[Ines] what do you think about this comment?

[Ines]  Based on [1] "...the "Non-Stand Alone" (NSA) architecture, where
the 5G Radio Access Network (AN) and its New Radio (NR) interface is used
in conjunction with the existing LTE and EPC infrastructure Core Network
(respectively 4G Radio and 4G Core), thus making the NR technology
available without network replacement. In this configuration, only the 4G
services are supported, but enjoying the capacities offered by the 5G New
Radio (lower latency, etc)...
...the "Stand-Alone" (SA) architecture, where the NR is connected to the 5G
CN. Only in this configuration, the full set of 5G Phase 1 services are
supported...
... The SA architecture can be seen as the "full 5G deployment", not
needing any part of a 4G network to operate...."

Notice that they are several options of deployment, please see [2] [3] [4]



Thanks,
Ines.
