible for performing a detection of the preamble, on each signal transmitted by a calling terminal (eu) in a time slice of access is authorized and representative of a preamble of the request for access to the network associated with a signature, as a function of parameters for detecting. The processing means (mt) are also adapted to receive a signal of the request for access to the network transmitted by a calling terminal (eu), to determine a value of use for at least one parameter of the detection chosen as a function of a value of at least one parameter selected representative of the radio environment of the calling terminal, so as to adapt dynamically the detection of the received signal as a function of the radio environment of the calling terminal (eu).
