Solution Overview

Problem

Existing communication device profile setting technologies are inefficient when interrupted for long periods, leading to wasted resources and inability to restart profile setting after a predetermined number of retries.

Innovation Solution

A communication control device with a control unit, communication unit, and storage unit that sets a trigger for profile setting based on device information, retries setting the profile multiple times, and resets the trigger if unsuccessful, allowing for resumed profile setting when the device becomes communicative.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the profile setting process is retried indefinitely after interruption, then the profile can be set successfully when the device becomes communicative, but communication resources are wasted and management costs increase

Engineering Contradiction:
Improveprofile setting completionVSAvoidcommunication resource waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent changes the parameter of retry behavior from indefinite retry to limited retry with trigger reset. The control unit resets the trigger after a predetermined number of unsuccessful retries, preventing continuous retry attempts and conserving communication resources while still allowing profile setting to resume when conditions improve.

Inventive Principle:
Principle #35Parameter changes

2Loss of energy

If the trigger is not reset after unsuccessful retries, then communication resources are conserved, but profile setting cannot be restarted when the device becomes communicative

Engineering Contradiction:
Improvecommunication resource conservationVSAvoidprofile setting restart capability
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The patent makes the retry trigger dynamic by resetting it after a predetermined number of unsuccessful retries. This allows the system to adapt between conservative resource management (limiting retries) and flexible profile setting (allowing restart when communicative), optimizing behavior based on actual conditions.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the profile setting process is interrupted for a long period, then the device may be stored in a non-communicative state, but continuous retry attempts increase system complexity and resource consumption

Engineering Contradiction:
Improveprofile setting completion after interruptionVSAvoidretry management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent establishes a predetermined number of retry attempts as a preliminary constraint before profile setting interruption occurs. This pre-defined limit simplifies the retry management logic by eliminating the need for complex indefinite retry mechanisms, while still providing sufficient attempts for profile setting to complete when the device becomes communicative.

Inventive Principle:
Principle #10Preliminary action

AI summary

A communication control device according to one embodiment of the present invention includes: a storage unit configured to store conditions for setting a profile used by a communication device for communication; a profile setting unit configured to start to set the profile for the communication device in a case in which a signal received from the communication device satisfies the conditions stored in the storage unit; and a condition setting unit configured to invalidate the conditions stored in the storage unit in a case in which the profile setting unit starts to set the profile and configured to validate conditions for setting a profile used by the communication device for communication in a case in which the profile setting unit has failed in setting the profile.
