As 5G goes far beyond mobile and will eventually become the network that bridges all networks together, with the new sophisticated service-based architecture (5G SBA) designed by the 3GPP. Although many of the network functions (NFs) featured in the 5G SBA come from existing ones currently active in 2G/3G and 4G networks, novel functions such as the network slice selection function (NSSF) are being introduced. Based on a service provider survey and discussions with many vendors, this report analyzes several of the 5G Core SBA functions and provides global and regional market sizes and forecasts by focusing on the most imminent network functions to be implemented by service providers (UDM, UDR, AUSF, and PCF, BSF, CHF).
