Solution Overview

Problem

Conventional D2D communication systems lack management capabilities for data transmission and reception without routing via a base station, making it difficult for network nodes to monitor or manage such data exchanges.

Innovation Solution

A communication apparatus that generates and transmits data-related information, including charging and lawful interception details, to a management node, enabling effective management of wireless communication without relying on base station routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is transmitted directly between terminals without routing via a base station, then communication efficiency is improved, but network management capability deteriorates

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidnetwork management information
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent segments information into two categories: data for communication (transmitted directly between terminals) and data-related information (transmitted to network nodes). This segmentation allows direct terminal-to-terminal communication while separately managing network oversight, resolving the contradiction between communication efficiency and management capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces data-related information as an intermediary element that carries metadata about direct communications to network nodes. This intermediary mechanism enables network management without requiring actual communication data to route through base stations, maintaining both efficiency and manageability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If data is transmitted directly between terminals without routing via a base station, then transmission speed is improved, but billing management capability deteriorates

Engineering Contradiction:
Improvetransmission speedVSAvoidbilling information
Core Design Contradiction:
SpeedVSLoss of information

Solution Approach 1:

The patent segments information into communication data (transmitted directly at high speed) and billing-related information (transmitted to network nodes). This allows fast direct transmission while maintaining billing capability through separate metadata reporting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Data-related information acts as an intermediary that conveys billing-relevant metadata to network nodes without requiring actual communication data to pass through the network infrastructure, preserving both speed and billing management.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If data is transmitted directly between terminals without routing via a base station, then communication flexibility is improved, but lawful interception capability deteriorates

Engineering Contradiction:
Improvecommunication flexibilityVSAvoidinterception information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments communication into direct data transmission (flexible and autonomous) and separate reporting of data-related information (enabling lawful interception). This dual-path approach maintains flexibility while preserving security oversight capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Data-related information serves as an intermediary mechanism that enables lawful interception by providing metadata about direct communications to authorized network nodes, without constraining the flexibility of actual data transmission between terminals.

Inventive Principle:
Principle #24Intermediary (Mediator)
