What is MEC?
MEC refers to mobile edge computing. It involves deploying applications, content, and some functions of MBB core network service processing and resource scheduling to the edge of the network close to the access side. Through the processing of services close to users and the cooperation of applications, content, and networks, Provide a reliable, ultimate business experience. Focusing on the MEC business drivers and evolution path that are currently concerned by the industry, this white paper gives the definition of MEC's ​​industrial goals, industry value, key technologies, and network architecture to promote the rapid maturation of the 5G-oriented network technology and architecture.

MEC will bring three changes to the industry:
1. The core network function is deployed close to the user to achieve a completely new experience with extremely low latency. For example, the AR/VR service requires a delay of less than 20ms to eliminate the user's vertigo. 5G proposes an end-to-end delay of 1ms to support autopilot and other services. MEC enables these new services to achieve the ultimate experience by deploying optimized network functions close to the user.
2. Internet content is cached nearby, which saves a lot of transmission resources: According to research, 70% of Internet content in the future can be terminated within the metro area near the user. Saving these contents locally on the MEC platform can save operators 70%. Transmission investment.
3. Network capability open platform to achieve cross-industry cooperation and flexible business innovation: More and more segments want to do industry customization based on telecommunication networks, and provide open platforms through MEC to realize cooperation business innovation in telecommunication industry and vertical industry .
MEC's ​​key enabling technologies include:
1. Full cloudization technology for multi-tenant co-building: Since the deployment location of the MEC is low, the node capacity will be relatively small and cannot depend on the reliability and performance advantages brought by large-scale DCs. Therefore, only NFV is not enough. Introducing a fully-clouded architecture, deploying software functions in different layers according to different capabilities, and achieving high reliability, flexibility, and high performance under limited resources.
2. The control plane is separated from the user plane to implement flexible deployment of network functions: When the MEC is deployed close to the access side, the core network gateway functions are distributed at the edge of the network, resulting in the configuration, docking, and debugging of a large number of interfaces. By separating the control plane of the core network from the user plane, flexible deployment of the gateway can be realized, and the networking can be simplified. At the same time, the concentration of the control plane can resolve the problems such as the detour of the signaling route and the burden on the interface.
3, intelligent business perception and layout: In order to enhance the user experience, MEC deployment nodes need to be able to real-time perception of business and targeted intelligent experience optimization.
With the construction of MEC, mobile networks will bring a series of exciting new ways of office and entertainment. For example: High-definition video experience based on Mobile Content Delivery Network (MCDN), mobile game delivery based on AR/VR and Location Based Service (LBS) marketing, secure and reliable enterprise mobile office based on LBO (Local Break Out), based on MCDN and Open platform smart stadiums, and traffic assist system combined with the car network. New technologies bring new life, let us wait and see!
