Wireless Pairing via Application Identification Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices require complex operations for pairing and re-pairing, leading to user unfriendliness and potential errors, especially when shared keys are involved and pairing information is deleted from one device's memory.
Innovation Solution
A wireless communication method that includes a notification step for transmitting application identification information and storing device identification information between devices, simplifying the pairing process by eliminating the need for shared key generation and deletion operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pairing methods using shared keys are used, then security authentication is achieved, but the operation complexity increases and user friendliness decreases
Solution Approach 1:
The patent extracts the shared key generation and management process from the pairing procedure. Instead of requiring devices to generate and manage shared keys, the system uses pre-stored device identification information that is automatically transmitted and used for authentication, eliminating the complex shared key management while maintaining security
Solution Approach 2:
The system enables devices to automatically perform authentication using pre-configured device identification information stored in their memories. The devices self-serve by automatically transmitting and verifying their identification information without requiring user intervention for key management, simplifying the pairing operation
2Adaptability or versatility
If pairing information is deleted from one device's memory, then the pairing is canceled, but it creates uncertainty about whether to generate new pairing information or delete information from the other device
Solution Approach 1:
The patent implements a feedback mechanism where devices automatically detect the presence or absence of matching device identification information in their memories. When reconnection is attempted, the system provides feedback by comparing stored identification information with received information, automatically determining whether to establish connection or cancel pairing based on this feedback, eliminating the uncertainty of manual key management
Solution Approach 2:
The device identification information acts as an intermediary that mediates the pairing state between two devices. Instead of directly managing shared keys that require synchronized deletion, the system uses identification information comparison as an intermediary mechanism to automatically determine pairing status and initiate appropriate actions, ensuring information consistency without manual intervention
3Adaptability or versatility
If manual deletion of shared keys is required to cancel pairing, then pairing cancellation is achieved, but the operation time and user effort increase
Solution Approach 1:
The patent applies preliminary action by pre-storing device identification information in each device's memory before pairing is needed. This pre-configured information is automatically transmitted and used for authentication, eliminating the need for time-consuming manual key deletion operations. The system is prepared in advance with the necessary identification data, enabling rapid pairing cancellation and re-establishment
Solution Approach 2:
The system enables automatic self-service for pairing cancellation by detecting the absence of matching device identification information. When a device attempts to connect and its identification information is not found in the other device's memory, the system automatically cancels the pairing without requiring user intervention for manual deletion, significantly reducing the time and effort required for pairing management

AI summary
In a pairing establishment process, a controller (220) of a central (200) notifies a peripheral of the application identification information on the central (200). The controller (220) of the central (200) stores the device identification information on the peripheral received therefrom in a ROM (240). The application identification information is information to identify an application (that is, software) owned by the central (200). The application is to perform various communications with the peripheral.
