N6-LAN Traffic Steering Through Service Function Chaining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack a detailed method for managing and controlling N6-LAN services using Service Function Chaining (SFC) technology, particularly in 5G networks, which hinders the provision of efficient and customizable additional services.
Innovation Solution
The proposed solution involves configuring a policy control function (PCF) to manage additional information for N6-LAN traffic steering based on policy and charging control (PCC) rules, with a session management function (SMF) creating forwarding action rules (FAR) and a user plane function (UPF) performing SFC encapsulation, enabling direct control of N6-LAN services for specific application traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If Service Function Chaining (SFC) technology is introduced to manage N6-LAN services in 5G networks, then service control capability and traffic steering efficiency are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent segments the N6-LAN service management into distinct functional components: SFC encapsulation units, traffic steering functions, policy control functions, and service function chains. Each component handles specific tasks independently, allowing the complex system to be managed through modular, standardized interfaces while maintaining high automation capability.
2Adaptability or versatility
If detailed SFC encapsulation and traffic steering control are implemented, then service customization and QoS management are improved, but processing overhead and operational complexity increase
Solution Approach 1:
The patent implements universal SFC encapsulation mechanisms that can handle multiple service types and traffic patterns through standardized procedures. The traffic steering function and service function chains are designed to be multi-functional, accommodating different N6-LAN service requirements while maintaining consistent operational interfaces, thus reducing operational complexity despite enhanced customization capability.
3Productivity
If SFC technology is used for N6-LAN traffic steering, then resource utilization and service efficiency are improved, but implementation difficulty and deployment complexity increase
Solution Approach 1:
The patent employs preliminary configuration of service function chains, traffic steering rules, and SFC encapsulation parameters before actual service deployment. Policy control functions pre-establish service templates and resource allocation schemes, allowing rapid service instantiation and reducing on-site implementation difficulty while maintaining high service efficiency.

AI summary
Proposed is a wireless communication system and, more particularly, an apparatus and method for providing a N6-LAN service using SFC in a wireless communication system. A method of supporting an N6-LAN traffic steering function using an SFC technology in a wireless communication system, includes a process in which a policy control function (PCF) configures additional information for N6-LAN traffic steering on the basis of a policy and charging control (PCC) rule, a process of transmitting the configured additional information to a session management function (SMF), a process in which the SMF configures a forwarding action rule (FAR) including the additional information for N6-LAN traffic steering a process in which the SMF transmits the FAR including the additional information to a user plane function (UPF), and a process in which the UPF performs SFC encapsulation on the basis of a predefined SFC policy and the FAR.
