MEC provides application developers and content providers cloud-computing capabilities and an IT service environment at the edge of the mobile network. This environment is characterized by ultra-low latency and high bandwidth as well as real-time access to radio network information that can be leveraged by applications, including the following services optimization capabilities: ● Content Cache MEC obtains the content of the application servers, including video, pictures, documents etc. and caches locally. During the process of the service, the MEC server analyzes the data came from RN in real time. If the service content of the UE is already in the local cache, the MEC server will push the cache content directly to the terminal. ● Local Streaming Users can directly access the local network through the MEC, the local applications data stream without going through the core network. Local breakout will reduce backhaul bandwidth and the access latency to improve the business experience. ● Business Optimization Through the MEC, the wireless network information can be collected and analyzed in real time, based on the network information to dynamically optimize the services, select the appropriate data rate, content distribution mechanism, congestion control strategy etc.
