Just to point out that GTP-U also carries control information, which none of the existing *MIP user plane tunnels do not do today.
Regarding GTP-C part, 3GPP TS29.275 has done pretty thorough job already mapping GTPv2-C to PMIP signaling, so using GTP-U instead of GRE or IPIP should be rather straightforward if someone were to do it. - Jouni On Sep 6, 2014, at 1:06 PM, Alper Yegin wrote: > Hi Charlie, > > GTP has its data-plane (GTP-U) and control-plane (GTP-C). > I think you are talking about using Mobile IP signaling in-place of GTP-C to > enable GTP-U. > If so, I think it'd technically work.
