Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Location-Based Services (LBS) in 5G networks do not allow for the sharing of location information between wireless devices, limiting the ability to provide enhanced services and personalized recommendations based on user habits and practices, and raising privacy concerns.
Innovation Solution
A method is introduced to identify relationships between wireless devices through behavior analysis, allowing for the sharing of relationship information within the communication network, enabling more precise Location Services (LBS) and Location-Based Applications (LBA) by aggregating data from connected devices, while ensuring user approval and privacy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location information is shared between wireless devices, then service precision and personalization are improved, but privacy concerns and security risks increase
Solution Approach 1:
The patent introduces a Location Management Function (LMF) as an intermediary that mediates location information sharing between wireless devices. The LMF receives location information from devices, determines relationships between devices based on this information, and controls the sharing process, thereby enabling precise location-based services while protecting user privacy through centralized management and user consent mechanisms.
2Measurement precision
If behavior information from multiple devices is aggregated, then relationship identification accuracy is improved, but data processing complexity and network load increase
Solution Approach 1:
The patent segments the data processing function by dividing behavior information collection and relationship determination into distinct network functions. The Access and Mobility Management Function (AMF) collects behavior information from wireless devices, while the Location Management Function (LMF) separately performs relationship determination based on this information. This segmentation reduces individual node complexity and distributes the processing load across the network.
3Adaptability or versatility
If location-based services are expanded to include multiple devices, then service versatility is improved, but network function complexity increases
Solution Approach 1:
The patent implements a universal Location Management Function (LMF) that handles multiple location-based service scenarios involving different types of wireless devices (UEs, IoT devices, vehicles). The LMF provides multi-functional support for relationship determination, location information management, and service coordination across diverse device types and service applications, thereby achieving service versatility without proportionally increasing network function complexity.
