摘要： 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.

摘要： A sound reproducing screen for an ultrasonic converting and reproducing method wherein a sound signal is carried on the ultrasonic wave which is transmitted via the screen which has a lattice structure in which a plurality of cells is continuously arranged. Using the screen, the sound signal can be divided from the ultrasonic wave, so that the sound signal can be reproduced. A cell structure of the screen is thus provided for converting the ultrasonic wave into the sound signal by ultrasonic conversion and reproduction which is simple to make and which has a maximum conversion efficiency. Accordingly, an efficiency of reproducing the sound source in a low frequency band as well as a high frequency band is superior, and a realistic three-dimensional sound system can be implemented.

摘要： A method for establishing a path between nodes in a wireless network system. A source node broadcasts a route request (RREQ) packet for a destination node. A mobile node between the source node and the destination node, upon receiving the RREQ packet, appends a redundancy degree with respect to an adjacent node to the RREQ packet and broadcasts the RREQ packet. The destination node selects an optimal path by checking the redundancy degree received along each path when the RREQ packet is received along multiple paths, and the destination node establishes an optimal path to the source node by transmitting a route reply (RREP) packet along the optimal path. Accordingly, the path is established suitable for the quality of service of data to be transmitted and a lost path is promptly recoverable by reference to information stored at each mobile node identifying redundant paths available to the mobile node.
