I went through the call flow diagram that is shown in 23.401 specification and tried to understand data flow (down link and up link both) through indirect data tunnels. I was bit confused that's why post my query here.
While handover procedure is being executed, target MME triggers created indirect data forwarding tunnel request to target SGW what does it means and what is the use of it ?
While doing s1-based handover, indirect data forwarding tunnel procedure may be initiated. What are all position causes to get failure response from SGW ?
My email id is "email@example.com". I am looking for successful S1-handover (with MME and SGW relocation) logs.
Thanks in advance.
