    • An apparatus performs a handoff considering a moving speed of a mobile station in a mobile communication system. A searcher calculates energy of every PN phase in a given search window and reports a detected PN phase to a controller. The controller then determines a moving direction and a moving speed of a mobile station depending on the detected PN phase and a previously detected PN phase, and adaptively determines a pilot received strength threshold used to perform a handoff depending on the determined moving direction and moving speed of the mobile station.
    • 考虑到移动通信系统中移动台的移动速度,装置执行切换。 搜索者计算给定搜索窗口中每个PN相位的能量,并将检测到的PN相报告给控制器。 然后,控制器根据检测到的PN相位和先前检测到的PN相位来确定移动台站的移动方向和移动速度,并根据确定的移动方向和移动速度自适应地确定用于执行切换的导频接收强度阈值 的移动台。
