Privacy Profile Segmentation for Mobile Terminal Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack effective mechanisms for ensuring user privacy and consent processing, particularly in scenarios where multiple network functions are involved, leading to potential unauthorized access and lack of control over positioning services.
Innovation Solution
Implementing privacy profile settings on mobile terminals and network nodes to verify user consent before sharing positioning information, using security tokens and message authentication codes to secure communication and update privacy settings, ensuring that only authorized parties access location data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If positioning information is shared across network functions, then service functionality is improved, but user privacy protection deteriorates
Solution Approach 1:
The patent segments positioning information into multiple privacy levels (first privacy level for network functions, second privacy level for other entities). This segmentation allows different portions of positioning data to be shared with different entities based on their authorization, enabling service functionality while protecting user privacy through controlled disclosure.
Solution Approach 2:
The patent introduces a privacy management function as an intermediary between the user equipment and various network functions. This intermediary receives positioning information, applies privacy rules, and selectively forwards information to authorized entities. The mediator ensures that service functionality is maintained while preventing unauthorized privacy exposure.
2Ease of operation
If privacy profile settings are updated frequently, then user control over positioning is improved, but network security risks increase
Solution Approach 1:
The patent establishes security mechanisms in advance before privacy profile updates occur. Security tokens are pre-configured with cryptographic keys, and authorization rules are predefined. When privacy updates are requested, these pre-established security measures automatically validate the request, enabling user control while maintaining network security through proactive protection.
Solution Approach 2:
The patent implements a feedback mechanism where privacy profile updates trigger security verification processes. The network function receives the update request, validates it against security tokens and authorization rules, and only applies the update if verification succeeds. This feedback loop ensures user control is exercised safely while maintaining network security integrity.

AI summary
A method performed by a mobile terminal for verifying at least one privacy profile setting for positioning of the mobile terminal to a location network node in a communications network is provided. The method includes receiving a request from the location network node for the mobile terminal to provide a position of the mobile terminal. The method further includes checking the at least one privacy profile setting of the mobile terminal for permission to provide position information of the mobile terminal. The method further includes determining whether to send the positioning information of the mobile terminal to the location network node based on the checking the at least one privacy profile setting. Methods performed by a network node are also provided.
