Innovation Solution

Implementing a unified data management system to prioritize NB-IoT device connectivity based on service categories, dynamically reconfiguring virtual UICC authentication and encryption resources, and managing encryption keys of different strengths to optimize network resource usage and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a unified data management system is implemented to prioritize NB-IoT device connectivity based on service categories, then network resource allocation efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvenetwork resource allocation efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic reconfiguration of virtual UICC authentication and encryption resources based on service categories and device capabilities. The network can adjust resource allocation in real-time, transitioning from static to dynamic management, which improves network resource allocation efficiency without requiring permanent increases in device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes parameters such as encryption key strength and authentication resource allocation based on service categories. By adjusting these parameters dynamically rather than maintaining fixed high-level configurations, the system improves overall network efficiency while keeping individual device requirements manageable

Inventive Principle:
Principle #35Parameter changes

2Reliability

If dynamic reconfiguration of virtual UICC authentication and encryption resources is performed, then security is improved, but use of energy increases

Engineering Contradiction:
ImprovesecurityVSAvoiduse of energy
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies different authentication and encryption resource levels to different service categories and device capabilities. Instead of uniformly high security across all devices, the system provides locally optimized security levels - stronger authentication for critical services, weaker for less critical ones - thereby improving overall security posture while reducing energy consumption for devices that don't require maximum security

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs partial reconfiguration of security resources based on actual needs. Rather than continuously maintaining maximum security levels for all devices, it applies security measures proportionally to service requirements, achieving adequate security while minimizing unnecessary energy expenditure

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If encryption keys of different strengths are managed, then adaptability is improved, but device complexity increases

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

Solution Approach 1:

The patent implements a universal key management system that handles multiple key strengths through a single standardized interface and protocol. The network manages the complexity of different key strengths centrally, while devices interact through a unified mechanism, thereby achieving adaptability across different service requirements without proportionally increasing device complexity

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

AI summary

A method to configure a virtual integrated universal integrated circuit card (UICC) that is integrated in a narrowband Internet-of-Things (NB-IoT) host device of a telecommunications network. One or more network nodes can configure one or more authentication and encryption functions for the UICC based on a capability of the NB-IoT device and a condition of the 5G network. The network node(s) can detect a change in a condition of the network or the capability of the NB-IoT device and, in response, reconfigure the UICC for one or more second authentication and encryption functions.
