Quality framework for vehicle application data networks

A system for providing quality of experience (QoE) metrics to incoming application data transferred to a vehicle, comprising:

• a cloud-based dynamically updatable application QoE policy engine adapted to:
• measure key network performance indicators, including at least throughput, jitter, latency, packet drop rate, and signal noise ratio, by at least one of:
• link-level network status monitoring;
• and
• path-level network status monitoring;
• establish key application quality indicators, including at least application level bandwidth, application level delay, application level quality and application specific metrics;
• establish QoE metrics and prioritization criteria for incoming application data and to assign QoE policies to the vehicle;
• and
• a data controller within the vehicle adapted to receive QoE policies from the application QoE policy engine and enforce the QoE policies assigned;
• and
• wherein the data controller is adapted to;
• enforce the QoE policies assigned with an enhanced distributed control access (EDCA) algorithm adapted to use a network analysis module policy engine to prioritize incoming application data traffic received via IEEE 802.11 standard supported wireless LAN technology channels,
• enforce the QoE policies assigned with a resource block allocation and network slicing (RAN) algorithm adapted to use an application deliver network policy engine to analyze and prioritize incoming application data traffic received via cellular channels;
• and
• assign an appropriate portion of a total overall available bandwidth to different data streams of the incoming application data traffic.

• path-level network status monitoring;
• establishing, with the QoE policy engine, key application quality indicators, including at least application level bandwidth, application level delay, application level quality and application specific metrics;
• establishing, with the QoE policy engine, QoE metrics and prioritization criteria for incoming application data and assigning QoE policies to the vehicle;
• receiving, with a data controller within the vehicle, QoE policies from the application QoE policy engine;
• and
• enforcing, with the data controller, the QoE policies assigned.
