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.

說(shuō)明書

The RAN 108 can provide the user device 104 and the connected car 106 access to the network 114 over which to communicate with an OTA file distribution system 116. The OTA file distribution system 116 is utilized to implement aspects of the concepts and technologies described herein. The illustrated OTA file distribution system 116 encompasses several components, each of which may be combined into a single system as shown, or may be implemented as separate components capable of communicating together to share information. The OTA file distribution system 116 can include any hardware, software, firmware, or some combination thereof in any configuration to implement aspects of the concept and technologies disclosed herein. For example, the OTA distribution system 116, or one or more components thereof, can be implemented, at least in part, on a computer system, such as on an example computer system 500 shown in FIG. 5. Alternatively, the OTA distribution system 116, or one or more components thereof, can be implemented, at least in part, on an example system virtualization platform 700 shown in FIG. 7.
