Broadcast MDT Measurement Triggers for 5G Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The base station side in 5G NR networks cannot obtain user equipment (UE) measurement information for rapid radio resource management (RRM) and beam management due to the lack of direct MDT function activation by operation administration and maintenance (OAM).
Innovation Solution
A method and device for triggering MDT measurements using broadcast signaling from the base station, including the addition of UE identities and configuration parameters to initiate MDT measurements and reporting requests, enabling UE to perform and report MDT measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MDT function is activated by OAM in 5G NR, then MDT measurement can be performed, but base station cannot obtain UE measurement information for rapid RRM and beam management
Solution Approach 1:
The patent introduces broadcast signaling as an intermediary mechanism between OAM and base station. OAM activates MDT function through OAM signaling, the base station receives this activation and further triggers UE measurements through broadcast signaling, which then relays measurement information back to the base station. This intermediary broadcast signaling mechanism enables the base station to obtain measurement information without direct OAM control.
2Measurement precision
If traditional drive test method is used, then network performance can be measured, but it requires a lot of manpower, material resources and financial resources
Solution Approach 1:
The patent implements a virtual drive test system where UE devices act as mobile measurement nodes. Instead of deploying physical drive test equipment with operators, the system uses standard UE devices to collect measurement information through broadcast-triggered MDT measurements. The measurement data collected by multiple UEs creates a virtual measurement network that replicates traditional drive test functionality without the associated resource requirements.
3Reliability
If OAM activates MDT function, then MDT measurement can be initiated, but the activation process is complex and time-consuming
Solution Approach 1:
The patent implements preliminary configuration of MDT measurement parameters and broadcast signaling templates in advance. When OAM activates the MDT function, the base station can immediately use pre-configured parameters to trigger measurements without requiring time-consuming real-time configuration. The broadcast signaling structure and measurement parameters are prepared beforehand, enabling rapid activation and measurement initiation.

AI summary
The present disclosure relates to a measurement triggering method and device, measurement method and device, base station, user equipment, and computer-readable storage medium. The measurement triggering method includes: determining that there is a need for a user equipment (UE) to start a minimization of drive test (MDT) measurement; and sending an MDT measurement triggering request through broadcast signaling to trigger a corresponding UE to perform the MDT measurement. In the embodiment of the present disclosure, if it is determined that the UE needs to start the MDT measurement, the MDT measurement triggering request is sent through the broadcast signaling to trigger the corresponding UE to perform the MDT measurement, so that the base station side may obtain UE measurement information for RRM, mobility, and beam management.
