Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If flight path information is reported frequently to improve positioning accuracy and mobility performance, then positioning accuracy is improved, but network signaling overhead and latency increase

Engineering Contradiction:

Improvepositioning accuracyVSAvoidreporting latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by reporting only the necessary portion of flight path information. Instead of reporting complete flight path data continuously, the system reports differential changes or selective updates based on whether the aerial vehicle is in autonomous or non-autonomous mode, reducing signaling overhead while maintaining positioning accuracy.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent implements dynamic reporting strategies that adapt to different operational modes. The reporting behavior changes based on whether the aerial vehicle is in autonomous mode (reporting on path deviation from planned trajectory) or non-autonomous mode (reporting periodic position updates), optimizing the balance between positioning accuracy and network signaling efficiency.

Inventive Principle:

Principle #15Dynamics

Solution Approach 1:

The patent implements feedback mechanisms where the network equipment receives differential flight path information and uses it to update the aerial vehicle's position and trajectory. The system monitors path deviations and triggers reports when significant deviations occur, ensuring positioning accuracy is maintained while reducing unnecessary signaling.

Inventive Principle:

Solution Approach 2:

The patent implements dynamic reporting strategies that adapt to different operational modes. The reporting behavior changes based on whether the aerial vehicle is in autonomous mode (reporting on path deviation from planned trajectory) or non-autonomous mode (reporting periodic position updates), optimizing the balance between positioning accuracy and network signaling efficiency.

AI summary

A method for obtaining flight path information comprises: receiving, at a network entity, a capability report indicating a capability of a UE to report a flight path of the UE; and transmitting, from the network entity, a flight path report message that requests the UE to provide: partial-path reporting by reporting first flight path information indicative of a portion of the flight path of the UE that is less than all of the flight path; or triggered reporting by reporting second flight path information in response to occurrence of a trigger event, the second flight path information indicative of at least some of the flight path of the UE; or differential reporting by reporting third flight path information indicative of a difference between a present flight path of the UE and a previous flight path of the UE; or any combination thereof.
