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.

說明書

The illustrated cellular network 802 is shown in communication with the packet data network 804 and a circuit switched network 806, though it should be appreciated that this is not necessarily the case. One or more Internet-capable devices 810, for example, a PC, a laptop, a portable device, or another suitable device, can communicate with one or more cellular networks 802, and devices connected thereto, through the packet data network 804. It also should be appreciated that the Internet-capable device 810 can communicate with the packet data network 804 through the circuit switched network 806, the cellular network 802, and/or via other networks (not illustrated).

As illustrated, a communications device 812, for example, a telephone, facsimile machine, modem, computer, or the like, can be in communication with the circuit switched network 806, and therethrough to the packet data network 804 and/or the cellular network 802. It should be appreciated that the communications device 812 can be an Internet-capable device, and can be substantially similar to the Internet-capable device 810.
