Network Available Terminal's Sleep State Providing System and the Method

The present invention relates to a method and apparatus for providing a sleep (Sleep State) In the device that can be connected to wire or wireless network. The invention To this end the method to provide a sleep state to the network available devices, dynamically in a way that so dramatically reduces the power consumed by determining the optimal parameters by reducing the active state of the network available devices in a sleep state in accordance with the network characteristics and this to provide a unit. And the invention is in providing a sleep state to the network available devices, sleep active use optimal selection of the clock by N, the network available devices activated by not using the clock in the active state to the consuming, depending on the transition to the state in the to provide a way to reduce so drastically reduces the power consumption and apparatus therefor.
