Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a latency reduction function in mobile communication systems poses a risk of incorrect network optimization when MDT measurement results from user terminals with and without the latency reduction function are mixed, potentially leading to suboptimal network performance.
Innovation Solution
A communication device controller adds identification information to MDT measurement results indicating whether the latency reduction function is applied, allowing for differentiation between measurement results from user terminals with and without the latency reduction function, thereby preventing incorrect network optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If MDT measurement results from user terminals with and without the latency reduction function are collected together, then the quantity of measurement data is increased, but the accuracy of network optimization is degraded due to mixing incompatible measurement results
Solution Approach 1:
The patent segments MDT measurement results by adding identification information that distinguishes measurements taken with the latency reduction function from those taken without it. This segmentation allows the network device to separately analyze and process measurement data based on the functional state of the user terminal, preventing mixing of incompatible measurements while maintaining comprehensive data collection.
Solution Approach 2:
The patent introduces identification information as an intermediary element that bridges the gap between diverse measurement conditions. This identifier acts as a mediator that enables the network device to recognize and differentiate between measurement results obtained under different latency reduction function states, allowing accurate processing without requiring separate collection systems.
2Measurement precision
If identification information is added to MDT measurement results to distinguish latency reduction function application status, then the accuracy of network optimization is improved, but the complexity of data processing is increased
Solution Approach 1:
The patent applies local quality by adding identification information only to specific fields within the MDT measurement result data structure. Rather than fundamentally changing the entire data processing system, the identification tag is locally integrated into existing measurement reports, minimizing system-wide complexity while enabling precise differentiation of measurement conditions.
3Speed
If the latency reduction function is applied to radio communication, then the transmission speed is improved, but the reliability of network optimization is degraded due to inability to distinguish measurement results
Solution Approach 1:
The patent implements preliminary action by pre-configuring user terminals with the capability to include identification information in their MDT measurement reports before actual measurements are taken. This preparatory setup ensures that as measurements are collected during high-speed operation, the identification data is already embedded, allowing immediate and reliable differentiation without requiring post-processing analysis.

AI summary
A communication device according to an embodiment comprises: a controller configured to perform radio communication with another communication device in a mobile communication system to which an MDT function is applied. The controller obtains an MDT measurement result obtained by measuring a parameter in the radio communication. The parameter is a parameter affected by a latency reduction function. The controller adds, to the MDT measurement result, identification information on whether or not the latency reduction function is applied, depending on whether or not the latency reduction function is applied to the radio communication.
