Innovation Solution

A method and system that utilize a clean-slate radio approach with a new air interface for IoT applications, integrating IoT devices with cellular networks using radiofrequency electromagnetic signals, allowing for efficient transmission of small and infrequent data without unnecessary resource management, and using unlicensed or licensed spectrum for low-energy operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If existing cellular mobile communication networks are used for IoT data transmission, then compatibility with existing infrastructure is maintained, but power consumption increases and transmission efficiency decreases

Engineering Contradiction:
Improvepower consumptionVSAvoidcompatibility with existing infrastructure
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent introduces a specialized IoT base station entity that acts as an intermediary between existing cellular infrastructure and IoT devices. This intermediary handles small data transmissions using optimized protocols while interfacing with the core network, thereby reducing power consumption for IoT devices without sacrificing compatibility with existing cellular infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the cellular network functionality by introducing a dedicated IoT base station entity separate from traditional mobile base stations. This segmentation allows IoT-specific optimizations (lower power consumption, simplified protocols) to be applied to small data transmissions while the core network maintains existing compatibility with traditional mobile services.

Inventive Principle:
Principle #1Segmentation

2Productivity

If optimized protocols for small data transmission are implemented, then transmission efficiency improves, but device complexity increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidprotocol complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts complex protocol handling and resource management functions from the IoT device and relocates them to the base station entity. The device only needs to implement simple transmission protocols, while the base station handles scheduling, resource allocation, and core network interfacing, thereby improving transmission efficiency without significantly increasing device complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The base station entity provides self-service by automatically managing resource allocation, scheduling, and protocol adaptation for IoT devices. This eliminates the need for complex device-side protocol implementations, as the base station autonomously handles optimization while maintaining simple device architecture.

Inventive Principle:
Principle #25Self-service

3Reliability

If dedicated IoT communication resources are allocated, then transmission reliability improves, but network resource utilization decreases

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidnetwork resource utilization
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements dynamic resource allocation where the base station entity adaptively assigns communication resources to IoT devices based on actual transmission needs. Resources are allocated on-demand for small data transmissions and released when not needed, ensuring reliable communication when required while maximizing overall network resource utilization through flexible, non-static allocation.

Inventive Principle:
Principle #15Dynamics
