5G Cell Site Analysis (Positioning)

Re: 5G Cell Site Analysis (Positioning)
Have to learn the paging in 5G for CSA as the TorPEDO attack has an influence on (unknown) Fake Cell Towers in CSA positioning.
#1 My question: Can anybody explain to me the paging in general, its effect on CSA?
#2 Is it important to differentiate between direct and indirect paging in 5G?
#3 Is there a risk of sofrware definded radio paging multi (unaware) Fake Cell Towers?
There is a risk that unaware Fake Cell Towers mismatch a CSA (as its a non-physical/non-proofable approach). I still cannot dive through the crypto key exchange in such an approach.
Any Crypto forensic examiner in the wild?

Re: 5G Cell Site Analysis (Positioning)
Does a mobile recognize if a paging regquest is delayed from genuine source in comparison to a paging request from a fake cell tower?

Re: 5G Cell Site Analysis (Positioning)
The paging runs on PCH Paging CHannel of the physical layer (L1). It seems that a UE cannot detect if after being out of range of a tracking area that it gets paged by a FBS.
Is paging in 5G different from LTE related to crypto?

Can anybody explain how the PCCH and the PCH interwork in 5G?
