Abstract
A method is provided for detecting scrambling of a radiocommunication network. The method is applied by a radiocommunication circuit capable of being connected to the network by being synchronized on a radiocommunication channel. The method includes a final detection phase, having the following steps: detection of verification of the following final condition: there are N radiocommunication channels on which the radiocommunication circuit cannot be synchronized despite detection of a power level normally sufficient for being synchronized, where N>2; and if the final condition is verified, generation of a final scrambling signal with a probability of scrambling equal to 100%. The method also includes at least one intermediate detection phase, having the following steps: detection of verification of at least one intermediate condition; and if the at least one intermediate condition is verified, generation of an intermediate scrambling signal with a probability of scrambling of less than 100%.
