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 hardware resources operating within the hardware resource layer 702 can be virtualized by one or more virtual machine monitors (“VMMs”) 714A-714K (also known as “hypervisors”; hereinafter “VMMs 714”) operating within the virtualization/control layer 704 to manage one or more virtual resources that reside in the virtual resource layer 706. The VMMs 714 can be or can include software, firmware, and/or hardware that alone or in combination with other software, firmware, and/or hardware, manages one or more virtual resources operating within the virtual resource layer 706.

The virtual resources operating within the virtual resource layer 706 can include abstractions of at least a portion of the compute resources 708, the memory resources 710, the other resources 712, or any combination thereof. These abstractions are referred to herein as virtual machines (“VMs”). In the illustrated embodiment, the virtual resource layer 706 includes VMs 716A-716N (hereinafter “VMs 716”). Each of the VMs 716 can execute one or more software applications, such as, for example, software application including instructions to implement, at least in part, one or more components of the network 114.

Turning now to FIG. 8, details of a network 800 are illustrated, according to an illustrative embodiment. The network 800 includes a cellular network 802, a packet data network 804, and a circuit switched network 806 (e.g., a public switched telephone network). The network 800 can include the network 114 illustrated and described with reference to FIG. 1.
