A method for supporting vehicular communications in a cellular network includes analyzing whether an incoming message is a vehicle data message or a base station control message. In the case that the incoming message is a base station control message of a specific base station: updating and/or storing the network operating parameters of the specific base station for controlling a transmission of selected vehicle data messages to the specific base station. In the case that the incoming message is a vehicle data message of a sending vehicle, determining at least one destination vehicle out of a provided and/or stored list of registered vehicles participating in the vehicular communication. The method also includes transmitting the vehicle data message to the at least one destination vehicle dependent on the at least one operating parameter of a respective receiving base station the at least one destination vehicle is connected to.

Methods, telematics server and base station for supporting vehicular communications in a cellular network

A method for broadcast service following for a vehicle includes a first step of continuously, or in given time intervals, estimating a signal quality and/or signal availability of the DAB service and/or the cellular network based broadcast service in a route section the vehicle is expected to reach in a given time span. The method also includes a second step of performing a handover from the DAB service to the corresponding cellular network based broadcast service dependent on the estimated signal quality and/or signal availability. The first step may depend on provided data base information. The first step may in addition, or in the alternative, depend on service information, which is included in a received DAB signal.
