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 ?

In LTE network, there is no pattern for interface name such as X2, S1-AP, S11, S5/S8, Gx etc. But for the 5G network, it starts alphabet Nx where x denotes 1, 2, 3 as numeric. I could not get the logic behind this doing so. It may be some specific reason for that.
If anyone knows about the reason, please share. Thanks in advance.

A UE can make simultaneous connections with different PGWs with the assumption that each PGW serving different APN.
In this particular case, is it necessary all different PGWs would be communicating with same PCRF ?
