QoS Gateway for OTT Application Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Over-the-top (OTT) applications on user devices often lack quality of service (QoS) control, leading to inconsistent and suboptimal user experiences due to reliance on external network infrastructure, which cannot guarantee service quality.
Innovation Solution
Implementing a Quality of Service (QoS) management system that allows users to request and apply QoS to OTT applications, involving authentication and policy enforcement through a QoS device, QOS-GW, and network elements like PCRF, to ensure better performance for voice, audio, and video applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If OTT applications use existing network infrastructure without QoS control, then network compatibility and ease of operation are improved, but service quality and reliability deteriorate
Solution Approach 1:
The patent introduces a QoS gateway as an intermediary component between the OTT application and the network infrastructure. This gateway establishes dedicated QoS channels that mediate traffic flow, ensuring that OTT applications receive guaranteed service quality while maintaining compatibility with existing network infrastructure. The gateway acts as a bridge that translates standard network traffic into QoS-controlled streams without requiring changes to the underlying network architecture.
2Reliability
If QoS management system is implemented with authentication and policy enforcement, then service quality and reliability are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The QoS gateway is designed as a multi-functional universal device that consolidates multiple QoS management functions into a single system. It simultaneously performs authentication, authorization, policy enforcement, traffic monitoring, and channel management. This universal approach reduces overall system complexity by eliminating the need for separate specialized components for each function, while still providing comprehensive QoS control.
Solution Approach 2:
The system implements continuous feedback mechanisms where the QoS gateway monitors traffic flow, service quality metrics, and policy compliance in real-time. Based on this feedback, the gateway dynamically adjusts QoS parameters, enforces policies, and manages authentication. This closed-loop control simplifies complex QoS management by using automated feedback-driven adjustments rather than requiring manual configuration and intervention for each scenario.

AI summary
A first network device receives an authentication request, from a second network device, to authenticate a user device and a first over-the-top application, stored on the user device, to determine whether to apply a level of quality of service to the first over-the-top application. The first network device authenticates the user device, based on the authentication requested. The first network device authenticates the first over-the-top application, based on the authentication request. The first network device sends an authentication result, based on the authentication of the user device and the first over-the-top application, to the second network device; and the second network device initiates, based on the authentication result, a process to apply a level of quality of service to information sent between the first over-the-top application and a provider associated with the first over-the-top application.
