Patent ID: 8208486

Claim:
An energy-aware home gateway based on a network protocol, comprising: a network matching module for performing a physical network interface function on a home network and an external network; a processor module for performing an operation function and a control function of an overall system in a normal active state in which service traffic exists; a memory module used as a system memory of the processor module; a service function module controlled by the processor module and performing a service function depending on a use state of a user, the service function module including service function sub-modules; a network protocol agent module for processing control traffic in an idle state in which no service traffic exists; and a power supply module for supplying power to the overall system in the normal active state and for supplying power to the network matching module, the memory module, and the network protocol agent module in the idle state, wherein the processor module individually performs a power control on each of the service function sub-modules in the normal active state based on an operation state of the service function module, the operation state is determined based on the use state of the user, so that power to a part of the service function sub-modules is supplied or interrupted.
