Abstract
A control method for a mobile terminal which connects to a router linked to an external network through at least one interface, including receiving a router advertisement message from the router through a first interface, determining whether prefix information of the received router advertisement message is identical with prefix information of a preset internet protocol (IP) configuration reuse group including the first interface, and generating an IP configuration of the first interface when the two prefix information are identical. Accordingly, at the time of a vertical handover, continuity of the A/V session can be maintained without having to use mobile IP technology.
