Personal IoT Network Event-Triggered Information Updating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently updating personal IoT network (PIN) information, particularly in response to events such as expiration of valid time, addition or removal of PIN elements, updates to PIN policies or configuration parameters, and changes in capability, which are crucial for maintaining normal communication.
Innovation Solution
A method is provided where a first PIN element with management capability (PEMC) determines a predetermined event and sends PIN update request information to a network function, which then updates the PIN information accordingly, involving network functions like AMF, UDM, and PMF to ensure timely updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If PIN information is updated manually or periodically, then system complexity is reduced, but timeliness of updates deteriorates
Solution Approach 1:
The system performs preliminary configuration by establishing event-triggered update mechanisms in advance. When specific events occur (such as PIN element changes, policy updates, or capability changes), the system automatically initiates update actions without requiring manual intervention or periodic checks, thus achieving timely updates while maintaining simple operation.
Solution Approach 2:
The system implements feedback mechanisms where network functions monitor PIN element status and automatically trigger update procedures when changes are detected. The network function receives notifications about events (addition, removal, or update of PIN elements) and responds by updating PIN information in real-time, ensuring timeliness through automatic feedback loops.
2Reliability
If PIN information is updated frequently to ensure timeliness, then update timeliness improves, but network signaling overhead increases
Solution Approach 1:
Instead of updating all PIN information indiscriminately, the system performs partial updates only for specific elements that have changed. When a particular PIN element undergoes addition, removal, or modification, only the relevant portion of PIN information is updated and notified, avoiding unnecessary full updates and reducing signaling overhead while maintaining information accuracy.
Solution Approach 2:
The PIN information update mechanism is segmented into specific event types (addition of PIN element, removal of PIN element, update of PIN element, policy changes, capability changes). Each segment handles only its specific update scenario, allowing targeted updates rather than blanket updates, thus reducing unnecessary network signaling while ensuring accurate information maintenance.
3Ease of operation
If manual update procedures are used, then ease of operation is improved, but update timeliness deteriorates
Solution Approach 1:
The system implements self-service automation where the network function automatically detects events related to PIN elements and initiates update procedures without human intervention. The system monitors itself for changes in PIN elements, policies, or capabilities and autonomously triggers update actions, combining operational simplicity with timely responses.
Solution Approach 2:
The system is pre-configured with event monitoring capabilities and automatic update triggers. When specific events occur (such as PIN element changes), the pre-established mechanisms automatically activate to update PIN information, eliminating the need for manual update procedures while maintaining operational simplicity through automated event-driven responses.

AI summary
A method for updating personal IoT network (PIN) information is executed by a first PIN element with management capability (PEMC). The method includes: determining that a predetermined event of a first PIN element (PINE) is triggered, and sending PIN update request information to a first network function, wherein the PIN update request information is configured to request to update PIN information.
