-
4g core: control plane components, user plane, tunnneling
-
5g core: functional components, user identity, registration, session ebstablishment
-
contains the network functions (NFs)
-
uses a service-based architecture (SBA) → virtualized functions communicate via APIs:
- AMF (access & mobility management function)
- SMF (sesssion management fucntion)
- UPF (user plane function)
- AUSF (authentication server function)
- PCF (policy control function)
- NRF (network repository function)
- NEF
- UDM
- NSSF
vs 5g RAN
- Radio access network, where gNB is
- gNB links users’ 5G NR device to the 5G core via the NG interface
ip tunnel
- abstract of logical link
3G (void+ceata) at radio network connolllter,

joining a 5g network
this slide is really important 
multi tenancy ???????????????????
this shows shared functions
single core function like AMF, NSSF
both slices have UPF in user plane, SMF, PCF, NRF in control plane
