Feature Description

The same pool of UPs can be used by SAEGW-C and SMF. The user plane can act as UP and UPF at the same time. It can serve SAEGW over the Sx interface and SMF over the N4 interface. The same subscriber IP pool on SAEGW and SMF is supported only with different VRFs.

This functionality is qualified for the user plane acting as UP and UPF to simultaneously support CUPS and SAEGW Sx interfaces (Sxa, Sxb, and Sxab) for 2G, 3G, 4G RAT, and SMF N4 interface for 5G call.

Note

The combined UP and UPF call is not qualified in this release.
