Abstract

A vehicle wireless network access system includes a wireless connection switch disposed within a vehicle and configured to, in response to receiving a data transfer request, establish a wireless connection with one of a plurality of network links according to a prioritization of the network links that is based on a speed of the vehicle and an expected path of travel of the vehicle relative to the network links.

Claims

1. A vehicle system comprising:

a network switch disposed within a vehicle and configured to, in response to a data transfer request, establish a wireless connection with one of a plurality of network links according to a prioritization of the network links based on a combination of (i) network quality metrics required for a type of the request, (ii) a speed of the vehicle, and (iii) an expected path of travel of the vehicle relative to the network links.

2. The system of claim 1, wherein the prioritization is further based on historical data indicative of duration of connection to at least one of the network links.

3. The system of claim 1, wherein the prioritization is further based on network quality metrics including signal strength, maximum signal range, transmission error rate, latency, data throughput, QoS, reliability, or data transmission cost.

4. The system of claim 1, wherein the prioritization is further based on an estimated duration for which the vehicle will remain at a location.

5. The system of claim 1, wherein the wireless connection switch is further configured to perform the prioritization in response to detecting an on-location network link associated with an upcoming location of the vehicle.

6. The system of claim 5, wherein the upcoming location of the vehicle is based on a calendar entry of a mobile device.

7. The system of claim 5, wherein the upcoming location of the vehicle is based on a historic navigation route.

8. The system of claim 1 further comprising a vehicle gateway module, wherein the wireless connection switch is integrated within the vehicle gateway module.

18. The vehicle wireless network access system of claim 1, wherein the type of the request includes making a voice call, downloading digital media, streaming digital media, performing data logging, conducting data analytics, checking a calendar entry, or analyzing a navigation route.

20. The vehicle system of claim 1, wherein the speed of the vehicle is greater than 5 miles-per-hour.

9. A method for a vehicle comprising:

in response to receiving a data transfer request, establishing a wireless connection with one of a plurality of network links according to a prioritization of the network links based on a combination of (i) network quality metrics required for a type of the request, (ii) a speed of the vehicle, and (iii) an expected path of travel of the vehicle relative to the network links.

10. The method of claim 9, wherein the prioritization is further based on historical data indicative of duration of connection to at least one of the network links.

11. The method of claim 9, wherein the prioritization is further based on network quality metrics including signal strength, maximum signal range, transmission error rate, latency, data throughput, QoS, reliability, or data transmission cost.

12. The method of claim 9, wherein the prioritization is further based on a location of the vehicle.

13. The method of claim 9, wherein the prioritization is further based on an estimated duration for which the vehicle will remain at a location.

14. The method of claim 9, further comprising performing the prioritization in response to detecting an on-location network link associated with an upcoming location of the vehicle.

15. The method of claim 14, wherein the upcoming location of the vehicle is based on a calendar entry of a mobile device.

16. The method of claim 14, wherein the upcoming location of the vehicle is based on a historic navigation route.

19. The method of claim 9, wherein the type of the request includes making a voice call, downloading digital media, streaming digital media, performing data logging, conducting data analytics, checking a calendar entry, or analyzing a navigation route.

17. A method for a vehicle comprising:

in response to receiving a data transfer request,

identifying first and second network links, the first network link having a lower signal strength and being located further away from the vehicle than the second network link, and

establishing a wireless connection with the first network link and not the second network link based on a combination of (i) network quality metrics required for a type of the request, (ii) vehicle speed, and (iii) an expected path of travel of the vehicle toward the first network link and away from the second network link.
