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.
