5G NSA (EN-DC) Core side call flow and traces

Dear Experts,
Can anyone share the 5G NSA (EN DC) core side call flows and traces.

  1. Registration S6a between MME - HSS for 5G NSA
  2. Data GTP-C create session between SGW - PGW for 5G NSA
  3. Charging Gy between PGW- OCS for 5G NSA

I would like to compare the same with normal 4G to understand the difference in the core side when secondary bearer 5G NR is being added) or how do we distinguish from normal 4G and 5G NSA on the core side.
Thanks & Regards,
