AI, namely artificial intelligence, is a branch of computer science, and it is a new technical science to study and develop theories, methods, technologies and application systems that simulate, extend and expand human intelligence. Artificial intelligence is not human intelligence, but an information process simulation of human thinking, that is, it can think like human beings, or it can be said to be smarter than human thinking. It can produce intelligent machines, systems, etc. Can make a reaction similar to that of the human brain. The research of artificial intelligence includes intelligent robot, language recognition, language processing and expert system. In fact, many applications on our smart phones belong to AR, such as LBS, face unlocking technology, album classification, voice assistant, photo translation, smart screen recognition and so on. It must be made based on AI technology.

In fact, AI and 5G are a' complementary' relationship. For 5G, AI technology can realize the automation of the 5G core network, and this technology will be applied to the 5G core network to help the 5G core network achieve operation and maintenance and automation. Because the 5G core network will be presented in the form of slices, dozens or even hundreds of slices are definitely unbearable load for the general network.

Therefore, relying on traditional manual operation and maintenance can not meet the construction of 5G network slices at all. At this time, AI technology can be' awesome'. The construction of 5G network slicing can take AI as the core, build an automatic operation and maintenance system, accurately predict network behavior, automatically repair faults, realize slicing in minutes, and monitor network operation. Not only that, in the future 5G era, AI technology can also form accurate insights through independent analysis, and design services that best meet the goals and meet the needs of many people.

As the 5G network will face the public and bring more and richer demand for edge services, MEC has become one of the important technologies of the 5G network. However, AI technology can play a vital role in intelligent edge business scenarios. AI itself is closer to the network' nerve endings' such as data sources and base stations, so it can perfectly cooperate with 5G base stations and edge big data systems.
