    • Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.
    • 位置确定和其他操作的方法和装置。 在本发明的一个实施例中,移动台使用来自多个无线网络(例如,具有不同的空中接口和/或由不同的服务提供商操作)的无线信号用于位置确定(例如,为了数据通信,用于获得时间和 /或频率信息,用于范围测量,用于扇区或高度估计)。 在本发明的一个实施例中,移动站用于收集关于无线接入点的统计数据(例如,已经从无线接入点接收信号的移动站的位置,诸如来自蜂窝基站,无线局域网接入 点,用于定位信号的中继器或其他无线通信发射机),并从收集的统计数据中导出无线网络的位置信息(例如,无线接入点的位置和覆盖区域)。

    • Signal acquisition assistance data is obtained for receiving devices such as wireless position assisted location devices seeking signals from any source, such as satellite vehicles and base stations. The data may be obtained from previously acquired data, based upon evaluation of changes in parameters such as time and location that may jeopardize validity. In some cases the data may be adjusted for the changes in parameters. Refined data may be calculated by a receiver using partial measurements of signal sets, particularly if the acquisition assistance data provided by a remote entity includes more distinct parameters than have typically been provided. New data need not be obtained until the validity of previous data expires due to limitations upon temporal extrapolation using Doppler coefficients, unless mobile station movement that cannot be compensated is detected, and jeopardizes validity of the previous data.
    • 获得信号获取辅助数据,用于接收诸如无线位置辅助位置设备之类的设备,寻找来自诸如卫星车辆和基站的任何来源的信号。 可以基于对可能危及有效性的诸如时间和位置的参数的变化的评估,从先前获取的数据获得数据。 在某些情况下,可能会根据参数的变化调整数据。 精细数据可以由接收机使用信号组的部分测量来计算,特别是如果由远程实体提供的获取辅助数据包含比通常提供的更多不同参数。 除非先前数据的有效性由于使用多普勒系数的时间外推的限制而过期,否则不需要获得新数据,除非检测到无法补偿的移动台移动,并且危及先前数据的有效性。
