Solution Overview

Problem

Wireless networks face heavy loads when continuously transmitting data to terminal apparatuses, leading to potential degradation in data distribution services due to inefficient data transmission management.

Innovation Solution

A communication control apparatus and method that acquires information on communication quality and accumulated data in terminal apparatuses, allowing for controlled data transmission to optimize network load and maintain service quality by adjusting transmission based on communication quality and data accumulation thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is continuously transmitted via wireless channels to terminal apparatuses, then data distribution service is maintained, but wireless network load becomes heavy

Engineering Contradiction:

Improvedata distribution serviceVSAvoidnetwork load

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The terminal apparatus accumulates data in advance before transmission is needed. The communication control apparatus transmits data to the terminal apparatus in advance and stores it in the terminal apparatus's buffer, so that when actual playback or processing is needed, the data is already available locally without requiring continuous network transmission.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of continuous transmission, the system uses periodic transmission where data is transmitted at specific intervals or when buffer levels indicate need. The communication control apparatus monitors buffer status and transmission quality, then schedules transmissions accordingly, reducing overall network load while maintaining service availability.

Inventive Principle:

Principle #19Periodic action

2Quantity of substance

If transmission of data via wireless channels is limited, then network load is reduced, but quality of data distribution service degrades

Engineering Contradiction:

Improvenetwork loadVSAvoiddata distribution service quality

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The communication control apparatus monitors transmission quality information from the wireless channel and buffer status information from the terminal apparatus, then adjusts transmission decisions based on this feedback. When transmission quality is good and buffer has sufficient data, transmission is paused to reduce network load. When buffer is low or transmission quality degrades, transmission resumes to maintain service quality.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically changes transmission parameters such as transmission timing, data amount per transmission, and transmission frequency based on real-time conditions including network load, buffer status, and channel quality. This allows optimization of both network load reduction and service quality maintenance.
