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

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

a control unit for;

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

transmitting a disconnect message to the adjacent subscriber communication device in response to the received message not complying with the particular rule, the disconnect message prompting the adjacent subscriber communication device to disconnect itself at a level of a communication chip in a transmitter of the adjacent subscriber communication device when the disconnect message is an Nth disconnect message received by the adjacent subscriber communication device, wherein N>

1.

2. The communication device as claimed in claim 1,

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.

3. The communication device as claimed in claim 1, wherein the transmitter is part of the communication unit in the adjacent vehicle.

4. The communication device as claimed in claim 1, 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.

5. The communication device as claimed in claim 4, 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.

6. The communication device as claimed in claim 1,

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.

7. The communication device as claimed in claim 1, wherein the transmitter is part of the communication unit in the vehicle.

8. The communication device as claimed in claim 7, 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.

9. The communication device as claimed in claim 1, the communication device is configured to change a vehicle identification at stipulated times.

10. A communication network, having a plurality of communication devices as claimed in claim 1.

11. A vehicle having a communication device as claimed in claim 1.

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

receiving a message from an adjacent subscriber communication device;

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

transmitting a disconnect message to the adjacent subscriber communication device in response to the received message not complying with the particular rule, the disconnect message prompting the adjacent subscriber communication device to disconnect itself at a level of a communication chip in a transmitter of the adjacent subscriber communication device when the disconnect message is an Nth disconnect message received by the adjacent subscriber communication device, wherein N>

1.

13. A non-transitory 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 communication device;

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

transmitting a disconnect message to the adjacent subscriber communication device in response to the received message not complying with the particular rule, the disconnect message prompting the adjacent subscriber communication device to disconnect itself at a level of a communication chip in a transmitter of the adjacent subscriber communication device when the disconnect message is an Nth disconnect message received by the adjacent subscriber communication device, wherein N>
