Solution Overview

Problem

Current wireless positioning systems face challenges in selecting the most suitable positioning solution for specific scenarios, leading to increased positioning failures and reduced accuracy due to improper solution application.

Innovation Solution

A method and apparatus for selecting a positioning solution based on channel information allocated to a terminal, which involves receiving channel information and selecting a suitable solution from a set of positioning solutions, such as MS-based AGPS, MS-assisted AGPS, or Cell ID-based solutions, to adapt to different traffic scenarios and improve positioning success rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a positioning solution is improperly applied in a concrete scenario, then the positioning accuracy is reduced, but the positioning failure possibility is highly increased

Engineering Contradiction:
Improvepositioning success rateVSAvoidpositioning accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent implements dynamic positioning solution selection by having the network device adaptively choose different positioning solutions (autonomous mode or assisted mode) based on real-time channel conditions and scenario characteristics. The system transitions between different positioning modes dynamically rather than using a fixed approach, thereby optimizing both reliability and accuracy for each specific scenario.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes key parameters including the positioning mode (autonomous vs. assisted), assistance data configuration, and channel allocation strategies based on scenario requirements. By adjusting these parameters adaptively, the system resolves the contradiction between positioning success rate and accuracy, ensuring optimal performance for each concrete scenario.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple positioning solutions are available for different scenarios, then the adaptability is improved, but the device complexity is increased

Engineering Contradiction:
Improvepositioning solution adaptabilityVSAvoidpositioning system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where the network device autonomously evaluates channel conditions and automatically selects the appropriate positioning solution without requiring complex manual configuration or user intervention. The system serves itself by making intelligent decisions based on predefined criteria and real-time measurements, thereby achieving high adaptability while managing complexity through automation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent creates a universal positioning framework that can handle multiple scenarios (autonomous mode, MS-assisted mode, MS-based mode) through a single integrated system. The network device possesses multi-functionality by supporting various positioning solutions and assistance data types, allowing it to adapt to different scenarios without requiring separate dedicated systems for each mode.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If assistance data is provided to improve positioning accuracy, then the measurement precision is improved, but the loss of information is increased due to more assistance data requirements

Engineering Contradiction:
Improvepositioning measurement accuracyVSAvoidassistance data overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies partial action by providing assistance data selectively rather than always providing complete assistance data sets. The network device evaluates whether assistance data is actually needed based on the scenario and terminal capabilities, providing only the necessary portion. This approach improves positioning accuracy when needed while minimizing information overhead by avoiding unnecessary assistance data transmission.

Inventive Principle:
Principle #16Partial or excessive action
