Edge Computing Management Device for Roaming Data Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of data traffic in conventional LTE communication systems is not guaranteed due to distance and interworking network quality issues, particularly when providing data roaming services across different countries.
Innovation Solution
Implementing a data roaming service using an edge computing cloud (MEC cloud) that generates a virtual gateway in the visited network, allowing for the registration of access information and establishment of sessions between terminals and virtual gateways, thereby bypassing the need for data traffic to pass through the home network's PDN gateway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data traffic is routed through the home network's PDN gateway in conventional LTE systems, then interworking between home and visited networks is enabled, but data traffic quality deteriorates due to distance and interworking network conditions
Solution Approach 1:
The patent introduces a virtual gateway as an intermediary component deployed in the visited network's edge computing cloud. This virtual gateway mediates between the terminal in the visited network and the home network's PDN gateway, allowing data traffic to be routed locally through the edge computing cloud rather than directly through the distant home network infrastructure, thereby improving data traffic quality while maintaining network interworking capabilities
Solution Approach 2:
The patent adds a new dimensional layer to the traditional roaming architecture by deploying edge computing clouds in visited networks. This creates a multi-layered routing dimension where data traffic can choose between direct home network routing and local edge computing cloud routing, effectively adding a spatial dimension to traffic management that bypasses geographical distance constraints
2Reliability
If a virtual gateway is deployed in the visited network's edge computing cloud, then data traffic quality is improved by local routing, but device complexity increases due to additional virtual gateway infrastructure
Solution Approach 1:
The patent creates a virtual copy of the gateway functionality within the visited network's edge computing cloud. Instead of deploying entirely new physical gateway infrastructure, the solution virtualizes gateway functions and deploys them as software instances in the edge computing environment, reducing the complexity burden of additional hardware while maintaining the functional benefits of local routing
Solution Approach 2:
The virtual gateway deployed in the edge computing cloud serves multiple functions simultaneously: it acts as a local routing point for data traffic, provides network address translation, enables local breakout capabilities, and maintains session management functions. This multi-functionality consolidates what would otherwise require multiple separate components into a single unified virtual gateway, reducing overall system complexity
