Comprehensive Overview of MEC (Multi‑Access Edge Computing) Implementation and Technical Roadmaps in China

The document summarizes the 2022 Edge Computing Best Implementation Whitepaper, emphasizing that MEC spans OT, IT, and CT domains and requires open cooperation among industries to mature the ecosystem. China Telecom plans to drive MEC adoption through a unified alliance, focusing on scenario mining, joint technology breakthroughs, unified network capabilities, business innovation, solution integration, and pilot incubation.

Operator MEC Development Plan : China Unicom has established a nationwide coordination mechanism, creating a MEC business operation center, multiple innovation incubators, and provincial expansion teams. It pursues three directions: building an edge application store ecosystem (China Unicom MEC Lab), deploying a three‑tier edge cloud architecture (central, regional/provincial, and local core/edge nodes), and adopting four deployment models (shared, dedicated, hybrid, and downstream platforms) to support diverse 2B and 2C services such as smart manufacturing, ports, education, healthcare, cloud gaming, and XR.

Industry Ecosystem Status : Gartner predicts a trillion‑yuan market for edge computing by 2025, handling over 75% of data traffic. Telecom operators, public‑cloud providers, equipment vendors, and industrial firms are heavily investing, each pursuing different strategies based on their network and business models.

Technical Route Overview :

1. ETSI‑based MEC : Initiated in 2014, ETSI defines a standardized, open MEC system supporting multiple virtualization technologies, resource orchestration, and service APIs. The architecture includes a MEC host side (MEC host, platform manager, VIM) and a MEC system side (OSS, application lifecycle management, device apps, portal, orchestrator). Typical use cases include enterprise traffic offload, vehicular networking, latency‑sensitive computing, video optimization, IoT aggregation, AR assistance, and video analytics.

2. Public‑Cloud‑Driven MEC : Major Chinese public‑cloud providers (Alibaba, Tencent, Baidu) extend cloud capabilities to the edge, forming a three‑layer hierarchy (cloud, near‑field edge, station edge) and delivering a unified cloud‑edge‑device experience. Lightweight edge platforms (e.g., Huawei IEC, Alibaba ENS) integrate with central clouds for distributed compute and service delivery.

3. Hybrid‑Cloud MEC : Combining telecom network clouds with public clouds, operators like China Mobile propose a unified management framework that supports multi‑cloud orchestration, heterogeneous data exchange, and consistent service delivery across environments. The edge PaaS platform offers foundational middleware (MQTT, Redis), network services (location, QoS), industry‑specific capabilities, application lifecycle management, and comprehensive edge management functions.
