Solution Overview

Problem

In next-generation mobile communication systems with spot networks, fluctuating communication delays between terminal devices connected to different networks make it difficult to synchronize data transmission, especially when intermittent reception is involved.

Innovation Solution

An information processing device acquires information from an application server and notifies base station devices of setting information regarding intermittent reception using an application programming interface (API), aligning the timing of intermittent reception to suppress delay fluctuations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If intermittent reception is used to reduce power consumption, then energy efficiency is improved, but communication delay fluctuation increases

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication delay stability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The base station device receives feedback information about the terminal device's intermittent reception settings from the information processing device, and uses this feedback to adjust transmission timing and parameters, thereby maintaining communication reliability while preserving power savings from intermittent reception

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts the intermittent reception parameters and transmission timing based on real-time communication conditions, allowing the terminal device to maintain synchronized communication with the server while optimizing power consumption through adaptive intermittent reception patterns

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple terminal devices communicate with the server simultaneously, then system functionality is improved, but synchronization difficulty increases

Engineering Contradiction:

Improvesystem functionalityVSAvoidsynchronization complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The information processing device performs preliminary actions by acquiring information about each terminal device's intermittent reception settings before communication begins, and notifies the base station device of these settings in advance, enabling the system to pre-calculate and coordinate synchronized transmission timing for multiple devices

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system segments the synchronization management task by having the information processing device collect and process individual terminal device information separately, then synthesize this information to generate coordinated transmission schedules for multiple devices, thereby reducing overall synchronization complexity

Inventive Principle:

Principle #1Segmentation
