With the large-scale commercial launch of fifth generation (5G) mobile network, the development of new services and applications catering to the year 2030, along with the deep convergence of information, communication, and data technologies (ICDT), and the lessons and experiences from 5G practice will drive the evolution of the next generation of mobile networks. This article surveys the history and driving forces of the evolution of the mobile network architecture and proposes a logical function architecture for sixth generation (6G) mobile network. The proposed 6G network architecture is termed SOLIDS (related to the following basic features: soft, on-demand fulfillment, lite, native intelligence, digital twin, and native security), which can support self-generation, self-healing, self-evolution, and self-immunity without human involvement and address the primary issues in the legacy 5G network (e.g., high cost, high power consumption, and highly complicated operation and maintenance), significantly well.

随着第五代（5G）移动网络的大规模商用、面向 2030 年的新业务和应用的发展，以及信息、通信和数据技术（ICDT）的深度融合，以及经验教训和5G 实践经验将推动下一代移动网络的演进。本文调查了移动网络架构演进的历史和驱动力，并提出了第六代（6G）移动网络的逻辑功能架构。提出的 6G 网络架构称为 SOLIDS（涉及以下基本特征：软、按需实现、精简、原生智能、数字孪生和原生安全），可支持自生成、自愈、自进化,
