SMS Gateway for Automated Wi-Fi Troubleshooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi networks in mission-critical applications face connectivity issues such as outages, slow bandwidth, and user device identification complexities, making it difficult to report problems and requiring live operators, which increases support expenses.
Innovation Solution
A system that uses SMS messages with MAC addresses to report connectivity issues, converts them via a network manager API, retrieves error logs to determine solutions, and sends solutions back to users via SMS, with follow-up messages to assess effectiveness and log successes/failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If telephone support is used to report connectivity issues, then user support is provided, but it is difficult to identify user devices by MAC number and requires live operators 24-hours a day, increasing support expenses
Solution Approach 1:
The patent replaces the mechanical/voice-based telephone support system with an automated SMS-based system. Users send SMS messages containing their MAC addresses to report connectivity issues, and an automated system processes these messages without requiring live operators. This substitution eliminates the complexity of voice-based MAC address identification and removes the need for 24-hour human operator coverage.
2Reliability
If live operators are deployed for 24-hour support, then user connectivity issues can be resolved, but support expenses increase
Solution Approach 1:
The patent implements a self-service system where users independently report connectivity issues via SMS with their MAC addresses. The automated network manager processes these reports, retrieves error logs, determines solutions, and sends back connectivity solutions without human intervention. This self-service approach maintains 24-hour support availability while eliminating the need for paid live operators, thereby reducing support expenses.
Solution Approach 2:
The patent introduces an automated SMS gateway and network manager as intermediaries between users and the support system. These intermediaries automatically receive SMS messages, process MAC addresses, query error logs, determine solutions, and communicate back to users. This intermediary layer provides 24-hour support functionality without requiring human operators, thus maintaining reliability while reducing expenses.
3Ease of operation
If network connectivity is unavailable, then users cannot report problems, but connectivity issues still occur
Solution Approach 1:
The patent uses SMS messaging as an intermediary communication channel that operates independently of the Wi-Fi network being diagnosed. Since SMS uses cellular networks rather than the problematic Wi-Fi connection, users can report connectivity issues even when the Wi-Fi network is unavailable. The SMS gateway acts as a mediator that receives problem reports through an alternative communication path.
Solution Approach 2:
The patent shifts the communication dimension from Wi-Fi-based data communication to cellular SMS communication. By moving the problem reporting mechanism to a different communication dimension (cellular network instead of Wi-Fi network), users maintain the ability to report issues even when the primary Wi-Fi connectivity is down, thus preserving the ability to report problems independent of network availability.

AI summary
Wi-Fi connectivity issues are automatically resolved over SMS. An SMS message including a MAC address is received for a station having a wireless connectivity issue involving a Wi-Fi portion of the data communication network. The SMS message is converted according to an API (application programming interface) of the network manager. Error logs are retrieved according to the MAC address. Based on the error logs, a connectivity solution (or other type of solution) to the connectivity issue is determined. The connectivity solution from the network manager API to an SMS message. The SMS message with the connectivity solution is sent to the station. Subsequent SMS messages are sent to the station to determine whether the connectivity solution was effective in improving a client experience.
