Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-gateway systems lack a method to determine the optimal gateway for device registration, leading to inefficient device management in smart home networks.
Innovation Solution
A method and apparatus where a master gateway selects performance parameters and collects information from multiple gateways to create decision trees, determining the optimal gateway based on service categories and performance parameters to register devices efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single gateway manages devices in conventional home networks, then device management is simple, but network coverage is limited and cannot support multi-gateway environments
Solution Approach 1:
The patent segments the device management function by introducing a master gateway that coordinates multiple slave gateways. Each gateway handles local device registration, while the master gateway performs centralized coordination through decision trees, dividing the management burden across multiple nodes to expand network coverage without overwhelming individual gateways
Solution Approach 2:
The master gateway acts as an intermediary between slave gateways and the external network. It receives device registration requests, evaluates multiple slave gateways using decision trees based on performance parameters, and directs devices to the optimal slave gateway, thereby managing the complexity of multi-gateway coordination centrally
2Area of stationary object
If multiple gateways are deployed to expand network coverage, then network coverage is improved, but the ability to detect the optimal gateway for device registration is lost
Solution Approach 1:
The master gateway performs preliminary actions by continuously collecting performance parameters from all slave gateways and pre-computing decision trees before device registration requests arrive. This advance preparation ensures that when a device needs registration, the optimal gateway is already identified based on current network conditions, preventing information loss about gateway suitability
Solution Approach 2:
The system implements feedback mechanisms where slave gateways continuously report their performance parameters (such as load, response time, and availability) to the master gateway. The master gateway uses this feedback to update decision trees and dynamically adjust gateway selections, ensuring that devices are always directed to the currently optimal gateway despite changing network conditions
3Productivity
If conventional registration methods are used in multi-gateway environments, then device registration can occur, but system performance is not optimized due to lack of optimal gateway detection
Solution Approach 1:
The patent changes the parameters used for gateway selection by evaluating multiple performance metrics (load, response time, availability) rather than using simple static criteria. The master gateway dynamically adjusts selection parameters based on real-time network conditions, allowing devices to be registered in gateways that currently offer the best performance, thereby optimizing both registration efficiency and system reliability
