Solution Overview

Problem

Current LTE Positioning Protocol (LPP) techniques require re-initiation of the positioning session for selecting Quality of Service (QoS) parameters, leading to latency issues.

Innovation Solution

The solution involves dynamically updating QoS parameters during an ongoing New Radio (NR) positioning session without re-initiating the session, allowing for continuous and efficient QoS management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the positioning session is re-initiated to select QoS parameters, then the QoS parameters can be properly selected, but latency increases

Engineering Contradiction:
ImproveQoS parameter selection accuracyVSAvoidsession re-initiation latency
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies dynamics by enabling QoS parameter selection during the ongoing positioning session rather than requiring re-initiation. The network entity can dynamically update QoS parameters (such as horizontal accuracy, vertical accuracy, response time) while the positioning session is active, allowing the system to adapt to changing requirements without restarting the entire positioning procedure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing modification of QoS parameters during the positioning session. The network entity receives updated QoS parameter values and applies them to the ongoing session, enabling real-time adjustment of positioning requirements (e.g., changing accuracy levels or response time constraints) without disrupting the active positioning operation.

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If the positioning session continues without re-initiation, then latency is reduced, but QoS parameter updates cannot be applied

Engineering Contradiction:
Improvesession continuity timeVSAvoidQoS parameter update capability
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The patent enables dynamic QoS parameter updates during the positioning session, allowing the system to adapt to changing requirements while maintaining session continuity. The network entity can receive and apply new QoS parameter values without terminating the existing positioning session, thus combining session continuity with adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback mechanisms where the network entity receives QoS parameter updates from the positioning server and applies them to the ongoing session. This feedback loop allows continuous optimization of positioning parameters based on real-time requirements while maintaining an active positioning session.

Inventive Principle:
Principle #23Feedback

AI summary

A user equipment (e.g., a mobile device) may receive a location request message from a server (e.g., a Location Management Function), wherein the location request message identifies a plurality of Quality of Service parameters for the LTE Positioning Protocol (LPP) positioning session. In at least one embodiment, the user equipment may receive a selection of one or more Quality of Service parameters for the LPP positioning session. In at least one embodiment, the user equipment may configure the user equipment according to the one or more selected Quality of Service parameters. In at least one embodiment, the user equipment may generate a location response message according to the selected QoS parameters. The user equipment may send the location response message to the server. A UE can select the QoS parameters during communication with a server and/or with a second UE via sidelink communications.
