Solution Overview

Problem

As services diversify, there is a growing need to reduce communication costs while maintaining service quality, which existing wireless communication systems struggle to achieve effectively.

Innovation Solution

A wireless communication device and system that dynamically route data through cellular MBB, cellular BDT, and wireless LAN based on data priority, using a routing control mechanism to select the most cost-effective and real-time suitable network for transmission, with the communication device equipped with a storage section, communication section, acquisition section, routing control section, and communication state monitoring section to manage and prioritize data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If data is transmitted through cellular MBB to ensure high real-time performance, then service quality is maintained, but communication cost increases

Engineering Contradiction:
Improvereal-time performanceVSAvoidcommunication cost
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The patent segments data into different priority levels (high priority and low priority) and routes them through different networks accordingly. High priority data uses cellular MBB for real-time performance, while low priority data uses cellular BDT or wireless LAN to reduce communication cost.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The routing control section dynamically selects the optimal network based on real-time conditions including data priority, network availability, and communication cost. The system adapts its routing decisions dynamically rather than using fixed routes.

Inventive Principle:
Principle #15Dynamics

2Loss of energy

If data is transmitted through cellular BDT or wireless LAN to reduce communication cost, then cost is reduced, but real-time performance deteriorates

Engineering Contradiction:
Improvecommunication costVSAvoidreal-time performance
Core Design Contradiction:
Loss of energyVSSpeed

Solution Approach 1:

The patent segments data into different priority levels and routes them through different networks. Low priority data is transmitted through cost-effective networks like cellular BDT or wireless LAN, while high priority data uses cellular MBB, thereby achieving cost reduction without compromising critical real-time performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different network qualities are assigned to different data types based on their priority and requirements. The system applies appropriate network characteristics locally to each data stream rather than using a uniform network for all data.

Inventive Principle:
Principle #3Local quality

3Loss of energy

If multiple networks are used to optimize cost and performance, then communication cost is reduced and service quality is maintained, but device complexity increases

Engineering Contradiction:
Improvecommunication costVSAvoidrouting control complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The wireless communication device is designed with multi-functionality to handle multiple network types (cellular MBB, cellular BDT, wireless LAN) and automatically select the optimal network based on predefined criteria. The routing control section consolidates network management functions in a centralized manner.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs automatic network selection and routing decisions autonomously based on data priority, network availability, and cost considerations. The routing control section makes self-directed decisions without external intervention, reducing the need for complex manual configuration.

Inventive Principle:
Principle #25Self-service
