Patent ID: 7499732

Claim:
An apparatus for saving power in a mobile communication terminal with an accelerated sleep state, the apparatus comprising: a radio frequency (RF) unit for processing radio signals transmitted between a mobile communication terminal and a base station; and a processor for performing an RX task, a layer 2 task, a main control task and a searcher task, wherein the RX task includes receiving a message from the base station by controlling the RE unit, determining if an address included in the received message is identical to an address stored in the mobile communication terminal, transmitting the received message when the two addresses are identical to each other, and generating a fast sleep command when the two addresses are not identical to each other, the layer 2 task includes transmitting the message received from the RX task, the main control task includes processing the message received from the layer 2 task, and the searcher task includes enabling the mobile communication terminal to shift to a fast sleep state when receiving the fast sleep command from the RX task wherein the RX task includes an addressing sublayer and wherein the addressing sublayer in the RX task is substituted for an addressing sublayer in layer 2 to accelerate entering a sleep state.
