Abstract
A home network system including one or more electric home appliances connected to a network, each of the electric home appliances periodically transmitting an alive message through the network to inform of the fact that the electric home appliance is in operation, and a home server connected to the network such that the home server transmits/receives messages to/from each electric home appliance via the network to control the electric home appliance while monitoring the status of the electric home appliance. The home server transmits an operation identification request message to the electric home appliance when no alive message from the electric home appliance is received by the home server for a predetermined time. Accordingly, the home network system can identify respective operation statuses of the electric home appliances, and control respective operations of the electric home appliances, while periodically identifying the connection status of the electric home appliances, each of which is maintained in a standby state because there is no associated operation control command received by the home network system, thereby updating operation statuses and connection statuses of the electric home appliances. The invention also provides a method for controlling the home network system. Thus, an enhancement in convenience in using the home network system is achieved.
