Abstract: One general aspect includes a method of detecting vehicle movement, the method including: (a) measuring, via a controller, one or more signal variables as a first variable data set; (b) at some duration of time after the first variable data set is measured, via the controller, measuring the one or more signal variables as a second variable data set; (c) comparing, via the controller, the first and second variable data sets; (d) determining, via the controller, if substantial differences exist between the first and second variable data sets; (e) when it is determined that substantial differences exist between the first and second variable data sets, via the controller, generating a notification configured to indicate vehicle movement has been detected.

Abstract: A vehicle wireless unit and a method of operating the same. The vehicle wireless unit and method may be used to temporarily halt a non-interrupted data flow between the vehicle wireless unit and a cellular network over a first cellular link according to a first radio access technology (RAT), which purposely causes the vehicle wireless unit to enter an idle mode and results in the first cellular link being released. Once the first cellular link is released, the vehicle wireless unit and method may search for and, if found, establish a second cellular link with the cellular network according to a higher-order radio access technology (RAT). The vehicle wireless unit and method may be particularly useful with autonomous or semi-autonomous vehicles.
