A method of transmitting a message is disclosed, wherein the method is for a vehicle-to-vehicle communication enabled device adapted to operate in accordance with a vehicle-to-vehicle communication protocol and in accordance with a cellular communication protocol for communication with a wireless communication network. The method comprises determining (110) a geographical position of the vehicle-to-vehicle communication enabled device and determining (150), based on the determined geographical position, whether at least one direction extending from the determined geographical position lacks other vehicle-to-vehicle communication enabled devices for reception of the message. If at least one direction lacks other vehicle-to-vehicle communication enabled devices for reception of the message, the method comprises transmitting (170) a report to a network node of the wireless communication network, wherein the report indicates the message. Corresponding computer program product, arrangement and communication device are also disclosed. This method ensures that safety relevant messages are always delivered to all relevant V2V enabled devices, even if the device density is too low, in that it bridges the gap by using the cellular network as a backup. |
