HeNB Autonomous Positioning via Device Measurements

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In wireless communication systems, the deployment of home evolved Node Bs (HeNBs) without planning can hinder positioning determination for devices, as the positioning server may not be aware of their locations, inhibiting accurate positioning measurements.

Innovation Solution

HeNBs can determine their location based on positioning measurements from connected devices and provide this information to the positioning server, allowing devices to use this data for positioning. Additionally, devices can request assistance information from the positioning server for neighboring cells, enabling positioning determination even when the HeNB is not registered.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If HeNBs are deployed without planning in substantially any location, then network coverage and accessibility are improved, but positioning determination accuracy deteriorates because the positioning server is not aware of their locations

Engineering Contradiction:

Improvedeployment flexibilityVSAvoidpositioning accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The HeNB autonomously determines its own location by receiving positioning measurements from user equipment and calculating its position based on these measurements, eliminating the need for manual registration with the positioning server while maintaining positioning accuracy

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Instead of the positioning server providing location information to the HeNB (traditional approach), the HeNB independently acquires its location information by receiving measurements from user equipment and computing its position, inverting the traditional information flow direction

Inventive Principle:

Principle #13The other way round (Inversion)

2Device complexity

If the positioning server is not aware of HeNB locations, then system complexity is reduced, but positioning determination is inhibited

Engineering Contradiction:

Improvepositioning server complexityVSAvoidpositioning determination reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The positioning determination function is extracted from the positioning server and transferred to the HeNB, allowing the positioning server to remain unaware of HeNB locations while still enabling reliable positioning through the HeNB's autonomous location determination capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The HeNB performs preliminary location determination by receiving measurements from user equipment and computing its position in advance, so that when positioning is needed, the location information is already available without requiring server awareness

Inventive Principle:

Principle #10Preliminary action
