RAN Terminal Data Correlation Using Temporary Identifier Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The radio access network (RAN) side is unable to correlate and analyze data of a single terminal device due to the inability to perceive identifiers, leading to challenges in data analysis and privacy concerns.
Innovation Solution
A method for correlating data of a terminal device involves a first device obtaining correlation information and identifiers, which are then sent to a second access network device for data analysis, using techniques such as generating temporary identifiers to protect privacy and requesting specific data based on time windows and network areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the RAN side obtains terminal device data for analysis, then data analysis capability is improved, but terminal device privacy is compromised due to direct identifier exposure
Solution Approach 1:
The patent introduces an intermediary device (third device) that acts as a mediator between the RAN side and terminal devices. This intermediary generates temporary identifiers and provides correlation information without exposing actual terminal identifiers, thus enabling data analysis while protecting privacy. The intermediary translates between anonymous temporary identifiers used by RAN and real terminal identifiers, solving the contradiction between analysis capability and privacy protection.
Solution Approach 2:
The patent creates a copy of the terminal identifier system through temporary identifiers. Instead of using real terminal identifiers directly, the system generates temporary identifier copies that can be used for data correlation and analysis. These temporary identifiers functionally replace real identifiers in the RAN context, enabling analysis capability while the original identifiers remain protected. The correlation information serves as a mapping copy that links temporary and real identifiers without exposing the latter.
2Object-affected harmful factors
If the RAN side cannot correlate terminal device data, then privacy is protected, but data analysis capability deteriorates
Solution Approach 1:
The patent segments the identifier system into two distinct parts: temporary identifiers used by the RAN side for data correlation and real terminal identifiers kept protected. The correlation information acts as a separate linking mechanism that connects these segments without merging them. This segmentation allows the RAN to perform data analysis using temporary identifiers while the real identifiers remain isolated and protected, resolving the contradiction between privacy protection and analysis capability.
Solution Approach 2:
The correlation information serves as an intermediary layer that enables data correlation without direct exposure of terminal identifiers. The RAN side uses temporary identifiers and correlation information to link data from multiple sources, achieving analysis capability while the actual terminal identifiers never leave the protected domain of the intermediary device. This intermediary mechanism breaks the direct link between analysis operations and privacy-sensitive data.
3Object-affected harmful factors
If temporary identifiers are generated for privacy protection, then privacy leakage is reduced, but system complexity increases due to additional identifier management
Solution Approach 1:
The patent implements self-service mechanisms where the intermediary device automatically generates temporary identifiers and manages correlation information without requiring manual intervention. The system autonomously handles the creation, distribution, and mapping of temporary identifiers to real identifiers. This automation reduces the operational complexity burden, making the additional identifier management overhead manageable through self-service processes rather than manual procedures.
Solution Approach 2:
The temporary identifier system is designed to be universal and multi-functional, serving multiple purposes: data correlation, privacy protection, and network management. The same temporary identifier mechanism is used across different RAN nodes and for various types of terminal device data, consolidating what could be multiple separate systems into a single unified approach. This universality reduces overall system complexity by avoiding the need for separate identifier management systems for different functions.

AI summary
A method for correlating data of a terminal device and an apparatus are provided, to correlate data of a single terminal device by a RAN side, and further analyze the data of the terminal device. The method is: A first device obtains first data of a terminal device on a second device, where the first data includes first correlation information, the first correlation information is used to correlate the first data with second data of the terminal device on a first access network device, the second data includes the first correlation information, and there are one or more terminal devices. The first device determines a first identifier of the terminal device, and sends the first correlation information and the first identifier of the terminal device to a second access network device.
