Virtual Core Network Service Control for Dual Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems struggle to provide a unified communication service that adapts to different types of access networks, such as 3GPP and non-3GPP networks, without requiring separate infrastructure and billing systems for each type.
Innovation Solution
A communication system that includes a data center with a virtual core network capable of virtualizing core network functions and a control unit to dynamically control services based on the connected network type, allowing terminals to select between wireless LAN and base station connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate infrastructure and billing systems are implemented for each access network type (3GPP and non-3GPP), then service reliability and network management are improved, but device complexity and infrastructure costs increase
Solution Approach 1:
The patent merges 3GPP and non-3GPP access networks into a unified core network architecture where both access types connect to common network functions (MME, SGW, PGW). This consolidation reduces infrastructure complexity while maintaining service reliability through standardized interfaces and unified billing systems, eliminating the need for separate infrastructure for each access network type.
Solution Approach 2:
The core network components are designed with universal functionality to handle both 3GPP and non-3GPP access types. Network functions such as the MME, SGW, and PGW are configured to support multiple access technologies simultaneously, allowing a single infrastructure to serve diverse access networks without requiring dedicated systems for each type.
2Adaptability or versatility
If network-specific service control is implemented for different access networks, then service adaptability is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic service control mechanisms that automatically adapt network services based on the access type detected. When a terminal connects, the system dynamically determines whether it's a 3GPP or non-3GPP access and applies appropriate service policies, QoS parameters, and charging rules without requiring static configuration for each access type, thereby maintaining adaptability while simplifying system management.
Solution Approach 2:
The system utilizes parameter changes in signaling messages to differentiate and control services for various access types. By modifying specific parameters in NAS messages and protocol exchanges based on access network type, the system achieves service adaptability through flexible parameter configuration rather than complex structural changes, reducing overall system complexity.

AI summary
A data center adapted to connect via a first wide area network to a core network connected with a base station and to a wireless LAN, variably controls service provided in a virtual core network of the data center to a terminal enabled to select connection to either a wireless LAN or a base station and connect to the data center.
