摘要： A method and apparatus for estimating whether or not a wireless terminal is indoors are disclosed. The illustrative embodiment employs a pattern classifier that is trained on a plurality of input/output mappings, where each mapping corresponds to a respective location, the output of the mapping is a Boolean value that indicates whether the location is indoors, and the input of the mapping is based on empirical and predicted signal data for the location. In accordance with the illustrative embodiment, a computer-executable program is generated based on the trained pattern classifier. The computer-executable program estimates whether or not a wireless terminal is indoors based on empirical data reported by the terminal, and on a location estimate for the terminal that might be crude or inaccurate (e.g., based on Cell Identifier [Cell-ID], GPS, etc.).

摘要： A method of using a non-GPS-derived technique to estimate the location of an Assisted-GPS-enabled wireless terminal for the purposes of generating location-specific assistance data for the wireless terminal is disclosed. The wireless terminal then uses the assistance data to acquire and process one or more GPS signals and to derive information that is probative of the wireless terminal's location. The GPS-derived location information is then combined with non-GPS-derived location to form an estimate of the location of the wireless terminal that is better than can be derived from either alone. This combination of GPS-derived and non-GPS techniques is particularly useful when the wireless terminal can only acquire one or two GPS signals because it is not possible to determine the location of the wireless terminal with only two GPS signals alone.
摘要翻译：公开了一种使用非GPS导出技术估计辅助GPS功能的无线终端的位置，以便为无线终端生成位置特定辅助数据的目的。然后，无线终端使用辅助数据来获取和处理一个或多个GPS信号，并且导出证明无线终端的位置的信息。然后将GPS导出的位置信息与非GPS导出的位置相结合，以形成无线终端位置的估计，该估计优于单独导出的。当无线终端只能获取一个或两个GPS信号时，GPS导出和非GPS技术的这种组合是特别有用的，因为不可能仅仅使用两个GPS信号来确定无线终端的位置。
