Additionnaly some pointers : * 3GPP standard with introduction of IPv4v6, Release 9 : [2/3G] ftp://ftp.3gpp.org/Specs/2010-12/Rel-9/23_series/23060-970.zip [4G] ftp://ftp.3gpp.org/Specs/2010-12/Rel-9/23_series/23401-970.zip * Great IETF draft to put "IP" names on 3GPP concepts and know where it's going : http://tools.ietf.org/html/draft-korhonen-v6ops-3gpp-eps-06 For PDP IPv4v6 & addressing, you probably want to read 9.2.1 & 9.2.2 of 3GPP 23060.
