Abstract

A communication device for a vehicle has a first communication unit and a second communication unit. The first communication unit is configured to communicate with a server via a first communication protocol. The second communication unit is configured to communicate with at least one further vehicle via a second communication protocol. The first communication unit is configured to receive from the server control information for the second communication protocol and to forward it to the second communication unit. The second communication unit is configured to perform, depending on the forwarded control information, at least one predetermined setting for communicating with the at least one further vehicle by use of the second communication protocol.

First claim

What is claimed is:

1. A communication device for a vehicle that communicates with a server, comprising:
a first communication unit configured to communicate with the server via a first communication protocol, the first communication unit comprising a first interface for establishing the communication between the first communication unit and the server;
a second communication unit configured to communicate with at least one further vehicle via a second communication protocol, the second communication unit comprising a second interface for establishing the communication between the second communication unit and the at least one further vehicle, wherein
the first communication unit is configured to receive control information from the server for the second communication protocol, and to forward the control information to the second communication unit, and
the second communication unit is configured to perform, depending on the forwarded control information, at least one predetermined setting for communicating with the at least one further vehicle by way of the second communication protocol.

2. The communication device according to claim 1 , wherein
the second communication unit is configured to prepare measurement information on the second communication protocol and to forward the measurement information to the first communication unit, and
the first communication unit is configured to receive the measurement information forwarded by the second communication unit and to send the measurement information to the server.

3. The communication device according to claim 2 , wherein
the measurement information comprises channel measurement information which has been determined by the second communication unit by a channel measurement.

4. The communication device according to claim 3 , further comprising:
a control unit configured to receive the control information for the second communication protocol forwarded by the first communication unit and to forward the control information to the second communication unit.

5. The communication device according to claim 4 , wherein
the control unit is configured to receive the measurement information which has been forwarded by the second communication unit and to forward the measurement information to the first communication unit.

6. The communication device according to claim 1 , further comprising:
a control unit configured to receive the control information for the second communication protocol forwarded by the first communication unit and to forward the control information to the second communication unit.

7. The communication device according to claim 1 , wherein
the second communication protocol is based on the IEEE 802.11p standard.

8. The communication device according to claim 7 , wherein
the first communication protocol is based on a standard of the 3 rd Generation Partnership Project.

9. The communication device according to claim 8 , wherein
the control information comprises synchronization information.

10. The communication device according to claim 1 , wherein
the first communication protocol is based on a standard of the 3 1 Generation Partnership Project.

11. The communication device according to claim 1 , wherein
the control information comprises synchronization information.

12. A system for use with a vehicle, comprising:
a server;
a communication device installed in the vehicle, the communication device comprising:
a first communication unit configured to communicate with the server via a first communication protocol, the first communication unit comprising a first interface for establishing the communication between the first communication unit and the server;
a second communication unit configured to communicate with at least one further vehicle via a second communication protocol, the second communication unit comprising a second interface for establishing the communication between the second communication unit and the at least one further vehicle, wherein
the first communication unit is configured to receive control information from the server for the second communication protocol, and to forward the control information to the second communication unit, and
the second communication unit is configured to perform, depending on the forwarded control information, at least one predetermined setting for communicating with the at least one further vehicle by way of the second communication protocol.

13. The system according to claim 12 , wherein
the second communication unit is configured to prepare measurement information on the second communication protocol and to forward the measurement information to the first communication unit, and
the first communication unit is configured to receive the measurement information forwarded by the second communication unit and to send the measurement information to the server.

14. The system according to claim 13 , wherein
the measurement information comprises channel measurement information which has been determined by the second communication unit by a channel measurement.

15. The system according to claim 14 , further comprising:
a control unit configured to receive the control information for the second communication protocol forwarded by the first communication unit and to forward the control information to the second communication unit.

16. The system according to claim 15 , wherein
the control unit is configured to receive the measurement information which has been forwarded by the second communication unit and to forward the measurement information to the first communication unit.

17. The system according to claim 16 , wherein
the first communication protocol is based on a standard of the 3 rd Generation Partnership Project.

18. The system according to claim 17 , wherein
the control information comprises synchronization information.
