MDT Area Scope Configuration for Public and Non-Public Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MDT measurement collection systems in wireless communication networks fail to support the collection of data from non-public networks (NPNs) and do not allow operators to optimize coverage by comparing neighbor network signals, leading to inefficiencies in network performance optimization.
Innovation Solution
Enhanced logged MDT configuration that includes NPN identity indications in the area scope, allowing UEs to collect and manage MDT measurements across different network types, including public and non-public networks, and manage measurement reporting when switching between networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MDT measurements are collected from non-public networks, then network coverage optimization is improved, but device complexity increases due to need to distinguish between public and non-public networks
Solution Approach 1:
The patent segments the area scope parameter into different types (first area scope for public networks, second area scope for non-public networks). This segmentation allows the UE to distinguish between different network types and collect MDT measurements appropriately for each, improving network coverage optimization without creating excessive complexity by organizing the differentiation into structured categories.
Solution Approach 2:
The patent makes the area scope parameter multi-functional by allowing it to serve both public networks and non-public networks through a single configuration mechanism. The UE can collect MDT measurements from both network types using the same logged MDT configuration, eliminating the need for separate configuration mechanisms and thus improving coverage optimization without proportionally increasing device complexity.
2Reliability
If MDT measurements are collected from both public and non-public networks, then network performance analysis is improved, but loss of information increases due to potential confusion between network types
Solution Approach 1:
The patent segments the measurement collection process by introducing different area scope indicators (first area scope for public networks, second area scope for non-public networks). This segmentation ensures that MDT measurements from different network types are clearly distinguished and not confused, improving network performance analysis while preventing information loss through proper categorization and labeling of measurements from each network type.
3Measurement precision
If granular control of MDT measurements is implemented, then measurement precision is improved, but device complexity increases due to additional configuration requirements
Solution Approach 1:
The patent achieves granular control of MDT measurements through the multi-functional area scope parameter that can be configured for different network types (public and non-public). This universal parameter provides fine-grained measurement control without requiring separate complex configuration mechanisms for each network type, thus improving measurement precision while minimizing the increase in device complexity.
