Anyone having detailed 5G call flow?

Yes there is on Eventhelix → just check Favs.

For eventhelix we have to click on every message one by one to check for important IE’s.

I was specifically looking for a doc with important IE’s on every message.

5G Architecture is a change to cloud from dedicated hardware (specialized hardware). 5G core network moves from 3/4G dedicated hardware to cloud or virtual machines. Radio also moves from dedicated hardware BaseBand Units to CloudRAN or OpenRAN.

Now Mobile Network Operators are not constrained to a single vendor.

Mobile operators can also roll out features faster with a simple software upgrade.
