Abstract

A method and an apparatus transmit data between a first communications network of a first track-guided vehicle unit and a second communications network of a second track-guided vehicle unit. In order to ensure flexible data transmission between the first and second communications networks, the data between the first and second vehicle units are transmitted via a terrestrial data device.

First claim

1 - 15 . (canceled)

16 . A method for transmitting data between a first communications network of a first rail-bound vehicle unit and a second communications network of a second rail-bound vehicle unit, which comprises the steps of:
transmitting the data between the first rail-bound vehicle unit and the second rail-bound vehicle unit via a land-based data facility.

17 . The method according to claim 16 , which further comprises transmitting the data between the first communications network and the second communications network via a superordinate communications network.

18 . The method according to claim 17 , wherein:
the first communications network extends over the first rail-bound vehicle unit; the second communications network extends over the second rail-bound vehicle unit; and/or the superordinate communications network extends over a rail-bound vehicle that contains the first rail-bound vehicle unit and the second rail-bound vehicle unit.

19 . The method according to claim 18 , which further comprises transmitting the data between the first rail-bound vehicle unit and the second rail-bound vehicle unit via the land-based data facility by means of the superordinate communications network.

20 . The method according to claim 16 , which further comprises transmitting the data in a wireless manner between:
the first rail-bound vehicle unit or the second rail-bound vehicle unit; and the land-based data facility.

21 . The method according to claim 20 , wherein the data transmitted in the wireless manner is transmitted using a mobile radio standard.

22 . The method according to claim 16 , which further comprises transmitting the data in an encrypted manner between:
the first rail-bound vehicle unit or the second rail-bound vehicle unit; and the land-based data facility.

23 . The method according to claim 16 , which further comprises:
sending a request for data, originating from the second communications network, to the land-based data facility; forwarding the request from the land-based data facility to the first communications network; and providing requested data by the first communications network in response to the request.

24 . The method according to claim 16 , wherein:
the first rail-bound vehicle unit and the second rail-bound vehicle unit are part of a fleet of rail-bound vehicles; and/or the first rail-bound vehicle unit and the second rail-bound vehicle unit are part of a common rail-bound vehicle.

25 . The method according to claim 16 , wherein the data that is provided for a transmission between a first control network as the first communications network and a second control network as the second communications network are transmitted in a prioritized manner between:
the first rail-bound vehicle unit and the land-based data facility; or the second rail-bound vehicle unit and the land-based data facility.

26 . An apparatus for transmitting data, the apparatus comprising:
a first communications network for a first rail-bound vehicle unit; a second communications network for a second rail-bound vehicle unit; and a land-based data facility, the apparatus embodied so as to transmit the data between the first rail-bound vehicle unit and the second rail-bound vehicle unit via said land-based data facility.

27 . The apparatus according to claim 26 , further comprising a superordinate communications network embodied so as to transmit the data between said first communications network and said second communications network.

28 . The apparatus according to claim 27 , wherein:
said first communications network extends over the first rail-bound vehicle unit; said second communications network extends over the second rail-bound vehicle unit; and/or said superordinate communications network extends over a rail-bound vehicle that includes the first rail-bound vehicle unit and the second rail-bound vehicle unit.

29 . A communications network for transmitting data between a first communications network of a first rail-bound vehicle unit and a second communications network of a second rail-bound vehicle unit, the communications network comprising:
a land-based data facility; a first data-technology connection between the first rail-bound vehicle unit and said land-based data facility; a second data-technology connection between the second rail-bound vehicle unit and said land-based data facility; and a superordinate communications network for transmitting data between the first communications network and the second communications network on a path via said first data-technology connection, said land-based data facility and said second data-technology connection.

30 . A method of using a data-technology connection embodied so as to transmit data between a first rail-bound vehicle unit and/or a second rail-bound vehicle unit and a land-based data facility, which comprises the steps of:
transmitting the data between a first communications network of the first rail-bound vehicle unit and a second communications network of the second rail-bound vehicle unit.
