Solution Overview

Problem

Current device-to-device (D2D) communication systems are limited by the use of fixed group IDs, which hinder adaptability in emergency situations and lead to communication delays and accessibility issues due to shared communication channels, making it difficult to dynamically respond to unexpected events.

Innovation Solution

A method and apparatus for creating dynamic groups in D2D communication, where user equipment (UEs) can generate and use dynamic group IDs based on their locations, allowing for flexible group formation and adaptation in response to changing situations, such as generating a dynamic group ID for a temporary group formed in response to an emergency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed group IDs are used in D2D communication, then group formation is simple, but adaptability to dynamic situations deteriorates

Engineering Contradiction:
ImproveadaptabilityVSAvoidgroup formation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transitioning from static fixed group IDs to dynamic group IDs that are generated in real-time based on current communication conditions, UE locations, and emergency situations. The group ID changes adaptively according to the dynamic state of the network and user needs, enabling the system to respond flexibly to changing situations while maintaining automated group formation through algorithmic generation.

Inventive Principle:
Principle #15Dynamics

2Productivity

If fixed group IDs are shared among multiple UEs, then resource utilization is efficient, but communication delays increase in emergency situations

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidcommunication delay
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies segmentation by dividing the communication system into multiple dynamic groups, each with its own unique group ID generated specifically for that group. Instead of all UEs sharing a single fixed group ID, the system segments UEs into separate dynamic groups based on location, emergency type, and communication needs, allowing parallel communication channels that reduce delays while maintaining efficient resource utilization across the network.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If dynamic group IDs are generated based on UE locations, then responsiveness to emergencies improves, but system complexity increases

Engineering Contradiction:
ImproveresponsivenessVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling UEs to autonomously generate their own dynamic group IDs based on their location information and the emergency situation without requiring centralized allocation from a base station or network controller. Each UE independently determines its group ID using local information and predefined algorithms, improving responsiveness to emergencies while avoiding the complexity of centralized dynamic ID management infrastructure.

Inventive Principle:
Principle #25Self-service
