Network Element User Consent Check for MDT Data Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimization of drive tests (MDT) technologies force user equipment to report personal information without consent, increasing burden on terminals and potentially discrediting users, as they actively select and request measurement data without considering user consent.
Innovation Solution
Implementing a method where network elements check and respect user consent before activating MDT tasks, allowing users to agree or disagree to report data, including identifiers, position information, and service experience, thereby controlling the execution of MDT tasks based on user consent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network actively selects a UE for measurement and forcibly requests the UE to report measured data, terminal identifier, and accurate position, then the network detection efficiency is improved, but user privacy is compromised and user consent is violated
Solution Approach 1:
The patent applies preliminary action by obtaining user consent before executing MDT measurement and reporting operations. The network element first acquires consent information indicating whether the user agrees to report measured data, terminal identifier, and position information, then proceeds with the measurement task only after consent is confirmed. This preliminary consent acquisition resolves the contradiction by ensuring productivity improvements do not come at the cost of privacy violations.
2Reliability
If the network forces the UE to execute MDT operations without user permission, then the measurement data collection is ensured, but terminal user experience deteriorates and user discontent increases
Solution Approach 1:
The patent applies dynamics by making the MDT execution process adaptive to user consent status. The network element dynamically adjusts its behavior based on the obtained consent information: if consent is granted, full measurement and reporting operations proceed; if consent is denied, the network respects the user's decision and does not force execution. This dynamic adaptation resolves the contradiction between ensuring data collection reliability and maintaining ease of operation/user experience.
3Measurement precision
If the UE reports terminal identifier and accurate position information, then the measurement precision is improved, but user privacy protection is weakened
Solution Approach 1:
The patent applies local quality by differentiating the reporting behavior based on the type of information and user consent status. When consent is obtained, the UE reports precise position information and terminal identifier to enable accurate measurement analysis. When consent is not obtained, the UE does not report these sensitive personal information elements. This local differentiation of reporting quality based on consent status resolves the contradiction between measurement precision and privacy protection.

AI summary
A method for minimization of drive tests, a method for collecting terminal information, a terminal, and a network element, belong to the field of communication technologies. The method includes: in a process of activating a minimization of drive tests MDT task, checking, by a network element, a consent type of a user corresponding to a selected terminal; sending an MDT task activation command to the selected terminal according to a check result of the consent type; after receiving measured data reported by the selected terminal, performing an operation according to a check result of the consent type. In embodiments of the present invention, check on user consent is implemented in a network detection process, thereby avoiding a case that a user equipment is forced to report personal information without permission of the user and improving the user experience.
