Data delivery to devices on vehicles using multiple forward links
View Patent ↗Data content that is to be utilized, as a whole, at a target device on-board a vehicle is apportioned for delivery onto the vehicle via multiple forward links, each of which is included in a different frequency band and/or used a different protocol. A mapping or selection of a specific portion of the data content for a specific forward link may based on a data content type of the specific portion, as well as on other dynamic or static criteria. The target device may operate on the subsets of the data content as it receives each subset. Thus, time critical/foundational portions of the data content may be delivered using a faster forward link, larger elements of the data content may be delivered using a higher-bandwidth forward link, and/or portions of the data content requiring a higher degree of accuracy may be delivered using a more robust forward link, for example.

6. The method of claim 1 , wherein mapping the each portion of the requested content is further based on a size of a data stream in which the requested content is included.
7. The method of claim 1 , wherein mapping the each portion of the requested content is further based on at least one of: a respective current capacity of at least one of the plurality of forward links, a respective current availability of the at least one of the plurality of forward links, a respective transmission quality of the at least one of the plurality of forward links, an availability of a socket corresponding to one of the plurality of forward links, a delivery time requirement, or a dynamic resource allocation algorithm.
8. The method of claim 1 , wherein mapping the each portion of the requested content is performed at one or more of an application level, a packet level, or a stream level of a data stream in which the requested content is included.
9. The method of claim 1 , wherein mapping one or more portions of the requested content is based on a type of socket corresponding to at least one of the plurality of forward links.
10. The method of claim 1 , wherein causing the respective transmissions of the plurality of portions of the requested content to be sent to the in-flight vehicle using the respective forward links comprises:
causing a first transmission to be sent to the in-flight vehicle using a first forward link, the first forward link comprising at least one of: a satellite communication link, an air-to-ground (ATG) communication link configured to deliver data directly between the in-flight vehicle and terrestrial ground stations, a communication link operating over a frequency band allocated for use by a protocol corresponding to the IEEE 802.11 standard, a communication link supporting a broadband protocol, or a communication link supporting a terrestrial cellular communication protocol; and
causing a second transmission to be sent to the in-flight vehicle using a second forward link different than the first forward link.
11. A method of distributively delivering content to devices being transported by vehicles, the method comprising:
receiving, at a vehicle that is in-flight, a plurality of portions of a content that has been requested via a user interface of a device on-board the vehicle, and that is to be delivered to the device on-board the vehicle for display, as a whole, at the user interface of the device, each portion of the plurality of portions received via a respective forward link of a plurality of forward links, at least one of the respective forward links selected based on a respective content type of a corresponding portion of the requested content, and wherein a particular forward link included in the at least one of the respective forward links is selected based on one of a first type of data included within a first portion of the plurality of portions of the requested content or a second type of data included in a second portion of the plurality of portions of the requested content; and
causing the plurality of portions of the requested content to be delivered via an on-board wireless network to the device for display, as a whole, at the user interface of the device.
12. The method of claim 11 , wherein:
receiving, at the vehicle that is in-flight, the plurality of portions of the requested content comprises:
receiving the first portion of the requested content via the particular forward link, the particular forward link included in a first wireless communication link; and
