UE Network Slice Assistance for Predictive Mobility Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, lack efficient mechanisms for UE to provide historical and predictive information about network slice usage, which can lead to suboptimal resource allocation and mobility management.
Innovation Solution
A method where user equipment (UE) stores and calculates the usage history and probability of future network slices, and transmits this information to network nodes or entities, allowing for dynamic configuration of network slice structures and assistance in mobility decisions.

Engineering Contradiction Analysis
1Reliability
If the UE provides detailed historical and predictive network slice usage information to the network, then the network can make more informed resource allocation and mobility management decisions, but the UE complexity increases due to the need to store and calculate usage histories and probabilities
Solution Approach 1:
The UE performs preliminary actions by storing historical network slice usage information and calculating probability values for future slice usage before actual mobility events occur. This advance preparation enables the network to make more accurate predictions and resource allocations without requiring complex real-time analysis at the UE during critical moments.
Solution Approach 2:
The mechanism establishes a feedback loop where the UE continuously monitors and reports actual network slice usage, which then refines future probability calculations. This feedback-driven approach allows the UE to learn from past behavior patterns and improve its predictive accuracy over time, balancing the complexity burden with improved performance.
2Measurement precision
If the UE stores and processes extensive historical usage data and calculates future usage probabilities, then mobility management accuracy improves, but the time required for data processing and decision-making increases
Solution Approach 1:
The UE performs preliminary calculations of usage probabilities based on historical data in advance, so that when mobility decisions need to be made, the network already has pre-computed prediction values ready for quick reference. This eliminates the need for time-consuming real-time analysis during critical mobility events.
Solution Approach 2:
The system uses partial action by focusing on calculating and storing only the most relevant usage probability metrics rather than processing every conceivable data point. This selective approach maintains sufficient prediction accuracy while significantly reducing the computational time and data storage requirements.
3Productivity
If the network configures network slice structures dynamically based on UE assistance information, then network efficiency improves, but the signaling overhead and network complexity increase
Solution Approach 1:
The UE provides preliminary assistance information about historical and predicted slice usage patterns before actual network configuration changes are needed. This allows the network to pre-plan and prepare slice configurations in advance, reducing the need for complex real-time signaling and dynamic reconfiguration during mobility events.
Solution Approach 2:
The mechanism enables a form of self-service where the UE autonomously collects, stores, and calculates its own usage patterns and provides this information proactively to the network. This reduces the burden on the network to perform complex analysis of UE behavior, thereby reducing network-side complexity while still achieving efficient adaptive configuration.
