Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio-based networks face challenges in efficiently deploying and managing virtual private clouds (VPCs) for user equipment, leading to high costs, complexity, and limited flexibility in meeting quality-of-service (QoS) requirements, especially with the transition to 5G networks.
Innovation Solution
Extending cloud-based virtual private networks to user equipment on radio-based networks by decoupling hardware from software, enabling network slicing, and using cloud-native microservices to manage network functions, allowing seamless integration of user equipment with VPCs through tunneling and packet encapsulation, and providing APIs for management and scalability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If virtual private clouds are deployed on radio-based networks using traditional methods, then network connectivity is provided, but deployment costs and complexity increase significantly
Solution Approach 1:
The patent introduces a network gateway as an intermediary component that bridges the radio-based network and the virtual private cloud network. This gateway handles protocol conversion, authentication, and traffic routing, thereby simplifying the deployment process for user equipment while managing the underlying system complexity within the gateway itself rather than across the entire system.
Solution Approach 2:
The system implements feedback mechanisms through network slicing management that monitors QoS parameters and dynamically adjusts resource allocation. This feedback loop enables automated optimization of network performance, reducing manual configuration complexity and lowering deployment costs through self-adjusting network parameters based on real-time conditions.
2Reliability
If traditional VPC deployment methods are used on radio-based networks, then basic connectivity is achieved, but QoS requirements for applications like IoT and augmented reality cannot be met
Solution Approach 1:
The patent implements network slicing that divides the radio-based network into multiple virtual networks, each optimized for specific QoS requirements. Different slices can be configured for different application types (e.g., low-latency slice for augmented reality, high-throughput slice for IoT), ensuring reliable QoS delivery without requiring complex end-to-end configuration for each application.
Solution Approach 2:
The system dynamically changes network parameters such as bandwidth allocation, latency thresholds, and priority levels based on the specific QoS requirements of different network slices and applications. This parameter adjustment capability enables the network to meet diverse QoS demands while maintaining manageable configuration complexity through centralized control.
3Adaptability or versatility
If cloud-based VPCs are extended to user equipment on radio-based networks, then flexibility and cost-effectiveness improve, but integration complexity increases
Solution Approach 1:
The network gateway is designed as a universal interface that handles multiple functions including authentication, encryption, protocol conversion, and traffic routing for different types of user equipment and applications. This multi-functional design provides deployment flexibility across diverse scenarios while consolidating integration complexity within the gateway rather than requiring custom integration for each device type.

AI summary
Disclosed are various embodiments for extending cloud-based virtual private networks to user equipment on radio-based networks. In one embodiment, a request is received from a client device for service from a radio-based network. The client device is provided with access to a virtual private cloud network through the radio-based network in response to receiving the request from the client device for service from the radio-based network. Encapsulated network traffic is forwarded from the client device to the virtual private cloud network via a network link between the radio-based network and a cloud provider network that hosts one or more resources on the virtual private cloud network.
