Dynamic Positioning Session Configuration via Routing Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in power consumption and resource usage due to unnecessary physical layer positioning sessions, particularly in stationary devices that incur significant signaling overhead and processing power, as they periodically perform redundant measurements.
Innovation Solution
An apparatus and method that monitor routing parameters at the protocol layer above the physical layer to determine stability or change, triggering or deactivating physical layer positioning sessions based on these parameters, reducing the number of positioning reference signals and measurements, and adjusting configurations dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical layer positioning sessions are performed periodically to ensure location accuracy, then positioning reliability is improved, but power consumption and signaling overhead increase
Solution Approach 1:
The positioning session periodicity is made dynamic rather than fixed. The system adjusts the positioning session execution frequency based on real-time routing parameter changes detected at upper protocol layers. When routing parameters remain stable, positioning sessions are deferred or skipped; when changes are detected, positioning sessions are triggered to update location information, thus adapting the positioning behavior to actual movement conditions
Solution Approach 2:
The system establishes a feedback mechanism where upper protocol layer routing parameter information is monitored and fed back to control physical layer positioning session execution. The routing parameter stability detection results from network layer protocols provide feedback that determines whether positioning measurements should be performed, creating a closed-loop control system that optimizes positioning resource usage based on actual positional change indicators
2Reliability
If physical layer positioning sessions are performed periodically to ensure location accuracy, then positioning reliability is improved, but signaling overhead increases
Solution Approach 1:
The system dynamically adjusts positioning session execution based on routing parameter stability. Instead of fixed periodic positioning, the positioning behavior adapts to actual movement conditions indicated by routing parameter changes. When routing parameters are stable, positioning signaling is reduced or eliminated; when changes occur, positioning signaling is triggered, making the signaling overhead dynamic and condition-dependent
Solution Approach 2:
The system changes the execution parameter of positioning sessions from a fixed time-based schedule to an event-driven schedule based on routing parameter changes. By monitoring routing parameter stability and triggering positioning sessions only when changes are detected, the system optimizes signaling overhead by performing positioning measurements only when actually needed, rather than following a rigid periodic schedule
3Measurement precision
If routing parameters are monitored frequently to detect movement, then positioning accuracy is improved, but processing power increases
Solution Approach 1:
The system performs preliminary monitoring of routing parameters at the network layer before triggering physical layer positioning sessions. By detecting routing parameter changes in advance at the protocol layer (which has lower processing overhead), the system can determine whether positioning measurements are actually needed, thus avoiding unnecessary high-power physical layer positioning operations while maintaining positioning accuracy when movement occurs
