5G to Wi-Fi QoS Mapping for Seamless Flow Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is currently no seamless mechanism for mapping Quality of Service (QoS) attributes from 5G networks to Wi-Fi networks, leading to a lack of access network agnosticism in QoS handling.
Innovation Solution
The proposal introduces a mechanism to map 5G QoS parameters to Wi-Fi, enabling seamless QoS flow transitions between 5G and Wi-Fi networks by defining a table that maps 5G QoS identifiers (5QI) to equivalent Wi-Fi QoS characteristics, such as delay budget, packet error rate, and data rates, allowing for consistent QoS management across both networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If QoS flows are moved between 5G and Wi-Fi networks, then network flexibility and user experience are improved, but QoS consistency and management complexity worsen due to lack of mapping mechanism
Solution Approach 1:
The patent introduces a QoS mapping mechanism that acts as an intermediary between 5G QoS parameters (5QI, QoS characteristics) and Wi-Fi QoS parameters (QoS characteristics element). This mapping table translates source network parameters to target network parameters, enabling seamless QoS flow transitions while maintaining consistency across different access networks.
Solution Approach 2:
The patent transforms QoS parameters from one network domain to another by changing their representation. The mapping mechanism converts 5G-specific parameters (5QI values, 3GPP QoS characteristics) into equivalent Wi-Fi parameters (802.11be QoS characteristics), allowing the same QoS flow to be maintained across different network technologies with different parameter systems.
2Ease of manufacture
If separate QoS mechanisms are maintained for 5G and Wi-Fi networks, then each network can be optimized independently, but access network agnosticism deteriorates and seamless transitions become impossible
Solution Approach 1:
The patent creates a universal QoS mapping mechanism that works across both 5G and Wi-Fi networks. The same mapping table and translation process can handle QoS flows from either network, making the system access network agnostic while preserving the ability to optimize each network independently through their respective parameter systems.
3Reliability
If QoS mapping between 5G and Wi-Fi is implemented, then QoS consistency across networks is improved, but the complexity of defining and maintaining mapping tables increases
Solution Approach 1:
The patent establishes QoS mapping tables in advance, before actual QoS flow transitions occur. The mapping relationships between 5G parameters and Wi-Fi parameters are pre-defined and stored, allowing rapid translation during network transitions without real-time computation, thus ensuring consistency while managing complexity through preparation.
4Measurement precision
If detailed QoS parameter mapping is performed, then QoS management precision is improved, but the difficulty of implementation and standardization increases
Solution Approach 1:
The patent segments the QoS mapping process into distinct components: source network parameter extraction, mapping table lookup, target network parameter generation, and QoS characteristics element construction. This segmentation allows each component to be implemented and standardized independently, reducing overall implementation difficulty while maintaining precise QoS management.
