  6G is the next-generation intelligent and integrated digital information
infrastructure, characterized by ubiquitous interconnection, native
intelligence, multi-dimensional perception, global coverage, green and
low-carbon, native network security, etc. 6G will realize the transition from
serving people and people-things communication to supporting the efficient
connection of intelligent agents, and comprehensively leading the digital,
intelligent and green transformation of the economy and the society. As the
core support system for mobile communication network, 6 6G BSS need to
integrate with new business models brought about by the development of the
next-generation Internet and IT, upgrade from "network-centric" to "business
and service centric" and "customer-centric". 6G OSS and BSS systems need to
strengthen their integration to improve the operational efficiency and benefits
of customers by connecting the digital intelligence support capabilities on
both sides of supply and demand. This paper provides a detailed introduction to
the overall vision, potential key technologies, and functional architecture of
6G BSS systems. It also presents an evolutionary roadmap and technological
prospects for the BSS systems from 5G to 6G.
