Hi All,

After SN Addition in NSA setup (ENDC 3X), what would be the direction of data in UL direction if my MeNB is in good Radio condition:

UE >MeNB>SgNB>SGW (via SPLIT SCG bearer)
OR
UE>MeNB>SGW (via MCG bearer)

For your regular data/APN: UE >MeNB>SgNB>SGW (via SPLIT SCG bearer)
For your IMS APN: UE>MeNB>SGW (via MCG bearer)
