The full coverage of 5G networks in the country marks of the coming of high-speed mobile communications era. Compared to 4G networks, 5G networks deliver higher data rates, lower latency, and more capacity as the network expands. In addition, 5G networks are also different from 4G networks in terms of network architecture and key technologies. 4G changes lives, 5G changes society, and 5G will better empower thousands of industries in the future. 5G is a must-have mobile communication technology for practitioners of Mobile Communications Engineering . This textbook is developed based on the requirements of the Russian Luban Workshop. During the development process, the course standard of “5G Network Formation, Operation and Maintenance and Management” of Tianjin Electronic Information College, Huawei 5G certification system(HCIA-5G and HCIP-5G), and Huawei 5G mobile communication network deployment and operation and maintenance “1+X” certificate system are compared and analyzed, and the knowledge system of “5G Network Formation, Operation and Maintenance and Management” is reconstructed, the knowledge and skill points of each chapter are summarized, and the specific contents of the bilingual textbook resources are planned. This textbook is closely integrated with practical applications and introduces the theoretical knowledge required in the process of 5G network construction, maintenance and management, as well as the professional skills required in practical operation, with the main line of each aspect of network engineering construction and maintenance. The book is divided into five projects, project 1 includes: 5G mobile network overview; communication development history; 5G network architecture; 5G industry division of labor and job knowledge. Project 2 includes: site survey; site pre-construction preparation; project construction management; single station acceptance. Project 3 includes: equipment deployment and connection; parameter planning; 5G parameter configuration; cell parameter configuration; base station inspection and maintenance; base station alarm inspection and coordination processing. Project 4 includes: wireless network optimization process; DT; CQT. Qian Guoliang is the chief editor of the textbook; Liu Cheng, Li Su and Sui Weiyue as the associate editors; and Yuan Guimin, Zhang Liang, Zhao Junying, Liu Miao, Pang Xuelian and Xiao Xiao as the participants. Due to the limited knowledge level and experience of editors, there are inevitably omissions and shortcomings in the book, and we sincerely hope the readers can criticize and correct them.
