NTELS offers 5G systems, such as NSSF (Network Slice Selection Function) and PCF (Policy Control Function), to SK Telecom and is discussing offerings of CCS (Converged Charging System) as well.

As one of 5G core network functions, NSSF plays a key role in the fulfillment of 5G network requirements, such as the required data size, data rate and latency, for the purposes and in accordance with services provided over a 3GPP-compliant 5G core network, including autonomous driving, immersive media and IoT.
Applicable to various network environments, NTELS’ NSSF selects the set of network slice instances for specific 5G services so that they can be provided in optimal conditions.
