Abstract:
PURPOSE: A data transfer method for saving energy is provided to save energy of a network system by reducing energy consumption of a network device. CONSTITUTION: A network system activates a network relay module in a virtual line(110). The network system transfers data from a source to a destination along with a transfer route through a route table of the network relay module(120). The network system eliminates the virtual line between the source and the destination. The network system automatically switches the network relay module into an energy saving state(130).
Abstract:
PURPOSE: An energy consumption device of a communication relay system and a method thereof are provided to automatically convert a communication relay system mode into an idle mode at low traffic time by analyzing the amount of traffic request by time. CONSTITUTION: A signal sensing unit(110) senses a signal request received to a communication relay system. A time calculating unit(120) calculates signal absence time. A state converting unit(130) converts a current system state into an idle mode or a sleep mode A signal detection unit(140) detects a wake-up signal] about the communications translation system.
Abstract:
PURPOSE: An apparatus and method for selecting the cell size of a communication relay system according to the portability of a terminal are provided to switch the mode of the communication relay system into a power saving mode. CONSTITUTION: A cell size control unit(120) converts the cell coverage of a communication relay system into a first cell size or a second cell size according to the mobility of a terminal. A mode controlling unit(130) sets up the power saving mode about the communication relay system. The mode control unit sets up an active mode about the communication relay system.
