Abstract

A node of a cellular network detects entry of a vehicle-to-vehicle communication device into a cell of the cellular network. The node allocates resources to the vehicle-to-vehicle communication device, and sends channel information to the vehicle-to-vehicle communication device. The channel information can be included in a handover command to the vehicle-to-vehicle communication device. The channel information indicates the allocated resources. The vehicle-to-vehicle communication device uses the allocated resources for sending of vehicle-to-vehicle communication messages.

First claim

The invention claimed is:

1. A method for controlling vehicle-to-vehicle communication, the method comprising:
connecting, by a vehicle-to-vehicle (V2V) communication device associated with a first vehicle and using a first radio technology and a first radio interface, the V2V communication device associated with the first vehicle to a node servicing a first cell of an Intelligent Transport System (ITS) region having a plurality of cells that are part of a cellular network;
receiving, by the V2V communication device associated with the first vehicle, channel information from the cellular network, the channel information indicating a first resource which is allocated to the V2V communication device associated with the first vehicle for sending of V2V communication messages within the first cell;
determining, by the V2V communication device, that the first vehicle has entered a second cell;
applying the channel information to the second cell, wherein the second cell is another cell of the ITS region; and
transmitting, by the V2V communication device associated with the first vehicle, and using the channel information and a second radio technology different from the first radio technology and a second radio interface different from the first radio interface, at least one V2V communication message to a V2V communication device associated with a second vehicle within the second cell.

2. The method according to claim 1 , further comprising
monitoring, by the V2V communication device associated with the first vehicle, a second resource for receiving V2V communication messages, wherein the second resource is indicated by the channel information.

3. The method according to claim 1 ,
wherein the first radio technology comprises a radio technology selected from a Global System for Mobile communication (GSM) radio technology, a Universal Terrestrial Mobile Telecommunications System (UMTS), a Wideband Code Division Multiple Access (Wideband CDMA) radio technology, a WIMAX radio technology, and a 3GPP Service Architecture Evolution/Long Term Evolution (SAE/LTE) radio technology, and wherein the second radio technology different from the first radio technology is selected from an ad-hoc Wireless Local Area Network (WLAN) radio technology and a LTE Device-to-Device (D2D) technology.

4. The method according to claim 3 ,
wherein the first resource indicated in the channel information is located in a radio spectrum which is assigned to the first radio technology.

5. The method according to claim 1 ,
wherein the channel information is received by the V2V communication device associated with the first vehicle in a handover command from the cellular network.

6. A method for controlling vehicle-to-vehicle (V2V) communication, the method comprising:
detecting, by a node of a cellular network servicing an Intelligent Transport System (ITS) region having a plurality of cells, entry of a V2V communication device associated with a first vehicle into a first cell of the ITS region;
allocating, by the node, a first resource to the V2V communication device, the first resource being allocated for sending of V2V communication messages by the V2V communication device associated with the first vehicle while in any cell of the ITS region, wherein the V2V communication messages are to be sent using a first radio technology and a first radio interface, to a plurality of V2V communication devices associated with other vehicles; and
transmitting radio frequency (RF) signals, using a second radio technology different from the first radio technology, to a second radio interface of the V2V communication device associated with the first vehicle different from the first radio interface, channel information indicating the first resource.

7. The method according to claim 6 ,
wherein the channel information further indicates resources to be monitored by the V2V communication device associated with the first vehicle for receiving V2V communication messages from V2V communication devices associated with other vehicles.

8. The method according to claim 6 ,
wherein the second radio technology comprises a radio technology selected from a Global System for Mobile communication (GSM) radio technology, a Universal Terrestrial Mobile Telecommunications System (UMTS), a Wideband Code Division Multiple Access (Wideband CDMA) radio technology, a WIMAX radio technology, and a 3GPP Service Architecture Evolution/Long Term Evolution (SAE/LTE) radio technology, and wherein the first radio technology different from the second radio technology is selected from an ad-hoc Wireless Local Area Network (WLAN) radio technology and a LTE Device-to-Device (D2D) technology.

9. The method according to claim 8 ,
wherein the first resource indicated in the channel information is located in a radio spectrum which is assigned to the second radio technology.

10. The method according to claim 6 ,
wherein the first cell is a target cell of a handover from a source cell and the method further comprises:
preparing by the node a handover command to be sent to the V2V communication device; and
sending by the node the handover command in a handover preparation message to a node servicing the source cell.

11. A device for vehicle-to-vehicle (V2V) communication, the device comprising:
a first radio interface for communication with a cellular network using a first radio technology;
a second radio interface different from the first radio interface for vehicle-to-vehicle (V2V) communication using a second radio technology different from the first radio technology; and
at least one processor,
wherein the at least one processor is configured to:
receive, while in a first cell of an Intelligent Transport System (ITS) region having a plurality of cells and via the first radio interface, channel information from the cellular network, the channel information indicating first resources which are allocated to the device for V2V communication for sending of vehicle-to-vehicle communication messages using the second radio technology within the first cell; and
determine that the device has entered a second cell;
apply the channel information to the second cell, wherein the second cell is another cell of the ITS region; and
transmit, using the channel information and the second radio technology, and via the second radio interface, V2V communication messages within the second cell.

12. The device according to claim 11 ,
wherein the channel information further indicates second resources to be monitored by the device for V2V communication for receiving V2V communication messages using the second radio technology.

13. The device according to claim 11 ,
wherein the first radio technology comprises a radio technology selected from a Global System for Mobile communication (GSM) radio technology, a Universal Terrestrial Mobile Telecommunications System (UMTS), a Wideband Code Division Multiple Access (Wideband CDMA) radio technology, a WIMAX radio technology, and a 3GPP Service Architecture Evolution/Long Term Evolution (SAE/LTE) radio technology, and wherein the second radio technology different from the first radio technology is selected from an ad-hoc Wireless Local Area Network (WLAN) radio technology and a LTE Device-to-Device (D2D) technology.

14. The device according to claim 13 ,
wherein the first resources indicated in the channel information are located in a radio spectrum which is assigned to the first radio technology.

15. The device according to claim 11 ,
wherein the at least one processor is configured to receive the channel information in a handover command from the cell
