Solution Overview

Problem

The existing positioning measurement process in cellular mobile communication networks is delayed due to multiple interactions between the user equipment (UE) and the positioning server, leading to inefficiencies in determining the UE's position.

Innovation Solution

The UE actively sends positioning capability information to the positioning server upon a positioning requirement, allowing the server to determine the necessary positioning assistance and request without needing additional interactions, thereby reducing delay and improving efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the UE and positioning server follow the existing interaction process, then the positioning measurement can be completed with proper capability exchange, but the process experiences delayed timing due to multiple interaction rounds

Engineering Contradiction:
Improvepositioning measurement delayVSAvoidinteraction process complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The UE performs capability self-assessment and proactively reports positioning capability information to the positioning server before the actual positioning measurement is initiated. This preliminary action eliminates the need for multiple interaction rounds during the positioning process, as the server already has the necessary capability information to determine appropriate assistance data and measurement requirements.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If multiple interactions are conducted between UE and positioning server, then accurate positioning capability information can be exchanged, but signaling overhead increases

Engineering Contradiction:
Improvepositioning capability information completenessVSAvoidsignaling overhead
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The UE proactively reports its positioning capability information in advance, ensuring the positioning server receives complete and accurate capability data before the positioning measurement begins. This single preliminary reporting action replaces multiple back-and-forth signaling exchanges, thereby reducing overall signaling overhead while maintaining information completeness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The UE autonomously assesses its own positioning capabilities and generates the capability information report without requiring the positioning server to query or request specific capability details. This self-service approach minimizes interactive signaling, as the UE independently prepares and transmits the necessary information in one action.

Inventive Principle:
Principle #25Self-service
