    • A method of adjusting a size of a base transceiver station (BTS) search window for adjusting the size of the search window, which the BTS uses to acquire a signal of a mobile station, according to a service radius and modifying a location of the search window, thereby improving efficiency in acquiring an access signal and controlling a service area. The method comprises the steps of: determining a service radius in which the BTS can acquire an access signal of a mobile station; reading a size of a preamble search window and a preamble search range corresponding to the determined service radius from a table used for determination of the size of the search window, the table being stored in a database; and modifying the size of the search window by changing search window parameters of the BTS system according to the read search range and the size of the search window for the preamble.
    • 一种调整基站收发台(BTS)搜索窗口的大小的方法,用于根据服务半径调整BTS用于获取移动台信号的搜索窗口的大小,并修改搜索的位置 从而提高获取访问信号的效率和控制服务区域。 该方法包括以下步骤:确定BTS可以获取移动台的接入信号的服务半径; 从用于确定搜索窗口的大小的表中读取与所确定的服务半径相对应的前导码搜索窗口的大小和前导码搜索范围,该表存储在数据库中; 以及通过根据读取的搜索范围和用于前导码的搜索窗口的大小改变BTS系统的搜索窗口参数来修改搜索窗口的大小。
