Position-adaptive communication method

1. A position-adaptive communication method,

carried out by a communication control module of a mobile vehicle to set up and maintain a communication connection between a communication interface of a mobile vehicle, in particular a waterborne vessel and/or aircraft, and a communication interface of a remote station,

wherein the communication method is a packet-based communication method with a communication protocol which transmits useful data, backup data and possibly signaling data, et cetera as a data packet in a sequence in a communication frame, and wherein a transmission pause is provided between data packets and/or within the data packets, comprising the following steps:

determining position data of the vehicle with reference to a coordinate system;

receiving a movement data set from at least one remote station by means of a receiving device;

extracting position data from the received movement data and defining the position of the remote station in the global coordinate system;

determining a direction vector from the vehicle to the remote station;

determining a signal propagation time from the length of the direction vector;

adaptive matching of the transmission pause to the determined signal propagation time by a timer of the communication control module.

2. The communication method as claimed in claim 1 , characterized in that, in the case of a transmission pause provided by the communication protocol which is shorter than the determined signal propagation time, the transmission pause is made equal at least to the determined signal propagation time.

3. The communication method as claimed in claim 1 , characterized in that, in the case of a transmission pause provided by the communication protocol which is longer than the determined signal propagation time, the transmission pause is made equal at least to the determined signal propagation time.

4. The communication method as claimed in claim 1 , characterized in that the position data of the vehicle are extracted from data packets which have been received from a global satellite navigation system by means of a receiver provided on the vehicle.

5. The communication method as claimed in claim 1 , characterized in that movement data are transmitted cyclically by an automated identification system of the vehicle and/or of the remote station and are received by a receiving device of the vehicle.

6. The communication method as claimed in claim 1 , characterized in that an identifier is extracted from the received movement data and is stored as a remote station identifier in a database of the communication control module.

7. The communication method as claimed in claim 6 , characterized in that a group identifier is assigned to a selection of stored remote station identifiers and is stored.

8. The communication method as claimed in claim 6 , characterized in that the matching of the transmission pause ( 13 ) is carried out only in the case of remote stations for which a group identifier is stored in the database.

9. The communication method as claimed in claim 1 , characterized in that position data of at least one stationary remote station are stored in the database.

10. The communication method as claimed in claim 1 , characterized in that movement data of a plurality of remote stations are received and a direction vector is determined for each of these remote stations.

11. The communication method as claimed in claim 10 , characterized in that the signal propagation time is determined as the maximum of the lengths of the direction vectors.

12. The communication method as claimed in claim 1 , characterized in that the timer cyclically carries out the matching of the transmission pause.

13. The communication method as claimed in claim 1 , characterized in that the timer forms the transmission pause from the signal propagation time and a safety timespan.

14. The communication method as claimed in claim 1 , characterized in that a cell plan comprising coordinates of the coverage area is stored in the communication control module and the determined position data of the vehicle are compared by the communication control module with the stored coordinates of the coverage area and, if a vehicle position lies outside the coverage area, the communication interface of the vehicle is deactivated.

15. The communication method as claimed in claim 14 , characterized in that a cell plan is transmitted from the remote station via the communication connection to the vehicle and is stored by the communication control module.

16. The communication method as claimed in claim 1 , characterized in that the communication control module sets up a data connection via the communication connection to a processing service and transmits the position data of the vehicle and the remote station to the processing service and receives the signal propagation time and/or an updated communication protocol.

17. A communication protocol for use in a communication method as claimed in claim 1 , comprising, in a temporally defined sequence, useful data, signaling data, backup data, et cetera, and wherein a transmission pause is provided between data packets and/or within the data packets, said communication protocol being executed by a communication control module, characterized in that the communication control module has a timer which is designed to influence the transmission pause said timer having a signal input at which a propagation time signal is present, said propagation time signal serving as a basis for exerting the influence.

18. The communication protocol as claimed in claim 17 , characterized in that the communication protocol is formed as one of the protocols of the CSMA/CA, WiMAX and LTE group.
