Alain Baudot reminds me that some have already outlined the possibility to use tunneling mechanisms (+ ROHC to optimize performances) so as to solve the issue:
-> dual-stack UE connecting to a node via an IPv4 network through IMS
That could be easily an IETF solution but I do not think that 3GPP proposes any mechanism to allocate IPv4 address when required, does it ?
