    • When a user of a mobile communication terminal makes a request for a position-measuring of a current location, at step S101, a position-measuring method determining section checks a position-measuring method specified. When the method specified is a “cell ID position-measuring”, and it is performed, when the method specified is a “base station radio waves position-measuring”; a base station radio waves position-measuring is performed, when the method specified is a “GPS position-measuring” or a “not specified”, at step S102, a judgment of whether an area in which the mobile communication terminal exist is an area suitable for data communication is made. When the judgment is negative, an autonomous GPS position-measuring is performed. When the judgment is affirmative, an assisted GPS position-measuring is performed. In this case, when the assisted GPS position-measuring has failed, in process to deal with failure of assisted GPS position-measuring at step S108, in a case of predetermined conditions, further the autonomous GPS position-measuring or a supplementary cell ID position-measuring is performed.
    • 当移动通信终端的用户请求当前位置的位置测量时,在步骤S101中,位置测量方法确定部分检查指定的位置测量方法。 当指定的方法是“小区ID位置测量”,并且执行时,当指定的方法是“基站无线电波位置测量”时; 执行基站无线电波位置测量时,当指定的方法是“GPS位置测量”或“未指定”时,在步骤S102,判断移动通信终端存在的区域是否为 进行适合数据通信的区域。 当判断为否定时,执行自主的GPS位置测量。 当判断为肯定时,执行辅助GPS位置测量。 在这种情况下,当辅助GPS位置测量失败时,在步骤S108处理处理辅助GPS位置测量的失败时,在预定条件的情况下,还可以进行自主GPS位置测量或辅助小区ID 进行位置测量。
