Abstract: A method of obtaining data useful for one or more network applications is described. The method is performed responsive to a triggering event, such as a dropped call, a position fix, or even expiration of a timer. A position estimate for a subscriber station is obtained responsive to the event. A record is then formed associating the position estimate for the subscriber station with an identifier of the triggering event and/or data measured or obtained responsive to the event, such as the strength of one or more pilots visible to the subscriber station. The record is either stored locally or transmitted to a remote location. In one implementation, the record is transmitted to a remote location, and stored in a database holding like records relating to other subscriber stations.

Abstract: In general, this disclosure is directed to techniques for computing a positioning solution for a mobile unit based on signals received from the satellite navigation system and the wireless communication system. The techniques allow for, and resolve, a synchronization bias that constrains a system time for the satellite navigation system and a system time for the wireless communication system relative to each other. The mobile unit may utilize the defined constraint to compute a position solution in environments where additional independent measurements would otherwise be required. The mobile unit may incorporate Receiver Autonomous Integrity Monitoring (RAIM) functionality to validate the position and time solutions derived from each of received signals. According to the techniques described herein, the mobile unit may be able to utilize the defined synchronization bias to apply RAIM or similar techniques in environments where such techniques would otherwise be indeterminate.

Abstract: In a wireless communication network, base station antenna positions and time offsets are stored in a base station almanac data base along with other information used for obtaining the most reliable mobile station position fixes under a variety of conditions. The system uses the position fixes of mobile stations and terrestrial ranging information to determine base station antenna positions and base station timing offsets. The base station antenna positions are determined during normal mobile station position determinations, in order to maintain and improve the antenna location data, and to correct for change or relocation of the base station antennas. It is possible to recover quickly from a loss of cell sector identity during relocation of a base station antenna, and to ensure accuracy of mobile station position determination based on ranging from the base stations, and rapid acquisition of position data from mobile stations having global satellite receivers.

Abstract: Se describe un metodo para obtener datos utiles para una o mas aplicaciones de red. El metodo se efectua en respuesta al evento iniciador, como la llamada interrumpida, un fijo de posicion, o aun la expiracion de un temporizador. Se obtiene una estimacion de posicion para una estacion de abonado en respuesta al evento. Entonces se forma un registro que asocia la estimacion de la posicion para la estacion de abonado con un identificador del evento iniciador y/o los datos medidos u obtenidos en respuesta al evento, como la fuerza de uno o mas pilotos visibles a la estacion de abonado. El registro es entonces almacenado localmente o transmitido a un lugar remoto. En una implementacion, el registro es transmitido a un lugar remoto y almacenado en una base de datos que contiene registros similares relacionados con otras estaciones de abonado.

Abstract: Methods and apparatuses for location determination in wireless assisted positioning systems. In one aspect of the disclosed method and apparatus, a method to determine a position of a mobile device in a positioning system includes: computing a second estimated position of a mobile device using a first assumed geometric relationship for a location of the mobile device in relation to a navigational transmitter (e.g., a basestation, a pseudolite, or a Satellite Positioning System (SPS) satellite). The first geometric relationship is linearly independent from the altitude of the mobile device (e.g., obtained from an altitude aiding) and a second geometric relationship based on range information (e.g., a range from the mobile device to the navigational transmitter, a pseudorange, an arrival time, or a round trip time) measured with respect to the navigational transmitter. In another embodiment of the disclosed method and apparatus, the method to determine a position of a mobile device in a positioning system includes: determining an estimated clock bias from a strength indicator of a signal transmitted from a navigational transmitter to the mobile device.

Abstract: 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.

Abstract: Different types of position solutions may be used to determine the position of a mobile station (104) in a wireless communication system (101). The position solutions include terrestrial, or network (102, 103), based techniques and non-network, such as satellite (160), based techniques. An apparatus and method whereby different position solutions are selected based on a figure of merit of the different solutions in determining a position of a mobile remote unit (104).
