IoT Device Identification via Server-Mediated Identifier Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Internet of Things (IoT), users face challenges in identifying devices connected to their terminals through short-range wireless communication, particularly when multiple devices are present, leading to incorrect connections and user confusion.
Innovation Solution
An information processing method and system that associates first and second identifiers with connection status for each device, allowing the terminal to transmit a completion notification to the server, which then identifies and transmits the second identifier to the terminal for display, enabling easier device identification and preventing connection errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal device uses its own identifier to identify connected devices, then the identification process is simple, but the user cannot easily distinguish between multiple devices with similar identifiers
Solution Approach 1:
The patent introduces a server as an intermediary between the terminal device and the cloud service. The server receives completion notifications from the terminal device, manages identifier mappings in a database, and returns appropriate identifiers to the terminal. This intermediary system resolves the conflict between simple identification and distinguishable device identification by centralizing the identifier management function.
Solution Approach 2:
The patent segments the identifier management function across multiple components: the terminal device generates initial identifiers, the server manages and maps identifiers, and the cloud service stores and retrieves identifier information. This segmentation allows each component to perform its specific function optimally while maintaining overall system coherence and user-friendly operation.
2Productivity
If the terminal device automatically connects to devices without verification, then the connection process is fast, but connection errors increase when multiple devices are present
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device sends completion notifications to the server after successful coupling with a device. The server uses this feedback information to update its database with the correct identifier mappings. This feedback loop ensures that the system learns from each connection event and maintains accurate identifier associations, preventing connection errors in the future.
Solution Approach 2:
The patent performs preliminary actions by having the terminal device detect nearby devices and their identifiers before establishing connections. The server pre-manages the mapping between device identifiers and user-friendly names. This preliminary preparation allows the terminal to quickly identify and connect to the correct device without verification errors, maintaining both speed and accuracy.
3Measurement precision
If the system uses complex identifier management to distinguish devices, then device identification accuracy improves, but the system complexity increases
Solution Approach 1:
The server acts as an intermediary that handles the complex identifier management tasks. Instead of the terminal device or cloud service managing identifiers independently, the server centralizes this function, maintaining a database that maps technical identifiers to user-friendly names. This intermediary approach simplifies the overall system architecture while maintaining high identification precision.
Solution Approach 2:
The patent creates a copy of the identifier mapping information in the server's database, separate from the actual device identifiers. This copy allows the system to maintain simple device identifiers while storing the complex mapping relationships in the cloud service, reducing the complexity at each individual level while maintaining overall precision.

AI summary
An information processing method includes coupling, by a terminal device of a plurality of terminal devices, to a device of a plurality of devices through wireless communication; transmitting a completion notification indicating that the coupling to the device is successful to an information processing device; referring, by the information processing device, to management information in which a first identifier, a second identifier, and a connection status of connection with the plurality of terminal devices are associated with each other for each of the plurality of devices to identify the second identifier that is included in the completion notification and associated with the first identifier that is used to identify the device, by using the information processing device, transmitting the identified second identifier to the terminal device; and displaying, by the terminal device, the identified second identifier.
