Edge Control Device for Low Latency Virtual Core Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reduce latency in virtual core networks, particularly in 5G systems, where constructing a virtual core network across different networks via the Internet may not adequately meet the demand for low latency, especially when the base station device and cloud server are not geographically close.
Innovation Solution
A control device that connects to multiple processing devices and a base station via a network, acquiring information on processing capabilities and selecting the optimal processing device to execute core network functions based on latency and processing quality, ensuring lower latency by strategically placing virtual core network components.

Engineering Contradiction Analysis
1Loss of energy
If a virtual core network is constructed across different networks via the Internet in a data center of a cloud service provider, then cost reduction is achieved, but latency cannot be sufficiently reduced to meet URLLC requirements
Solution Approach 1:
The patent applies local quality by deploying virtual core network functions at edge locations closer to base stations rather than centralized cloud data centers. This creates different service quality levels: standard services use centralized cloud infrastructure for cost efficiency, while URLLC services use edge-located virtualized functions for low latency. The network dynamically selects the appropriate deployment location based on service requirements.
Solution Approach 2:
The patent introduces a new spatial dimension to network architecture by adding edge computing nodes between centralized cloud data centers and base stations. This creates a multi-tier deployment model (cloud-edge-base station) that allows simultaneous optimization for both cost (centralized cloud) and latency (edge proximity) by selecting the appropriate tier for each service type.
2Device complexity
If virtual core network functions are deployed in centralized cloud data centers, then device complexity is reduced, but latency increases due to geographical distance from base stations
Solution Approach 1:
The patent segments the virtual core network into multiple independent instances that can be deployed at different locations. Instead of a single centralized deployment, the system creates separate virtual network function instances at edge locations and centralized cloud locations, allowing independent optimization of each instance for its specific deployment context and service requirements.
Solution Approach 2:
The patent implements dynamic selection of virtual network function deployment locations based on real-time service requirements. The system can dynamically route traffic to edge-located functions when low latency is needed and to centralized cloud functions when cost efficiency is prioritized, making the network architecture adaptable rather than static.
3Loss of time
If multiple virtual core network instances are deployed at edge locations, then latency is reduced, but device complexity and management difficulty increase
Solution Approach 1:
The patent creates a universal orchestration platform that can manage multiple virtual network function instances across different deployment locations (edge and cloud) through a single interface. This multi-functional management system handles provisioning, configuration, monitoring, and lifecycle management uniformly regardless of where the virtualized functions are physically deployed, abstracting away the complexity from operators.
