20090290564 | APPARATUS FOR AND METHOD OF SUPPORTING NETWORK-BASED MOBILITY FOR DUAL STACK NODES - An apparatus for and method of supporting network-based mobility for a dual stack terminal are provided. More particularly, a mobile anchor point (MAP) apparatus for binding and data transmission of a dual stack terminal which has moved from a dual network to an Internet Protocol version 4 (IPv4) network or an Internet Protocol version 6 (IPv6) network, and a method of implementing the MAP apparatus are provided. If the IPv6, which is a next-generation Internet protocol, begins to be applied to networks, a dual stack terminal supporting both the IPv4 and IPv6 will also be introduced. In an environment in which this dual stack terminal moves, movement of the dual stack terminal to an IPv4-only network or an IPv6-only network as well as movement between IPv4/IPv6 dual networks will be considered. According to the apparatus and method, a MAP used in a conventional network-based mobility supporting method is extended. Accordingly, when a dual stack terminal moves between different network-based localized mobility management domains, such as an IPv4-only network or an IPv6-only network, a binding management message is made to be exchanged between two MAPs of the networks, thereby establishing an IPv6-in-IPv4 tunnel or an IPv4-in-IPv6 tunnel between the two MAPs. In this way, even when the dual stack terminal moves to an IPv4-only network or an IPv6-only network, communication with an external terminal is enabled. | 11-26-2009 |
