5G: What would be the advantage of a network consists of ng-eNB and 5G -core ?

+1 vote

5G network consists of 5G NR and 5G-Core. I came to know that next generation eNB i.e. ng-eNB would support NG interface with 5G-Core. I want to know, which use cases requires such kind of network ?

In some case where operator doesn't want to replace LTE node and cell where they can just improve the protocol to NG-ENB and use the same cell to serve UE, instead of new cell (5G cell) they can use same cell of LTE. This will reduce the deployment cost.Where as core network is easily deployable and it is cost effective (because no environment dependency ) so they can change to 5G -core to support NG-ENB.

I was going through deployment options 4A and 7, in which LTE eNodeB interacts with NGCN for control plane and user plane.
I am thinking the scenarios that when an operator would require particular option 7 in which eNodeB control and user plane both ends interface towards NGCN ? If this is the case then S1-AP and NG-AP both protocols will have to implement at next generation core network.
Is my understanding of option 7 is correct ?
