Toward an IPv6 world in mobile networks – mechanisms
... Mobile networks employ GTP to allow terminals to move around while retaining connectivity. Because these tunnels effectively separate the IP networks, an operator can enable IPv6 for subscribers without requiring that every router in its own or its roaming partners’ networks supports IPv6. IPv6-only ...
