2. DSMIPv6 Home Network
DSMIPv6 home network is assumed to be dual stack network
provides IPv4 and IPv6 network access HA
v6HA_Addr
v4HA_Addr MN
v6HoA
v4HoA

3. Proposed Extension IPv6 or IPv4 is tunneled as if at foreign network
Extend (add-on) DSMIPv6 to support
To address single version home links (e.g., legacy 3GPP)
IPv4-only Home Network
IPv6-only Home Network
IPv6 or IPv4 is tunneled as if at foreign network HA
v6HA_Addr MN
v6HoA
v4HA_Addr
v4HoA
Global Ipv4/Ipv6
connectivity
IPv4-only home network
IPv6 home network is virtual
IPv6-only home network
IPv4 home network is virtual

4. Basic Idea, possible solution
IPv4 Access NW only
At Home
v4HoA is acquired via DHCPv4
v6HoA is acquired using IKEv2
BU is sent to register v4HoA as CoA of v6HoA
Returning Home
v4 Home Network recognized
BU is sent to
de-register CoA binding of v4HoA
update CoA binding of v6HoA to v4HoA
IPv6 Access NW only
At Home
v6HoA is acquired via ND/DHCPv6
v4HoA is acquired by IKEv2
BU is sent to register v6HoA as CoA of v4HoA
Returning Home
v6 Home Network recognized
BU is sent to
de-register CoA binding of v6HoA
update CoA binding of v4HoA to v6HoA

5. Impact on current operation
Conceptual change + technical change
Protocol operation:
Allow for split of v4HoA and v6HoA binding information in DSMIP BUs
Figure out backward compatibility
