5G Network Slice QoS Policy Tables for Real-Time Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G network slicing technologies lack the ability to modify network slice quality of service (QoS) after deployment, leading to inefficient resource utilization and poor user experience for applications that could benefit from dynamic QoS adjustments.
Innovation Solution
A unified data repository (UDR) is introduced to enable real-time QoS modifications by receiving requests from user devices, creating QoS policy tables based on priority data, and instructing network functions to apply these policies dynamically, allowing for temporary QoS changes and reversion to original settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slice QoS is fixed after deployment, then network stability is maintained, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic QoS modification for network slices by introducing a QoS modification function that allows real-time adjustment of QoS parameters. The system maintains network stability through controlled modification processes while improving resource utilization by adapting QoS settings to changing network conditions and service requirements.
2Productivity
If network slice QoS is modified in real-time, then resource utilization efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces a QoS modification function as an intermediary component that mediates between network slice management and QoS parameter adjustments. This intermediary layer simplifies the overall system architecture by centralizing modification logic and providing a standardized interface for QoS changes, thereby managing complexity while enabling real-time modifications.
3Ease of operation
If network slice QoS is modified dynamically, then user experience is improved, but control difficulty increases
Solution Approach 1:
The patent implements preliminary configuration of QoS parameters and modification rules before dynamic adjustments are needed. The system pre-defines QoS parameter sets, modification conditions, and approval workflows, which simplifies real-time control by reducing the complexity of on-the-fly decision-making while still enabling responsive user experience improvements.
Data Source
AI summary
A network device may receive, from a user device, a request for data associated with network slices provided to a region or a network, and may provide, to the user device, network slice data, quality of service (QoS) levels, and a policy lookup table based on the request. The network device may receive, from the user device, priority data identifying a network slice for prioritization, a duration of the prioritization, and a policy for the prioritization, and may create, based on the priority data, a QoS policy table that includes a QoS level for the network slice. The network device may cause network functions to utilize the QoS policy table for a user equipment.
