摘要： A handover reestablishment method capable of effectively re-accessing the serving base station when the mobile terminal fails ranging while moving to the target cell and performs ranging through the handover process, or when the direction of the mobile terminal is changed and thus, the mobile terminal enters into the serving area, is provided. The method includes receiving a handover request message from the mobile terminal; waiting without canceling a connection to the mobile terminal when receiving the handover request message; and performing a reconnection with the mobile terminal when receiving a handover reconnection message from the mobile terminal.
摘要翻译：一种切换重建方法，当移动终端在移动到目标小区并且通过切换过程执行测距时，或者当移动终端的方向改变时，能够有效地重新访问服务基站，并且因此移动终端进入服务区，提供。该方法包括从移动终端接收切换请求消息; 在接收到切换请求消息时等待而不取消与移动终端的连接; 以及当从所述移动终端接收到切换重新连接消息时，与所述移动终端执行重新连接。

摘要： 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.
摘要翻译：便携式因特网系统中的频道扫描装置与每个相邻接入点建立无线电链路，而不断开与服务接入点的无线链路，并且收集每个相邻接入点的无线电信道状态信息。也就是说，除了从服务接入点处理无线电信号的RF信号处理单元之外，信道扫描设备包括专用扫描处理单元，用于处理相邻接入点的无线电信号，并测量邻近接入点的无线电信道状态信息从专用扫描处理单元接收到的无线电信号接收点，并且收集各个相邻接入点的无线电信道状态信息。以这种方式，与服务接入点的通信不会断开，因此接入终端和服务接入点不需要缓冲业务数据。

摘要： 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.
摘要翻译：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。
