AIoT Identifier Type Paging for Low-Energy Inventory Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
AIoT devices, with limited energy storage capacity, inefficiently perform multiple comparisons of different identifier types during inventory procedures due to lack of knowledge about the type of identifier, leading to wasteful energy usage.
Innovation Solution
A network function determines the type of identifier for AIoT devices and communicates this type to a reader device, which includes it in a paging message, allowing the AIoT device to perform a single efficient comparison with stored identifier values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AIoT devices perform multiple comparisons of different identifier types during inventory procedures, then the device can determine its identity, but energy consumption increases significantly
Solution Approach 1:
The network function performs preliminary action by determining and communicating the identifier type to the reader device before the AIoT device needs to perform comparisons. This allows the AIoT device to know in advance which identifier type to use, eliminating the need for multiple comparisons and reducing energy consumption while maintaining reliable identity determination.
2Reliability
If AIoT devices perform multiple comparisons of different identifier types, then identity can be determined, but time consumption increases
Solution Approach 1:
The network function communicates the identifier type to the reader device in advance, allowing the AIoT device to perform a single targeted comparison instead of multiple sequential comparisons. This preliminary communication of identifier type information significantly reduces the time required for identity determination while maintaining accuracy.
3Use of energy by moving object
If the network function communicates identifier type to the reader device, then energy efficiency improves, but device complexity increases
Solution Approach 1:
The reader device acts as an intermediary that receives the identifier type information from the network function and forwards it to the AIoT device. This intermediary approach distributes the complexity: the network function handles identifier type determination, the reader device handles communication, and the AIoT device only needs to perform a single comparison, thereby improving energy efficiency while managing system complexity through clear functional division.

AI summary
Various aspects of the present disclosure relate to communicating types of identifiers to ambient Internet of Things (AIOT) devices, such as during an inventory procedure or other AIOT operations. For example, an AIoT function (AIOTF) may determine the type of identifier to be used during the inventory procedure and communicate the type of identifier to an AIOT reader device. The AIoT reader device may include an indication of the type of identifier in a paging message to the AIOT device (e.g., along with device identification information, such as a value of an identifier for the AIoT device).
