5G SA Core, SDM, Policy & Charging

5G SA Core, SDM, Policy & Charging Abstract: 5G rollouts started with the non-standalone (NSA) mode and are now gradually migrating to SA to unleash a plethora of use cases. 5G SA 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 communications service provider (CSP) 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 NFs implemented by CSPs (e.g., UDM, UDR, AUSF, NRF, NEF and NSSF, PCF, BSF, CHF) to enable use cases beyond enhanced mobile broadband (eMBB), fixed wireless access (FWA), and private 5G.
