Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for efficient zero-trust connectivity solutions for Subscriber Identity Module (SIM) enabled equipment to securely forward traffic from devices to cloud-based systems, avoiding backhauling through corporate data centers and ensuring secure access to cloud services, especially in the context of growing remote work and IoT devices.
Innovation Solution
The implementation of cloud-based 5G security network architectures that integrate cloud-based security services within Multiaccess Edge Compute (MEC) systems, utilizing SIM cards, eSIM, or iSIM for intelligent steering and secure edge computing, enabling secure traffic forwarding and access control through cloud edge gateways and enforcement nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic is backhauled through corporate data centers, then centralized security control is maintained, but network latency increases and productivity decreases
Solution Approach 1:
The patent segments the network architecture by deploying cloud-based security services at the edge (MEC nodes) rather than centralizing all security control in a remote data center. This allows traffic to be processed locally at the edge for faster response while maintaining centralized policy control through the cloud, resolving the contradiction between security control and network efficiency.
Solution Approach 2:
The patent introduces cloud-based security services as an intermediary between edge devices and the corporate data center. These services act as a mediator that provides security functions at the edge while maintaining connectivity to the cloud for policy enforcement, eliminating the need for traffic backhauling while preserving security control.
2Reliability
If all traffic is forwarded to cloud-based system, then security coverage is improved, but device complexity and network overhead increase
Solution Approach 1:
The patent implements self-service by allowing devices to automatically establish connections to cloud-based security services through standardized protocols. The cloud system automatically provisions security services, enforces policies, and manages traffic routing without requiring complex local configuration, thereby improving security coverage while minimizing device complexity.
Solution Approach 2:
The patent creates a universal cloud-based security service platform that can serve multiple device types and network scenarios through a single standardized interface. This multi-functional approach allows diverse devices to access security services uniformly, reducing the complexity of configuring different security solutions for different devices.
3Ease of operation
If SIM cards are pre-provisioned with network routing, then connectivity is simplified, but adaptability to different networks is reduced
Solution Approach 1:
The patent implements dynamics by allowing SIM cards to be pre-provisioned with default routing to cloud-based security services, while maintaining the ability to dynamically adapt to different networks and scenarios. The cloud-based system can modify routing decisions based on real-time conditions, device location, and network availability, thereby preserving adaptability despite pre-provisioning.
