    • A method and a system for measuring a position based on the portable internet by using received signal strength are provided to increase accuracy of a position calculation when a signal is not sufficiently received from peripheral base stations due to strong signals of a main base station, by calculating the position of a terminal according to the strength of a received signal. A position measuring method based on the portable internet in a portable internet system is composed of steps for making a terminal receive information about peripheral base stations from a main base station if a position measuring request is inputted(300); measuring received signal strength about the main base station and peripheral base stations while scanning the peripheral base stations(310); judging whether the received signal strength of the main base station is over a preset critical value or not(320); and determining the position corresponding to an ID(Identification) of the main base station as the position of the terminal if the received signal strength is over a preset critical value.
    • 提供一种用于通过使用接收信号强度来测量基于便携式因特网的位置的方法和系统,以增加由于主基站的强信号而从外围基站不足够地接收到信号时的位置计算的精度,通过 根据接收信号的强度来计算终端的位置。 一种便携式互联网系统中的基于便携式互联网的位置测量方法,包括如下步骤:如果输入了位置测量请求,终端从主基站接收关于外围基站的信息(300); 在扫描周边基站(310)的同时测量关于主基站和外围基站的接收信号强度; 判断主基站的接收信号强度是否超过预设临界值(320); 以及如果所接收的信号强度超过预设临界值,则确定与所述主基站的​​ID(识别)相对应的位置作为所述终端的位置。
