Home Gateway Fault Diagnosis via Terminal Wireless Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fault diagnosis methods for home gateway devices are inefficient, relying heavily on operators and manual interventions, leading to delayed and costly diagnostics, especially when a large number of devices require maintenance, and often fail to provide accurate and timely results.
Innovation Solution
A fault diagnosis method and system that enables a terminal to establish a wireless connection with a home gateway device for local fault diagnosis, with the option to switch to a remote connection via a Network Management System (NMS) if local connection fails, allowing the terminal to send and receive diagnosis requests and results, and perform network tests to verify configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual diagnosis by technicians is used, then diagnosis accuracy can be improved, but diagnosis efficiency deteriorates due to large quantity of devices and high operational costs
Solution Approach 1:
The home gateway device autonomously performs fault diagnosis by executing diagnosis requests received from terminals directly at the device level, eliminating the need for technician intervention. The device self-diagnoses by running diagnostic programs locally and returning results to users, achieving both accuracy and efficiency through automated self-service diagnosis
Solution Approach 2:
A terminal device acts as an intermediary between users and the home gateway device, enabling users to initiate diagnosis requests and receive results without directly interacting with the gateway or requiring technician involvement. The terminal mediates the diagnosis process by communicating with the gateway and presenting results to users in an understandable format
2Adaptability or versatility
If remote connection via NMS is used, then diagnosis coverage can be improved for all devices, but system complexity and operational costs increase
Solution Approach 1:
The diagnosis system is segmented into two independent pathways: local diagnosis through direct terminal-gateway connection and remote diagnosis through NMS. This segmentation allows the system to handle different diagnosis scenarios through appropriate pathways, reducing overall system complexity while maintaining comprehensive coverage
Solution Approach 2:
The system dynamically selects the diagnosis pathway based on connectivity conditions - attempting local diagnosis first, and automatically switching to remote NMS diagnosis if local connection fails. This dynamic adaptability ensures comprehensive coverage while keeping the system flexible and manageable
3Speed
If local wireless connection is established, then diagnosis speed is improved, but connection reliability may deteriorate in certain network conditions
Solution Approach 1:
The system prepares alternative diagnosis pathways in advance by having both local and remote connection mechanisms ready. If local wireless connection fails, the system has pre-configured remote NMS connection as a backup, cushioning against connection failures and ensuring diagnosis can proceed through alternative means

AI summary
A fault diagnosis method includes establishing a wireless connection with a home gateway device in a local area network, if the wireless connection is successfully established, sending a diagnosis request to the home gateway device such that the home gateway device performs fault diagnosis, and receiving a fault diagnosis result returned by the home gateway device. After successfully establishing a wireless connection with a home gateway device in a local area network, a terminal sends a diagnosis request to the home gateway device to trigger the home gateway device to perform fault diagnosis.
