Solution Overview

Problem

Current communication systems face challenges in determining and implementing wireless schemes efficiently, leading to increased system and network loads, and difficulties in storage and updating wireless scheme files, especially when multiple IoT service providers share a network.

Innovation Solution

A communication control device and system that acquires and stores setting files based on regional characteristics, allowing for dynamic determination and assignment of communication parameters, reducing the need for frequent downloads and optimizing storage capacity by caching only necessary files.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a wireless scheme file provided to the access point is managed by one management server, then the system can centrally control wireless schemes, but the system load and network load on the management server increase due to frequent downloads

Engineering Contradiction:

Improvecentralized control capabilityVSAvoidsystem load and network load

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent divides the management server into two parts: a setting file management server that stores and manages setting files, and a communication parameter management server that determines communication parameters. This segmentation allows the setting files to be cached locally at access points, reducing frequent downloads and network load on the central management system while maintaining centralized control capabilities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary caching of setting files at access points before they are needed for communication parameter determination. By storing setting files in advance at the edge devices (access points), the system avoids frequent real-time downloads from the central server, thereby reducing network load and improving response time.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If all wireless scheme files are stored in advance in the access point, then the access point can quickly determine communication parameters, but it becomes difficult to secure storage capacity and update files

Engineering Contradiction:

Improvecommunication parameter determination speedVSAvoidstorage management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements local caching of only the necessary setting files at each access point based on regional characteristics and communication conditions, rather than storing all possible wireless scheme files. This allows each access point to have customized local storage optimized for its specific operational context, improving determination speed while managing storage capacity efficiently.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent makes the setting file storage dynamic by allowing access points to cache setting files selectively based on their operational needs and regional characteristics. The cached files can be updated and refreshed as needed, providing flexibility in storage management while maintaining quick access to required parameters.

Inventive Principle:

Principle #15Dynamics

3Reliability

If wireless scheme files are frequently downloaded from the management server, then the access point can obtain updated schemes, but the system load and network load increase

Engineering Contradiction:

Improvewireless scheme update capabilityVSAvoidnetwork load

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements preliminary caching of setting files at access points before they are needed, rather than downloading them frequently in real-time. This reduces network load and bandwidth consumption while ensuring that updated files are available when needed for communication parameter determination.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates local copies of setting files at access points from the central management server. These copies are stored in a cache and used locally for communication parameter determination, reducing the need for frequent original file downloads and thereby reducing network load while maintaining update capability.

Inventive Principle:

Principle #26Copying

AI summary

A communication control apparatus includes a communication parameter acquisition unit that acquires at least one second communication parameter that is a candidate for a first communication parameter indicating a communication parameter to be assigned to a communication apparatus and indicates a communication parameter suitable for regional characteristics indicating a communication environment in a region where the communication apparatus is installed, a setting file storage unit that stores a setting file corresponding to each second communication parameter, a setting file acquisition control unit that acquires the setting file and stores the acquired setting file in the setting file storage unit, and a communication parameter assignment unit that determines the first communication parameter from among the second communication parameters acquired by the communication parameter acquisition unit and assigns the determined first communication parameter to the communication apparatus.
