Gerardo, AFAIK, a rapporteur's role in 3GPP is to merely edit the approved contributions and add it to a document. What you say below is right, that there is no 3GPP-IETF dependency currently on any of the internet drafts proposed for netext. But that is completely irrelevant. You have made it sound it as if 3GPP does not want to work on flow mobility for PMIPv6. FWIW, 3GPP TR 23.861 already has sections on flow mobility solutions when PMIPv6 is used. We can either have 3GPP develop solutions for these sections or have IETF develop them. I prefer the second option. :) I think Frank was referring to the fact that a solution is required to address flow mobility with PMIPv6. He wasn't saying 3GPP needs a particular IETF document.
