Abstract: Disclosed herein is a home network system interoperable with a wireless terminal of at least one user registered therein, wherein a terminal server is adapted to transmit and receive data to/from the wireless terminal, and a home server is adapted to manage/control a home network and communicate with the terminal server. The terminal server detects the position of the wireless terminal and transmits and receives voice messages, text messages or multimedia data to/from the wireless terminal. The home server is connected with the terminal server over the Internet. The home server sends, to the terminal server, alarm data regarding a dangerous situation in a home where the home network is constructed, receives information regarding the position of the wireless terminal from the terminal server and displays the received position information.

Abstract: A portable device-interoperable home network system includes a home server controls data transmission and reception of an internal network to which a plurality of home appliances are connected in a home. An image server outputs information regarding at least one image in the home to the home server. A portable device server receives the image information from the image server via the home server and transfers it to a portable electronic device. Therefore, a user can recognize a situation in the home through the portable electronic device from anywhere outside of the home, resulting in an increase in convenience of use.

Abstract: A home appliance network system and a method for operating the same. The home appliance network system enables a home server to detect a connection state between individual home appliances and a network, such that it can automatically assign an IP address. The home appliance network system includes: a plurality of home appliances connected to a network implemented to perform a home-appliance networking function; and a home server for initially assigning an IP (Internet Protocol) address identifying the home appliances, assigning a local IP address when the home appliances are not connected to the network, and automatically resetting an IP address when the home appliances are re-connected to the network. The home appliance network system can assign a local IP address to a home appliance such that the home server can control the home appliance even though a current network connection state is indicative of a non-connection state.
