Cell Reselection Priority Conflict Resolution in User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining cell reselection priority in wireless communication systems face conflicts between relative frequency priorities, particularly when multiple frequencies support different slices with varying priorities, leading to inconsistencies and confusion in cell reselection.
Innovation Solution
A method for determining cell reselection priority involves a user equipment (UE) that determines relative frequency priorities based on multiple frequency priority strategies. When conflicts arise, the UE selects a corresponding frequency priority strategy to resolve the conflict and determine the relative priority between conflicting frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple frequency priority strategies are applied to determine cell reselection priority, then the system can support more complex frequency prioritization scenarios, but conflicts between different frequency priority strategies arise leading to inconsistent priority determination
Solution Approach 1:
The patent applies parameter changes by dynamically selecting different frequency priority strategies based on configuration parameters. The UE determines which strategy to apply (first frequency priority strategy or second frequency priority strategy) based on network configurations, allowing flexible adaptation to different network scenarios while maintaining consistent priority determination through clear selection criteria.
Solution Approach 2:
The patent introduces an intermediary resolution mechanism that acts as a mediator between conflicting frequency priority strategies. When conflicts arise, the UE follows a predetermined resolution rule that selects one strategy over another, effectively mediating the conflict to achieve consistent priority determination without requiring manual intervention.
2Reliability
If the UE continuously performs cell reselection to reside in cells with higher priority or better signal quality, then service quality improves, but the complexity of determining priority increases when frequency conflicts occur
Solution Approach 1:
The patent segments the frequency priority determination process into distinct, manageable parts. It divides the complex priority determination into separate strategies (first frequency priority strategy for certain frequencies, second frequency priority strategy for other frequencies) and clear resolution rules, making the overall complexity manageable while maintaining high service quality through continuous cell reselection.
3Ease of operation
If frequency priorities are set to control UE residence, then network can manage UE distribution, but conflicts between relative frequency priorities from different strategies create inconsistencies
Solution Approach 1:
The patent implements a feedback mechanism in the form of predetermined resolution rules that provide clear guidance on how to resolve conflicts. When the UE encounters conflicting frequency priorities, the resolution rule acts as feedback information that directs the UE to select the appropriate strategy, ensuring no information is lost and maintaining effective UE residence control.

AI summary
A method for determining a cell reselection priority is performed by a user equipment, and includes: determining at least two relative frequency priorities between at least two frequencies based on at least two frequency priority strategies; and when there is a conflict between the at least two relative frequency priorities, determining at least one frequency priority strategy, and determining the relative frequency priority between the conflicting frequencies based on the determined frequency priority strategy.
