    • The advantage of the present invention is to provide a sleep mode driving method for reducing power consumption of a portable terminal in a portable Internet system, and to provide the method for the portable terminal to shift into a sleep mode or an awake mode without loss of transmitting and receiving traffic. The portable terminal transmits a sleep mode request message SLP-REQ to the base station, and receives a sleep mode response message SLP-RSP from the base station, so that it can shift to the sleep mode. The portable terminal receives a traffic indication message TRF-IND from the base station during the sleep mode, and shifts to the awake mode. The portable terminal transmits a wake up information message WKUP-INF informing of a normal operation state, and receives downlink traffic from the base station.
    • 本发明的优点是提供一种用于降低便携式互联网系统中的便携式终端的功耗的睡眠模式驱动方法,并且提供便携式终端转入睡眠模式或唤醒模式的方法,而不会丢失 发送和接收流量。 便携式终端向基站发送睡眠模式请求消息SLP-REQ,并且从基站接收睡眠模式响应消息SLP-RSP,从而可以转移到睡眠模式。 便携式终端在睡眠模式期间从基站接收业务指示消息TRF-IND,并转移到唤醒模式。 便携式终端发送通知正常操作状态的唤醒信息消息WKUP-INF,并从基站接收下行流量。

    • A channel scanning apparatus in a portable Internet system establishes a radio link with each of neighboring access points without disconnecting a wireless link with a serving access point and collects radio channel state information of each of the respective neighboring access points. That is, apart from a RF signal processing unit that processes a radio signal from the serving access point, the channel scanning apparatus includes a dedicated scanning processing unit for processing a radio signal of a neighboring access point and measuring radio channel state information of the neighboring access point from the radio signals received by the dedicated scanning processing unit, and collects radio channel state information of the respective neighboring access points. In such a way, communication with the serving access point is not disconnected, and therefore the access terminal and the serving access point do not need to buffer traffic data.
