Abstract

A communication device for a subscriber in a communication network of coequal subscribers, which communication device has a communication unit and a control unit. The received messages are checked for rule compliance. If a message does not comply with a particular rule, a disconnection signal is sent to the transmitter of the message.

Claims

1-45. -45. (canceled)

16. A communication device for communication with a coequal subscriber, said communication device comprising:

a communication unit for receiving a message from an adjacent subscriber; and

a control unit for checking whether the received message complies with a particular rule, and for triggering disconnection of a transmitter if this is not the case.

17. The communication device as claimed in claim 16,

wherein the communication device is a vehicle communication device in a vehicle;

and

wherein the adjacent subscriber is a communication device in an adjacent vehicle.

18. The communication device as claimed in claim 16,

wherein the transmitter is part of the communication unit in the adjacent vehicle.

19. The communication device as claimed in claim 16,

wherein the communication device is configured to transmit a disconnection command generated by the control unit to the transmitter for the purpose of triggering the disconnection.

20. The communication device as claimed in claim 19,

wherein the communication device is configured to evaluate disconnection commands received by the transmitter and to deactivate at least one of the transmitter and a receiver if the result of the evaluation is that it is necessary to disconnect the transmitter.

21. The communication device as claimed in claim 16,

wherein the communication device is configured to disconnect the transmitter at the level of a communication chip in the transmitter.

22. The communication device as claimed in claim 21,

wherein the communication chip has a processor which is integrated in the hardware of the chip;

and

wherein the processor is configured to disconnect the chip.

23. The communication device as claimed in claim 16,

wherein the transmitter is part of the communication unit in the vehicle.

24. The communication device as claimed in claim 23,

the communication device is configured to automatically recognize an error in a reception channel of the transmitter by counting received messages given a different number of transmitted data packets per unit time.

25. The communication device as claimed in claim 16,

the communication device is configured to change a vehicle identification at stipulated times.

26. A communication network, having a plurality of communication devices as claimed in claim 16.

27. A vehicle having a communication device as claimed in claim 16.

28. A method for communication with a coequal subscriber, said method comprising:

receiving a message from an adjacent subscriber;

checking whether the received message complies with a particular rule; and

triggering disconnection of a transmitter if the received message does not comply with the particular rule.

29. A program element which, when executed on a processor in a communication device, instructs the processor to perform the following steps:

receiving a message from an adjacent subscriber;

checking whether the received message complies with a particular rule; and

triggering disconnection of a transmitter if the received message does not comply with the particular rule.

30. A computer-readable medium which stores a program element which, when executed on a processor in a communication device, instructs the processor to perform the steps comprising:

receiving a message from an adjacent subscriber;

checking whether the received message complies with a particular rule; and

triggering disconnection of a transmitter if the received message does not comply with the particular rule.
