1. SMF sends SmfInfo(S-NSSAI, DNN, TAI) to the NRF
2. NRF responds to AMF with SmfInfo during NF-Discovery.
3. AMF selects SMF based on S-NSSAI, DNN and TAI in SmfInfo.
#
Note that if there is no SmfInfo, any AMF can select this SMF.
#
o S-NSSAI[SST:1] and DNN[internet] - At least 1 DNN is required in S-NSSAI

WHO: MNO & Buisness customer WHAT: MNO deploys separete slice for specific customer in order to provide independent network connectivity to customer's local resources. WHY: APN routing is limited and complicated for MNO and requires equipment reconfiguration. Slicing looks more convenient and easy to deploy.
Configure deployment of slicing scenario with additional eUPF in separate slice. Choose slice based on specific STT/SD.
