摘要： A position determination system and apparatus for utilizing a network of cellular base stations to determine position of a mobile station includes taking a plurality of statistically independent data measurements of the pilot signals from the base stations. Each of the data measurements includes an earliest time of arrival, providing multiple independent measurements for each of the pilot signals. For each cellular base station, a representative measurement is calculated responsive to the independent measurements, which is used to determine position of the mobile station using an AFLT algorithm and/or in conjunction with a GPS algorithm. In some embodiments, the data measurements for each pilot signal further include an RMSE estimate and time of measurement for each time of arrival, and an energy measurement for all resolvable paths. If the mobile station comprises a cell phone, a cell search list and a GPS search list may be provided by a cell base station.

摘要： Systems, apparatuses, and methods disclosed herein allow a requesting party to control use of another user's mobile station. In some aspects, a server is configured to communicate with a plurality of remote computer systems and target mobile stations. The server includes a memory device and a processor configured to access data and logic instructions embedded on the memory device. The server authenticates a requesting party accessing the computer server from one of the remote communication systems. The requesting party is not a user of a selected one of the target mobile stations. The server receives selective availability attributes for the selected one of the target mobile stations from the requesting party. The selective availability attributes indicate conditions under which the target mobile station is enabled or disabled to operate, and features that are available on the target mobile station under a plurality of conditions when the target mobile station is enabled. The server further determines when the target mobile station is operational and downloads the selective availability attributes to the target mobile station when the target mobile station is operational.

摘要： A database for location or geographic based services is secured by requiring location based requests to include a unique identifier that identifies the location as well as an authorization identifier associated with the location. The authorization identifier is information that is obtained by being physically present at the location, such as information from access points that are at the location or a position fix when present at the location. The authorization identifier may be non-unique but relatively time-invariant, making such information easily crowdsourced, but difficult to obtain unless physically present at the location. For example, the authorization identifier may be an SSID or a Beacon Frame, or a hash thereof from one or more devices at the location or a position fix.
摘要翻译：通过要求基于位置的请求来包括标识位置的唯一标识符以及与该位置相关联的授权标识符来保护用于位置或基于地理的服务的数据库。授权标识符是通过物理存在于该位置获得的信息，例如来自存在于该位置的接入点的信息或位于该位置时的位置修正。授权标识符可以是非唯一的但相对时不变的，使得这些信息容易地包围，但是难以获得，除非在该位置处实际存在。例如，授权标识符可以是来自位置处的一个或多个设备的SSID或信标帧或其散列，或位置锁定。
