Hi all
Because combined S-GW/P-GW is one node, so do we still need to implement the connection between them?
Is it necessary for core network to implement GTP-based or PMIP based S5/S8 interface if it is combined S-GW/P-GW?
Is there any 3GPP spec mention about combined S-GW/P-GW? what is the cons and reasons to do this?
thanks
