Abstract: Provided is a node control apparatus communicating an external Internet Protocol (IP) network and managing a plurality of mobile nodes included in a local network. The node control apparatus manages information relating to the plurality of mobile nodes, each equipped with one or more wireless interfaces, configures one or more groups by classifying the plurality of mobile nodes according to the type(s) of the wireless interface(s) of each of the plurality of mobile nodes, selects a representative node for each of the groups, and allows the member nodes of each of the groups to communicate with the external IP network via their representative node. Therefore, it is possible to minimize power consumption by selectively using a wireless interface for use in connecting to the representative node of each of the groups.

Abstract: A method of acquiring an Internet protocol (IP) address to control a standby mode of a set-top box, and the set-top box and a power management server performing the method are disclosed. The method may include determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked, receiving state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state, and transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information.
