IoT Location Privacy Control Through AMF and UDM Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile networks lack a tracking solution for internet-of-things (IoT) devices, failing to manage who can track or locate them effectively.
Innovation Solution
An information processing method and apparatus that allows a user equipment (UE) to transmit privacy setting requests to an access and mobility management function (AMF) with IoT device identifier information and privacy indication, enabling the AMF, UDM, and network functions to manage and update location service (LCS) privacy information for IoT devices, allowing authorized clients to track or locate them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If location tracking is enabled for IoT devices in mobile networks, then location service functionality is improved, but privacy security deteriorates due to lack of tracking management
Solution Approach 1:
The patent applies preliminary action by establishing privacy setting requests and authorization mechanisms before location tracking occurs. The UE proactively configures privacy settings and authorizes which LCS clients can track the IoT device, preventing unauthorized access before it happens rather than responding to security breaches after they occur.
Solution Approach 2:
The patent introduces an intermediary mechanism through the AMF and UDM that mediate between the UE's privacy settings and the LCS clients' tracking requests. This intermediary layer verifies authorization and manages privacy information, acting as a buffer that protects the UE's privacy while enabling legitimate tracking functionality.
2Reliability
If tracking management for IoT devices is implemented, then privacy security is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional tracking management system where the AMF handles both access mobility management and privacy setting coordination, while the UDM manages both data storage and authorization verification. This consolidation reduces overall system complexity by making existing network functions serve multiple purposes rather than adding dedicated separate systems.
3Reliability
If LCS privacy information is updated and managed, then unauthorized access is reduced, but information processing complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the AMF receives privacy setting requests from the UE, processes them, and updates the UDM with the new privacy information. The UDM then provides feedback by storing and managing these settings, creating a closed-loop system that continuously updates privacy information to prevent unauthorized access while managing complexity through structured feedback processes.

AI summary
An information processing method is performed by a user equipment (UE) and includes: transmitting a privacy setting request to an access and mobility management function (AMF), wherein the privacy setting request includes first identifier information of an internet-of-things (IoT) device and privacy indication information, and the privacy indication information is configured to indicate that a location service (LCS) client is allowed to perform at least one of tracking or locating on the IoT device.
