Pico Remote Radio Unit Positioning via Drive Test Data Binding
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Productivity
If multiple construction teams are involved in PRRU installation, then installation capacity is increased, but coordination complexity and costs increase
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.
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.
3Measurement precision
If supervisors perform scanning and binding operations, then data accuracy is improved, but bottleneck occurs reducing productivity
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.
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.
4Adaptability or versatility
If different terminals are used by different engineering teams, then team autonomy is maintained, but costs increase
Solution Approach 1:
The patent designs a universal drive test terminal that can be used by any engineering team for PRRU position collection. This single terminal type provides multi-functional capability to scan PRRU ESNs, communicate with the network management system, and perform binding operations, eliminating the need for each team to have specialized terminals while maintaining operational flexibility.

AI summary
This application discloses a method for positioning a pico remote radio unit and a system for positioning a pico remote radio unit. Drive test information on a terminal side and drive test information on a network management system side are recorded when a drive test is performed, and pico remote radio unit position information and a pico remote radio unit identifier are automatically associated and bound based on the drive test information on the terminal side and the drive test information on the network management system side, to facilitate positioning of a pico remote radio unit, and ensure efficient system operation and maintenance. The method in an embodiment of this application includes: when a drive test terminal performs a drive test, obtaining, by the drive test terminal, drive test information that is on a terminal side and that is of a drive test event, where the drive test event occurs at least once; obtaining, by a network management system server, drive test information that is on a network management system side and that is of the drive test event, where the drive test information on the network management system side includes a pico remote radio unit corresponding to the drive test event; obtaining, by the network management system server, a pico remote radio unit identifier based on the measurement information on the network management system side; and obtaining, by the network management system server based on the measurement information on the network management system side and the drive test information on the terminal side, pico remote radio unit position information bound to the pico remote radio unit identifier.
