UE Positioning Update Bypass via Physical Layer Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning systems require mobile devices to repeatedly report location information even when there is little or no change, leading to unnecessary resource consumption and increased latency due to frequent updates.
Innovation Solution
A method where a user equipment (UE) indicates to the wireless network that there is no update in location measurements, allowing the base station to bypass the location server and inform external clients directly, using a physical layer waveform or by omitting report messages when no change is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE repeatedly reports location information to the network, then the positioning accuracy is maintained, but the resource consumption and latency increase
Solution Approach 1:
Instead of always reporting location information, the system inverts the approach by reporting only when location changes occur. The UE monitors its location and sends reports only when movement exceeds a threshold, rather than sending periodic reports regardless of movement status.
Solution Approach 2:
The system performs partial reporting by sending only the necessary location updates rather than complete periodic reports. When the UE is stationary or moving minimally, no report is sent, providing just enough information to maintain positioning accuracy while conserving resources.
2Measurement precision
If the UE repeatedly reports location information to the network, then the positioning accuracy is maintained, but the latency increases
Solution Approach 1:
The system inverts the periodic reporting mechanism by implementing event-triggered reporting. Location information is transmitted only when changes occur, eliminating unnecessary wait times and reducing overall latency in the positioning system.
Solution Approach 2:
The system skips unnecessary reporting cycles when the UE is stationary. By detecting no movement, the system rushes through the reporting process by sending no report at all, thereby reducing latency without affecting positioning accuracy.
3Measurement precision
If the UE sends location information reports frequently, then the positioning accuracy is maintained, but the network resource consumption increases
Solution Approach 1:
The system inverts the reporting strategy by monitoring for changes and reporting only when necessary. This reduces the quantity of location information messages transmitted over the network while maintaining positioning accuracy through selective reporting.
Solution Approach 2:
The system performs partial reporting by transmitting only when location changes occur, using just enough network resources to maintain positioning accuracy without the excess consumption of frequent periodic reporting.

AI summary
During a positioning session in which multiple location reports are provided, a user equipment (UE) that has little or no movement may provide an indication to an entity in the wireless network that there is no update for one or more location measurements. The UE may provide the indication to a serving base station in a Physical layer waveform. The base station may bypass the location server and provide an indication to an external client that the UE position has not changed. The UE may provide the indication to a location server in a location information report or by not sending a location information report by an expiration time. The indication of no update may be provided by a bit that indicates no location measurements are updated or that a particular location measurement is not updated.
