5G UE Session Prioritization for Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, there is a need to prioritize positioning sessions over radio communication sessions to ensure accurate and timely location determination of user equipment (UE) while managing resource conflicts and meeting quality of service criteria, particularly in scenarios where positioning signals and radio communications require concurrent use of operational resources.
Innovation Solution
The implementation of a method in user equipment (UE) to identify potential collisions between positioning and radio communication sessions, determine priorities based on scheduled measurement gaps, positioning techniques, and report requirements, allowing for the prioritization of positioning sessions over radio communication sessions when necessary, ensuring that positioning information is obtained and reported with desired criteria without disrupting other radio communication procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning sessions are prioritized over radio communication sessions, then positioning accuracy and timeliness are improved, but radio communication quality may deteriorate
Solution Approach 1:
The patent dynamically changes the parameter of session prioritization by introducing a priority indicator that can be configured to favor either positioning or radio communication sessions. This allows the system to adapt the prioritization parameter based on current network conditions and service requirements, resolving the contradiction by making the prioritization flexible rather than fixed.
Solution Approach 2:
The patent implements dynamic session handling by allowing the priority between positioning and radio communication sessions to be adjusted in real-time. The system can dynamically switch which session type gets priority based on current needs, making the system adaptive rather than static, thus resolving the contradiction between positioning accuracy and communication quality.
2Productivity
If positioning sessions are performed concurrently with radio communication sessions, then resource utilization is improved, but collision and interference increase
Solution Approach 1:
The patent applies preliminary action by identifying potential collisions between positioning and radio communication sessions before they occur. The system proactively schedules sessions to avoid conflicts, rather than reacting to collisions after they happen. This prevents interference while still allowing high resource utilization by planning ahead.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a priority indicator and session management system that mediates between positioning and radio communication sessions. This intermediary resolves conflicts by determining which session should proceed when resources are contested, thus reducing collisions and interference while maintaining high resource utilization.
3Reliability
If multiple sessions are managed with priority indicators, then session collision is reduced, but system complexity increases
Solution Approach 1:
The patent segments the session management function by introducing separate priority indicators for different session types (positioning vs. radio communication). This segmentation allows independent control and prioritization of different session categories, reducing collisions through structured management while keeping the complexity localized to specific management functions rather than the entire system.
