Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional network optimization methods require significant manpower, material resources, and expertise, and existing MDT technologies are inadequate for indoor Bluetooth (BT) and Wireless Local Area Network (WLAN) devices, lacking dedicated mechanisms for performing Minimization of Drive Tests (MDT).
Innovation Solution
A base station configures terminals with measurement events and trigger conditions for BT and WLAN devices, transmitting configuration information via designated signaling to enable targeted MDTs, allowing terminals to report results only when specific conditions are met, thereby optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional network optimization methods are used based on drive test data, then network performance can be evaluated and problems identified, but significant manpower, material resources, and capital investment are required along with very high experience requirements for personnel
Solution Approach 1:
The terminal device autonomously performs measurement and reporting functions that previously required external drive test instruments and expert personnel. The terminal self-configures measurement parameters, self-performs measurements on WLAN/BT devices, and self-reports results to the network, eliminating the need for manual drive test operations and reducing dependency on highly experienced optimization personnel.
Solution Approach 2:
The patent replaces the mechanical drive test system (physical instruments, manual operations, human-driven vehicles) with an electronic/software-based MDT system. The measurement functionality is transferred from external physical instruments to software running on terminal devices, substituting mechanical measurement approaches with electronic measurement and data collection methods.
2Adaptability or versatility
If existing MDT technologies are used, then general network measurements can be performed, but inadequate support is provided for indoor Bluetooth and WLAN devices lacking dedicated measurement mechanisms
Solution Approach 1:
The patent applies different measurement configurations and parameters specifically tailored for indoor WLAN and Bluetooth devices versus general cellular measurements. Dedicated measurement identity indicators and device-specific measurement parameters are configured for WLAN/BT devices, allowing localized optimization of measurement quality for indoor environments while maintaining general MDT functionality for other scenarios.
Solution Approach 2:
The patent introduces new measurement parameters and configuration options specifically for WLAN and Bluetooth measurements, including device identity indicators, measurement quantity parameters (such as signal strength, signal-to-noise ratio), and reporting thresholds. These parameter changes enable precise measurement of indoor devices that differ fundamentally from cellular radio measurements.
3Loss of information
If all measurement results are reported continuously, then complete network data is collected, but resource overhead increases significantly
Solution Approach 1:
The patent implements selective reporting where only measurement results that satisfy specific trigger conditions are reported to the network. Instead of continuous reporting of all measurements, the system performs partial reporting based on event-triggered conditions (such as signal quality thresholds, measurement identity matches), reducing uplink data transmission and network processing requirements while maintaining essential measurement information.
Solution Approach 2:
The patent establishes a feedback mechanism where the network configures measurement parameters and trigger conditions, the terminal performs measurements, and measurement results are reported back when conditions are met. This closed-loop feedback system allows the network to receive only the most relevant measurement data for optimization decisions, avoiding unnecessary data transmission and processing of redundant information.

AI summary
The present disclosure provides a method and apparatus for configuring measurement. The method applicable to a base station includes: configuring a terminal with a measurement event for performing an MDT on a designated network device and a trigger condition for the measurement event; generating first configuration information, where the first configuration information represents the trigger condition for the measurement event; adding the first configuration information to designated signaling; and transmitting the designated signaling to the terminal, such that the terminal performs the MDT on the designated network device, and in response to that a measurement result of the MDT satisfies the trigger condition for the measurement event, the measurement result of the MDT is reported to the base station.
