  • Publication number: 20090024726
    Abstract: The present invention relates to a device for a network system and a method of transmitting a profile in a network system. The method provides a user with convenience in remote control and monitoring operation of appliances. By this method, a user, for example, who is locating at home or out-of-home, can control the operation or monitor the operational state of various appliances such as refrigerator or laundry machine through a living network installed at home, such as RS-485 network, a low power RF network, or a power line network. The method according to the present invention further provides a user with effective network service by continuously managing and updating information on all devices constituting the network using a network profile.

  • Publication number: 20080172481
    Abstract: A method of configuring a network profile of a network system is provided. According to the method, a user inside or outside home can control or monitor the operations of appliances such as refrigerator or laundry machine through a living network such as an RS-485 network, a small output RF network, and a power line network provided inside home so that the user can perform remote control and monitor. Also, a network manager configures a network, for example, checks devices connected to the living network, sets logical addresses, and sets other logical node parameters so that it is possible to effectively manage and control all of the devices connected to the network.

  • Publication number: 20070174382
    Abstract: The present invention discloses a home code setting method for a home network system which can overcome a spatial installation limit and improve reliability of network connection. The home code setting method for the home network system includes the steps of connecting a network server to one network, searching for a network at a network device, and when one network is searched for in the search step, performing, at the network device, connection or registration to the network server connected to the network.

  • Patent number: 7124184
    Abstract: A home network system for controlling one or more home appliances connected to a network and a method for operating the same. If an alive message or a connection termination message is normally generated from the home appliance, or if the alive message or the connection termination message is not normally transmitted to a network manager due to a transmission failure in a communication path, the network manager automatically recognizes a network connection state of the home appliance using a network search process, performs a connection termination operation according to the recognized information, and updates network information, resulting in increased reliability and user's convenience of the home network system.
