The invention relates to a method for controlling the load of a data concentration gateway for a wireless communication network, the method comprising: —receiving a plurality of data signals from a plurality of remote client devices, —providing the communication start date of each data signal received, —selecting a received data signal, —determining a communication end date of each data signal received, —determining a number of data signals received by the gateway that are different from the selected data signal, which have a communication end date that is between the communication start date of the selected data signal and the communication end date of the selected data signal, —comparing the number of data signals to a threshold number, and —emitting an alarm signal in response to the detection that the number of data signals is greater than the threshold number.
