1. A method in which messages are transmitted to a vehicle from a multiplicity of data sources in a data network, comprising:
- supplying the messages directly to a server device of the data network;
assigning each of the messages to one of a plurality of predetermined message classes by the server device;
immediately transmitting to the vehicle messages in a first message class by the server device;

Abstract
A method ensures that message traffic runs smoothly during the transmission of messages from a plurality of data sources in a data network to a vehicle connected to the data network via a mobile radio interface. Messages are sent out to the vehicle from a plurality of data sources in a data network, in particular the Internet, and the messages are not delivered directly to the vehicle, but rather to a server device of the data network, where the messages are each assigned one of a plurality of predetermined message classes by the server device and messages of a first message class are immediately transferred to the vehicle by the server device, messages of a second message class are saved in the server device and messages of a third message class are deleted. A server device coupled to a data network works with the method.

16. A server device which can be coupled to a data network via a network interface to receive messages for a vehicle, comprising:
-
a decision making unit; to assign messages to one of a plurality of predetermined first, second and third message classes based in each case on properties of the vehicle and/or message type; and to delete messages in the third class; a transmitter; to immediately forward to the vehicle messages in the first message class; and to transmit to the vehicle a message packet containing a plurality of messages in the second message class; and a memory to buffer messages in the second message class, wherein after the messages in the second message class are buffered by the memory, the server device combines a plurality of messages in the second message class to form the message packet which the transmitter transmits to the vehicle. - View Dependent Claims (17, 18, 19, 20)
