Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drive test measurement technologies in radio communications systems are inefficient, leading to high costs and long problem discovery times, as they often report unnecessary measurement data, increasing air interface overhead and delaying network issue resolution.
Innovation Solution
A method where user equipment determines whether to acquire and report Minimization of Drive Tests (MDT) measurement values based on specific triggering parameters such as SINR, data rate, packet loss rate, or service interruption time, reducing unnecessary data transmission and optimizing network problem response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If user equipment reports all MDT measurement values according to network configuration, then measurement data coverage is improved, but air interface overhead increases and network processing burden is aggravated
Solution Approach 1:
The patent changes the parameter of measurement reporting by introducing triggering conditions (SINR thresholds, data rate thresholds, packet loss rate thresholds, service interruption time thresholds) that determine whether MDT measurements are reported. This transforms the reporting behavior from continuous to event-driven, reducing unnecessary reports while maintaining coverage for significant events.
Solution Approach 2:
The patent makes the measurement reporting dynamic by allowing the user equipment to adaptively decide whether to report based on real-time network conditions and configured thresholds. The reporting behavior changes dynamically according to the current measurement values and their comparison with thresholds, rather than following a static reporting schedule.
2Loss of information
If user equipment reports all MDT measurement values, then measurement data completeness is improved, but network response time to problems is delayed
Solution Approach 1:
The patent extracts and reports only the most relevant measurement data by comparing current measurements against configured thresholds. Only measurements that exceed thresholds or indicate abnormal conditions are reported to the network, filtering out normal variations and focusing on significant events that require network attention.
Solution Approach 2:
The patent changes the reporting parameter from comprehensive to selective by introducing threshold-based triggering. This ensures that the network receives timely notifications about abnormal conditions while filtering out routine measurements that do not indicate problems.
3Speed
If MDT measurement reporting is performed continuously, then measurement frequency is improved, but processing burden on network side is aggravated
Solution Approach 1:
The patent implements periodic measurement taking but transforms the reporting into an event-driven action. Measurements are taken periodically according to network configuration, but reports are generated only when measurements trigger specific conditions, converting continuous periodic reporting into selective event-based reporting.
Solution Approach 2:
The patent extracts only the necessary measurement reports from the periodic measurements by applying threshold filters. This reduces the volume of data requiring network processing while maintaining the ability to detect problems at appropriate frequencies.

AI summary
Embodiments of the present application provide a minimization of drive tests measurement method and apparatus. The method includes: determining, by a user equipment, according to an MDT triggering parameter, whether to acquire an MDT measurement value, where the MDT triggering parameter includes at least one of the following: an SINR, a data rate, a packet loss rate of a voice service, a data packet latency, or service interruption time; acquiring, by the user equipment, the MDT measurement value when it is determined to acquire the MDT measurement; and sending, by the user equipment, the MDT measurement value to a network side. The minimization of drive tests measurement methods and devices in the embodiments of the present application are capable of avoiding that a user equipment reports a large amount of useless information, and reducing burdens on an air interface and a network side.
