Hi Matsushima-san,
I have some other questions on your draft.
Referring to Steps 14 and 15 in Figure 4, in Step 14, Route Update (I guess
BGP Route Update) is initiated by which node and is going to which node?
In Step 15 you have EPC-E initiating this and it is going towards RTR. Why
is this not sufficient? i.e. since EPC-E can detect mobility?
Why do you need Step 14?
For the uplink traffic from UE, you seem to assume that it is always
towards RTR. Could it not be directed to another UE? What happens in that
case?
You say that
EPC-E supports the user
plane functions of SGW and PGW.
So there is no PGW in your design, I mean no anchor PGW?
What happens to the control plane functions of SGW and PGW? Where are they?
Regards,
Behcet
