Abstract

In one embodiment, a device identifies a predicted future location of a vehicle. The device uses a machine learning-based model to predict a dwell time for the vehicle at the predicted future location. The device determines, based on the predicted dwell time, whether the vehicle should associate with a wireless access point in the predicted future location. The device selects a particular wireless access point in the predicted future location for association, when the device determines that the vehicle should associate with a wireless access point in the predicted future location. The device initiates an association between the vehicle and the selected wireless access point, prior to the vehicle arriving at the predicted future location.

First claim

What is claimed is:

identifying, by a device, a predicted future location of a vehicle; using, by the device, a machine learning-based model to predict a dwell time for the vehicle at the predicted future location; determining, by the device and based on the predicted dwell time, whether the vehicle should associate with a wireless access point in the predicted future location; selecting, by the device, a particular wireless access point in the predicted future location for association, when the device determines that the vehicle should associate with a wireless access point in the predicted future location; and initiating, by the device, an association between the vehicle and the selected wireless access point, prior to the vehicle arriving at the predicted future location.

2 . The method as in claim 1 , wherein the selected wireless access point comprises a Wi-Fi hotspot, and wherein the device comprises a router for the vehicle.

3 . The method as in claim 1 , wherein selecting the particular wireless access point in the predicted future location for association comprises:
providing, by the device, one or more wireless access points in the predicted future location to a user interface; and receiving, at the device, a selection of the particular wireless access point via the user interface.

4 . The method as in claim 1 , wherein selecting the particular wireless access point in the predicted future location for association comprises:
assigning, by the device, scores to the wireless access points in the predicted future location based on one or more of: current loads of the wireless access points, radio frequency (RF) signal characteristics of the wireless access points, or supported communication protocols of the wireless access points.

5 . The method as in claim 1 , wherein initiating the association between the vehicle and the selected wireless access point, prior to the vehicle arriving at the predicted future location, comprises:
performing, by the device, authentication of the vehicle to the selected wireless access point, prior to the vehicle arriving at the predicted future location.

6 . The method as in claim 1 , wherein using the machine learning-based model to predict the dwell time for the vehicle at the predicted future location comprises:
using, by the device, a driving history of the vehicle and one or more physical features of the predicted future location as input to the machine learning-based model.

7 . The method as in claim 6 , wherein the one or more physical features of the predicted future location comprises at least one of: a traffic signal, a refueling station, or a drive-thru.

8 . The method as in claim 1 , wherein using the machine learning-based model to predict the dwell time for the vehicle at the predicted future location comprises:
assigning, by the device, the vehicle to one of a plurality of dwell time classifications, wherein each dwell time classification is associated with a different range of dwell times.

9 . The method as in claim 1 , wherein identifying the predicted future location of the vehicle comprises:
assessing, by the device, a current location of the vehicle using a history of travel of the vehicle.

10 . An apparatus, comprising:
one or more network interfaces to communicate with a network; a processor coupled to the network interfaces and configured to execute one or more processes; and a memory configured to store a process executable by the processor, the process when executed configured to:
identify a predicted future location of a vehicle;
use a machine learning-based model to predict a dwell time for the vehicle at the predicted future location;
