Integration of ToB Service and ToC Service for 5G-Advanced Networks

Abstract

The fifth-generation (5G) network enables vertical industries and facilitates the digital and intelligent transformation of industries. However, 5G to business (ToB) and 5G to customer (ToC) cannot be accessed simultaneously by universal terminals, which poses inconvenience to customers in the education, government, cultural tourism. In this paper, a dual-domain fast network (DDFN) with network-side routed selected solution (NRSS) is proposed at the 5G core architecture and process level, which integrates ToB and ToC services for 5G-advanced networks. The DDFN customers can access the local public network and nearby private network simultaneously and imperceptibly with universal terminals at anytime and anywhere. NRSS is a routing scheme of DDFN, which directs various services onto distinct protocol data unit (PDU) sessions. Private network PDU sessions are automatically created when triggered by a particular policy. Compared to universal or standard solutions, NRSS without the upgrade of terminals exhibits superior capabilities in interprovincial roaming and compatibility with various access modes. In summary, NRSS-based DDFN enables service-based diversion without upgrading terminals and wireless infrastructure, which is a potential solution for applications in 5G-advanced industries.
