Solution Overview

Problem

Current 5G communication technologies fail to effectively manage and control security and privacy requirements for enterprise private networks, as existing network architectures rely on operator public networks for terminal device registration, subscription management, and security authentication, which cannot meet the specific needs of enterprise private networks.

Innovation Solution

A communication method and apparatus that enables a mobility management network element to receive information from a terminal device, obtain user equipment contexts in both public and private networks, and use this information to register the terminal device in both networks, allowing the private network to manage and control security and privacy data independently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the terminal device is registered only in the operator public network, then the network management is simplified, but the enterprise private network cannot independently manage security and privacy data

Engineering Contradiction:
Improvenetwork management complexityVSAvoidsecurity and privacy management
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the network management into two independent parts: the operator public network handles general connectivity, while the enterprise private network independently manages security and privacy data. This is achieved by allowing the terminal device to be registered in both networks separately, with the private network maintaining autonomous control over security authentication and subscription information management.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the terminal device is registered in both public and private networks, then security and privacy management is improved, but the network architecture complexity increases

Engineering Contradiction:
Improvesecurity and privacy managementVSAvoidnetwork architecture complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by enabling the terminal device to operate in both public and private networks simultaneously. The device maintains separate subscriptions and security contexts for each network type, allowing it to access public services while also connecting to private enterprise networks with appropriate security controls. This universal capability resolves the contradiction by making the device adaptable to multiple network environments without requiring separate hardware or complex configuration.

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

3Ease of operation

If the operator public network manages all terminal devices, then the network control is centralized, but the enterprise private network cannot meet specific security requirements

Engineering Contradiction:
Improvenetwork controlVSAvoidsecurity requirements adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by allowing different security management approaches for different network types. The operator public network maintains centralized control for general devices, while the enterprise private network implements localized security policies tailored to specific enterprise requirements. This is achieved through separate registration and authentication processes that enable the private network to enforce its own security rules independently.

Inventive Principle:
Principle #3Local quality
