Home Network Device Information Sharing via Copying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In home network systems, the registration process for user devices is cumbersome and time-consuming, requiring each user device to individually register home devices, which becomes impractical as the number of devices increases.
Innovation Solution
A method and apparatus that allow user devices to share home device-related information, including unique identifiers and access tokens, with neighboring devices through a connectivity server and service server, enabling efficient registration and access to home devices without requiring each device to perform individual registration processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each user device individually registers home devices, then device control functionality is ensured, but registration time and operational complexity increase significantly
Solution Approach 1:
The patent implements device information copying where a first user device that has registered home devices transmits the registered device information (including device identifiers, control parameters, and access tokens) to a second user device. This copying mechanism allows the second device to obtain control functionality without performing individual registration, thereby significantly reducing registration time while maintaining reliable device control.
2Reliability
If each user device individually registers home devices, then secure access control is maintained, but the number of required operations increases
Solution Approach 1:
The system copies authenticated device information including access tokens and control parameters from a first user device to a second user device. This ensures that the second device receives pre-authenticated credentials, maintaining security while eliminating the need for the second device to perform complex individual registration operations.
Solution Approach 2:
The server acts as an intermediary by receiving device information from the first user device, validating it, and then transmitting the validated information to the second user device. This intermediary mechanism ensures secure information transfer while simplifying the operation for end users who only need to initiate the sharing process without managing complex authentication protocols.
3Adaptability or versatility
If multiple user devices are added to the home network, then system versatility improves, but registration process complexity increases
Solution Approach 1:
The patent merges the registration operations of multiple user devices by allowing device information to be shared and copied across devices. Instead of each device performing separate registration operations, the system combines the registration effort into a single operation where one device registers and then shares the information with others, thereby supporting multiple devices while reducing overall process complexity.

AI summary
An apparatus and method by which a user device in a home network system transmits home-device-related information is provided. The method includes acquiring, from at least one home device, a unique user identifier (UUID) for a related home device, a peer ID (peer ID) which is managed by a connectivity server for managing a connection between the user device and the related home device and that identifies the related home device, a peer group ID for identifying a group of home devices that have registered with a service server for managing device information on the related home device, and a device token containing key information for authenticating the connection to the related home device, selecting a specific user device which will share the UUID, peerID, peer group ID and device token from among neighboring devices, and transferring the UUID, peerID, peer group ID, and device token to the specific user device on the basis of a predetermined sharing method.
