OTT Application QoS via Native Network Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Over-the-top (OTT) applications for communication services, such as voice and video calls, do not provide the same quality-of-service (QoS) as integrated native applications due to differences in infrastructure support, with OTT infrastructure lacking prioritization, traffic management, and low latency enhancements available in native network-side infrastructures.
Innovation Solution
A native-based support service for OTT applications that registers with native networks, such as IMS or VoLTE, to associate its identity with the native application's identity, allowing the network to provide QoS enhancements typically reserved for native applications, using Session Initiation Protocol (SIP)-based messaging for mobile originating and terminating procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If OTT applications use Internet-based infrastructure, then service accessibility and device compatibility are improved, but quality-of-service (prioritization, traffic management, low latency) deteriorates
Solution Approach 1:
The patent introduces a native application as an intermediary component that bridges the OTT application and the network infrastructure. The native application registers with the network (IMS/VoLTE) to establish QoS policies, while the OTT application continues to operate over Internet-based infrastructure. This intermediary enables QoS enhancements without requiring the OTT application itself to be modified or to use native network infrastructure directly.
2Adaptability or versatility
If OTT applications use Internet-based infrastructure, then device compatibility is improved, but latency and traffic management capabilities worsen
Solution Approach 1:
The native application performs preliminary registration with the network infrastructure before the OTT application initiates communication sessions. This advance registration establishes QoS policies, prioritization rules, and traffic management parameters in the network, ensuring that when the OTT application communicates, the necessary latency reductions and traffic management are already in place without adding delay to the actual communication process.
3Reliability
If native network infrastructure is used for QoS enhancements, then communication service quality is improved, but network resource requirements increase
Solution Approach 1:
The native application serves multiple functions: it acts as a QoS policy manager, a network registrar, and a traffic descriptor provider. By consolidating these functions into a single native application component, the system avoids deploying separate network elements or additional infrastructure for each function, thereby reducing overall network resource requirements while still providing comprehensive QoS enhancements for the OTT application.

AI summary
A method, a device, and a non-transitory storage medium are described in which a native-based support service for an over-the-top application is provided. A network device provides a registration procedure that enables a linking between an identity of the over-the-top application and an identity of a native application for a communication service, and enables a quality of service to be provisioned afforded to the native application for the over-the-top application. The network device provisions originating and terminating communication sessions of the communication service having the native quality of service in relation to the identity of the over-the-top application.
