Solution Overview

Problem

The existing methods for positioning pico remote radio units (PRRUs) during installation and maintenance are inefficient, as they require manual scanning and binding by construction teams, leading to errors and increased costs, and do not allow for accurate identification of PRRU positions, especially when multiple teams are involved and PRRUs are installed inside ceilings.

Innovation Solution

A method and system that utilize drive test information recorded on both a terminal and a network management system to automatically associate and bind pico remote radio unit position information with identifiers, eliminating the need for on-site scanning and enabling efficient maintenance by using a drive test terminal to collect and process data, including measurement event identifiers and position information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual scanning and binding of PRRU ESN and position is performed by construction teams during installation, then position information can be collected, but errors are easily introduced and accuracy cannot be verified

Engineering Contradiction:
Improveposition information accuracyVSAvoiddata collection reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent implements automated feedback mechanisms where the drive test terminal automatically scans PRRU ESNs, retrieves position information from the network management system, and verifies binding accuracy. This closed-loop feedback process eliminates manual errors and provides automatic verification of position data accuracy.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical scanning operations with automated electronic drive test terminals that automatically scan PRRU ESNs and retrieve position information through network communication. This substitution eliminates human error in data collection and binding operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If multiple construction teams are involved in PRRU installation, then installation capacity is increased, but coordination complexity and costs increase

Engineering Contradiction:
Improveinstallation capacityVSAvoidcoordination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent creates a universal drive test terminal system that can be used by any construction team regardless of which team is performing the installation. The terminal automatically coordinates with the network management system to scan, retrieve, and bind position information, providing a multi-functional solution that works across multiple teams without requiring team-specific procedures.

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

Solution Approach 2:

The drive test terminal performs self-service operations by automatically scanning PRRU ESNs, querying the network management system for position information, and completing the binding process without requiring coordination or intervention from multiple construction teams. This self-service capability eliminates coordination complexity while maintaining high installation capacity.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If supervisors perform scanning and binding operations, then data accuracy is improved, but bottleneck occurs reducing productivity

Engineering Contradiction:
Improveposition binding accuracyVSAvoidscanning and binding efficiency
Core Design Contradiction:

Solution Approach 1:

The drive test terminal performs self-service operations by automatically scanning PRRU ESNs, retrieving position information from the network management system, and completing the binding process without requiring supervisor intervention. This automation maintains data accuracy while eliminating the productivity bottleneck caused by supervisor involvement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual supervisor operations with automated drive test terminals that perform scanning, data retrieval, and binding operations electronically. This substitution maintains the accuracy previously achieved by supervisors while dramatically improving productivity by eliminating the human bottleneck.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If different terminals are used by different engineering teams, then team autonomy is maintained, but costs increase
