Abstract

A system for transmitting a warning message via a radio network has a transmitter (1) and at least one receiver (2). The transmitter (1) has an antenna for transmitting the warning message (14) over the radio network. The warning message (14) transmitted by the transmitter (1) includes parameters (18) of a warning area, a warning reason (15) and warning behavior (16). The receiver has an antenna (3) for receiving the warning message (14) transmitted via the radio network, a decoder (4), a processor (5), a memory (6) in which the location of the receiver (2) by geographic coordinates is stored and a warning output unit (7). In the processor (5) the received warning message (14) is captured and read out by means of a capture algorithm. The warning area is determined from the parameters (18) of the warning message (14) by using a zone algorithm. An analysis logarithm verifies whether the location stored in the receiver (2) is within the warning area, and if this is the case, a warning signal is generated and outputted by the warning output unit (7). The invention also comprises a receiver (2) for receiving a warning message (14) as well as a method for reception in a receiver (2) and a method for transmitting a warning message (14) in a radio network having a transmitter (1) and a receiver (2).
