Abstract

Remotely performed maintenance of a transportation unit such as an aircraft is disclosed, wherein the maintenance is performed utilizing a networked environment. In one implementation, a first network, located within the mobile transportation unit, is accessed from a second network, located externally to the mobile transportation unit. Having remotely assessed the first network, communication with one or more assets of the mobile transportation unit, which are connected to the first network, is possible. Maintenance operations are then performed by exchanging data and commands with the assets of the mobile transportation unit.

Claims

1. A method to perform maintenance operations on one or more assets of a mobile transportation unit, comprising:

accessing a first network located on the mobile transportation unit from a terminal on a second network external to the mobile transportation unit wherein

the first network provides connectivity between multiple systems on the mobile transportation unit which operate according to disparate communication protocols, and

the second network is a ground-based network;

establishing a communication connection between the terminal on the second network and at least one of the one or more assets of the mobile transportation unit connected to the first network, wherein the communication connection enables the terminal to communicate directly with the at least one of the one or more assets of the mobile transportation unit; and

performing maintenance operations by sending commands from the terminal directly to the one or more assets, wherein;

the first network comprises an open networking data domain which provides connectivity to multiple networking domains aboard the mobile transportation unit; and

the open networking data domain maintains a table identifying network assets, wherein the table is configured based on an XML schema including an address and security attributes of each asset, and the open networking data domain utilizes address information from the table to enable establishing a communication connection between the terminal on the second network and at least one of the one or more assets of the mobile transportation unit.

2. The method of claim 1, wherein:

the mobile transportation unit is an aircraft;

the first network is coupled to a maintenance domain; and

the second network is the Internet.

3. The method of claim 1, wherein accessing the first network comprises using a security protocol configured to allow only authorized persons to access the first network.

4. The method of claim 1, wherein accessing the first network comprises one or more persons accessing the first network at the same time to perform maintenance operations on the mobile transportation unit.

5. The method of claim 1, wherein performing the maintenance operations comprises maintenance performed while the mobile transportation unit is stationary, in motion, on the ground or in the air.

6. The method of claim 1, wherein performing the maintenance operations is done while the mobile transportation unit is being assembled.

7. The method of claim 1, wherein performing the maintenance operations comprises:

receiving data from the one or more assets of the mobile transportation unit regarding status of the one or more assets; and

reconfiguring the one or more assets based on the data received.

8. The method of claim 1, wherein the open networking data domain comprises an internet protocol (IP) router.

9. The method of claim 1, further comprising:

receiving, in a remote maintenance support base, a report of a fault in one or more assets of the mobile transportation unit; and

launching, in the remote maintenance support base, a query to the one or more assets of the mobile transportation unit which generated the fault.
