UE-Triggered Network Slicing for Dynamic QoS Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network slicing technologies do not effectively accommodate dynamic changes in user equipment (UE) preferences and application requirements, leading to suboptimal quality of service (QoS) and quality of experience (QoE) due to pre-provisioned slices that do not consider UE capabilities or dynamic changes in application servers or UE states.
Innovation Solution
User equipment (UE) is empowered to trigger dynamic network slicing by generating reports based on its preferences and conditions, allowing for on-demand selection and reconfiguration of network slices to align with real-time QoS/QoE parameters, using interfaces with the base station and application server to manage URSP policies and slice configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-provisioned network slices are used, then network configuration is simplified and initial setup is faster, but the network cannot adapt to dynamic changes in user preferences and application requirements
Solution Approach 1:
The patent implements dynamic network slicing where the network slice configuration changes in real-time based on user equipment preferences and application requirements. The network slice is no longer static but adapts dynamically to user needs, transforming the network architecture from a pre-provisioned static model to a dynamic on-demand model that responds to changing conditions.
Solution Approach 2:
The user equipment is empowered to autonomously trigger network slice configuration based on its own preferences and detected conditions. The UE generates reports containing its preferences and conditions, and uses these to select or request appropriate network slices without requiring manual network operator intervention, enabling self-service network configuration.
2Reliability
If pre-provisioned network slices are deployed, then initial network setup is faster, but quality of service and quality of experience deteriorate due to inability to consider UE capabilities and dynamic changes
Solution Approach 1:
The user equipment proactively prepares by generating and maintaining a report containing its preferences and conditions before actual network slice selection is needed. This preliminary preparation enables faster and more accurate slice selection when applications are launched or conditions change, eliminating the need for time-consuming analysis at the moment of need.
Solution Approach 2:
The system implements feedback loops where the network receives reports from UE about its preferences and conditions, and this information is used to select or configure appropriate network slices. The feedback mechanism ensures that network slice configuration continuously reflects current UE state and application requirements, maintaining high QoS.
3Adaptability or versatility
If dynamic on-demand network slicing is implemented, then quality of service and adaptability improve, but network signaling and control complexity increases
Solution Approach 1:
The patent uses universal information elements and report structures that can serve multiple functions. The same report containing UE preferences and conditions is used for network slice selection, configuration, and optimization across different scenarios and applications, reducing the need for separate signaling mechanisms for each function.
