Personal IoT Network PEGC Replacement After Gateway Faults
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replacing a Personal IoT Network (PIN) Element with Gateway Capability (PEGC) are inefficient, particularly in scenarios where the current PEGC experiences hardware failure, power drain, or crash, as they do not account for necessary information transfer and identification of a suitable replacement PEGC.
Innovation Solution
A method and system for detecting the need for PEGC switchover, determining a capable new PEGC based on PIN profile and dynamic information, transmitting a request, receiving an acceptance signal, and notifying PIN Elements and the PIN Management Server (PIN MS) about the role transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the current PEGC experiences hardware failure, power drain, or crash, then service continuity is disrupted, but existing replacement methods do not account for necessary information transfer and identification of a suitable replacement
Solution Approach 1:
The system pre-identifies and stores candidate PEGC elements with gateway capabilities in the PIN profile before failure occurs. When the current PEGC fails, the predetermined selection criteria and candidate list enable immediate replacement without complex real-time evaluation, ensuring service continuity while simplifying the replacement process.
Solution Approach 2:
The PIN Management Server acts as an intermediary that coordinates the PEGC replacement process. It manages the selection criteria, identifies suitable replacement candidates from the PIN profile, and facilitates the switchover, thereby reducing the complexity burden on individual devices while maintaining reliable service continuity.
2Productivity
If a new PEGC is selected without proper evaluation criteria, then replacement speed is improved, but service quality may deteriorate due to unsuitable replacement
Solution Approach 1:
Selection criteria for evaluating PEGC candidates are predetermined and stored in the system before replacement is needed. These criteria include gateway capability requirements and other service quality metrics. When replacement occurs, the pre-established criteria enable rapid evaluation that maintains service quality without sacrificing replacement speed.
3Reliability
If comprehensive information transfer is implemented during PEGC replacement, then service continuity is maintained, but system complexity and overhead increase
Solution Approach 1:
The system extracts and stores essential PEGC-related information (such as gateway capabilities, service configurations, and routing information) in the PIN profile before replacement occurs. During switchover, only this pre-extracted critical information needs to be transferred to the new PEGC, maintaining service continuity while minimizing the complexity and overhead of information transfer.

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method and system for replacing a PIN Element with Gateway Capability (PEGC) in a Personal IoT Network (PIN) by a communication device. The method includes detecting whether there is a requirement for the PEGC switchover or replacement from a current PEGC to a new PEGC in case of an occurrence of one or more fault events. The method further includes determining the new PEGC that is capable of performing role of the PEGC for serving as a gateway node. The method includes transmitting a request signal to the determined new PEGC and thereby receiving a response signal. In case that the receiving response signal indicates an acceptance, the method includes sending a notification message to each of the PIN Elements and a PIN Management Server (PIN MS) indicating that role of the current PEGC is being assigned to the new PEGC.
