GTI 5G MEC White Paper Summary

Core Content

This white paper outlines the development and deployment of Multi-access Edge Computing (MEC) within the 5G network architecture, emphasizing its role in supporting new services and enhancing the performance of mobile networks. The document highlights the importance of MEC in enabling ultra-low latency, high bandwidth, and intelligent applications, and discusses the industry progress, standardization efforts, business value, and ecosystem development for MEC.

Main Points

1. Introduction to MEC

MEC is a key technology for 5G network transformation, enabling the sinking of applications to the network edge.
MEC reduces bandwidth pressure and latency, supporting services like HD video, VR/AR, and industrial IoT.
It leverages the operator's edge DC as a competitive advantage over OTT providers.
MEC is crucial for new 5G scenarios like IoV, cloud gaming, and smart manufacturing.

2. Industry Progress

4G era: The growth of traffic due to unlimited data packages and OTT CDN deployment pushed operators to deploy local gateways.
5G era: MEC is becoming the basic capability of 5G networks, enabling ultra-low latency and high bandwidth services.
MEC supports new applications like cloud AR/VR, smart hospitals, and smart ports.
MEC is essential for service mobility, ensuring seamless handover between edge controllers and maintaining service continuity.

3. Standard Progress

ETSI MEC redefined MEC as a multi-access edge computing system in 2017, supporting both 3GPP and non-3GPP access.
Phase 2 of ETSI MEC standards includes enhancements like life-cycle management, service APIs, and capability exposure.
3GPP has frozen the Release 15 standard, which fully supports MEC edge network applications.
UPF (User Plane Function) is the key component in the 5G MEC edge network, enabling local breakout, edge mobility, and traffic steering.

4. Business Value and Market Demand

MEC improves user experience, reduces transmission costs, and enhances network efficiency.
It enables new business models and industry applications like video streaming, IoT control, and smart city services.
MEC is positioned as a key enabler for the Internet of Everything (IoE).
China has a strong foundation for MEC commercialization, and GTI members are leading in standardization and pilot projects.

5. MEC Industry Chain

The MEC industry chain includes telecom equipment vendors, operators, IT vendors, third-party applications, and content providers.
Operators are the central players, deploying MEC resources and providing platforms for service and content providers.
Component suppliers and ISVs are essential for customized software solutions and chip support.
Collaboration among industry players is vital for MEC ecosystem development and standardization.

6. MEC Business Progress

GTI has launched MEC pilots in more than 20 cities, promoting industry maturity.
Key pilot projects include:
- Wireless Cache/CDN: Reduced video buffer delay by 20%, increased download speed by 50%, and saved 16% transmission bandwidth.
- AR/VR/HD live video: Achieved 20ms end-to-end delay in Guangdong.
- LBS application: Achieved 5m indoor positioning accuracy in Beijing.
- Cross-layer optimization: Reduced TCP slow start delay by 50%, increased throughput by 30% to 45% in Zhejiang.
MEC is being actively tested and deployed in various vertical industries, with a focus on real-time performance and application integration.

Key Information

MEC is a key enabler for 5G services that require low latency, high bandwidth, and real-time processing.
The 5G MEC architecture is based on Service-Based Architecture (SBA), with SMF and UPF as core components.
Standardization efforts are ongoing, with ETSI and 3GPP leading the way.
GTI is actively involved in international standardization bodies, promoting MEC commercialization and technical innovation.
MEC is expected to support a wide range of applications, including cloud gaming, smart manufacturing, and smart healthcare, through collaboration and ecosystem development.

Structure of the MEC Network Architecture

The MEC system is deployed in different layers of the 5G network, including edge, city, and core.
The core TIC includes group OSS/NFVO, provincial cloud management platforms, and core network functions like AMF, SMF, and MME.
MEC orchestrator interacts with NEF and 5G NFs, acting as an AF (Application Function).
MEC platform is responsible for service management, resource orchestration, and traffic steering.

Conclusion

MEC is a crucial component of the 5G network, enabling new services and enhancing user experience.
The industry is moving towards a unified MEC architecture, with standardization, pilot deployments, and ecosystem collaboration as key drivers.
The GTI is leading the commercialization and technical development of MEC, aiming to establish a world-leading communications infrastructure.
