Abstract

According to the invention, in a transfer of data (1) to at least one mobile unit the data (1) are provided with an identifier (7) that assigns the data (1) to the at least one mobile unit. The data (1) are assembled into a data stream (20) receivable by a multitude of mobile units, which is transmitted by means of at least one transmitting device (8) via at least one transmission path (22). At the mobile unit (23) end the data stream is received by means of at least one receiving device (9) and the data (1) are filtered from the received data stream (20) on the basis of the identifier (7).

Claims

1. Method of transferring data (1) to at least one mobile unit (23), characterized by the steps:

labelling of the data (1) with an identifier (7) that assigns the data (1) to the at least one mobile unit (23);

providing a data stream (20) which comprises the labelled data (1) and is receivable by a multitude of mobile units (23);

transmitting the data stream (20) by means of at least one transmission device (8) via at least one transmission path (22);

receiving the data stream (20) by means of at least one receiving device (9) of the at least one mobile unit (23); and

filtering of the labelled data (1) on the basis of the identifier (7) from the received data stream in the at least one mobile unit (23).

2. Method according to claim 1,

characterized in that

the data (1) to be transferred are encrypted and that the received data are decrypted in the at least one mobile unit (23).

3. Method according to claim 1 or 2,

characterized in that

the data stream (20) comprises transmission units which are labelled with an identifier (7) and are sent out repeatedly, and that in the at least one mobile unit (23) the data (1) are reassembled from the transmission units which are filtered from the data stream (20) on the basis of their identifier (7).

4. Method according to claim 3,

characterized in that

the data stream (20) with the transmission units provided with the identifier (7) is transmitted by a multitude of transmitting devices (8), wherein the receiving device (9) of the at least one mobile unit (23) is suited to receive the transmission units transmitted by various transmitting devices (8).

5. Method according to claim 4,

characterized in that

the data stream (20) is transmitted via multiple transmission paths (22) and that the at least one mobile unit (23) comprises multiple receiving devices (9), which are suited to receive the data stream (20) with the transmission units provided with the identifier (7) via one of the transmission paths (22), respectively.

6. Method according to any one of the preceding Claims,

characterized in that

the at least one transmission path (22) comprises a short-range wireless connection.

7. Method according to any one of the preceding Claims,

characterized in that

the at least one transmission path (22) comprises a long-range wireless connection.

8. Method according to any one of the preceding Claims,

characterized in that

the at least one transmission path (22) comprises a wired connection.

9. Method according to any one of the preceding Claims,

characterized in that

the identifier (7) assigns the data (1) to multiple mobile units (23).

10. Method according to any one of the preceding Claims,

characterized in that

upon filtering the data (1) from the data stream (20) the data (1) which are assigned to the at least one mobile unit (23) on the basis of the identifier (7) are stored while other data (1) from the data stream are discarded.

11. Method according to any one of the preceding Claims,

characterized in that

the data stream (20) comprises data which are to be transferred to at least one further mobile unit (23) and are assigned to the at least one further mobile unit (23) with a further identifier (7).

12. Method according to any one of the preceding Claims,

characterized in that

the at least one mobile unit (23) is arranged in a motor vehicle and that the data (1) of the data stream (20) comprise operating data of the motor vehicle.

15. Device according to claim 13 or 14,

characterized in that

the device is designed to implement the method according to any one of claims 1 to 12.

17. System according to claim 16

characterized in that

the system is designed to implement the method according to any one of claims 1 to 12.

13. Device for transferring data to at least one mobile unit,

characterized by

labelling means (5) for the labelling of the data (1) with an identifier (7) which assigns the data (1) to the at least one mobile unit (23),

data processing means (2, 3, 6) which are suited for establishing a data stream (20) comprising the labelled data (1), and

transmitting means (8) which transmit the data stream (20) via at least one transmission path (22).

16. System for transferring data (1) to at least one mobile unit (23),

characterized by

at least one device (21) for transferring data pursuant to claim 13 and at least one device for receiving data in a mobile unit (23) pursuant to claim 14.

14. Device for receiving data in a mobile unit (23),

characterized by

receiving means (9) for receiving a data stream (20), and

filter means (11) for filtering data (1) from the data stream (20) on the basis of an identifier (7) which assigns the data (1) to the mobile unit (23).

18. Motor vehicle having a mobile unit (23) with a device pursuant to claim 14.
