Abstract

According to one aspect, a method includes identifying a first signal, which carries or otherwise includes data, to be provided to a system by a vehicle. The method includes determining a first amount of bandwidth, the first amount of bandwidth being associated with the signal, determining a second amount of bandwidth, the second amount of bandwidth being an available bandwidth associated with a plurality of modems included on the vehicle to enable the vehicle to communicate with the system, and dividing the first signal into a first plurality of portions based at least on the first amount of bandwidth and the second amount of bandwidth. The first plurality of portions is provided to the plurality of modems for transmission from the vehicle to the system, and is transmitted to the system using the plurality of modems and a plurality of channels associated with the plurality of modems.

First claim

What is claimed is:

1. A method comprising:
identifying a first signal to be provided to a teleoperations system by a vehicle, wherein the first signal includes data, the vehicle configured to operate autonomously or semi-autonomously, the teleoperations system being configured to remotely operate the vehicle;
determining a first amount of bandwidth, the first amount of bandwidth being associated with the first signal;
determining a second amount of bandwidth, the second amount of bandwidth associated with a plurality of modems, the plurality of modems being included on the vehicle to enable the vehicle to communicate with the system, the plurality of modems being associated with a plurality of service providers, wherein the second amount of bandwidth is an approximately total amount of available bandwidth associated with the plurality of modems;
verifying whether the second amount of bandwidth is sufficient to transmit the first signal;
upon verifying that the second amount of bandwidth is sufficient to transmit the first signal, dividing the first signal into a first plurality of portions based at least on the first amount of bandwidth and the second amount bandwidth;
providing the first plurality of portions to the plurality of modems for transmission from the vehicle to the system; and
transmitting the first plurality of portions to the system using the plurality of modems and a plurality of channels, the plurality of channels being associated with the plurality of modems.

2. The method of claim 1 further including:
determining whether an issue associated with a first channel of the plurality of channels and a first modem of the plurality of modems is identified;
when it is determined that there is the issue associated with the first modem, reallocating the first signal, wherein reallocating the first signal includes dividing the first signal into a second plurality of portions, the second plurality of portions including a first portion allocated to the first modem, the first portion being smaller than other portions in the second plurality of portions;
providing the second plurality of portions to the plurality of modems for transmission from the vehicle to the system; and
transmitting the second plurality of portions to the system using the plurality of modems and the plurality of channels.

3. The method of claim 2 further including:
determining whether the issue associated with the first channel and the first modem is resolved;
when it is determined that the issue is resolved, reallocating the first signal, wherein reallocating the first signal includes dividing the first signal into a third plurality of portions;
providing the third plurality of portions to the plurality of modems for transmission from the vehicle to the system; and
transmitting the third plurality of portions to the system using the plurality of modems and the plurality of channels.

4. The method of claim 3 wherein determining whether the issue associated with the first channel and the first modem is resolved includes determining whether an acknowledgement (ACK) is obtained on the first channel from the system, wherein when the ACK is obtained it is determined that the issue is resolved.

5. The method of claim 2 wherein determining whether the issue associated with the first channel of the plurality of channels and the first modem of the plurality of modems is identified includes determining whether an acknowledgement (ACK) is obtained on the first channel from the system in response to the transmitted first plurality of portions, wherein when the ACK is not obtained, it is determined that there is the issue.

6. The method of claim 1 wherein the issue is a latency issue.

7. The method of claim 1 wherein the data includes a frame, the frame including a frame identifier (ID) and a payload, and wherein dividing the first signal into a first plurality of portions includes dividing the payload, wherein each portion of the first plurality of portions includes the frame ID.

8. The method of claim 1 wherein each portion of the first plurality of portions is approximately equal in size, and wherein each modem of the plurality of modems has approximately an equal amount of allocated bandwidth.

9. The method of claim 1 wherein the plurality of modems includes at least a first modem, a second modem, a third modem, and a fourth modem, wherein the first modem is associated with a first service provider of the plurality of service providers, the second modem is associated with a second service provider of the plurality of service providers, the third modem is associated with a third service provider of the plurality of service providers, and the fourth modem is associated with a fourth service provider of the plurality of service providers.

10. The method of claim 1 wherein the vehicle includes at least one sensor, and wherein identifying the first signal includes obtaining the data from the at least one sensor.

11. A vehicle comprising:
at least one sensor, the at least one sensor configured to capture data associated with the vehicle;
a plurality of modems, the plurality of modems being associated with a plurality of channels, wherein each modem of the plurality of modems is configured to allow the vehicle to communicate wirelessly with a teleoperations system over an associated channel of the plurality of channels;
an allocation arrangement, the allocation arrangement configured to allocate a signal that includes the data for transmission to the teleoperations system, wherein the allocation arrangement is configured to allocate the signal by dividing the signal into a first plurality of portions and wherein the plurality of modems is arranged to provide the first plurality of portions to the plurality of channels for transmission to the teleoperations system; and
an assessment arrangement, the assessment arrangement configured to determine when a first modem of the plurality of modems has a performance issue, wherein the allocation arrangement is configured to reallocate the signal when it is determined that the first modem has the performance issue.

12. The vehicle of claim 11 wherein the allocation arrangement is configured to reallocate the signal by dividing the signal into a second plurality of portions that includes a first portion allocated to the first modem, the first portion being smaller than at least a second portion of the second plurality of portions.

13. The vehicle of claim 11 wherein the allocation arrangement is configured to allocate the signal based on an overall available bandwidth associated with the plurality of modems.

14. The vehicle of claim 13 wherein the allocation arrangement is still further configured to allocate the signal based on a bandwidth associated with the signal.

15. The vehicle of claim 11 wherein the assessment arrangement is configured to determine when the first modem of the plurality of modems has a performance issue by determining whether an acknowledgement has been obtained on a first channel of the plurality of channels from the teleoperations system.

16. The vehicle of claim 11 wherein the plurality of modems includes a second modem, the first modem being associated with a first service provider, the second modem being associated with a second service provider.

17. The vehicle of claim 11 wherein the data includes a plurality of frames, each frame of the plurality of frames having a frame identifier (ID), and wherein each portion of the first plurality of portions includes portions of a first frame of the plurality of frames and the frame
