Solution Overview
Problem
Existing communication systems lack the ability to provide a communication service tailored to the specific network type to which a terminal is connected, such as non-3GPP and 3GPP access networks, limiting flexibility and efficiency in service provision.
Innovation Solution
A data center system that includes a virtual core network capable of virtualizing core network functions and selectively controlling services based on the network connection type, allowing terminals to choose between a base station or wireless LAN for connectivity, with integrated packet filtering and QoS management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal connects to a core network through a base station or wireless LAN, then communication service is provided, but the system cannot adapt services to different network types
Solution Approach 1:
The core network functions are segmented into virtualized network functions (VNFs) that can be independently deployed and managed. This segmentation allows the system to selectively activate specific network functions based on the terminal's connection type (base station or wireless LAN), enabling service adaptation without increasing overall system complexity.
Solution Approach 2:
The patent implements a universal service gateway that can handle multiple types of network connections (both base station and wireless LAN) through a single unified interface. This multi-functional gateway adapts services dynamically based on the connection type, eliminating the need for separate dedicated systems for each network type.
2Productivity
If core network functions are virtualized, then flexibility and efficiency are improved, but system complexity increases
Solution Approach 1:
Multiple virtualized network functions are merged into a unified virtual core network architecture that shares common infrastructure resources. This consolidation improves productivity by efficient resource utilization while managing complexity through a unified management plane that orchestrates all VNFs centrally.
Solution Approach 2:
The patent introduces a service gateway as an intermediary layer between the virtualized network functions and external networks. This mediator simplifies complexity by providing a standardized interface that abstracts the underlying virtualization complexity, allowing efficient service provision without exposing the full complexity of the virtualized architecture.
3Adaptability or versatility
If services are selectively controlled based on network connection type, then charging and QoS are optimized, but control complexity increases
Solution Approach 1:
The service gateway implements dynamic service control that automatically adjusts network parameters, charging policies, and QoS settings based on the detected connection type. This dynamic adaptation enables optimized charging and QoS for different networks without manual intervention, managing control complexity through automated decision-making algorithms.
Solution Approach 2:
The system incorporates feedback mechanisms where the service gateway continuously monitors connection type and network conditions, then adjusts service parameters accordingly. This closed-loop control optimizes charging and QoS based on real-time information while managing complexity through automated feedback-driven adjustments rather than complex manual control mechanisms.
