Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP standard does not specify how to provide network assistance information to user equipment (UE) to improve quality of experience (QoE) for streaming media sessions.
Innovation Solution
A method and apparatus for providing network assistance information through a network data analytics function (NWDAF) that generates and transmits network assistance information to user equipment (UE) via a control plane, including data transmission rate and packet latency predictions to optimize streaming media sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network assistance information is provided to improve QoE of streaming media sessions, then quality of experience is improved, but the existing standard lacks specification on how to provide this information
Solution Approach 1:
The patent introduces an Application Function (AF) as an intermediary entity that bridges the gap between the NWDAF and UE. The AF receives analytics information from the NWDAF, processes it into network assistance information, and provides it to the UE. This intermediary resolves the contradiction by creating a standardized information flow path when direct specification between NWDAF and UE is lacking.
Solution Approach 2:
The patent segments the network assistance information providing process into distinct functional modules: NWDAF for analytics generation, AF for information processing and management, and UE for receiving and acting on the information. This segmentation allows each component to be independently specified and standardized, resolving the lack of comprehensive standard specification.
2Ease of operation
If network assistance information is provided through standardized protocols, then ease of operation is improved, but the information may not be timely or accurate enough for optimal streaming performance
Solution Approach 1:
The patent implements a feedback mechanism where the AF continuously monitors network conditions, receives analytics from NWDAF, and adjusts the network assistance information provided to the UE in real-time. This feedback loop ensures that the standardized protocol remains flexible and responsive to changing network conditions, maintaining both standardization and accuracy.
Solution Approach 2:
The patent makes the network assistance information dynamic by allowing the AF to adjust the type, frequency, and content of information provided based on current network conditions and UE requirements. This dynamic approach enables the standardized protocol to adapt to varying precision requirements without losing its standardized structure.
