Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for managing communication profiles in mobile devices fail to distinguish between current and outdated deactivation requests, leading to potential erroneous deactivation of the profile.

Innovation Solution

Implementing an identifier system where mobile devices and external entities can store and match activation identifiers to ensure that only current deactivation requests are executed, preventing accidental deactivation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If deactivation requests are transmitted without identifiers, then the system is simple and easy to operate, but outdated deactivation requests cannot be distinguished from current ones leading to erroneous deactivation

Engineering Contradiction:

Improveaccuracy of deactivation executionVSAvoidcomplexity of deactivation request system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

An identifier is generated and stored in advance when a mobile device activates a communication profile. This identifier is attached to deactivation requests sent to external parties, enabling the receiving device to verify whether a deactivation request is current or outdated by comparing identifiers. This preliminary action prevents erroneous deactivation without requiring complex real-time verification mechanisms.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback mechanism where deactivation requests include identifiers that reference the activation state. The receiving mobile device uses this identifier feedback to determine whether to execute deactivation, creating a closed-loop verification system that ensures reliability while maintaining simplicity.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If multiple mobile devices share the same communication profile, then resource utilization is improved, but synchronization issues occur when devices fall outside network range leading to profile activation conflicts

Engineering Contradiction:

Improveability to share communication profileVSAvoidsynchronization of profile activation state

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

When a mobile device activates a communication profile, it generates and stores an identifier in advance. This identifier is subsequently used in deactivation requests to prove the device's current authorization status. This preliminary identifier generation enables reliable profile sharing among multiple devices while preventing synchronization conflicts, as each device can verify its authority to deactivate using its stored identifier.

AI summary

A method for controlling a mobile terminal comprises the following steps: activating a communication profile of the terminal; transmitting a notification about the activation to an external location; storing an identifier for the activation; receiving a deactivation request and an identifier; and deactivating the communication profile if the identifier received corresponds to the identifier stored.
