Personal IoT Network PIN Discovery Through PEMC Service Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods do not effectively define how a Personal Internet of Things (IoT) Network (PIN) element can discover and join a PIN that provides a specific service or device type, leading to inefficiencies in service discovery and communication within PIN networks.
Innovation Solution
A method is proposed where a PIN Element with Management Capability (PEMC) receives a request message from a PIN Element (PINE) to join a PIN, determines if the requested service or device type is supported, selects an appropriate PIN, adds the PINE to that PIN, and sends an accept message, utilizing PIN information such as supported services, device types, group identifiers, and user-defined names to facilitate communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing methods are used for PIN discovery, then service discovery and communication can occur, but the process requires multiple message exchanges and is inefficient
Solution Approach 1:
The patent applies preliminary action by having PIN elements publish their service information and device types to the PIN network in advance. When a PINE needs to discover services, the information is already available in the network, eliminating the need for multiple back-and-forth message exchanges. The PEMC can directly query and match services based on pre-published information, significantly reducing discovery time.
Solution Approach 2:
The patent introduces the PEMC (PIN Element with Management Capability) as an intermediary that manages PIN information including service descriptions and device types. The PEMC acts as a central repository and matcher, receiving service queries from PINEs and providing direct matches based on pre-stored PIN information, thereby reducing the number of message exchanges between PINEs and improving discovery efficiency.
2Reliability
If PIN information is not systematically managed, then service matching can occur, but the process becomes complex and unreliable
Solution Approach 1:
The patent applies universality by creating a standardized PIN information structure that serves multiple functions: it describes device types, lists supported services, provides service details, and enables matching. This universal information framework is used by all PINEs and PEMCs in the network, ensuring consistent and reliable service matching while simplifying the discovery process through standardization.
Solution Approach 2:
The patent implements feedback mechanisms where the PEMC provides matching results to PINEs based on their service queries. The system includes feedback loops that allow PINEs to refine their service requests based on available PIN information, and the PEMC to update its database with new service information from joining PINEs, continuously improving matching accuracy and reliability.

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for PIN discovery and communication in a personal IOT network (PIN) by a PIN Element with Management Capability (PEMC). The method includes receiving a request message to join at least one PIN from a PIN Elements (PINE), determining whether the requested service or device type is supported by at least one PIN from a plurality of PINs based on the PIN information, selecting, by the PEMC, the at least one PIN from the plurality of PINs when the requested service or device type is supported by the at least one PIN form the plurality of PINs, adding the PINE to the at least one PIN to communicate the requested service or the device type, sending an accept message to the PINE.
