User-Triggered QoS Boost via URSP Rules for App Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks struggle to reliably assign QoS flows to applications due to imperfect network-side detection, especially when applications are routed through tunnels, VPNs, or using protocols like QUIC, leading to suboptimal performance.
Innovation Solution
A user equipment (UE) downloads an application from a network operator that allows users to select and pay for a temporary performance increase, triggering network adjustments to provide enhanced QoS metrics like speed, latency, or jitter through URSP rules and network flow provisioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If network-side application detection is used to assign QoS flows, then automated QoS assignment is achieved, but detection reliability deteriorates when applications are routed through tunnels, VPNs, or QUIC protocols
Solution Approach 1:
The patent introduces an intermediary application layer between the user and the network that handles QoS requests. Instead of relying on network-side detection, the user equipment (UE) runs an application that communicates QoS requirements directly to the network through standardized interfaces, bypassing the detection reliability issue while maintaining automated assignment.
Solution Approach 2:
The patent inverts the traditional approach by shifting the detection and request initiation from the network side to the user equipment side. Rather than the network detecting applications and assigning QoS, the user's application explicitly requests QoS enhancements, reversing the control direction and eliminating detection failures.
2Speed
If temporary performance increase is provided through network flow provisioning, then application performance is improved, but network complexity increases due to URSP rules and flow management
Solution Approach 1:
The patent creates a universal application layer component that handles multiple QoS-related functions: detecting performance needs, formulating requests, managing URSP rules, and coordinating with network entities. This multi-functional approach consolidates complexity into a standardized interface rather than requiring complex point-to-point solutions.
Solution Approach 2:
The patent manages network complexity by dynamically adjusting QoS parameters (such as priority levels, bandwidth allocations, and latency requirements) through standardized modification requests. Instead of creating permanent complex configurations, the system changes parameters temporarily based on user needs, then reverts or updates them systematically.

AI summary
In some implementations, a network device may receive an indication that a user equipment (UE) satisfied one or more conditions to obtain a temporary performance increase for wireless traffic. The network device may store information associating a wireless network subscription of the UE with the temporary performance increase based on the indication. The network device may receive a request from the UE to activate the temporary performance increase for wireless traffic associated with an application. The network device may provision a wireless network flow associated with the temporary performance increase based on the request. The network device may send information to configure one or more UE route selection policy (URSP) rules to the UE, wherein the one or more URSP rules include one or more parameters that enable the UE to route the wireless traffic associated with the application over the wireless network flow associated with the temporary performance increase.
