5G Uplink Streaming Policy Selection via Service Descriptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G media streaming architectures do not provide solutions for dynamic policy selection in uplink streaming, despite supporting it for downlink streaming.
Innovation Solution
A method and system for a 5GMS client to receive media entry points and operation point parameters, determine available service descriptions, transmit these to the 5GMS application, select a dynamic policy based on associated parameters, and establish an uplink streaming session with the 5GMS application function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic policies are implemented for downlink streaming, then service quality is improved, but the architecture complexity increases and uplink streaming support is lacking
Solution Approach 1:
The patent extends the downlink dynamic policy framework to support both downlink and uplink streaming through a unified service operation point mechanism. The same architecture that handled downlink policies now serves dual purposes by introducing uplink-specific service operation points, eliminating the need for separate architectural designs and reducing overall system complexity while improving versatility
Solution Approach 2:
The patent introduces dynamic service operation points that can be selected based on real-time conditions for both downlink and uplink streaming. This dynamic selection mechanism allows the system to adapt policies based on current network state, device capabilities, and service requirements, improving service quality without requiring static complex architecture for each streaming direction
2Adaptability or versatility
If service operation points are added for uplink streaming, then functionality is improved, but the number of parameters and configuration complexity increase
Solution Approach 1:
The patent pre-configures service operation point parameters and policy templates in advance through service description files. These pre-defined configurations include uplink-specific parameters such as buffer sizes, encoding settings, and policy rules that are prepared beforehand, reducing the complexity of real-time configuration and parameter management during actual uplink streaming operations
Solution Approach 2:
The patent introduces service descriptions as intermediary documents that mediate between the core network architecture and uplink streaming requirements. These service descriptions encapsulate complex parameter sets and policy configurations, allowing the system to manage uplink functionality without exposing the full complexity of individual parameters to the streaming process
