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 ?
