Kalyani,

I saw that discussion. Non-mobility functions of which deployed on SGi/Gi-LAN types can still be considered as functions deployed in N6.
IMO I couldn’t find that assumption in TS23.501. So it would be a clarification point whether those type of UP functions can be deployed within mobility management data path programmed by SMF utilizing (multiple) N9.

Thought?
[KB] My colleague in SA2 pointed me to section 5.8 in 23.501. 

Cheers,
