In a method and an arrangement for using certain data acquired upon registration of a mobile communication device of a mobile subscriber of a cellular provider at a switching center, in particular for traffic forecasting, wherein the acquired data comprise at least a numerical identification associated with the person of the subscriber and time and location of registration at the switching center, the numerical identification is used at least partially as an argument of a true one-way function or pseudo one-way function for calculating a functional value. The functional value is associated with the acquired data, especially time and location of the registration. The acquired data including the functional value but without the numerical identification are transmitted to a unit using the data. |
