Thanks Kentaro for you prompt review prior to my announce. :-) > Thank you for updating the draft. Nice to see T.M.Tmap was renamed to > T.M.GTP4.D corresponding to End.M.GTP4.E. :)
It helps to improve consistency of the draft, thanks. > Some feedback about the updated description. > > > 6.6.

Actually no, because it is assumed that the prefix of B’ could be a SID for End.GTP4.E instantiated in SRGW. But you’re correct the B’ doesn’t need to be filled with arg.mob.session.
