Abstract
A method and a radio beacon for transmitting messages between a radio beacon and multiple onboard units passing this with unique identifiers in a road toll system, wherein the messages respectively provided with an identifier of an onboard unit are stored in a buffer memory of the radio beacon for sequential processing or despatch. The method including determining, of each onboard unit entering the transmitting-receiving area of the radio beacon, at least one characteristic of the onboard unit, sorting the messages present in the buffer memory under the identifiers depending on the characteristics determined for these identifiers, and sequentially processing or despatching the messages from the buffer memory in the sequence they were sorted.

A method for transmitting messages between a radio beacon and multiple onboard units with unique identifiers in a road communication system, wherein the messages provided with an identifier of a respective onboard unit are stored in a buffer memory of the radio beacon for sequential processing or despatch, the method comprising:
- determining, for each onboard unit entering a transmitting-receiving area of the radio beacon, at least one characteristic of the onboard unit by receiving, in the radio beacon, information transmitted with a message from the onboard unit relating to a characteristic of the onboard unit;
- sorting the messages present in the buffer memory under the identifiers, depending on the characteristics determined for each identifier;
- and
- sequentially processing or despatching the messages from the buffer memory in the sequence they were sorted.
A radio beacon for a road communication system for transmitting messages between the radio beacon and multiple onboard units with unique identifiers, comprising:
- at least one buffer memory, in which the messages respectively provided with an identifier of an onboard unit are stored for sequential processing or dispatch;
- and
- a transceiver coupled to the buffer memory, the transceiver comprising:
- a determining means for determining for each onboard unit entering the transmitting-receiving area of the radio beacon whether a message from an onboard unit is related to at least one characteristic of the onboard unit, and
- a sorting means for the buffer memory coupled to the determining means and configured to sort the messages present in the buffer memory under the identifiers, depending on the characteristics determined for each identifier.
