Abstract：In order to meet the growing demand of new services and facilitate the application of communication technology in vertical industries, mobile communication networks will gradually evolve with more intelligence, finally resulting in endogenous intelligence in the 6G era. However, most of the current research focuses on artificial intelligence(AI) based transmission and network optimization methods and rarely discusses how to support AI efficiently in the perspective of network architecture design. To fill this gap, this paper introduces the advances in wireless network architectures with endogenous intelligence proposed by both industry and academia and then discusses two use cases as well as related challenges.

Abstract：In this paper, trusted networking is proposed as one of the most important technologies trend in 6G network according to the status of services and applications in 5G network. In 6G network, network trust is proposed as a complementary concept of network security. Compared with network security based on the presumption of guilt, network trust is designed based on the presumption of innocence to prove itself without network attack of threat. Finally, trust requirements in next generation network are analyzed with the trend of higher frequency spectrum, capital expenditure, operational expenditure, and multi-domain integrated, including random access network sharing, space-ground integrated network and massive connection Internet of Things.

Abstract：While 5G network is currently being deployed around the world, number of reserchers and organizations have begun to study 6G. This paper analyzes the challege of 5G network firstly, and then discusses the requirements, version and application scenarios toward 6G, and predicts the key performance indicators of 6G.
