Profile Modification Timeout Mechanism for Critical Situations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile modification methods in telecommunications networks are inefficient during critical situations, such as emergency calls, as they do not effectively manage profile changes and can lead to unnecessary exchanges between devices and microcircuits, wasting resources.
Innovation Solution
A method involving the reception of a request to deactivate a profile, followed by a timeout mechanism that ensures the profile remains active during critical situations, allowing emergency call centers to maintain connection data, and only deactivates the profile after a predetermined time has passed, thereby avoiding unnecessary profile activations and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the profile is deactivated immediately upon receiving a deactivation request, then the profile modification is completed quickly, but the device loses connectivity during critical situations such as emergency calls
Solution Approach 1:
The system performs a preliminary check by sending a first message to the device to verify if a critical situation exists before proceeding with profile deactivation. This preliminary action prevents premature deactivation that would compromise connectivity reliability during emergency calls or other critical situations.
Solution Approach 2:
The profile deactivation process is made dynamic through a timeout mechanism. If the device responds indicating a critical situation, the deactivation is delayed until the timeout expires, allowing the system to adapt its behavior based on real-time conditions rather than following a rigid immediate deactivation protocol.
2Reliability
If the system continuously checks for critical situations before profile modification, then connectivity reliability is maintained, but unnecessary exchanges between device and microcircuit increase energy consumption
Solution Approach 1:
The device itself is responsible for detecting and reporting its critical situation status to the microcircuit. Instead of the microcircuit continuously polling the device, the device autonomously monitors its own state and provides this information when queried, reducing unnecessary communication exchanges and energy consumption while maintaining connectivity reliability.
Solution Approach 2:
The system implements a feedback mechanism where the device responds to the first message by indicating whether a critical situation exists. This feedback allows the microcircuit to make informed decisions about profile deactivation timing, avoiding continuous checking while ensuring connectivity is maintained when needed.
3Productivity
If the profile is deactivated during an ongoing emergency call, then the profile modification is applied, but the emergency call center loses the ability to contact the device
Solution Approach 1:
Before deactivating the profile, the system sends a preliminary inquiry message to the device to check for ongoing emergency calls or other critical situations. This preliminary action ensures that profile modification does not proceed until it would be safe to do so, preventing loss of emergency communication capability.
Solution Approach 2:
The timeout mechanism acts as a cushioning measure that protects against premature profile deactivation. By introducing a time delay after detecting a critical situation, the system ensures that even if the device fails to respond or the situation persists longer than expected, the profile remains active long enough to maintain emergency communication reliability.

AI summary
The invention concerns a method for modifying the profile in a device (D) comprising a communication module for communicating on a communication network, the device (D) being provided with a microcircuit storing connection data used by the communication module and associated with a profile, characterised in that it comprises the following steps: reception, by the microcircuit and via the communication module, of a request to deactivate (E6) the profile; transmission, by the microcircuit, of a first message (E10) to the device (D); transmission, by the device (D) and to the microcircuit, of a response (E14) indicative of the existence of a critical situation; following the receipt of said response (E14) by the microcircuit, implementation of a time delay mechanism (E18); upon expiry of the time delay (E18), transmission, by the microcircuit and to the device (D), of a second message (E22) resulting in the deactivation of the profile.
