摘要
Concepts and technologies disclosed herein are directed to the optimization of over-the-air (“OTA”) file distribution for connected cars based upon a heuristic scheduling algorithm. A schedule provided by the heuristic scheduling algorithm is designed to distribute OTA data flow to connected cars over the network (geographically) and over a scheduling time horizon (timely), and is capable of reducing the negative impact of OTA file updates on overall wireless network performance. This schedule is created based upon historical statistics associated with connected car driving patterns and simulations of connected car-specific OTA traffic over the network. By leveraging connected cars that connect to different cells at different times based upon driving patterns, the heuristic scheduling algorithm is effective in reducing OTA impact on the network.

This application is a continuation of and claims priority to U.S. patent application Ser. No. 15/379,880, entitled “Optimization of Over-The-Air File Distribution for Connected Cars Based Upon a Heuristic Scheduling Algorithm,” filed Dec. 15, 2016, now U.S. Pat. No. 10,332,006, which is incorporated herein by reference in its entirety.
In recent years, mobile telecommunications operators have experienced a dramatic increase in traffic on their networks, and this trend will likely continue. This increase in traffic has been caused in part by the increased adoption of mobile devices such as smartphones and other mobile devices that rely on mobile telecommunications networks, and the migration of many customers from utilizing landline telecommunication services to utilizing mobile telecommunication services for their communications needs. To meet the demands of higher traffic and to improve the end user experience, mobile telecommunications operators are examining mechanisms by which to improve network efficiency, network capacity, and the end user experience, while keeping operational costs at a level conducive to maintaining competitive rates for the services they provide.
