IPv6 based CDMA/WLAN heterogeneous network interworking

This paper specifies a mechanism for CDMA/WLAN heterogeneous network interworking based on IPv6. A node with two different link-layer interfaces can select one interface for communicating to another node. When the node moves around networks, it is possible to switch another interface because the node is no more available to use the first selected interface. During this switching of interface, service session must be preserved and duration time of switching must be short not to be recognized by users. And the selection of proper interface must be taken into consideration with many aspects and the point of time of switching must be determined carefully for seamless service
