The invention relates to a method for controlling the load of a data concentration gateway (3) for a wireless communication network (1). The method comprises: - 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 between the communication start date of the selected data signal and the communication end date of the selected data signal, - comparing said 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.
