The invention provides a communication method for transmitting useful data and a corresponding communication system. The communication method is used for transmitting useful data between a first road user (2), at least one second road user (3) and a central communications equipment (4). According to the invention, the first road user (2) prepares a data package (11) and transmits the data package (11) to the central communications equipment (4), said data package (11) being assigned to a changing key (10) which is transmitted together with said data package (11). The first road user (2) transmits an identifier (9) together with the key (10) to the second road user (3), and the second road user (3) uses said key (10) to request the data package (11) assigned to said key from the central communications equipment (4) and assigns it to the first road user (2). The invention further relates to a communications system (1).
