Embodiment Construction

[0011] As required, detailed embodiments of the invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0012] A mobile device, such as a smartphone or a telematics control unit (TCU) of a connected vehicle, acts as a node in the network. Mobile devices generally require a packet switched (PS) data connection over a cellular network. Wireless communication is inherently unreliable due to the dynamic nature caused by environmental disturbances. Therefore, the mobile device's connection to the ...

Abstract

A telematics controller is programmed to identify a location responsive to detecting a failed data call from a vehicle, and if the location is within a geographic boundary of a failure zone within a cellular tower region and a cause of the failure matches a recorded cause for the failure zone, initiate data throttling until the vehicle moved outside of the geographic boundary.

Description

technical field [0001] Aspects of the present disclosure relate generally to connection history based retry throttling. Background technique [0002] When a data connection fails, the user device may attempt to retry the connection. In many cases, however, the connection may fail again for the same reason that the initial connection attempt failed. Retry throttling can be used to throttle retry attempts when a large number of requests fail and retries are unsuccessful. Contents of the invention [0003] In one or more illustrative examples, a vehicle includes a telematics controller programmed to identify a location in response to detecting a failed data call from the vehicle, and if the If the location is within a geographic boundary of a failure zone within a cell tower area and the cause of the failure matches a cause recorded for the failure zone, data throttling is initiated until the vehicle moves outside of the geographic boundary. [0004] In one or more illustr...
