Mobile Device Network Access Self-Healing via Limited Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices often face network connection failures due to invalid credentials or identifiers, leading to user inconvenience and increased interaction with customer service for troubleshooting.
Innovation Solution
The device activates an application to send an SMS message over an SMS control channel to diagnose the issue, performs a limited reset by replacing the invalid identifier with a factory default one, and attempts to re-establish network access using the factory default identifier, allowing self-correction and reducing customer service interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device performs a full reset to fix network access failure, then network connectivity is restored, but user data is lost
Solution Approach 1:
The patent applies partial reset action by performing a limited reset that only clears network access credentials and identifiers rather than executing a complete device reset. This selective approach restores network connectivity while preserving user data, avoiding the excessive action of a full factory reset that would delete all user information.
Solution Approach 2:
The reset process is segmented into specific components: network credentials, identifiers, and user data are handled separately. The system identifies and resets only the problematic network access elements while leaving other data intact, thereby restoring connectivity without data loss.
2Ease of operation
If the user manually troubleshoots network issues with customer service, then the problem is resolved, but time is spent on interaction
Solution Approach 1:
The system implements self-service by automatically diagnosing network access failures and executing appropriate reset procedures without requiring user intervention or customer service interaction. The device independently identifies credential issues, performs limited resets, and restores connectivity autonomously, eliminating time spent on manual troubleshooting.
Solution Approach 2:
The system uses feedback from network access attempts to automatically trigger diagnostic and corrective actions. When network access fails, the system receives feedback about the failure, analyzes it to determine credential-related issues, and automatically initiates the appropriate reset procedure based on the feedback received.
3Reliability
If the device attempts multiple network access methods, then network access success rate improves, but complexity of access procedures increases
Solution Approach 1:
The system dynamically adapts its access procedure based on real-time conditions. It attempts different network access methods (data connection, SMS control channel) in sequence, switching between them dynamically based on which method succeeds or fails, rather than following a fixed complex procedure regardless of conditions.
Solution Approach 2:
The SMS control channel serves as an intermediary access method when the primary data connection fails. The system uses this alternative channel to send test messages and establish network access through a different pathway, increasing success rate without requiring the user to understand or manage multiple complex procedures simultaneously.
Data Source
AI summary
A method of responding to a network connection failure in a mobile communication device. The method comprises receiving an error message indicating a data connection failure, activating an application configured to attempt to access the network using a first identifier on the mobile communication device in response to receiving the error message, sending an SMS message from the mobile communication device over an SMS control channel in an attempt to access the network, receiving information indicating a failure to access the network through the SMS control channel, determining that the failure to access the network is based on the first identifier, performing a limited reset of the mobile communication device to replace the first identifier with a factory default identifier, confirming through use of the factory default identifier that the first identifier is inactive, and establishing the factory default identifier such that the mobile communication device is configured for activation.
