Gateway Device Configuration via Announcement Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of configuring terminal devices by a gateway is complex and inefficient due to the need for periodic device discovery and information retrieval, which complicates the interaction between the gateway and the terminal device.
Innovation Solution
A method and apparatus that utilize a device announcement message carrying terminal device information to simplify the interaction process by determining if the terminal device needs configuration based on the received information, and sending configuration information accordingly, optimizing the configuration process by matching rules and service configuration identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gateway performs periodic device discovery and information retrieval to configure terminal devices, then the terminal device can be configured and managed, but the configuration process becomes complex and efficiency decreases
Solution Approach 1:
The terminal device performs self-detection and prepares configuration information in advance by sending device announcement messages containing device information and service configuration identifiers. This preliminary action eliminates the need for the gateway to perform complex periodic discovery and information retrieval, thereby improving configuration efficiency while maintaining reliable device configuration.
2Loss of information
If the gateway sends multiple UPnP query commands to obtain terminal device information, then comprehensive device information can be obtained, but the interaction process becomes complex
Solution Approach 1:
The terminal device merges multiple pieces of information (device information, service configuration identifiers, and current configuration status) into a single device announcement message. This consolidation allows the gateway to obtain comprehensive device information through a single interaction rather than multiple UPnP query commands, significantly reducing interaction process complexity while maintaining information completeness.
3Adaptability or versatility
If the gateway performs device discovery and configuration every time a device announcement message is received, then the terminal device can be configured when needed, but the configuration process is triggered frequently and reduces efficiency
Solution Approach 1:
The terminal device provides feedback information in the device announcement message, including service configuration identifiers and current configuration status. The gateway uses this feedback to intelligently determine whether configuration is needed by comparing the provided configuration identifier with stored records. This feedback mechanism maintains configuration timing flexibility while avoiding unnecessary configuration operations, thereby improving overall configuration efficiency.
