'In which 3GPP specification is UPF defined?
Most of the 5G network functions have dedicated specifications but I could not find any specification specific to UPF. Why is that?
Solution 1:[1]
The N4 interface uses PFCF which is specified in 3GPP TS 29.244 Interface between the Control Plane and the User Plane Nodes.
