Abstract
A multi-mode terminal (MMT) including a plurality of interfaces which provides access capability to heterogeneous networks respectively to provide quick handover between the heterogeneous networks, is provided. In this instance, when a Binding Update (BU) message is transmitted to a home agent via each of the plurality of interfaces, routers existing in a path to the home agent may update path latency information and path bandwidth information as a Binding Unique Identifier (BID) sub-option extension of Mobile Nodes and Multiple Interfaces in Internet Protocol version 6 (MONAMI6). In this case, the home agent may receive the BU message and select a care-of address (CoA) by referring to path latency information and path bandwidth information, included in the BU message. Also, the home agent may transmit a success binding acknowledgement (BAck) message with respect to the BU message of the selected path.
