Indirect network sharing is considered as an innovative network sharing method
which has a broad application prospect and important social value
when achieves the problems in 5G-Advanced (5G-A) network sharing development and promotes the further technology evolution. The current status of the development of network sharing technical standards was introduced
the challenges faced by network sharing operators in the 5G-A phase were analyzed
and the design principles such as new network sharing methods
solutions
and architectural functions were proposed. The features between it and existing technologies in terms of architecture
application scenarios
and sharing modes were compared
and the basic requirements for indirect network sharing applicable to different regions worldwide were put forward. All these were aimed at providing useful references for future research on technologies and business models as well as wider applications.
