Abstract

Systems and methods for providing a stable communication between a vehicle'"'"'s on-board connectivity layer include at least one vehicle located communication node and at least one vehicle associatable communication node, and an off-board connectivity layer including at least one remote system located communication node, wherein each communication node communicates with at least one other communication node over a communication connection, and in case the communication connection to the at least one communication node is disturbed or interrupted, a communication connection to another communication node is established.

Claims

1. Method for providing a stable and tamper proof communication between a vehicle and a corresponding vehicle'"'"'s remote system and/or for providing a stable and tamper proof communication between at least one vehicle related unit and a corresponding vehicle related unit'"'"'s remote system,

wherein the vehicle comprises at least one vehicle located communication node and the vehicle'"'"'s remote system comprises at least one vehicle'"'"'s remote system communication node for connecting the vehicle and the vehicle'"'"'s remote system via a vertical communication connection, and

wherein the at least one vehicle related unit comprises at least one vehicle associable communication node and the remote system corresponding to the vehicle related unit comprises at least one remote system communication node for connecting the at least one vehicle related unit and the remote system of the vehicle related unit via another vertical communication connection,

the method comprising the steps of:

establishing an on-board connectivity layer comprising the at least one vehicle located communication node and the at least one vehicle associable communication node,

the step of establishing the on-board connectivity layer comprising;

i. transmitting by means of an initializing communication node an Invitation Request (IR) for forming the onboard connectivity layer to all communication nodes;

ii. re-transmitting a Response Message (RM) comprising information on an acceptance of the Invitation Request (IR) to the initializing communication node; and

iii. transmitting an On-board Connectivity Layer Established Message (OnCLEM) from all on-board connectivity layer communication nodes to their remote system communication nodes;

providing horizontal communication connections between the communication nodes of the on-board connectivity layer; and

bypassing a disturbed or interrupted vertical communication connection by using the vertical communication connection of the at least one other communication node of the on-board connectivity layer connected by the horizontal communication connection to the on-board communication node having the disturbed or interrupted vertical default communication connection.

2. Method according to claim 1, wherein step i is performed by transmitting the invitation request (IR) to the communication nodes which are intended to be comprised in the vehicle'"'"'s on-board connectivity layer and forwarding by means of the receiving on-board communication nodes the Invitation Request (IR) to the remote system communication nodes corresponding to the receiving on-board communication nodes.

3. Method according to claim 1, wherein step ii is performed by retransmitting the response message (RM) to the initializing communication node via the corresponding onboard communication nodes.

4. Method according to claim 1, wherein the method further comprises the step of establishing an off-board connectivity layer comprising the remote system communication nodes.

5. Method according to claim 4, wherein the step for establishing an off-board connectivity layer comprises at least one of the following steps:

i. Transmitting an Off-board Invitation Request (Off-IR) to all remote system communication nodes;

ii. Transmitting an Off-board communication setup message (Off-SM) to all remote system communication nodes which are intended to be comprised in the off-board connectivity layer;

iii. Receiving an Off-board Response Message (Off-RM);

iv. Transmitting an Off-board Connectivity Layer Established Message (OffCLEM) from all remote system communication nodes to their corresponding on-board connectivity layer communication nodes.

6. Method according to claim 1, wherein the method further comprises the step of exchanging encryption keys (EKM) between the communication nodes.

7. Method according to claim 1, wherein the method further comprises the step of exchanging at least one communication node address (eNA) between the communication nodes.

8. Method according to claim 1, further comprising the step of detecting available communication nodes.

9. Method according to claim 1, further comprising the step of transmitting to all communication nodes data comprising information regarding disturbed or interrupted communication connections.

10. Method according to claim 1, further comprising the step of manually or automatically repeating at least one of the method steps on certain time intervals and/or on a per event basis.

11. Method according to claim 1, further comprising the step of checking and verifying the availability of the communication nodes and/or of the communication connections.

12. Method according to claim 10, further comprising the step of detecting a change in the configuration of the connectivity layers.

13. Method according to claim 12, further comprising the step of reporting a non-authorized change in the configuration of the connectivity layer in case the configurations differ and there is no confirmation of the change.

14. Method according to claim 1, wherein the at least one vehicle communication node is comprised in a truck.

15. Method according to claim 1, wherein the at least one vehicle associable communication node is comprised in a trailer, and/or a cargo, and/or a driver related device, and/or a fifth wheel control unit.

16. Method according to claim 14, wherein the on-board system'"'"'s and/or the sensor networks comprise at least one integral and/or at least one nomadic device such as a video camera system.

17. Method according to claim 1, wherein the at least one vehicle'"'"'s remote system communication node is comprised in a back office system of a vehicle company, and the at least one remote system communication node of the vehicle related unit'"'"'s remote system is comprised in a back office system of a trailer company, and/or a back office of a cargo company, and/or a back office system of an end user, and/or an emergency call centre, and/or a security company.

18. Method according to claim 1, wherein the vertical and/or horizontal communication connection communicate based on a unicast and/or a multicast and/or a broadcast and/or an anycast routing scheme.

19. Method according to claim 1, wherein the vertical and/or horizontal communication connection is bi-directional.

20. Method according to claim 1, wherein the communication connection is an encrypted and/or an authenticated communication connection.

21. Vehicle comprising a vehicle located communication node which is adapted or adaptable to perform a method according to claim 1.

22. Vehicle related unit comprising a vehicle associable communication node which is adapted or adaptable to perform a method according to claim 1, wherein the vehicle related unit is a trailer, a cargo and/or a driver'"'"'s handheld device.

23. Communication node which is adapted or adaptable to be part of a vehicle and wherein the communication node is further adapted to perform a method according to claim 1.

24. A computer programmed with a computer program comprising a software code adapted or adaptable to perform a method or for use in a method according to claim 1.

25. A non-transitory computer program product stored on a computer readable medium, comprising a software code for use in a method according to claim 1.
