Abstract:
PROBLEM TO BE SOLVED: To provide methods and apparatuses for position determination and other operations.SOLUTION: A mobile station 407 uses radio signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination. 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., positions and coverage areas of the wireless access points) for the wireless networks from the collected statistical data.

PROBLEM TO BE SOLVED: To provide methods and apparatuses for position determination and other operations in a combination of a cellular phone network and a satellite positioning system (SPS) in a mobile station.SOLUTION: A mobile station uses wireless signals from a plurality of wireless networks, for position determination, and obtains time and/or frequency information. Further, mobile stations are used to harvest statistical data about wireless access points, namely, the locations of mobile stations that have received signals from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters, and to derive location information, namely, position and service area of the wireless access points, for the wireless networks from the collected statistical data.
Abstract:
PROBLEM TO BE SOLVED: To obtain data to be used for network planning, optimization, validation or operations applications. SOLUTION: A method of obtaining data 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 the 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 data base holding like records relating to other subscriber stations. COPYRIGHT: (C)2011,JPO&INPIT
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:
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.
