Remote Device Reconfiguration via Action Request Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face performance issues, such as corrupted service identifiers, which prevent communication service registration, and lack an effective method for remote reconfiguration with user consent, requiring users to visit phone stores or send devices for repair.
Innovation Solution
A communication system that determines an action request message for a software operating system, associates it with a URI, and prompts the user for input to process the message, allowing remote reconfiguration of devices by translating the URI into display data and executing actions within the operating system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service identifier is stored in locked manner for security, then security is improved, but device becomes unrepairable when identifier is corrupted
Solution Approach 1:
The patent introduces an intermediary mechanism (unlock code stored in secure element) that mediates between the locked service identifier and the need for repair. The secure element acts as a trusted intermediary that can verify identity and authorize configuration changes without exposing the locked service identifier, enabling repair while maintaining security.
Solution Approach 2:
The patent implements preliminary action by pre-storing unlock codes in the secure element before the service identifier becomes corrupted. This preliminary preparation allows the device to be unlocked and reconfigured later when needed, without requiring physical access or service center intervention at the time of repair.
2Reliability
If user must visit phone store for repair, then security is maintained, but user convenience deteriorates
Solution Approach 1:
The patent enables self-service by allowing users to unlock and reconfigure their own devices using credentials (unlock codes) that are already stored in their secure elements. Users can perform repairs themselves through automated processes without needing to visit physical stores or wait for service center appointments, thus improving convenience while maintaining security through the use of stored credentials.
3Reliability
If service provider does not provide unlock codes to users, then security is improved, but repair efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by having service providers pre-load unlock codes into users' secure elements during initial device provisioning or previous service interactions. This preliminary action eliminates the need for service providers to manually provide codes during repair, enabling immediate self-service repairs while maintaining the security of not distributing codes through conventional channels.
Data Source
AI summary
In a communication system, a device control system determines an action request message for a software operating system in a user communication device and associates the action request message with a URI. A user communication device displays a prompt for the URI, receives a user input to prompt, and transfers a request for the URI responsive to the user input. The device control system receives the URI and responsively transfers display data indicating the action request message. The user communication device receives the display data, displays a user prompt, receives another user input, and processes the action request message in the software operating system responsive to the other user input.
