Content Provider Multipath Policy Steering

The patent introduces a Network Exposure Function (NEF) as an intermediary between the UE and network operators. The NEF receives multipath policy information from the UE and forwards it to the network operator, enabling centralized control while maintaining UE autonomy in making steering decisions. This mediator resolves the contradiction by allowing both local UE decisions and network operator control.

The patent creates a universal multipath policy framework that works across different device vendors and operating systems. By defining standardized policy structures and using the NEF as a vendor-agnostic interface, the solution enables content providers to enforce their preferred multipath policies regardless of the underlying device implementation, thus achieving universality while maintaining reliability.

The patent enables QUIC applications to self-enforce their multipath policies directly at the application level without requiring terminal or OS support. The application can independently declare its preferred multipath policy, and the NEF facilitates communication of this policy to the network operator, allowing the application to serve itself rather than depending on terminal infrastructure.

The patent implements a feedback mechanism where the UE declares its intended multipath policy to the network operator through the NEF. This allows the network operator to see what native multipath policies are being applied and adjust proxy deployment accordingly. The feedback loop ensures that proxies are used when appropriate while respecting native multipath implementations, optimizing proxy utilization efficiency.
